Inside Turbopack: Building Faster by Building Less
Summary
Turbopack is pitched as the Next.js default bundler that speeds up builds by computing only incremental changes rather than rebuilding the entire app. It introduces fine-grained caching via value cells, a dirty-propagation mechanism, and an aggregation graph, plus a persistent file-system cache to resume work quickly. The article contrasts this approach with traditional manual dependency graphs and older bundlers, highlighting the goal of instant builds for large-scale applications.
