mini-rspackA simplified Rspack bundler using Rust

What is mini-rspack? ​

mini-rspack is a simplified implementation of Rspack bundler using Rust and Node.js bindings. It demonstrates how to create a JavaScript bundler with Rust for improved performance. This project serves as an educational resource for understanding modern bundler architecture and the internals of tools like webpack and rspack.

Quick Start ​

# Clone the repository
git clone https://github.com/Sunny-117/mini-rspack.git
cd mini-rspack

# Install dependencies
npm install

# Build the Rust code
npm run build

# Create a configuration file
const { createCompiler } = require('mini-rspack');
const compiler = createCompiler(options);

# Run the compiler
compiler.run((err, stats) => {
  console.log('Compilation successful!');
});

Features ​

• Webpack-compatible API: Familiar interface for webpack users
• Support for CommonJS and ES modules: Handle both module formats
• Entry point processing: Support for multiple entry points
• Module resolution: Resolve dependencies between modules with custom resolver
• Plugin system with hooks: Extend functionality with plugins (similar to Tapable)
• Loader system: Transform module content with loaders
• Watch mode: Automatically rebuild when files change
• Comprehensive test suite: Tests in both Rust and JavaScript

Technical Implementation ​

• Rust Core: Core bundling logic implemented in Rust for performance
• napi-rs: Node.js native modules from Rust code with proper bindings
• Module Parsing: Regex and basic AST analysis to extract dependencies
• Dependency Resolution: Path resolution similar to Node.js module resolution
• Code Generation: JavaScript bundle with proper module wrapping and runtime
• Hook System: Hook-based plugin system similar to webpack's Tapable
