Description

Technical Field

[0001] This invention relates to the field of front-end engineering and intelligent code generation technology, specifically to a method and system for automatically generating Vue component code based on Figma design drafts. Background Technology

[0002] In modern front-end engineering, transforming visual interface design results into underlying machine-readable and browser-parsable code files is a standard step in software development. As the complexity of front-end interface interactions grows exponentially, development workflows typically undergo a deep evolution from static layout nodes to dynamic component architectures. Related technologies usually employ a multi-level parsing framework when handling design file parsing and code generation tasks. Specifically, this approach first traverses and extracts node coordinates and hierarchical information from the design file, solidifying them into structured intermediate-layer data. Subsequently, a unified domain-specific language is introduced for intermediate state description, uniformly translating all structured data into platform-independent abstract syntax units. Finally, a static template engine is used to convert these abstract syntax units into platform-specific layout code.

[0003] However, in real-world scenarios involving multi-terminal collaboration and high-frequency interaction, the aforementioned data flow links exhibit hidden technical flaws. To maintain multi-platform compatibility, the general intermediate description layer employs feature dimensionality reduction during abstraction, physically stripping away implicit view variant logic, state transition sequences, and micro-interaction flows between components from the design source files. This forced smoothing of the framework's unique dynamic semantics results in output code files possessing only a static visual layout. When handling high-concurrency data updates or complex cascading operations, the underlying logic is prone to disruptions, preventing synchronization between state nodes and leading to memory scheduling chaos and rendering process crashes. Furthermore, existing code generation processes lack targeted design for system configuration and component matching, and their disclosure of key parameters and core algorithm logic is insufficient. Issues include narrow Slot recognition trigger conditions, unclear attribute interface type constraints, and inaccurate similarity calculation descriptions, resulting in poor code adaptability, low reusability, and an inability to meet the demands of efficient front-end engineering development.

[0004] To address the above issues, a method and system for automatically generating Vue component code based on Figma design drafts is proposed. Summary of the Invention

[0005] To address the aforementioned technical issues, this paper provides a method and system for automatically generating Vue component code based on Figma design drafts. This technical solution resolves the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A method for automatically generating Vue component code based on Figma design drafts includes:

[0008] Obtain the design draft node tree and identify the component definition nodes and component instance nodes associated with the component definition nodes in the design draft node tree;

[0009] Extract the variant attribute set of the component definition node, and extract the prototype interaction links for each variant attribute in the variant attribute set;

[0010] A state response mapping logic is constructed based on the variant attribute set, and a component communication event associated with the state response mapping logic is constructed based on the prototype interaction link;

[0011] The spatial nesting relationship of the design draft node tree is traversed, and the content variation characteristics of the component instance nodes are identified to generate a content distribution slot structure.

[0012] Based on the preset design system configuration, the component instance nodes are matched with the target visual component library to select suitable standard components;

[0013] Based on the state response mapping logic, the component communication events, the content distribution slot structure, and the matched standard components, view framework code in single-file component format is directly generated. The view framework code includes mutually isolated template structure areas, script logic areas, and style declaration areas.

[0014] Preferably, the logic for constructing the state response mapping based on the variant attribute set includes:

[0015] Iterate through each attribute key-value pair in the variant attribute set;

[0016] If the key name of the attribute key-value pair is detected to match the preset status identifier feature library, the status identifier feature library contains three core status identifiers: state, status, and mode, and can also be expanded to include other status-related key names according to actual development needs;

[0017] Then initialize the corresponding reactive state variables in the script logic area;

[0018] Extract the key-value enumeration list from the attribute key-value pairs, map the key-value enumeration list to the valid value space of the reactive state variable, and set the first element of the key-value enumeration list as the initial loading value of the reactive state variable.

[0019] Preferably, the step of constructing component communication events associated with the state response mapping logic based on the prototype interaction link includes:

[0020] Extract the trigger source node, target node, and trigger action features from the prototype interactive link;

[0021] If it is determined that the trigger action feature is associated with a state switching operation within the variant attribute set, then an event listening instruction is attached to the element node corresponding to the trigger source node within the template structure area.

[0022] An event callback processing flow is constructed in the script logic area. The event callback processing flow includes assignment mutation operations for the reactive state variable. The data source for the assignment mutation operations is the variant attribute mapped to the target node.

