Abstract
Description
Technical Field
[0001] This invention belongs to the field of front-end application development technology, and in particular relates to a method for implementing high-performance route parsing and dynamic optimization in the React framework. Specifically, it relates to a method for organizing and maintaining route configuration, parsing and matching route requests, and dynamically loading, caching and updating the corresponding components of routes in a single-page application (SPA). Background Technology
[0002] With the widespread adoption of Single Page Applications (SPAs) in front-end scenarios such as enterprise management systems, e-commerce platforms, and content platforms, front-end routing mechanisms are used to map browser addresses to page view components to achieve refresh-free navigation and state persistence. Within the React framework, routing is typically accomplished through route configuration (including path rules, component references, permission information, redirect relationships, etc.) and route resolution and matching logic, further collaborating with on-demand loading, caching, and build toolchains to meet the engineering requirements of initial screen loading, interactive responsiveness, and continuous iteration.
[0003] In existing technologies, for small to medium-scale routing scenarios, sequential traversal or regular expression-based matching methods are commonly used to parse and match route configurations. However, as the number of route entries increases, the path hierarchy deepens, and the number of dynamic parameter paths grows, route matching often requires comparing a large number of candidate rules, leading to increased navigation latency and unstable page switching responses. Furthermore, route configurations are typically maintained in a nested structure. While this facilitates expressing parent-child relationships, it can lead to problems such as high traversal overhead, coarse update granularity, and complex maintenance during runtime, especially when performing fast lookups, incremental change merging, and partial updates. Consequently, it is difficult to simultaneously achieve matching efficiency and configuration maintainability in complex projects.
[0004] Meanwhile, React SPAs often rely on code splitting and dynamic import to load routing components on demand. However, when there are many routing components, large differences in component size, and a clear long-tail distribution of user access paths, existing technologies are prone to the following problems: First, the component loading strategy is too simplistic, making it impossible to achieve a stable balance between "first-screen speed, hit rate, network overhead, and build cost"; Second, there is a lack of effective cache management mechanisms, which may lead to cache bloat and uncontrollable memory usage during long-term operation, affecting page stability; Third, when route configurations or component resources change, it often relies on a complete re-deployment or full refresh, making it difficult to achieve fine-grained online updates during runtime, thus affecting iteration efficiency and user experience.
[0005] For the reasons mentioned above, there is an urgent need for a method that can achieve high-performance route resolution and dynamically optimize route loading and runtime updates within the React framework. Summary of the Invention
[0006] To address the challenges faced by existing Single-Page Applications (SPAs) within the React framework as route size increases, path hierarchy deepens, and dynamic parameters grow, issues arise such as decreased route parsing and matching efficiency, unstable navigation response, inadequate on-demand loading strategies for route components, difficulty in controlling cache usage, and the reliance on full deployments or refreshes for configuration or resource changes, which limit iteration efficiency and user experience. This invention provides a method for achieving high-performance route parsing and dynamic optimization within the React framework. The aim is to improve route parsing and page switching performance, reduce loading overhead, enhance operational stability, and increase online iteration efficiency by collaboratively optimizing the organization and maintenance of route configurations, the parsing and matching of route requests, the dynamic loading of route components, cache management, and online updates.
[0007] To achieve the above objectives, this invention provides a method for implementing high-performance route resolution and dynamic optimization in the React framework, comprising:
[0008] The routing configuration is preprocessed to generate a set of routing records associated with the routing path, and an index structure for route matching is constructed.
[0009] When a routing request is received, the routing request is parsed and matched based on the index structure to determine the target routing record;
[0010] The routing component acquisition process is triggered based on the target route record. The routing component acquisition process includes: acquiring routing component resources from the multi-level loading source according to priority based on the cache hit result, and updating the cache after successful acquisition; wherein, the routing component resources include component code and its dependent resources;
[0011] The system receives incremental change information related to the routing record set through a push-type change channel, generates an updated index structure and / or an updated routing record set based on the incremental change information, and generates resource version mapping information corresponding to the updated routing record set.
[0012] A double-buffering or snapshot switching mechanism is adopted to atomically switch the updated index structure, the updated set of routing records, and the corresponding resource version mapping information as the same effective version to form a new currently effective version; wherein, an effective version tag is generated and associated for the effective version.
