GitHubDev Utilities & Vibe-Coding Tooling · Build & DX CLI
Rolldown-powered bundler for TypeScript libraries that emits ESM, CJS and declaration files from a minimal config.
Why it’s a gem
The tsup successor built on Rust internals, already shipping in antfu's own projects.
Node.js runtime wrapper that executes TypeScript and ESM files directly with esbuild, including watch mode and REPL.
Type-safe CLI framework with zero runtime dependencies where commands are classes and argument types flow into your handler.
Dependency upgrade CLI that shows a per-package diff of available versions and applies bumps across every workspace at once.
Single CLI that pins language and tool versions per project, loads environment variables, and runs project tasks from one TOML file.
Release CLI that bumps package versions, updates the changelog, creates the git tag and pushes, with an interactive prompt.
Package manager shim that detects the lockfile and runs the right npm, yarn, pnpm or bun command from one short alias.
