Turbopack Adoption Guide

Introduction

In this adoption guide, we will explore Turbopack, a modern JavaScript bundler that integrates well with frameworks like React, Vue, and Angular. We'll discuss why Turbopack was created, its key features, and when to consider using it.

Why Turbopack?

Turbopack was developed to address the shortcomings of webpack, such as slow build times, poor hot module replacement, and limited tree shaking. It offers ease of use, smaller bundle sizes, and tight integration with Next.js.

How to Use Turbopack

Currently, Turbopack can only be used with the latest version of Next.js. By adding a flag to your Next.js project, you can leverage Turbopack as the bundler for your TypeScript codebase.

Key Features of Turbopack

• Turbo Engine: Built on a reusable Rust library for fast incremental builds.
• Internal Usage of swc: Utilizes swc for bundling TypeScript and JavaScript files.
• TypeScript Support: Supports TypeScript and Browserlist out-of-the-box.

Turbopack vs. Other Bundlers

While Turbopack offers speed and integration benefits, webpack and Vite are popular for their plugin ecosystems and community support. The choice between bundlers depends on project requirements, framework compatibility, and existing tooling.