[0013] During a route request processing, the effective version flag of the currently effective version is passed to the route component acquisition process, so that the determination of the target route record and the acquisition of the route component resources are completed under the same effective version, thereby avoiding incorrect loading caused by inconsistency between the index version and the resource version during dynamic updates.
[0014] Furthermore, the preprocessing includes: recursively traversing the nested routing structure, concatenating the complete paths of each routing node as keys, and using component identifiers, loading entry points, and routing metadata as key values to generate a set of routing records; wherein the set of routing records is implemented using a routing dictionary data structure; and performing conflict detection on the keys, outputting conflict indication information when path conflicts are detected to ensure the uniqueness of routing records.
[0015] Furthermore, the index structure is a radix tree index structure; when constructing the radix tree index structure, the path is divided into a sequence of segments according to the delimiter, and the common prefixes are compressed and merged to reduce the number of nodes and the tree depth;
[0016] When no target route record is matched based on the radix tree index structure, a preset fallback processing strategy is executed. The fallback processing strategy includes at least one of the following: returning to a preset error page component, falling back to a preset safe route, or outputting a matching failure indication message.
[0017] Furthermore, parameter nodes are constructed for path segments containing dynamic parameter segments, and parameter constraint rules are extracted to generate regular expressions; the regular expressions are cached and maintained, and the regular expressions are called during route matching to complete parameter validation and output parameter values.
[0018] Furthermore, the multi-level loading source includes at least a memory caching layer, a network distribution layer, and a runtime loading layer; the routing component acquisition process, based on the effective version flag, determines the target resource version corresponding to the target routing record from the resource version mapping information, and executes:
[0019] a) Query the memory cache layer using the cache key determined by the routing path and the target resource version;
[0020] b) When the memory cache is not hit, a resource acquisition request carrying the version of the target resource is sent to the network distribution layer;
[0021] c) When the network distribution layer fails to obtain or is unavailable, the runtime loading layer is triggered to load the routing component resource corresponding to the target resource version; when the runtime loading fails or is not applicable, an alternative acquisition path is triggered to obtain the routing component resource or component loading information consistent with the target resource version.
[0022] The alternative acquisition path includes at least one of the following: retrieving routing component resources from the source server, obtaining a redirect resource address, or obtaining a component manifest / loading description information, and associating the redirect resource address or component manifest / loading description information with the target resource version to ensure version consistency during dynamic updates.
[0023] Furthermore, the runtime loading layer triggers on-demand loading by calling the runtime loading interface of the module packager to generate component code blocks in the routing component resources; and establishes a correspondence between the component code blocks and the routing path and the target resource version for subsequent cache hits.
[0024] Furthermore, the cache includes at least a memory cache and a persistent cache; the memory cache adopts a least recently used eviction policy and sets an expiration control policy for cache items; when a cache item meets the eviction or expiration conditions, the cache item is migrated from the memory cache to the persistent cache or invalidation is cleaned up; wherein, the cache item carries at least resource version information, and the routing path corresponding to the cache item and the resource version information are used together to distinguish cache items, so as to support the differentiated management of different resource versions.
[0025] Furthermore, it also includes a preloading step: listening to page scrolling and identifying the route path corresponding to the navigation entry within the viewport threshold range, and performing preloading on the corresponding route component; the preloading task is executed with low priority through an idle scheduling mechanism, and at the start of preloading, the effective version flag of the current effective version is obtained and the target resource version is determined accordingly, so that the cache written by preloading is consistent with the current effective version.
[0026] Furthermore, the push-type change channel is a WebSocket channel; the incremental change information includes routing records corresponding to newly added paths, deleted paths, and / or replaced paths, and / or includes routing component resource update instructions associated with the routing records;
[0027] After receiving the incremental change information, the client performs node-level insertion, deletion, and / or replacement updates on the index structure based on the incremental change information to form the updated index structure, and generates resource version mapping information corresponding to the updated set of routing records; and when receiving the routing component resource update instruction, if the resource version carried by the cached item is inconsistent with the target resource version corresponding to the target routing record in the resource version mapping information, the cached item is invalidated, so as to trigger the re-acquisition and loading of routing component resources consistent with the newly effective version when accessing the target routing record in the future.
