bun

The Bun skill provides an integrated environment for developers looking to transition from Node.js to Bun for faster JavaScript and TypeScript development. It serves as an AI-powered assistant for executing, managing, and debugging modern JS/TS runtimes. This skill is designed for full-stack developers, DevOps engineers, and library maintainers who want to leverage Bun's native performance, built-in bundler, and fast package manager to streamline their development lifecycle.

• Seamless mapping of npm, yarn, and node commands to bun, bunx, bun install, bun add, and bun run.

• Comprehensive project scaffolding including bun init, bun create, and template-based setup for frameworks like Next.js and Vite.

• Advanced dependency handling: automatic management of bun.lockb, devDependencies, and secure installation patterns to mitigate typosquatting risks.

• Built-in TypeScript support allowing direct execution of .ts and .tsx files without manual compilation steps.

• CI/CD integration guides, including GitHub Actions configuration with oven-sh/setup-bun and testing automation workflows.

• Migration support for existing Node.js codebases, providing best practices for runtime compatibility and performance optimization.

• Utilize this skill when starting new projects or converting existing Node.js projects to Bun.

• Always verify package names before executing bun add to avoid malicious packages in the npm registry.

• Ensure that sensitive scripts are not directly executed from external URLs; prioritize local project-based execution for security.

• Pay attention to the binary lockfile format (bun.lockb), which must be committed to source control and not ignored.

• The skill activates automatically when detecting keywords such as bun, bunx, bun.lockb, or during package.json manipulation tasks.

• Suitable for both development environments and production CI pipelines requiring fast build times and reduced cold-start latency.
