How does Bun improve development speed compared to Node.js?

Bun offers significantly faster startup times (around 25ms), package installation that is 10-100x faster than npm, and native support for TypeScript and JSX, removing the need for external transpilers like ts-node or babel.

Does Bun support all Node.js built-in modules?

Bun implements high-performance versions of most Node.js APIs (like fs, path, and crypto) and supports the 'process' and 'Buffer' globals, ensuring broad compatibility with the existing npm ecosystem.

Can I use this skill to migrate my current project to Bun?

Yes, the skill includes specific workflows for replacing package managers, updating package.json scripts, and handling Node.js compatibility issues during migration.

How do I run tests using Bun?

Bun includes a built-in test runner accessible via the 'bun test' command. It supports Jest-like syntax, provides native code coverage, and is significantly faster than traditional test runners.
