nextjs-turbopack

To fix slow development startup times in Next.js 16+, enable Turbopack for incremental bundling. This Rust-based bundler significantly accelerates cold starts and hot module replacement compared to traditional webpack workflows.

Turbopack file-system caching automatically reuses previous build work to minimize redundant processing during development server restarts. This incremental bundling mechanism ensures efficient hot module replacement for large-scale Next.js applications.

To enable Turbopack for your Next.js development environment, run the next dev command in your terminal. This starts the development server with the Rust-based incremental bundler activated for faster performance.

Turbopack replaces webpack for hot module replacement in Next.js 16+ by utilizing Rust-based incremental bundling. It provides significantly faster HMR and cold starts, optimizing high-performance frontend bundling workflows.

You should use Turbopack to troubleshoot Next.js performance bottlenecks when you experience sluggish development environments. It diagnoses and resolves slow startup times and inefficient hot module replacement in large-scale applications.