[0028] Furthermore, the double-buffering or snapshot switching mechanism includes: constructing a new version index structure, a new version routing record set, and corresponding new version resource version mapping information in the background buffer; after construction, switching the effective pointer to the new version in one go; and performing version-based release or delayed release on the old version resources after the atomic switch. The delayed release includes: maintaining the old version index structure and old version resource version mapping information available during the grace period, so that the routing matching and resource acquisition process that started before the switch can complete the loading based on the captured old version effective version flag, thereby avoiding the mixing of indexes and resources in concurrent navigation and dynamic update scenarios.
[0029] To address the issues in the background technology, such as insufficient route matching efficiency, potential version inconsistencies between route resolution and component resource acquisition during dynamic incremental updates, insufficient fault tolerance in component loading chains, and the lack of version-level management in caching leading to false hits and redundant overhead, this solution employs the following techniques: preprocessing route configuration and constructing a route matching index structure; using double buffering of the same version for the index structure / route record set / resource version mapping information and performing atomic switching while generating and transmitting effective version markers; providing multi-level loading sources and backup acquisition paths; and establishing versioned cache keys based on route paths and target resource versions, combined with cache governance and preloading scheduling. These techniques result in at least the following beneficial effects:
[0030] By preprocessing route configurations and building a route matching index structure associated with route paths (e.g., an index organization method that compresses common prefixes), the traversal and comparison overhead in the route matching process can be reduced, which helps to reduce the matching latency of navigation requests and improve matching throughput, thereby improving scalability when the route scale increases.
[0031] By atomically switching the updated index structure, the updated set of route records, and the corresponding resource version mapping information as the same effective version, and generating an effective version marker, the effective version marker is used throughout the route matching and route component resource acquisition process when processing a single route request. This ensures that the determination of the target route record and the determination of the target resource version have a consistent version basis, which helps to reduce the risk of incorrect loading, blank screen, or abnormal route jump caused by version inconsistency during dynamic incremental updates.
[0032] By providing multi-level loading sources and introducing a runtime loading layer and alternative acquisition paths when the network distribution layer is unavailable or fails to acquire resources, the availability of component resources can be maintained under conditions such as network fluctuations, distribution anomalies, or cache invalidation, which helps improve routing success rate and system availability.
[0033] By determining the cache key using the routing path and the target resource version, and establishing a correspondence between component code blocks and the corresponding routing path and target resource version, it is possible to distinguish cache items of different versions, which helps to reduce cache misses or reuse errors caused by version overwriting. Furthermore, when combined with cache management strategies such as LRU and expiration control, it helps to reduce the bandwidth and computing power consumption caused by repeated downloads and loading, thereby improving the stability and smoothness of page switching.
[0034] By extracting constraint rules from dynamic parameter segments and generating regular expressions, and caching and maintaining these regular expressions, the overhead of repeatedly compiling regular expressions can be reduced, which helps improve the matching stability and performance consistency of routes containing dynamic parameters.
[0035] By listening to user actions to identify navigation entry points and triggering preloading tasks, and by using an idle scheduling mechanism to execute preloading with low priority, the cache can be filled in advance without significantly affecting the main thread interaction. At the same time, the target resource version is determined based on the effective version tag during the preloading process, which helps to reduce the risk of inconsistency between the preloaded product and the actual navigation version, thereby reducing the waiting time and lag during actual navigation.
[0036] By building a new version in the background and switching the effective pointer at once through double buffering / snapshotting, and releasing or delaying the release of the old version, it helps to reduce race conditions and abnormal interruptions caused by update switching under concurrent conditions, and improves the stability and predictability of the system in high-concurrency interaction scenarios.

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0038] Figure 1 This is a flowchart illustrating the implementation method of routing resolution and dynamic optimization in this invention. Detailed Implementation
[0039] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.
[0040] like Figure 1 As shown, this embodiment provides a method for implementing high-performance route resolution and dynamic optimization in the React framework, including:
[0041] The routing configuration is preprocessed to generate a set of routing records associated with the routing paths, and an index structure for route matching is constructed. This preprocessing is preferably performed during application initialization or in the background processing phase after routing configuration changes to reduce the real-time computational overhead of route matching during runtime. The set of routing records can be stored using a dictionary mapping to support quick location of routing records based on the routing path.
[0042] When a routing request is received, the routing request is parsed and matched based on the index structure to determine the target routing record; wherein, the parsing and matching includes: performing prefix matching on static path segments, performing parameter validation and parameter value extraction on dynamic parameter segments, and using the extracted parameter values as input for subsequent component loading and page rendering.
