TypeScript Function Decorator Language Service Support

A TypeScript language service plugin that provides real-time transformation and IntelliSense support for function decorators in your IDE. This plugin works alongside the TypeScript compiler to provide a seamless development experience when working with function decorators.

Features

• 🔄 Real-time Transformation: See decorator transformations as you type
• 🎯 IntelliSense Support: Get accurate type information and autocompletion
• 🔍 Type Checking: Real-time type checking for decorated functions
• 🚀 Zero Configuration: Works out of the box with minimal setup

Installation

npm install -D ts-function-decorator-ls

Usage

1. Configure your IDE to use the workspace version of TypeScript:

{
  "typescript.tsdk": "node_modules/typescript/lib"
}

2. Add the language service plugin to your tsconfig.json:

{
  "compilerOptions": {
    "plugins": [
      {
        "name": "ts-function-decorator-ls"
      }
    ]
  }
}

3. The language service plugin will automatically provide support for function decorators:

// Create a decorator
const log = function (fn: Function) {
  return function (...args: any[]) {
    console.log('Function called with args:', args);
    return fn.apply(this, args);
  };
};

// Use the decorator
@log
function example(arg: string): string {
  return arg;
}

The plugin will provide:

• Editor support for function decorators
• Type checking for decorated functions
• IntelliSense support for decorator options
• Error reporting for invalid decorator usage