[0023] Preferably, the step of traversing the spatial nesting relationship of the design draft node tree and identifying the content variation characteristics of the component instance nodes to generate a content distribution slot structure includes:

[0024] For the same component definition node, extract the first component instance nodes and second component instance nodes of all its subordinate levels;

[0025] Compare the child node topology trees of the first component instance node and the second component instance node;

[0026] If a shift in the structural features of a child node topology tree is detected, or if inconsistent content features of text nodes on the same topology path are detected, or if a text node contains a preset placeholder keyword, including {{}}, {{slot}}, {{content}}, and [placeholder content], then the region that has shifted or contains the placeholder keyword is marked as a volatile content domain.

[0027] Based on the hierarchy depth and space occupancy of the variable content domain in the component definition node, a corresponding named slot declaration is generated in the template structure area.

[0028] Preferably, before directly generating the view framework code in single-file component format based on the state response mapping logic, the component communication events, and the content distribution slot structure, the method further includes:

[0029] Iterate through all variant attributes of the component instance node and calculate the value distribution matrix of each variant attribute in different component instance nodes;

[0030] If it is detected that the first variant attribute has a constant value across all instance dimensions in the value distribution matrix, then the first variant attribute is marked as a constant feature;

[0031] If a second variant attribute is detected to have an overwrite operation that deviates from the baseline value in the value distribution matrix, the second variant attribute is marked as a configurable interface feature, and a corresponding attribute interface declaration is generated in the script logic area. The attribute interface declaration covers attribute type constraints and required state constraints. The attribute type constraints include TypeScript type inference logic, and the TypeScript type inference logic includes the union type LiteralUnion.

[0032] Preferably, the step of directly generating view framework code in single-file component format based on the state response mapping logic, the component communication events, and the content distribution slot structure includes:

[0033] Calculate the similarity distribution parameters between the features of sub-components in the design draft node tree and the features of standard components in the target visual component library;

[0034] The similarity distribution parameter is obtained by weighting the name edit distance parameter and the Jaccard similarity parameter of the attribute set. The weighting calculation formula is as follows:

[0035] ;

[0036] In the formula, The input Figma component to be matched. To design a system component library, This is the weighting coefficient, with a value ranging from 0.3 to 0.7. for and The overall similarity score, The attribute similarity function has a preset convergence threshold range of 0.6-0.8.

[0037] When there is a standard component whose similarity distribution parameter is greater than the preset convergence threshold, the standard component is directly referenced in the template structure area.

[0038] Map the style identifier to the vision system configuration dictionary to obtain the corresponding theme variable code;

[0039] A style block with a scope isolation identifier is generated in the style declaration area, and the hard-coded style values ​​are replaced with the theme variable code within the style block.

[0040] Preferably, after generating the view frame code in single-file component format, the method further includes:

[0041] Perform dependency graph analysis on all state variables and method bodies in the script logic region;

[0042] Identify clusters of mutually referencing variables and methods in the dependency graph. If the call frequency of the cluster exceeds a preset threshold and has a complete data loop, then the cluster is removed from the script logic area.

[0043] The extracted cluster is encapsulated as an independent composite logic function, and a dependency import instruction pointing to the composite logic function is inserted in the script logic area.

[0044] Preferably, the state response mapping logic includes one-way data binding logic and two-way data binding logic; the process of constructing the two-way data binding logic includes:

[0045] Identify whether the component instance node has a preset form interaction feature type;

[0046] If the form interaction feature type is present, a two-way reactive state variable bound to the target input value is automatically constructed, and a two-way binding instruction stream is generated in the template structure area.

[0047] Preferably, the content distribution slot structure further includes:

[0048] If the content variation features are identified to cover iterative operations on the underlying dynamic dataset, then the data source variables on which the iterative operations depend are extracted.

[0049] Generate a scope slot structure and attach the data source variable as an exposed parameter to the property set of the scope slot structure.

[0050] A Vue component code auto-generation system based on Figma design drafts, comprising:

[0051] The design draft node recognition module obtains the design draft node tree and identifies the component definition nodes and component instance nodes associated with the component definition nodes in the design draft node tree.

[0052] The variant attribute and interaction link extraction module extracts the variant attribute set of the component definition node, and extracts the prototype interaction links for each variant attribute in the variant attribute set;

[0053] The state and communication logic construction module constructs state response mapping logic based on the variant attribute set, and constructs component communication events associated with the state response mapping logic according to the prototype interaction link;

[0054] The content distribution slot generation module performs spatial nesting relationship traversal on the design draft node tree and identifies the content variation characteristics of the component instance nodes to generate a content distribution slot structure.