[0043] The routing component retrieval process is triggered based on the target route record. The routing component retrieval process includes: retrieving routing component resources from multi-level loading sources according to priority based on cache hit results, and updating the cache after successful retrieval; wherein, the routing component resources include component code and its dependent resources; wherein, the dependent resources may include style resources, configuration resources and / or manifest information required for operation that are associated with the component code block; and, the routing component retrieval process may trigger retry or rollback processing when retrieval fails, in order to maintain the availability of the navigation process.
[0044] The system receives incremental change information related to the routing record set via a push-based change channel. Based on this incremental change information, it generates an updated index structure and / or an updated routing record set, and generates resource version mapping information corresponding to the updated routing record set. The incremental change information can be encoded according to three types of operations: addition, deletion, and replacement, so that the client can complete node-level updates without rebuilding the entire index structure. The resource version mapping information is used to bind routing records to their corresponding routing component resource versions.
[0045] A double-buffering or snapshot switching mechanism is employed to atomically switch the updated index structure, the updated routing record set, and the corresponding resource version mapping information as the same effective version, forming a new currently effective version. An effective version marker is generated and associated with this effective version. Preferably, the atomic switching is implemented through a one-time replacement of the "effective pointer / reference" to avoid intermediate states where some structures are updated while others remain in the old version during the switching process. The effective version marker can be a monotonically increasing version number, a timestamp, a hash value, or a combination thereof.
[0046] During a routing request process, the effective version flag of the currently effective version is passed to the routing component acquisition process. This ensures that the determination of the target routing record and the acquisition of routing component resources are completed under the same effective version, thereby avoiding erroneous loading caused by inconsistencies between the index version and the resource version during dynamic updates. The "passing" can be achieved by carrying the effective version flag in the routing request context. The routing request context may include fields such as the routing path, parameter values, target routing record identifier, and effective version flag.
[0047] As one implementation method, the preprocessing in this embodiment includes: recursively traversing the nested routing structure, concatenating the complete paths of each routing node as keys, and using component identifiers, loading entry points, and routing metadata as key-value pairs to generate a set of routing records; wherein the set of routing records is implemented using a routing dictionary data structure; and performing conflict detection on the keys, outputting conflict indication information when path conflicts are detected to ensure the uniqueness of routing records. The routing metadata may further include permission identifiers, page titles, whether authentication is required, and configuration items for displaying loading status, etc.; the conflict detection is preferably performed when constructing the routing dictionary to expose configuration errors as early as possible during development or release. The routing dictionary can be used as one implementation form of the set of routing records.
[0048] As one implementation method, the index structure described in this embodiment is a radix tree index structure. When constructing the radix tree index structure, the path is divided into a sequence of segments according to the delimiter, and the common prefixes are compressed and merged to reduce the number of nodes and the tree depth. The compression and merging of the common prefixes is used to reduce the tree structure level and the number of node hops, thereby helping to maintain the stability of matching latency under large-scale routing configuration. Furthermore, priority access order or weight information can be set for nodes corresponding to high-frequency routing paths to further reduce the matching cost of commonly used paths.
[0049] When no target route record is matched based on the radix tree index structure, a preset fallback handling strategy is executed. This fallback strategy includes at least one of the following: returning a preset error page component, falling back to a preset safe route, or outputting a matching failure indication message. The fallback strategy may further include recording matching failure logs, reporting monitoring events, and triggering route configuration synchronization checks without affecting user interaction, to facilitate locating abnormal configurations or update delay issues. As one implementation, this embodiment constructs parameter nodes for path segments containing dynamic parameter segments and extracts parameter constraint rules to generate regular expressions. The regular expressions are cached and maintained, and during route matching, the regular expressions are called to complete parameter validation and output parameter values. The parameter constraint rules can be explicitly declared by the developer in the route configuration; if not declared, preset default rules can be used to ensure basic validity validation of parameter segments. The cache maintenance of the regular expressions can use a memory-mapped table to store the correspondence between parameter node identifiers and regular expression objects to reduce runtime recompilation overhead.
