What is Turbopack?

Turbopack is a modern frontend bundler and dev server created by the Vercel team as a replacement for Webpack. It is written in Rust, which makes it significantly faster than JavaScript-based tools thanks to low-level optimization and efficient memory management.

#Key features of Turbopack

1. A very fast dev server Uses incremental building and caching, processing only the changed modules, not the whole project.
2. Incremental architecture Turbopack does not rebuild the entire project on changes, only the necessary parts of the dependency graph.
3. High performance thanks to Rust Code runs faster and more efficiently than equivalent JS-based solutions.
4. Compatibility with the Webpack ecosystem Turbopack's developers position it as the "next step after Webpack" and keep similar concepts (bundling, HMR, module loading).

#What it is used for

• fast startup and code updates during development
• building frontend applications for production
• speeding up large projects where Webpack or Vite start to hit performance limits

#Summary

Turbopack is a next-generation bundler focused on ultra-fast development and builds, with an architecture based on incremental processing and maximum caching.
