Description

[0001] This invention belongs to the field of low-code development and mini-program technology, specifically involving a low-code page configuration system for mini-programs that supports module drag-and-drop. Background Technology

[0002] With the increasing popularity of WeChat Mini Programs, the demand for them from various enterprises and individuals is growing daily. However, the high barriers to entry, long development cycles, and high costs associated with Mini Program development are becoming increasingly prominent. Low-code development technology, as a development model of "visual drag-and-drop + minimal code addition," effectively lowers the development threshold and shortens the development cycle, becoming the mainstream trend in Mini Program development. Currently, some low-code configuration systems for Mini Programs that support module drag-and-drop have emerged in the market, but in practical applications, many technical pain points still exist, making it difficult to meet the needs of different users. These are as follows: Poor drag-and-drop flexibility and unpleasant interactive experience: The existing system's drag-and-drop function is relatively simple, mostly using a single drag-and-drop mode, lacking auxiliary functions such as magnetic alignment and grid snapping. During the drag-and-drop process, module overlap and positional deviation are prone to occur, and the drag-and-drop response latency is high, resulting in sluggish operation. At the same time, it does not support cross-module linkage drag-and-drop, and the modules are independent of each other, making it impossible to implement complex interactive logic configurations.

[0003] Insufficient module adaptability and poor reusability: The existing system's module library is limited in variety, mainly consisting of basic UI components, lacking targeted business function modules, and cannot meet the needs of specific scenarios such as e-commerce and government affairs; moreover, the modules are not standardized and encapsulated, resulting in poor compatibility between different modules, and custom modules cannot be dragged and dropped normally after being uploaded, leading to low module reusability.

[0004] Redundant code generation and poor performance: Existing systems generate a large number of redundant components, invalid code and default configurations in the mini-program code, resulting in large code size, slow page loading speed and affecting user experience; at the same time, the code generation format is uniform and cannot adapt to different development needs (such as native mini-programs, uni-app), which is not flexible enough.

[0005] Multi-platform adaptation is difficult and displays inconsistently: The existing system lacks an effective multi-platform adaptation mechanism. The configured mini-program pages display inconsistently on mobile phone screens and tablet devices of different sizes, requiring manual adjustment of layout and size, which increases the operation cost; in addition, the preview and debugging function is imperfect and cannot provide real-time feedback on the display effect of different terminals, resulting in low debugging efficiency.

[0006] The existing system has a high learning curve for non-technical personnel and poor collaboration: the user interface is complex and the attribute configuration process is cumbersome, making it difficult for non-technical personnel to get started quickly; at the same time, it does not support multi-user collaborative configuration, and when multiple people are developing together, they need to frequently synchronize configuration files, which can easily lead to configuration conflicts and affect development efficiency.

[0007] In addition, there are some related low-code configuration solutions in the existing technology. For example, the invention patent "Low-Code Drag-and-Drop Development System for WeChat Mini Programs" with publication number CN 115270238B only implements basic module drag-and-drop functions, without designing cross-module linkage mechanisms and on-demand code generation strategies, resulting in serious code redundancy and poor multi-terminal adaptation. The research "Low-Code Drag-and-Drop System for WeChat Mini Programs" with publication number arXiv:2512.01234v1 proposes a low-code drag-and-drop solution for mini programs, but its module adaptability is insufficient and it does not support custom module uploads and multi-user collaborative configuration. The research "Visual Configuration System for MiniProgram Pages" with publication number unpatentable.org proposes a visual configuration solution for mini program pages, but its drag-and-drop flexibility is poor, the interactive experience is not good, and it cannot meet the configuration needs of complex scenarios.