[0050] As one implementation method, the multi-level loading source in this embodiment includes at least a memory caching layer, a network distribution layer, and a runtime loading layer; the routing component acquisition process, based on the effective version flag, determines the target resource version corresponding to the target routing record from the resource version mapping information, and executes:
[0051] a) Query in the memory cache layer using a cache key determined by the route path and the target resource version; wherein the cache key may further include a component identifier or a component code block identifier to reduce the probability of conflict between different components under the same route path template.
[0052] b) When the memory cache misses, a resource retrieval request carrying the target resource version is initiated to the network distribution layer; wherein, the network distribution layer may be a content delivery network or an edge caching system; the resource retrieval request can be implemented by carrying the target resource version in the request parameters, request headers or resource URL, so that the returned resource is consistent with the target resource version.
[0053] c) When the network distribution layer fails to acquire or is unavailable, the runtime loading layer is triggered to load the routing component resource corresponding to the target resource version; when the runtime loading fails or is not applicable, an alternative acquisition path is triggered to acquire the routing component resource or component loading information consistent with the target resource version; wherein, when a network anomaly occurs, a limited number of retries and backoff waiting can be performed according to a preset strategy; and, the runtime loading layer can be used to fill the gap caused by the unavailability of the network distribution layer in scenarios with local module packages or offline resources.
[0054] The alternative acquisition path includes at least one of the following: retrieving routing component resources from the source server, retrieving a redirected resource address, or retrieving component manifest / loading description information. The redirected resource address or component manifest / loading description information is associated with the target resource version to ensure version consistency during dynamic updates. The component manifest / loading description information may include component code block identifiers, dependencies, and verification information bound to the target resource version, thus facilitating the client to load complete dependencies according to the version even under the alternative path.
[0055] As one implementation method, the runtime loading layer in this embodiment triggers on-demand loading by calling the runtime loading interface of the module bundler to generate component code blocks in the routing component resources; and establishes a correspondence between the component code blocks and the routing path and target resource version for subsequent cache hits. The on-demand loading can be code-segmented loading triggered by a dynamic import mechanism; furthermore, the "routing path template and parameter values" can be standardized and used as part of the component identifier to facilitate more accurate cache reuse and isolation in dynamic parameter routing scenarios.
[0056] As one implementation method, the cache in this embodiment includes at least a memory cache and a persistent cache. The memory cache employs a least recently used eviction policy and sets an expiration control policy for cached items. When a cached item meets the eviction or expiration conditions, it is migrated from the memory cache to the persistent cache or invalidated and cleaned up. Each cached item carries at least resource version information, and the routing path corresponding to the cached item, along with the resource version information, is used to distinguish cached items, supporting differentiated management of different resource versions. The persistent cache can be browser-side persistent storage. Furthermore, different expiration and cleanup policies can be set according to the resource type of the cached item to reduce the impact of jitter on critical routing components.
[0057] As one implementation method, this embodiment also includes a preloading step: monitoring page scrolling and identifying the routing paths corresponding to navigation entries within the viewport threshold range, and performing preloading on the corresponding routing components; the preloading task is executed with low priority through an idle scheduling mechanism, and at the start of preloading, the effective version flag of the currently effective version is obtained and the target resource version is determined accordingly, so that the cache written by preloading is consistent with the currently effective version. The viewport threshold range can be a preset distance interval near the viewport; furthermore, preloading can be triggered only for navigation entries that meet preset conditions to avoid resource waste caused by invalid preloading; the idle scheduling mechanism can allocate execution segments when the main thread is idle, thereby reducing the impact on user interaction.
[0058] As one implementation method, the push-type change channel in this embodiment is a WebSocket channel; the incremental change information includes routing records corresponding to newly added paths, deleted paths, and / or replaced paths, and / or includes routing component resource update instructions associated with the routing records; wherein, the incremental change information may further include a change batch identifier and its corresponding effective version marker, so that the client can apply the changes in batches and form a consistent update view.
[0059] After receiving the incremental change information, the client performs node-level insertion, deletion, and / or replacement updates on the index structure based on the incremental change information to form the updated index structure, and generates resource version mapping information corresponding to the updated set of routing records. When receiving the routing component resource update instruction, if the resource version carried by the cached item is inconsistent with the target resource version corresponding to the target routing record in the resource version mapping information, the cached item is invalidated. This triggers the re-acquisition and loading of routing component resources consistent with the newly effective version when accessing the target routing record subsequently. The invalidation of the cached item may include marking it as invalid, delayed deletion, or immediate deletion. When using delayed deletion, it is preferable to combine effective version marking with version isolation of the cached item to avoid concurrent requests reading information that does not meet the version mapping.
