Day 30: Final Recap and Publishing

Mission Accomplished

Welcome to Day 30! You made it. You started with const x: number and ended building a Generic API Client.

The Journey

1. Foundations: Types, Interfaces, Functions.
2. OOP: Classes, Inheritance, Access Modifiers.
3. Advanced Types: Unions, Intersections, Generics.
4. Type Manipulation: keyof, Mapped Types, Conditional Types.
5. Real World: configuration, Async modules.

Next Steps: Publishing

You have a utils.ts full of helper functions. Why not share it?

1. Run npm init to create package.json.
2. In tsconfig.json, set "declaration": true to generate .d.ts files.
3. Run tsc.
4. Run npm publish.

Now anyone can npm install your-package and get full type support!

Final Words

TypeScript is a journey. The best way to learn is to build. Go forth and type safely!

Thank you for following along!