[0008] In summary, existing low-code configuration systems for mini-programs that support drag-and-drop functionality suffer from several technical pain points, including poor drag-and-drop flexibility, insufficient module adaptability, code redundancy, difficulties in multi-platform adaptation, high operational barriers for non-technical personnel, and poor collaboration. These shortcomings fail to meet the development needs of mini-programs across different scenarios and for different users. Therefore, developing a low-code page configuration system for mini-programs that supports drag-and-drop functionality, offers high drag-and-drop flexibility, strong module adaptability, lightweight code generation, efficient multi-platform adaptation, and a low operational barrier has become a pressing technical challenge in the current low-code development and mini-program technology field. Summary of the Invention

[0009] To address the aforementioned shortcomings in existing technologies, the present invention aims to provide a low-code page configuration system for mini-programs that supports drag-and-drop functionality. This system solves problems such as poor drag-and-drop flexibility, insufficient module adaptability, weak cross-module linkage capabilities, code redundancy, difficulties in multi-platform adaptation, high operational barriers for non-technical personnel, and poor collaboration in existing systems. It enables visualized, efficient, and lightweight configuration of mini-program pages, lowers the development threshold for mini-programs, improves development efficiency, adapts to various scenarios such as e-commerce, government affairs, and enterprise display, and meets the different needs of non-technical personnel and professional developers.

[0010] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A low-code page configuration system for mini-programs that supports module drag-and-drop includes a drag-and-drop interaction layer, a module management layer, a configuration parsing layer, a code generation layer, and a preview and debugging layer. These layers work together to enable visual drag-and-drop configuration of mini-program pages. The system specifically includes the following core modules and workflows: The module management layer stores various commonly used functional modules of mini programs, establishes a module category index, supports custom uploading, editing and deletion of modules, and standardizes the encapsulation of modules to ensure that modules are drag-and-drop and reusable; The drag-and-drop interaction layer provides a visual drag-and-drop interface, integrates an intelligent drag-and-drop engine, and supports users to drag, scale, rotate, stitch, and set cross-module linkage for modules in the module management layer, providing real-time feedback on drag-and-drop operation results; The configuration parsing layer receives operation instructions from the drag-and-drop interaction layer, parses the position, size, attributes, and linkage relationships of the modules, generates standardized configuration files, and performs legality checks on the configuration information to avoid configuration errors. The code generation layer reads the standardized configuration file output by the configuration parsing layer, adopts an on-demand code generation strategy, automatically generates lightweight executable code for mini-programs, eliminates redundant code, and ensures that the code can be directly deployed and run. The preview and debugging layer receives the mini-program code output from the code generation layer, providing real-time preview, multi-terminal adaptation preview, and debugging functions. It allows users to modify and verify the configuration page until their needs are met.

[0011] The technical solution of the present invention will be described in detail below: (I) Overall System Architecture Design This invention adopts a five-layer architecture: drag-and-drop interaction layer, module management layer, configuration parsing layer, code generation layer, and preview / debugging layer. Each layer is independent yet collaborative, balancing operational flexibility, module adaptability, lightweight code, and ease of debugging. The specific architecture design is as follows: 1. Drag-and-Drop Interaction Layer: As the core entry point for user operations, it provides a simple and intuitive visual drag-and-drop interface, mainly including the drag-and-drop operation area, attribute configuration panel, module list area, and operation toolbar. The drag-and-drop operation area displays the mini-program page canvas, where users can drag, scale, rotate, and merge modules; the attribute configuration panel displays the configurable attributes of the currently selected module, supporting user customization; the module list area displays all modules in the module management layer, arranged by category index for easy user searching; the operation toolbar provides commonly used operations such as undo, redo, save, preview, and export, improving user operation efficiency.

[0012] 2. Module Management Layer: As the core of the system's modules, it is responsible for the storage, management, encapsulation, and updating of the mini-program's functional modules. It mainly includes a module library, a module encapsulation module, a module management module, and a category index module. The module library stores three types of modules: basic component modules, business function modules, and custom modules, covering commonly used UI and business components in mini-program development. The module encapsulation module standardizes the encapsulation of all modules, unifying module interfaces, attribute specifications, and drag-and-drop protocols to ensure strong compatibility, drag-and-drop functionality, and reusability between different modules. The module management module supports users in uploading, editing, deleting, enabling / disabling, and other operations on modules. Custom modules, after being uploaded, are processed by the encapsulation module and included in the module library. The category index module categorizes and indexes the modules in the module library, classifying them by module type, application scenario, and functional purpose, facilitating quick searching and retrieval by users.

