TypeScript Package Setup Guide

This guide outlines how to set up a simple TypeScript package with build and test scripts.

1. Initialize Your Package

npm init -y

2. Install TypeScript and Essential Dependencies

npm install typescript @types/node tsup --save-dev

3. Set Up TypeScript Configuration

npx tsc --init

4. Create Package Structure

my-ts-package/
├── src/
│   ├── index.ts        # Main exports
│   ├── utils.ts        # Utility functions
│   └── types.ts        # Type definitions
├── test/               # Tests
├── dist/               # Compiled output
├── package.json
└── tsconfig.json

5. Example Package Code

src/index.ts

export * from './utils';
export * from './types';

src/utils.ts

export function greet(name: string): string {
  return `Hello, ${name}!`;
}

export function sum(a: number, b: number): number {
  return a + b;
}

src/types.ts

export interface User {
  id: string;
  name: string;
  email: string;
}

6. package.json Scripts

"scripts": {
  "build": "tsup src/index.ts --format cjs,esm --dts",
  "dev": "tsup src/index.ts --format cjs,esm --dts --watch",
  "test": "jest",
  "prepublishOnly": "npm run build"
}
