Combine Bun's fast JavaScript runtime with Turborepo's intelligent caching for the ultimate monorepo setup. Learn workspace configuration, parallel task execution, and CI optimization strategies.
Bun, as a next-generation JavaScript runtime, combined with Turborepo is currently one of the best combinations for building high-performance monorepos—offering fast installation times and quick startup.
Key steps to introduce Bun into a Turborepo project: set "packageManager": "[email protected]" in the root package.json, and update the scripts in all sub-packages to be compatible with Bun.
Bun's built-in test runner can seamlessly replace Jest, running several times faster while supporting Jest's assertion API, making migration nearly frictionless. In a monorepo, you can run all tests uniformly with Bun.
Note that some packages requiring native Node.js APIs may have compatibility issues with Bun. It is recommended to test critical dependencies with bunx before migrating to confirm compatibility.
Turborepo's remote caching is fully compatible with Bun. You can continue to use Vercel's remote caching service. Combined with Bun's local speed advantages, overall CI time can be reduced by 40-60%.