[0060] As one implementation method, the double-buffering or snapshot switching mechanism in this embodiment includes: constructing a new version index structure, a new version routing record set, and corresponding new version resource version mapping information in a background buffer; switching the effective pointer to the new version all at once after construction; and performing version-based release or delayed release on the old version resources after the atomic switch. The delayed release includes: maintaining the availability of the old version index structure and old version resource version mapping information during a grace period, so that the route matching and resource acquisition process that started before the switch can complete loading based on the captured old version effective version flag, thereby avoiding the mixing of indexes and resources in concurrent navigation and dynamic update scenarios. The grace period can be set according to the longest estimated time of concurrent navigation on the client; and reference counting or active request statistics can be performed before the old version is released to reduce resource consumption while ensuring concurrency consistency.
[0061] By preprocessing the route configuration and building a radix tree-based matching index structure, combined with a versioned component acquisition process using multi-level loading sources, and a push-based incremental update and double-buffered atomic switching mechanism, route matching, component resource acquisition, and dynamic updates are completed collaboratively under the same effective version. This helps reduce the matching overhead in large-scale routing scenarios and improves the consistency of indexes and resources and navigation stability during dynamic updates. Example
[0062] This embodiment provides an implementation method for React framework route parsing and dynamic optimization in conjunction with Embodiment 1, which further explains the steps of route configuration preprocessing, index structure construction, dynamic component loading, hot update and cache management.
[0063] In this embodiment, the routing configuration preferably adopts a flattened approach. Specifically, the nested routing structure is transformed into a standardized dictionary mapping to achieve flattened management of routing configuration. By recursively traversing the original nested routing tree, the complete path of each routing node is concatenated as the key name, and routing metadata (including component references, permission identifiers, loading status, etc.) is written into the routing dictionary as key-value pairs. This transformation process is preferably completed during the application initialization phase, so that runtime path matching can avoid recursive lookups in the nested structure, thereby helping to reduce runtime overhead during the matching phase. In addition, in dynamic routing scenarios, new routing rules can be incrementally injected into the routing dictionary and used in conjunction with subsequent version switching mechanisms to achieve smooth activation.
[0064] In this embodiment, the index structure used for route matching is preferably a radix tree index structure. During construction, the route path is split into a sequence of segments according to delimiters and tree nodes are created. Common prefixes are compressed and merged to reduce the number of nodes and the tree depth. For dynamic parameter segments, dedicated parameter nodes are used for storage, and regular expression constraints can be associated for parameter validation. During matching, positioning is completed by hopping through the tree structure level by level. Compared to sequential traversal, this helps maintain the stability of matching latency as the route size increases. Furthermore, the access order of frequently used paths can be optimized based on access statistics or preset strategies to reduce the average matching cost of common navigation routes.
[0065] In this embodiment, the processing of dynamic parameter segments may include the compilation and caching of regular expression constraints. Specifically, dynamic parameter segments in the path are identified and developer-defined regular expression constraints are extracted; regular expressions are pre-compiled and cached in a memory mapping table during the preprocessing or index building stage; default validation rules are injected into parameter segments without explicitly defined constraints to avoid repeated compilation at runtime and ensure the basic legality of parameter values. During route matching, the cached regular expressions are called to complete parameter validation and output parameter values for use in subsequent component loading and rendering.
[0066] In this embodiment, routing component resources are preferably acquired using a dynamic code segmentation and on-demand loading mechanism, so that component resources are loaded only when needed. To improve version consistency and cache hit accuracy, component identifiers can be generated for routing components, and a multi-level loading chain of "memory cache layer—network distribution layer—runtime loading layer" can be constructed: loaded component code blocks are read first from the memory cache; if no match is found, component resources with the same version as the target resource are obtained from the network distribution layer; if still unsuccessful, the runtime loading interface of the module bundler is called to trigger on-demand loading to generate component code blocks and write them to the cache. Furthermore, directory-level dynamic import can be supported to adapt to the organization of routing components with path parameters; combined with a scroll-triggered preloading strategy, corresponding resources can be preloaded when the user approaches the navigation entry point, thereby helping to reduce waiting time during actual navigation.