[0055] The component matching module, based on the preset design system configuration, matches the component instance nodes with the target visual component library and filters out suitable standard components;

[0056] The Vue single-file component code generation module directly generates view framework code in single-file component format based on the state response mapping logic, the component communication events, the content distribution slot structure, and the matched standard components. The view framework code includes mutually isolated template structure areas, script logic areas, and style declaration areas.

[0057] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0058] This invention directly parses the interaction links between component variants and prototypes in Figma design drafts, preserving view state logic and interaction sequence, avoiding the loss of dynamic semantics caused by traditional intermediate description layers, and generating code with complete dynamic response capabilities;

[0059] Based on multi-instance node topology comparison, it automatically identifies content variation areas and generates slot structures, eliminating the need for manual configuration of slot positions and nesting relationships. This significantly improves component reusability and code structure rationality, and reduces development and configuration costs.

[0060] By automatically distinguishing between constant and configurable properties through the distribution of variant property values, and generating component interfaces with type constraints, the design specifications and front-end code specifications are unified, reducing the cost of later maintenance and secondary modifications.

[0061] By introducing a component library similarity matching and theme variable mapping mechanism, standard components can be directly reused and hard-coded style values ​​can be replaced, improving code compatibility and scalability while ensuring visual style consistency.

[0062] Dependency graph analysis and combinatorial function encapsulation are performed on script logic to avoid spaghetti code accumulation, optimize code structure and runtime performance, and reduce the risk of memory scheduling and rendering anomalies.

[0063] It supports two-way form binding and automatic generation of scope slots, and can directly adapt to dynamic lists and complex interaction scenarios, achieving one-stop output from high-fidelity design drafts to runnable Vue single-file components. Attached Figure Description

[0068] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0069] Example 1, referring to Figure 1-4 As shown, a method for automatically generating Vue component code based on Figma design drafts includes:

[0070] S1, Obtain the design draft node tree, and identify the component definition nodes and component instance nodes associated with the component definition nodes in the design draft node tree;

[0071] S2, extract the variant attribute set of the component definition node, and extract the prototype interaction link for each variant attribute in the variant attribute set;

[0072] S3, construct state response mapping logic based on the variant attribute set, and construct component communication events associated with the state response mapping logic according to the prototype interaction link;

[0073] S4, perform spatial nesting relationship traversal on the design draft node tree, identify the content variation characteristics of the component instance nodes to generate a content distribution slot structure;

[0074] S5. Based on the state response mapping logic, the component communication event, and the content distribution slot structure, directly generate view framework code in single-file component format. The view framework code includes mutually isolated template structure area, script logic area, and style declaration area.

[0075] In some embodiments, obtaining the design draft node tree and identifying component definition nodes and associated component instance nodes in the design draft node tree includes: loading the hierarchical topology data of the design draft into memory by calling a preset application programming interface (API); establishing a node traversal cursor and extracting node type labels using a depth-first traversal algorithm; instantiating the component definition node when the type label is detected as being in a defined state, and instantiating the component instance node when the type label is detected as being in a reference state. The topology data returned by the API directly maps the spatial arrangement and logical nesting of interface elements. Specifically, for each instantiated component instance node, the system extracts its unique identifier field and constructs a memory addressing pointer in memory pointing to the corresponding component definition node, thereby establishing a complete parent-child inheritance and reference dependency graph and avoiding link breaks during subsequent state resolution.

[0076] Based on the aforementioned node identification results, this invention differs from conventional static attribute extraction methods by constructing a parsing mechanism that delves into dynamic logic.

[0077] In some embodiments, extracting the variant attribute set of the component definition node and extracting the prototype interaction links for each variant attribute in the variant attribute set includes: scanning the state vector space inside the component definition node and extracting attribute key-value pairs representing different visual or interactive states; deserializing the prototype connection data of the design draft and restoring the jump or switching relationship matrix of the node under specific triggering conditions.

[0078] Among them, the variant property set reflects the physical state boundaries that the component may present at different lifecycle stages.

[0079] Specifically, for the extraction of interactive links, drilling down to the coordinate hotspot range of the trigger source, the identifier of the target response node, and micro parameters such as trigger latency, these parameters are packaged into independent interactive event feature clusters to provide data support for the subsequent reconstruction of component communication links.

