@jterrazz/typescript

Drop-in TypeScript build tooling with zero configuration.

Installation

npm install @jterrazz/typescript

Usage

1. Choose a TypeScript configuration

// tsconfig.json - Pick one:
{ "extends": "@jterrazz/typescript/presets/tsconfig/node" }  // Node.js projects
{ "extends": "@jterrazz/typescript/presets/tsconfig/next" }  // Next.js projects
{ "extends": "@jterrazz/typescript/presets/tsconfig/expo" }  // Expo/React Native

2. Use the CLI

npx typescript build       # Build application (ESM + types)
npx typescript bundle      # Bundle library (ESM + CJS + types)
npx typescript start       # Run the built application
npx typescript dev         # Build, run, and rebuild on changes

What you get

• Blazing fast — Powered by tsdown / Rolldown (Rust)
• Zero configuration — Works out of the box
• Multiple outputs — ESM + CommonJS + TypeScript declarations
• Source maps — Full debugging support

Build outputs

| Command | Output | Description | | ------------------- | ----------------- | ----------------------- | | typescript build | dist/index.js | ESM bundle | | | dist/index.d.ts | TypeScript declarations | | typescript bundle | dist/index.js | ESM bundle | | | dist/index.cjs | CommonJS bundle | | | dist/index.d.ts | TypeScript declarations | | typescript start | — | Runs dist/index.js | | typescript dev | dist/index.js | Watch + rebuild + run |

Project structure

│   ├── index.ts           # Main entry point

└── tsconfig.json          # Extends this package

How it works

The package uses a fully compiled toolchain — no JavaScript in the hot path:

| Step | Tool | Language | | ------------ | ------------------------------------- | -------- | | Transpile | Oxc (via tsdown) | Rust | | Bundle | Rolldown | Rust | | Declarations | tsdown built-in | Rust |