[0067] In this embodiment, under dynamic parameter routing scenarios, the "routing path template and parameter values" can be standardized to generate component identifiers, which are used to more accurately distinguish component resources and cache items corresponding to different parameter combinations. Component identifiers can be generated using hashing or other repeatable deterministic encoding methods; when conditions permit, they can be executed in a background thread to reduce the impact on the main thread. The above-mentioned component identifier generation is an optional enhancement measure used to improve cache isolation and hit accuracy.
[0068] In this embodiment, when a component fails to load, a preset rollback strategy can be executed to improve robustness. For example, a limited number of retries can be performed with a backoff wait; or, if necessary, a preset error page component / error boundary component can be rendered, and the current routing state can be retained to prompt the user to resume the operation. During the rollback and retry process, it is preferable to still use the resource version obtained based on the effective version tag constraint to reduce the risk of version mismatch during dynamic updates.
[0069] In this embodiment, preloading can reduce interaction waiting time. Specifically, page scrolling events are monitored, navigation entries within the viewport threshold range are identified and their corresponding route paths are extracted, and the corresponding route components are preloaded and written to the cache. The preloading task is preferably executed with low priority through an idle scheduling mechanism to reduce the impact on main thread interaction; and the currently effective version flag is captured at the start of preloading to determine the target resource version, so that the cache written by preloading is consistent with the currently effective version.
[0070] In this embodiment, a push-based change channel can be established to receive incremental update information for route configuration changes. The incremental update information may include route records corresponding to newly added / deleted / replaced paths, as well as update instructions related to route component resources. Upon receiving the information, the client can perform node-level insertion, deletion, and replacement updates on the cardinality tree, and construct a new version index structure, route record set, and resource version mapping information in the background buffer. After construction, a one-time switch is performed through a double-buffering or snapshot mechanism, and the effective version flag constrains the parsing and resource acquisition of subsequent route requests, thereby reducing the risk of index and resource misuse in concurrent navigation and dynamic update scenarios.
[0071] In this embodiment, cache governance can be implemented by combining eviction and expiration policies. Memory cache can employ a Least Recently Used (LRU) eviction policy combined with TTL expiration control; when a cache item meets the eviction or expiration conditions, it is migrated to persistent cache or invalidation cleanup is performed. Persistent cache can be cleaned up as needed through a delete interface to control storage usage. Cache items preferably carry resource version information, which, along with the routing path, is used to distinguish cache items, supporting differentiated governance and reclamation of different resource versions.
[0072] In this embodiment, a routing state machine can be introduced as an optional extension to manage the navigation lifecycle and uniformly handle authentication, component loading, rendering, and error handling. The state machine can output loading progress, error reasons, and rollback results to facilitate unified permission interception and loading prompts; this extension is not a necessary condition for implementing the technical solution described in Embodiment 1.
[0073] Based on Example 1, this embodiment provides optional implementation details for routing flattening, radix tree matching, parameter constraint caching, on-demand loading, multi-level degradation and rollback, preloading, push-based hot updates, and cache reclamation. This enables each step to work collaboratively around the effective version tag and versioned cache key, thereby helping to further improve version consistency, resource acquisition robustness, and overall operational stability in dynamic update scenarios.
[0074] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

The routing component acquisition process includes: acquiring routing component resources from the multi-level loading source according to priority based on the cache hit result, and updating the cache after successful acquisition; wherein, the routing component resources include component code and its dependent resources; The system receives incremental change information related to the routing record set through a push-type change channel, generates an updated index structure and / or an updated routing record set based on the incremental change information, and generates resource version mapping information corresponding to the updated routing record set. A double-buffering or snapshot switching mechanism is adopted to atomically switch the updated index structure, the updated set of routing records, and the corresponding resource version mapping information as the same effective version to form a new currently effective version; wherein, an effective version tag is generated and associated for the effective version; During a route request processing, the effective version flag of the currently effective version is passed to the route component acquisition process, so that the determination of the target route record and the acquisition of the route component resources are completed under the same effective version, thereby avoiding incorrect loading caused by inconsistency between the index version and the resource version during dynamic updates.
2. The method according to claim 1, characterized in that: The preprocessing includes: recursively traversing the nested routing structure, concatenating the complete paths of each routing node as keys, and using component identifiers, loading entry points, and routing metadata as keys to generate a set of routing records; wherein the set of routing records is implemented using a routing dictionary data structure; and performing conflict detection on the keys, outputting conflict indication information when path conflicts are detected to ensure the uniqueness of routing records.
