Vue2 to Vue3 Migration Tool

Overview

This tool is designed to assist in the migration process from Vue2 to Vue3 by automatically converting Vue2 component syntax to Vue3 composition API syntax. It aims to speed up the migration process by handling many of the repetitive conversion tasks.

Current State

This tool is currently a work in progress. While it can handle many common conversion scenarios, it may not cover all edge cases and might occasionally produce output that requires manual adjustment.

Features

• Converts Vue2 component syntax to Vue3 composition API syntax
• Handles conversion of data, computed properties, methods, and lifecycle hooks
• Manages imports and Vuex integration
• Preserves existing logic while updating to Vue3 patterns

Limitations

• Does not add the <script setup> tag; uses the standard <script> tag instead
• Retains the return statement in the setup function rather than using top-level variables
• Will miss semicolons or make other minor syntax errors
• Complex or nested structures might require manual review and adjustment
• It will have issues with lines that use regex
• Review the input.txt and output.txt files for current limitation

Usage

1. Place your Vue2 component code in the input.txt file.
2. Run the main script:

   python main.py
   

3. The converted Vue3 code will be output to output.txt.
4. Review the output and make any necessary manual adjustments.

Project Structure

• main.py: The entry point of the application
• parser.py: Contains the Vue2Scanner class for parsing Vue2 components
• generator.py: Contains the Vue3Generator class for generating Vue3 syntax
• Vue2Component.py: Defines the structure for storing component information
