Synopsis

Updated for 2026

Do you want to publish high-quality TypeScript packages to NPM without struggling with complicated setups or unreliable release scripts?

Creating NPM Package is a hands-on, step-by-step guide that walks you through every stage of building a modern TypeScript library, from setting up your project to automating production releases.

This new edition includes the latest best practices, such as using semantic-release for automated versioning and release notes, setting up secure NPM Trusted Publishing, and a new chapter on making your TypeScript codebase more modular and scalable.

If you’ve ever asked yourself questions like these:

  • How should I structure my TypeScript library?
  • How do I compile to both ESM and CommonJS correctly?
  • How do I automate versioning and changelogs without manual work?
  • How do I securely publish using modern CI workflows?
  • How do I scale my library beyond a single file?

This book gives you clear, practical answers to all of these questions.

What You’ll Learn Inside
  • Configure a clean, scalable TypeScript project
  • Compile to both ECMAScript (ESM) and CommonJS (CJS) modules
  • Properly separate source code and distribution builds
  • Define correct entry points and declaration files
  • Modularize your TypeScript codebase for maintainability
  • Test your package before and after publishing
  • Automate version management and release notes using semantic-release
  • Implement NPM Trusted Publishing for secure, tokenless releases
  • Create professional README and LICENSE files
  • Publish and validate your package in both local and production environments

This book is more than just a tutorial. It gives you a repeatable system you can use for different projects.

Why Choose This Book
  • Clear, simplified explanations without unnecessary theory
  • Real-world workflows used by professional library authors
  • Automation-first approach to eliminate manual release headaches
