Is Bun.$ safer than traditional shell execution in Node.js?

Yes, Bun.$ uses tagged templates to automatically escape interpolated values, providing a cross-platform and injection-safe way to run shell commands within your scripts.

Does this skill support automated testing?

Yes, it provides full support for bun:test, which is a fast, Jest-compatible test runner built directly into Bun that supports mocking and snapshots.

Can Claude help me migrate from npm or Yarn to Bun?

Absolutely. This skill understands Bun's package management conventions, lockfile formats, and performance advantages during the migration process.

Why should I use Bun-native APIs instead of Node.js polyfills?

Bun-native APIs are specifically optimized for the Bun runtime, offering significantly better performance and lower memory overhead compared to Node.js compatibility layers.