3. The method according to claim 1 or 2, characterized in that: The index structure is a radix tree index structure; when constructing the radix tree index structure, the path is divided into a sequence of segments according to the delimiter, and the common prefixes are compressed and merged to reduce the number of nodes and the tree depth; When no target route record is matched based on the radix tree index structure, a preset fallback processing strategy is executed. The fallback processing strategy includes at least one of the following: returning to a preset error page component, falling back to a preset safe route, or outputting a matching failure indication message.
4. The method according to claim 3, characterized in that: Parameter nodes are constructed for path segments containing dynamic parameters, and parameter constraint rules are extracted to generate regular expressions. The regular expressions are cached and maintained, and the regular expressions are called during route matching to complete parameter validation and output parameter values.
5. The method according to claim 2, characterized in that: The multi-level loading source includes at least a memory caching layer, a network distribution layer, and a runtime loading layer; the routing component acquisition process, based on the effective version flag, determines the target resource version corresponding to the target routing record from the resource version mapping information, and executes: a) Query the memory cache layer using the cache key determined by the routing path and the target resource version; b) When the memory cache is not hit, a resource acquisition request carrying the version of the target resource is sent to the network distribution layer; c) When the network distribution layer fails to obtain or is unavailable, the runtime loading layer is triggered to load the routing component resource corresponding to the target resource version; when the runtime loading fails or is not applicable, an alternative acquisition path is triggered to obtain the routing component resource or component loading information consistent with the target resource version. The alternative acquisition path includes at least one of the following: retrieving routing component resources from the source server, obtaining a redirect resource address, or obtaining a component manifest / loading description information, and associating the redirect resource address or component manifest / loading description information with the target resource version to ensure version consistency during dynamic updates.
6. The method according to claim 5, characterized in that: The runtime loading layer triggers on-demand loading by calling the runtime loading interface of the module packager to generate component code blocks in the routing component resources; and establishes a correspondence between the component code blocks and the routing path and the target resource version for subsequent cache hits.
7. The method according to claim 1 or 5, characterized in that: The cache includes at least a memory cache and a persistent cache; the memory cache adopts a least recently used eviction policy and sets an expiration control policy for cache items; when a cache item meets the eviction or expiration conditions, the cache item is migrated from the memory cache to the persistent cache or invalidation is cleaned up; wherein, the cache item carries at least resource version information, and the routing path corresponding to the cache item and the resource version information are used together to distinguish cache items, so as to support the differentiated management of different resource versions.
8. The method according to claim 1, characterized in that: It also includes a preloading step: listening to page scrolling and identifying the route path corresponding to the navigation entry within the viewport threshold range, and performing preloading on the corresponding route component; the preloading task is executed with low priority through an idle scheduling mechanism, and the effective version flag of the current effective version is obtained when preloading starts and the target resource version is determined accordingly, so that the cache written by preloading is consistent with the current effective version.
9. The method according to claim 1, characterized in that: The push-type change channel is a WebSocket channel; the incremental change information includes routing records corresponding to newly added paths, deleted paths, and / or replaced paths, and / or includes routing component resource update instructions associated with the routing records; After receiving the incremental change information, the client performs node-level insertion, deletion, and / or replacement updates on the index structure based on the incremental change information to form the updated index structure, and generates resource version mapping information corresponding to the updated set of routing records; and when receiving the routing component resource update instruction, if the resource version carried by the cached item is inconsistent with the target resource version corresponding to the target routing record in the resource version mapping information, the cached item is invalidated, so as to trigger the re-acquisition and loading of routing component resources consistent with the newly effective version when accessing the target routing record in the future.
10. The method according to claim 1, characterized in that: The dual-buffering or snapshot switching mechanism includes: constructing a new version index structure, a new version routing record set, and corresponding new version resource version mapping information in a background buffer; switching the effective pointer to the new version all at once after construction; and performing version-based release or delayed release on the old version resources after the atomic switch. The delayed release includes: maintaining the availability of the old version index structure and old version resource version mapping information during the grace period, so that the routing matching and resource acquisition process that started before the switch can complete the loading based on the captured old version effective version flag, thereby avoiding the mixing of indexes and resources in concurrent navigation and dynamic update scenarios.
