Npx Cli

This is a complete starter kit for building CLI tools that run via npx, using Bun for development but targeting Node.js for distribution. It scaffolds the full setup: citty for argument parsing, Bunup for bundling, dual package structure if you want both a library API and a binary, plus the whole TypeScript strict mode and testing rig. The opinonated part is good here: it forces the shebang to use node not bun, makes you separate CLI wiring from actual logic so tests don't spawn processes for every assertion, and includes both Biome and ESLint because one is fast and the other catches type-level mistakes. If you're publishing something people will npx, this handles the easy-to-mess-up parts like the bin field and executable permissions.
