About This Series
Command-line tools are one of the most satisfying things to build—they’re fast, focused, and incredibly useful. This series takes you from an empty directory to a published npm package.
What You’ll Learn
- Project setup: TypeScript configuration, package.json bin field, and shebang lines
- Argument parsing: Using libraries like commander or yargs for clean option handling
- User experience: Interactive prompts, spinners, colors, and progress bars
- Distribution: Testing locally, publishing to npm, and versioning
Prerequisites
- Node.js and npm/pnpm installed
- Basic TypeScript knowledge
- Familiarity with the terminal