[0080] Specifically, the coordinate hotspot range of the trigger source is determined by extracting the absolute coordinates, width, and height parameters of the trigger node in the design draft, accurate to the pixel level, ensuring that the subsequently generated event listening instructions can be accurately bound to the corresponding interface elements; the identifier of the target response node is consistent with the unique identification code of the component definition node and the component instance node, realizing the accurate association between the interaction link and the node dependency graph; the trigger latency parameter is extracted according to the value set in the design draft prototype. If the design draft does not explicitly set it, the default trigger latency is 0ms. At the same time, event type labels, such as click, hover, double-click, etc., are added to the interaction event feature cluster to distinguish different interaction triggering methods; in addition, the jump condition parameters in the interaction link are also extracted. If there is a condition jump, such as a jump triggered only when a specific state is met, the condition parameter is also included in the event feature cluster, providing complete parameter support for the subsequent construction of the event callback processing flow.

[0081] In some embodiments, constructing state response mapping logic based on a variant attribute set includes: traversing each attribute key-value pair in the variant attribute set; if the key name of the attribute key-value pair matches a preset state identifier feature library, initializing the corresponding reactive state variable in the script logic area; extracting the key-value enumeration list from the attribute key-value pair, mapping the key-value enumeration list to the legal value space of the reactive state variable, and setting the first element of the key-value enumeration list as the initial loading value of the reactive state variable.

[0082] Among them, the state identifier feature library pre-stores keyword sequences that represent state switching. These keyword sequences are used to determine the dynamic attributes of attributes at the lexical level.

[0083] Specifically, the initialization process of reactive state variables involves attaching reference binding primitives to the script area nodes of the underlying abstract syntax tree. This allows the variable to be captured by the framework's dependency collection mechanism during subsequent compilation, ensuring that if the data undergoes a memory mutation at runtime, the view layer can achieve precise redrawing at the nanosecond level.

[0084] Specifically, the reference binding primitives are encapsulated using Vue's `ref` or `reactiveAPI`, automatically selecting the binding method based on the type of the property key-value pair: if the property value is a basic data type, such as a string, number, or boolean, then `refAPI` is used for binding; if the property value is a complex data type, such as an object or array, then `reactiveAPI` is used for binding. Simultaneously, when initializing reactive state variables, type annotations are added to explicitly define the variable's type constraints, ensuring consistency with the subsequently generated property interface declarations. Furthermore, the key-value enumeration list is deduplicated, removing duplicate keys and values ​​to ensure the uniqueness of the valid value space. If the key-value enumeration list is empty, a default empty value is set as the initial load value, and exception handling code is added to the script logic area to prevent runtime value retrieval anomalies.

[0085] In some embodiments, constructing component communication events associated with state response mapping logic based on prototype interaction links includes: extracting the trigger source node, target node, and trigger action features from the prototype interaction links; if it is determined that the trigger action features are associated with state switching operations within the variant attribute set, then attaching an event listening instruction to the element node corresponding to the trigger source node in the template structure area; and constructing an event callback processing flow in the script logic area.

[0086] The event callback processing flow includes assignment mutation operations for reactive state variables, and the data source for these assignment mutation operations is the variant attribute mapped to the target node.

[0087] Specifically, by physically binding listening instructions and event callback streams, a closed loop of control flow from the user input end to the memory state end is achieved.

[0088] Specifically, event listener instructions automatically select the corresponding instruction type based on the characteristics of the triggering action. For example, a click event is bound to the v-on:click instruction, and a hover event is bound to the v-on:mouseenter instruction. Event modifiers are also added to the listener instructions. If the prototype design specifies requirements such as preventing event bubbling or preventing default behavior, the corresponding modifiers are added. The event callback processing flow uses function encapsulation. The function name follows the format of handle + triggering action + target node identifier to ensure the standardization and recognizability of the function name. Inside the callback function, the validity of the variant property mapped to the target node is first validated to confirm that the property value is within the valid value space of the reactive state variable. Then, the assignment mutation operation is performed. After the assignment is completed, the framework's dependency update mechanism is triggered, driving the view layer to redraw synchronously. In addition, if the prototype interaction links involve cross-component communication, component communication API call code is added to the callback processing flow to achieve state synchronization between components.

