- Turbopack is designed for fast iteration loops using caching and incremental computation.
- It is the default bundler for Next.js, aimed at enabling instant builds and fast React Fast Refresh.
- Turbopack's architecture is built with caching in mind, drawing from research and tools like Salsa, Parcel, and Rust compiler's query system.
- It uses fine-grained caching with 'value cells' to track dependencies and minimize recomputation.
- Turbopack's approach avoids manual dependency graphs, reducing errors and improving efficiency.
- The system marks dirty cells and propagates changes efficiently, only recomputing when necessary.
- Aggregation graphs help in efficiently querying large portions of the dependency graph.
- File system caching was introduced in Next.js 16.1, persisting caches to disk for faster restarts.
- The development of file system caching took over a year to meet performance and quality standards.