[0013] 3. Configuration Parsing Layer: As the core intermediary layer of the system, it is responsible for connecting the drag-and-drop interaction layer and the code generation layer. It mainly includes an instruction parsing module, a configuration file generation module, and a validity verification module. The instruction parsing module receives user operation instructions from the drag-and-drop interaction layer (such as dragging, attribute modification, and linkage settings), and parses out core data such as the module's position coordinates, size parameters, attribute information, and linkage relationships. The configuration file generation module organizes the parsed core data and generates a standardized JSON configuration file to ensure the standardization and universality of the configuration information. The validity verification module verifies the configuration file, including module compatibility verification (checking whether different modules are compatible), attribute parameter validity verification (checking whether attribute values ​​conform to specifications), and linkage logic rationality verification (checking whether linkage relationships are reasonable). If the verification fails, it outputs specific error messages and modification suggestions to avoid configuration errors causing code generation failure.

[0014] 4. Code Generation Layer: This layer is responsible for converting standardized configuration files into directly deployable and runnable mini-program code. It mainly includes a code generation module, a code optimization module, and a code format conversion module. The code generation module uses an on-demand code generation strategy based on the configuration file, generating only the module code, attribute configuration code, and linkage logic code required for the page, while eliminating unused redundant components, invalid code, and default redundant configurations. The code optimization module compresses and obfuscates the generated code to reduce its size and improve the mini-program's page loading speed. The code format conversion module supports converting the generated code into both WeChat mini-program native code and uni-app code formats to adapt to different development needs and deployment environments.

[0015] 5. Preview and Debug Layer: Responsible for previewing and debugging the mini-program pages, ensuring the configuration pages meet requirements. This mainly includes a preview module, a debug module, and a version management module. The preview module supports three modes: WeChat Developer Tools preview, WeChat QR code preview, and webpage simulation preview, providing real-time feedback on the display effect and interaction logic of the configuration page. The debug module supports code syntax validation, page layout debugging, interaction logic debugging, and API integration testing. Users can modify configurations and view debugging results in real time. The version management module retains the user's historical configuration versions, allowing users to roll back to previous configurations at any time, preventing irreversible configuration errors.

[0016] In addition, the system has added a multi-terminal adaptation module, a data management module, and a collaborative configuration module to further enhance the system's usability and flexibility. Multi-platform adaptation module: Integrates mini-program terminal adaptation algorithm, automatically identifies the screen size and resolution of different terminals (mobile phone, tablet, WeChat developer tools), adjusts the module layout, size and display effect, and ensures that the configuration page is displayed consistently and the interaction is smooth on different terminals without the need to manually adjust the adaptation parameters; Data Management Module: Supports users to bind the backend data interface of the mini-program, realizing the linkage between the configuration page and the backend data, including data query, data submission, data display and other functions; it also supports local data caching, automatically saving configuration information during the user configuration process to avoid configuration data loss, and supports exporting and importing configuration files for easy data migration; Collaborative configuration module: Supports multi-user collaborative configuration, allowing different users to simultaneously drag and drop configurations on the same mini-program page, synchronizing configuration operations in real time to avoid configuration conflicts; supports hierarchical permission management, distinguishing between administrator, editor, and viewer permissions, with administrators able to assign operation permissions to ensure configuration security.

[0017] (II) Detailed Design of Core Functional Modules 1. Intelligent drag-and-drop engine design The intelligent drag-and-drop engine is the core of enhancing drag-and-drop flexibility and interactive experience. It adopts a dual mode of magnetic alignment and grid snapping, combined with functions such as collision detection and trajectory memory. The specific design is as follows: Dual-mode drag-and-drop assistance: The magnetic alignment mode allows modules to automatically snap and align when dragged close to other modules (alignment accuracy ≤ 1px), preventing module misalignment; the grid snap-in mode allows users to set the grid spacing (adjustable from 10px to 50px), and modules automatically snap to grid nodes during dragging, ensuring a neat page layout; users can freely switch between the two modes as needed, or turn off the assistance mode.

[0018] Collision detection and boundary restrictions: During dragging, the system detects collisions between the current module and other modules or page boundaries in real time. If module overlap or exceeds the page boundary is detected, a visual prompt is given immediately, and dragging operations are restricted to avoid module overlap and layout chaos. At the same time, it supports module layer adjustment, allowing users to move the module layer up and down to achieve module overlay display.