[0089] In some embodiments, the design draft node tree is traversed in a spatial nesting relationship, and the content variation characteristics of component instance nodes are identified to generate a content distribution slot structure. This includes: for the same component definition node, extracting all the first and second component instance nodes of its subordinate levels; comparing the child node topology trees of the first and second component instance nodes; if the structural features of the child node topology tree are detected to be offset, or the content features of text nodes on the same topology path are detected to be inconsistent, then the offset area is marked as a volatile content domain.

[0090] The comparison of child node topology trees relies on strict node path hash calculation to ensure that the comparison process has constant time complexity.

[0091] Specifically, based on the hierarchical depth and space occupancy of the variable content domain in the component definition node, a corresponding named slot declaration is generated in the template structure area. This mechanism automatically determines the code structure by calculating the topological divergence of different instances, realizing a direct physical mapping from interface polymorphism to the underlying slot architecture, and breaking through the efficiency bottleneck of manually configuring slot positions.

[0092] Specifically, the hierarchy depth is determined by the nesting level of the node in the design draft node tree, starting from the direct child node of the component definition node. The hierarchy depth determines the nesting position of the slot in the template structure area. Space placement is determined by extracting parameters such as the width, height, margins, and positioning method of the variable content field to ensure that the generated slot can accurately match the display range of the variable content field. Named slots are named in the format of slot plus hierarchy depth plus variable content field identifier to avoid slot name conflicts. If there are multiple variable content fields under the same component definition node, corresponding named slots are generated for each, and slot annotations are added to the template structure area to indicate the function of each variable content field. In addition, if the variable content field involves dynamic content iteration, placeholder code related to the v-for directive will be added to the named slot to prepare for subsequent binding of dynamic datasets.

[0093] In some embodiments, based on state response mapping logic, component communication events, and content distribution slot structure, view framework code in single-file component format is directly generated, including: assembling the constructed underlying syntax features into an abstract syntax tree; and deconstructing the abstract syntax tree and outputting it to mutually isolated template structure area, script logic area, and style declaration area according to the single-file component specification of the target front-end framework.

[0094] The template structure area is responsible for carrying document object model nodes and slot placeholders, the script logic area is responsible for managing memory status and communication interfaces, and the style declaration area is responsible for controlling the visual presentation.

[0095] Specifically, this direct push process completely eliminates redundant intermediate domain conversions. Specific technical relationships are established between different regions of the code through internal compilation dependencies, which greatly reduces parsing latency and lowers the computational power consumption during the conversion stage.

[0096] Specifically, the abstract syntax tree is assembled in the order of template nodes, script nodes, and style nodes. Each node carries a corresponding syntax feature tag to ensure accurate matching of each area of ​​the single-file component during destructuring. When generating the template structure area, the spatial arrangement of component instance nodes, slot placeholders, event listener directives, etc., are converted into template syntax that conforms to the Vue specification. At the same time, the class, style, and other attributes of the nodes are standardized, and the style attributes in the design draft are converted into the binding format supported by the Vue template. When generating the script logic area, reactive state variables, event callback functions, and component communication APIs are integrated. The code for PI, attribute interface declarations, and other content is organized in the order of import instructions, state definitions, method definitions, and export declarations to ensure the standardization and maintainability of the script logic. When the style declaration area is generated, the style information in the design draft is extracted, converted into CSS style code, and the scoped attribute is added to isolate the style scope. At the same time, the fixed style values ​​in the design draft are mapped to the theme variables of the visual system to improve the reusability and maintainability of the styles. In addition, the code is syntax-checked during the code generation process. If a syntax error is detected, it is automatically corrected and the correction location is marked to ensure that the generated code can be directly compiled and run.

[0097] In some embodiments, after generating the view framework code in single-file component format, the method further includes deep code refactoring optimization: performing dependency graph analysis on all state variables and method bodies in the script logic region; identifying clusters of variables and methods that reference each other in the dependency graph; if the call frequency of a cluster exceeds a preset threshold and has a complete data loop, then the cluster is removed from the script logic region; the removed cluster is encapsulated into an independent composite logic function, and a dependency import instruction pointing to the composite logic function is inserted in the script logic region.

[0098] Specifically, dependency graph analysis constructs a directed data flow graph to track the read and write boundaries of variables. This effectively prevents the accumulation of bar-like code under large-scale components and achieves lightweight and high availability of the underlying runtime infrastructure by physically cutting the scope.

