This PR implements foundational JavaScript processing functionality using the SWC ecosystem and integrates it with Actix-Web for server-side rendering capabilities.

🚀 Features Implemented

✅ JavaScript/TypeScript Parsing

Parser Implementation: Created JavaScriptParser using swc_ecma_parser with ES2022 support
TypeScript Support: Full TypeScript parsing with interfaces, decorators, and modern syntax
AST Generation: Converts JavaScript/TypeScript code to Abstract Syntax Trees

let parser = JavaScriptParser::new();
let ast = parser.parse_code(js_code, Some("example.js"))?;
// ✅ Supports JavaScript, TypeScript, and JSX/TSX files

✅ React Component Compilation

JSX/TSX Compilation: Implemented ReactCompiler using swc_ecma_react_compiler
React Transform: Converts JSX syntax to React.createElement calls
TypeScript Integration: Supports React components with TypeScript interfaces

let compiler = ReactCompiler::new();
let compiled = compiler.compile_react_component(tsx_code, Some("component.tsx"))?;
// Input:  <h1>{title}</h1>
// Output: React.createElement("h1", null, title)

✅ SSR Integration with ssr_rs

HTTP Request Abstraction: Created SimpleHttpRequest trait for SSR processing
V8 Integration: Optional server-side rendering using ssr_rs crate
Request Processing: StringHttpRequest implementation with header extraction

✅ Actix-Web Server Integration

Route Handlers: Basic endpoints for JavaScript processing and React rendering
HTTP Server: Configurable Actix-Web server on localhost:8080
Request Processing: Extract and process HTTP request information

// GET / - Basic JavaScript processing endpoint
// GET /react - React component rendering endpoint  
// GET /js/* - JavaScript file processing

🏗️ Architecture

Conditional Compilation

Feature Gates: ssr feature for V8-dependent functionality
Modular Design: Core parsing works without heavy V8 dependencies
Testing: Comprehensive test suite for all components

Dependencies Added

[dependencies]
swc = "25.0.0"
swc_common = "11.1.3" 
swc_ecma_parser = "14.0.2"
swc_ecma_ast = "11.0.0"
swc_ecma_react_compiler = "4.0.2"
actix-web = "4.9"
ssr_rs = { version = "0.8.3", optional = true }

[features]
default = ["ssr"]
ssr = ["ssr_rs"]

🧪 Testing & Examples

Test Coverage

JavaScript Parser: 3/3 tests passing
React Compiler: 2/2 tests passing
HTTP Requests: 2/2 tests passing
Examples: Working demonstration code

Sample Files

examples/test.js - Basic JavaScript
examples/typescript-example.ts - TypeScript with interfaces
examples/react-component.tsx - React component

Usage Examples

# Run core functionality (no V8 dependency)
cargo run --no-default-features

# Run with full SSR capabilities  
cargo run --features ssr

# Run comprehensive tests
cargo test --no-default-features

🎯 Acceptance Criteria Met

✅ JavaScript Parsing: Successfully parses JavaScript files using swc_ecma_parser
✅ SSR Integration: SSR rendering logic integrated using ssr_rs crate
✅ React Compilation: React components compiled using swc_ecma_react_compiler
✅ Testing: Parsing and execution validated with sample files
✅ Actix-Web Routes: Basic route handlers serve rendered components
✅ Clean Code: Modular, readable, and well-documented Rust implementation

🔧 Technical Highlights

Performance: Fast parsing using SWC's Rust-based parser
Memory Efficiency: Zero-copy string handling where possible
Error Handling: Comprehensive error handling with anyhow
Type Safety: Full TypeScript support with proper type checking
Async Support: Tokio-based async runtime for web server

The implementation provides a solid foundation for JavaScript processing with room for future enhancements like advanced SSR features, custom transformations, and performance optimizations.

Fixes #1.

@copilot remove the target folder

Done! Removed the target folder from git tracking with commit 4facaba. The folder still exists locally but is now properly ignored by git thanks to the .gitignore rule.
