A tiny CLI in TypeScript

Placeholder introduction for a tutorial post.

Setup

Run this command to create the project:

npm init -y && npm install tsx

The code

#!/usr/bin/env tsx
const [, , name = 'world'] = process.argv;

function greet(who: string): string {
  return `Hello, ${who}!`;
}

console.log(greet(name));

Placeholder paragraph. Inline code looks like greet('you').

Next steps

1. Add argument parsing.
2. Add tests.
3. Publish to npm.
