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.**For the reviewerNote to the moderator (optional)Visible only to the moderator.