[0019] Drag trajectory memory and operation undo: Records every drag operation of the user, supports undo and redo operations, making it easy for users to correct operation errors; drag response latency ≤100ms, ensuring smooth drag operation without lag.

[0020] Cross-module linkage settings: Users can configure linkage relationships between modules, including trigger conditions and associated actions. For example, users can configure the "click button module" to trigger the display of the "form module", and the "input box module" to trigger data refresh of the "list module" after entering content; the linkage logic supports visual configuration, and users can complete the linkage configuration and realize complex interaction logic without writing code, through drop-down selection and parameter settings.

[0021] 2. Module Management and Standardized Packaging The core of the module management layer is to achieve module diversification, standardization, and reusability, and the specific design is as follows: Module Classification and Storage: The module library is divided into three categories, covering all scenarios of mini-program development: Basic component module: Includes basic UI components such as buttons, input boxes, images, text, lists, dropdown lists, checkboxes, and radio buttons, and supports basic attribute configuration (size, color, font, etc.). Business function modules: including commonly used business components of mini programs such as product display, form submission, payment interface, map positioning, message push, login and registration, and data statistics. They have built-in standardized business logic, which users can directly drag and drop to use without additional configuration. Custom modules: Support users to upload their own component code (such as Vue components, native mini-program components), which are then standardized through module encapsulation (unified interface, attribute specifications) and incorporated into the module library, enabling drag-and-drop use and reuse of custom modules.

[0022] Standardized module encapsulation: A unified module encapsulation protocol is adopted to encapsulate all modules, defining unified module interfaces, attribute fields, and event triggering mechanisms to ensure strong compatibility between different modules; the encapsulated modules contain the core parameters required for dragging (such as size, position, draggable indicators, etc.), support dragging, scaling, rotation and other operations, while retaining the module's own functional characteristics.

[0023] Module management functions: Supports users to upload, edit, delete, enable / disable, etc. of modules; when editing a module, users can modify the module's default attribute values, display name, category, and other information; after disabling a module, the module will not be displayed in the module list area, but it will not affect the use of the configured page; supports batch operations on modules to improve management efficiency.

[0024] 3. On-demand code generation and optimization To address the issues of code redundancy and poor performance in existing systems, this invention designs an on-demand code generation strategy, as follows: On-demand generation logic: The code generation module reads the standardized configuration file, analyzes the modules, attributes and linkage logic required by the page, and generates only the code necessary for the current page, eliminating unused redundant components, invalid code and default redundant configurations (such as unused styles, invalid event bindings, etc.); for example, if the page does not use the payment interface module, payment-related code will not be generated, effectively reducing the code size.

[0025] Code optimization: The code optimization module compresses and obfuscates the generated code, removes comments and spaces, compresses CSS and JS code, and reduces code size; at the same time, it optimizes the code syntax to improve code execution efficiency and ensure that the page loading speed of the mini program is improved by more than 30%.

[0026] Multi-format support: The code format conversion module supports converting the generated code into two formats: WeChat Mini Program native code and uni-app code. Users can choose the corresponding format according to their own development needs. Native code can be directly deployed and run in WeChat Developer Tools, while uni-app code can be compiled into multi-platform Mini Programs, improving the system's flexibility.

[0027] 4. Multi-platform adaptation and preview debugging Multi-platform adaptation and preview debugging are key to ensuring that the configuration page meets the requirements. The specific design is as follows: Multi-platform adaptation mechanism: The multi-platform adaptation module integrates a terminal recognition algorithm to automatically identify the screen size and resolution of the current preview terminal. It adopts an adaptive layout algorithm to adjust parameters such as the position, size, and font size of the module to ensure that the configuration page displays consistently and interacts smoothly on mobile phones, tablets, and WeChat developer tools of different sizes. The adaptation process is completed automatically without the need for manual adjustment by the user.

[0028] Multi-mode preview: Supports three preview modes to meet the preview needs of different scenarios: WeChat Developer Tools Preview: Generate a preview QR code. Users can scan the code in WeChat Developer Tools to preview the page and view the detailed effects and code execution. Mobile WeChat QR code preview: Generates a WeChat QR code, which users can scan with their mobile WeChat app to preview the page and intuitively view the display effect and interaction logic on the mobile device; Webpage simulation preview: A webpage simulation preview window is provided in the system interface to display the effect of the configuration page in real time. It supports scaling to simulate different mobile phone sizes, making it convenient for users to view quickly.

