Installation

Get started with Macroforge in just a few minutes. Install the package and configure your project to start using TypeScript macros.

Requirements

• Node.js 24.0 or later
• TypeScript 5.9 or later

Install the Package

Install Macroforge using your preferred package manager:

npm install macroforge

bun add macroforge

pnpm add macroforge

Basic Usage

The simplest way to use Macroforge is with the built-in derive macros. Add a @derive comment decorator to your class:

/** @derive(Debug, Clone, Eq) */
class User {
  name: string;
  age: number;

  constructor(name: string, age: number) {
    this.name = name;
    this.age = age;
  }
}

// After macro expansion, User has:
// - toString(): string         (from Debug)
// - clone(): User              (from Clone)
// - equals(other: User): boolean  (from Eq)

IDE Integration

For the best development experience, add the TypeScript plugin to your tsconfig.json:

{
  "compilerOptions": {
    "plugins": [
      {
        "name": "@macroforge/typescript-plugin"
      }
    ]
  }
}

This enables features like:

• Accurate error positions in your source code
• Autocompletion for generated methods
• Type checking for expanded code

Build Integration (Vite)

If you're using Vite, add the plugin to your config for automatic macro expansion during build:

import macroforge from "@macroforge/vite-plugin";
import { defineConfig } from "vite";

export default defineConfig({
  plugins: [
    macroforge({
      generateTypes: true,
      typesOutputDir: ".macroforge/types"
    })
  ]
});