[0099] Example 2, refer to Figure 2 As shown, a Vue component code auto-generation system based on Figma design drafts includes:

[0100] The design draft node recognition module obtains the design draft node tree and identifies the component definition nodes and component instance nodes associated with the component definition nodes in the design draft node tree.

[0101] The variant attribute and interaction link extraction module extracts the variant attribute set of the component definition node, and extracts the prototype interaction links for each variant attribute in the variant attribute set;

[0102] The state and communication logic construction module constructs state response mapping logic based on the variant attribute set, and constructs component communication events associated with the state response mapping logic according to the prototype interaction link;

[0103] The content distribution slot generation module performs spatial nesting relationship traversal on the design draft node tree and identifies the content variation characteristics of the component instance nodes to generate a content distribution slot structure.

[0104] The Vue single-file component code generation module directly generates view framework code in single-file component format based on the state response mapping logic, the component communication events, and the content distribution slot structure. The view framework code includes mutually isolated template structure areas, script logic areas, and style declaration areas.

[0105] In summary, this invention breaks the inherent coupling contradiction of losing framework-specific capabilities due to excessive abstraction in the general description layer. By extracting node variants to establish a reactive spatial mapping, comparing instance topology offsets to generate dynamic distribution slots, and extracting independent logical functions based on the call dependency graph, this solution directly completes the deep customized semantic reconstruction of the target view framework at the memory parsing end. This not only ensures high-fidelity synchronization between the rendering result and the source file, but also eliminates the risk of logical discontinuity caused by complex interactions from the underlying physical mechanism, significantly improving the stability and execution efficiency of the target code at the underlying system runtime.

[0106] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.

Map the style identifier to the vision system configuration dictionary to obtain the corresponding theme variable code; A style block with a scope isolation identifier is generated in the style declaration area, and the hard-coded style values ​​are replaced with the theme variable code within the style block.

7. The method for automatically generating Vue component code based on Figma design drafts according to claim 1, characterized in that, After generating the view framework code in single-file component format, the following is also included: Perform dependency graph analysis on all state variables and method bodies in the script logic region; Identify clusters of mutually referencing variables and methods in the dependency graph. If the call frequency of the cluster exceeds a preset threshold and has a complete data loop, then the cluster is removed from the script logic area. The extracted cluster is encapsulated as an independent composite logic function, and a dependency import instruction pointing to the composite logic function is inserted in the script logic area.

8. The method for automatically generating Vue component code based on Figma design drafts according to claim 1, characterized in that, The state response mapping logic includes one-way data binding logic and two-way data binding logic; the process of constructing the two-way data binding logic includes: Identify whether the component instance node has a preset form interaction feature type; If the form interaction feature type is present, a two-way reactive state variable bound to the target input value is automatically constructed, and a two-way binding instruction stream is generated in the template structure area.

9. The method for automatically generating Vue component code based on Figma design drafts according to claim 1, characterized in that, The content distribution slot structure also includes: If the content variation features are identified to cover iterative operations on the underlying dynamic dataset, then the data source variables on which the iterative operations depend are extracted. Generate a scope slot structure and attach the data source variable as an exposed parameter to the property set of the scope slot structure.

10. A Vue component code automatic generation system based on Figma design drafts, used to implement the Vue component code automatic generation method based on Figma design drafts as described in any one of claims 1-9, characterized in that, include: The design draft node recognition module obtains the design draft node tree and identifies the component definition nodes and component instance nodes associated with the component definition nodes in the design draft node tree. The variant attribute and interaction link extraction module extracts the variant attribute set of the component definition node, and extracts the prototype interaction links for each variant attribute in the variant attribute set; The state and communication logic construction module constructs state response mapping logic based on the variant attribute set, and constructs component communication events associated with the state response mapping logic according to the prototype interaction link; The content distribution slot generation module performs spatial nesting relationship traversal on the design draft node tree and identifies the content variation characteristics of the component instance nodes to generate a content distribution slot structure. The component matching module, based on the preset design system configuration, matches the component instance nodes with the target visual component library and filters out suitable standard components; The Vue single-file component code generation module directly generates view framework code in single-file component format based on the state response mapping logic, the component communication events, the content distribution slot structure, and the matched standard components. The view framework code includes mutually isolated template structure areas, script logic areas, and style declaration areas.