[0029] Comprehensive debugging: The debugging module supports code syntax verification, page layout debugging, interaction logic debugging, and API integration testing. Code syntax validation: Real-time validation of syntax errors in generated code, outputting error messages and suggested modifications; Page layout debugging: Supports viewing the position coordinates and size parameters of modules, modifying configurations in real time, and providing real-time feedback on layout changes; Interaction logic debugging: Simulate user operations to verify whether the module linkage logic and interaction events are normal; Interface integration testing: Supports binding test interfaces to verify whether the interaction between the page and the backend data is normal, and ensures that the data query and submission functions are normal. Attached image description: Figure 1 This is a flowchart of the low-code page configuration system for mini-programs that supports module dragging in this embodiment. Detailed Implementation

[0030] The technical solution of the present invention will be further described in detail below with reference to three specific embodiments. These embodiments are only for explaining the present invention and are not intended to limit the scope of protection of the present invention. Each embodiment verifies the drag-and-drop flexibility, module adaptability, code generation efficiency, and multi-terminal adaptation effect of the system of the present invention, ensuring the practicality and innovation of the system.

[0031] Example 1: E-commerce Mini Program Page Configuration Scenario This embodiment applies to the configuration scenario of the homepage and product details page of an e-commerce mini-program. The users are non-technical personnel, and the requirement is to quickly configure an e-commerce page that includes modules such as product display, search box, category navigation, shopping cart, and order button. The requirements include flexible drag-and-drop functionality, smooth module interaction, and direct code deployment. The specific implementation process is as follows: 1. System Setup: Launch the WeChat Mini Program low-code page configuration system that supports module drag-and-drop functionality, and enter the visual drag-and-drop interface. The module management layer has loaded a dedicated e-commerce module library, including over 20 e-commerce-specific business modules such as product display, search box, category navigation, shopping cart, order button, and carousel. The drag-and-drop interaction layer enables magnetic alignment and grid snapping dual modes, with the grid spacing set to 20px. The code generation layer generates native WeChat Mini Program code by default, and the multi-platform adaptation module enables automatic adaptation mode.

[0032] 2. Module Drag and Drop & Layout: E-commerce operators can locate the required modules in the module list area, drag the carousel module to the top of the page, and adjust the carousel size using scaling; drag the search box module below the carousel, aligning it with the carousel's magnetic tags; drag the category navigation module below the search box, setting it to a 4-column layout; drag the product display module below the category navigation, setting it to a 2-column layout, and selecting a product card style; drag the shopping cart module and the order button module to the bottom of the page, aligning them with the page boundaries. During the dragging process, the system performs real-time collision detection to avoid module overlap, with a drag response latency of ≤80ms, ensuring smooth and lag-free operation.

[0033] 3. Attribute Configuration and Linkage Settings: Select the carousel module, the attribute configuration panel displays the carousel attributes, modify the carousel switching time to 3 seconds, and upload 3 product promotional images; select the search box module, set the search suggestion text to "Search for products", and bind the product search interface; select the category navigation module, modify the category name, and upload category icons; select the product display module, bind the product list interface, and set the product card display fields; select the order button module, configure the linkage logic: clicking the order button triggers the display of the shopping cart module, and simultaneously pops up an order confirmation pop-up window.

[0034] 4. Configuration parsing and validity verification: After configuration, the configuration parsing layer receives operation instructions, parses the position, size, attributes and linkage relationships of the modules, and generates a standardized JSON configuration file; the validity verification module verifies the configuration file to confirm that the modules have good compatibility, the attribute parameters are valid, the linkage logic is reasonable, and the verification passes.

[0035] 5. Code Generation and Optimization: The code generation layer reads the standardized configuration file and adopts an on-demand code generation strategy, generating only the module code, attribute configuration code, and linkage logic code required for the current page, and eliminating unused redundant code; the code optimization module compresses and optimizes the generated code, reducing the code size by 40%; and generates native WeChat Mini Program code that can be directly deployed and run.

