This is a complete guide to Turbopack, the Rust-powered bundler that replaced Webpack as the default in Next.js 16. It covers the config migration from experimental.turbopack to top-level syntax, CSS and module handling, tree shaking behavior, and how to replace webpack loaders with Turbopack rules or native features. The skill really shines when you're debugging HMR slowdowns, figuring out why your webpack loaders broke, or tracking down bundle size issues with the new built-in analyzer. If you're still using custom webpack loaders that have no Turbopack equivalent, it walks you through the fallback options and when to file an upstream issue.