[0036] 6. Preview Debugging and Multi-Platform Adaptation: The preview debugging layer provides three preview modes. E-commerce operators can scan the QR code with their mobile WeChat to preview the page and check its display effect on mobile devices. If the size of the product display module is slightly off, they can return to the drag interface to adjust the size and synchronize the preview effect in real time. The multi-platform adaptation module automatically adapts to different sized mobile phones, and the display effect is consistent on 4.7-inch and 6.7-inch mobile phones. The debugging module verifies that the code syntax is correct, the interface integration is normal, and the linkage logic is smooth.

[0037] 7. Deployment and Execution: After the code is generated and debugged without errors, the e-commerce operations team exports the mini-program code, uploads and reviews it in the WeChat Developer Tools, and deploys it after the review is approved.

[0038] Implementation Results: Non-technical personnel (e-commerce operations) completed the configuration of the e-commerce mini-program homepage and product detail page in just 25 minutes. The drag-and-drop functionality was flexible and easy to use, with a drag-and-drop response latency of ≤80ms. The generated code was lightweight, improving page loading speed by 35%. Multi-platform adaptation was excellent, with consistent display across different terminals. Module linkage was smooth, meeting the business needs of e-commerce scenarios. The code could be directly deployed and run, improving development efficiency by over 65% and effectively reducing the development threshold and cost of e-commerce mini-programs.

[0039] Example 2: Configuration Scenario for Government Service Mini Program Page This embodiment applies to the configuration scenario of the "Personal Matters Processing" page in the government service mini-program. The user is a government employee, and the requirement is to configure a government page that includes modules such as form submission, identity verification, matter description, and progress query. The form module is required to be highly adaptable, display consistently across multiple platforms, and have normal data linkage. The specific implementation process is as follows: 1. System Setup: Launch the system of this invention and enter the drag-and-drop interface. The module management layer loads a dedicated module library for government scenarios, including 15+ dedicated government modules such as form submission, identity verification, text description, progress query, button, and upload. The drag-and-drop interaction layer enables magnetic alignment mode and disables grid snapping. The code generation layer selects to generate native WeChat mini-program code, and the multi-terminal adaptation module enables automatic adaptation mode, focusing on adapting to mobile phones and tablet terminals.

[0040] 2. Module Drag and Drop and Layout: Government staff can drag the identity verification module to the top of the page and center it; drag the text description module below the identity verification module to display instructions for handling the matter; drag the form submission module below the text description module, the form includes fields such as name, ID number, contact number, matter type, and uploaded materials; drag the progress query module and submit button module below the form and center them; during the dragging process, the system performs real-time collision detection to avoid module overlap, and the drag response latency is ≤90ms.

[0041] 3. Attribute Configuration and Data Linkage: Select the identity verification module, configure the verification method, and bind the government identity verification interface; select the text description module, modify the description content, set the font size and color, and adjust the line spacing; select the form submission module, edit the form fields, set required fields and input format validation, bind the form submission interface, and configure a "Submission Successful" prompt to be triggered upon successful submission; select the progress query module, bind the progress query interface, and set the query conditions; select the submit button module, and configure the linkage logic: when the submit button is clicked, first verify the completeness of the form, and after successful verification, submit the form data and simultaneously trigger a refresh of the progress query module.

[0042] 4. Configuration parsing and validity verification: After configuration, the configuration parsing layer generates a standardized configuration file. The validity verification module verifies the form field validation rules, interface binding, and linkage logic. If it finds that the form field "ID number" does not have a format validation set, it outputs an error message. After the government staff modifies the configuration, the verification passes.

[0043] 5. Code Generation and Optimization: The code generation layer adopts an on-demand code generation strategy to generate core code such as form submission, identity verification, and progress query, while eliminating redundant code. After code optimization, the code size is reduced by 38%, and the page loading speed is improved by 32%. Native WeChat Mini Program code is generated, supporting direct deployment.

[0044] 6. Preview, Debugging, and Multi-Platform Adaptation: View the page display effect through three modes: WeChat Developer Tools preview, mobile phone QR code preview, and tablet preview; the multi-platform adaptation module automatically adjusts the page layout to ensure consistent display on mobile phones and tablets, and form fields adapt to different screen sizes without misalignment or obstruction; the debugging module verifies that the form validation logic is normal (provides prompts when required fields are not filled or the format is incorrect), the interface integration is normal, data can be uploaded normally after the form is submitted, and the progress query function is normal.

[0045] 7. Deployment and Operation: Export the code, upload and review it in WeChat Developer Tools, and deploy it online after approval so that the public can handle personal matters.

[0046] Implementation Results: Government staff completed the configuration of the government service mini-program page in just 30 minutes.

Data linkage is normal, and the form submission and progress query functions are stable. The code is lightweight, and the page loads smoothly, meeting the needs of government service scenarios. This effectively improves the development efficiency of government mini-programs and reduces development costs.

[0047] Example 3: Configuration Scenario for Enterprise Display Mini Program Page This embodiment applies to a scenario where a business showcase mini-program page is configured. The user is a business team, and the requirement is to configure a business showcase page that includes modules such as company profile, product display, contact information, and news updates. It also requires uploading the company's own custom modules and supports collaborative configuration by multiple users. The specific implementation process is as follows: 1. System Setup and Permission Allocation: Upon starting the system of this invention, the administrator creates a configuration project for the enterprise display mini-program and assigns permissions: the administrator has full operation permissions, the editor has drag-and-drop, attribute configuration, and preview permissions, and the viewer only has preview permissions; the module management layer loads the basic component module and the enterprise display-specific module, and also supports the upload of custom modules.

[0048] 2. Custom Module Upload and Packaging: Administrators upload custom modules (company logo component, product carousel component), and the module packaging module standardizes and encapsulates the custom modules, unifying interface and attribute specifications, and includes them in the module library, supporting drag-and-drop usage; administrators can edit the default attribute values ​​of custom modules, setting the default size of the company logo component and the default switching time of the product carousel component.

[0049] 3. Multi-user collaborative drag-and-drop configuration: Three users can log in to the system simultaneously and collaboratively configure the settings page. Administrator: Responsible for the overall layout planning of the page, dragging the company logo component to the top of the page, setting it to center, and modifying the logo image; dragging the company introduction module below the logo and editing the introduction content; Editor: Responsible for configuring the product display and news feed modules; dragging and dropping the product carousel component and product list module below the company profile, binding the product data interface, and setting the product display style; dragging the news feed module below the product display module and editing the news content; Viewers: Can view configuration progress and page effects in real time, and offer suggestions for modification; they do not have operational permissions.

[0050] During collaborative configuration, the system synchronizes the operations of each user in real time to avoid configuration conflicts. The drag-and-drop response latency is ≤100ms, ensuring smooth operation.

[0051] 4. Attribute Configuration and Linkage Settings: The editor selects the Contact Information module, drags it to the bottom of the page, and sets information such as contact phone number, address, and WeChat official account; configure linkage logic: clicking on the news title in the News Dynamics module triggers the display of the news details pop-up window; clicking on a product in the Product List module triggers a jump to the product details page (the jump page can be configured synchronously through this system).

[0052] 5. Configuration parsing and validity verification: After configuration, the configuration parsing layer generates a standardized configuration file. The validity verification module verifies the compatibility and linkage logic between the custom module and the system module. If the verification passes, no error message is displayed.

[0053] 6. Code Generation and Optimization: The code generation layer adopts an on-demand code generation strategy, generating all core code, including custom modules, and eliminating redundant code; after code optimization, the code size is reduced by 42%; administrators can choose to generate uni-app code, which can be compiled into WeChat, Alipay and other multi-platform mini programs.

[0054] 7. Preview, Debug, and Deployment: The preview and debugging layer allows for multi-mode previewing to check the page display effects and interaction logic. After debugging and confirming that there are no errors, the administrator exports the uni-app code, compiles it into a multi-platform mini-program, and deploys it online.

[0055] Implementation Results: Three users collaborated to configure the enterprise showcase mini-program page in just 40 minutes. Custom modules were easy to upload and encapsulate, and could be dragged and dropped for normal use. Collaborative configuration was smooth with no configuration conflicts. The generated uni-app code is compatible with multiple mini-program platforms, is lightweight, and improves page loading speed by 36%.
