# TypeScript Pro

For when the types stop being simple

## What this does

Your TypeScript has reached the point where the type system is its own problem. This helps with the hard type work and connects your front end and back end so mistakes show up while you type rather than at runtime. Reach for it when types get complex or a monorepo needs setting up.

### Top 3 things it does for you

- Write advanced generics and conditional types
- Add custom type guards and branded types
- Set up a monorepo

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About TypeScript Pro

This implements advanced TypeScript type systems, creates custom type guards, utility types and branded types, and configures tRPC for end-to-end type safety.

Use it when a TypeScript application needs advanced generics, conditional or mapped types, discriminated unions, a monorepo setup, or full-stack type safety with tRPC.

## Questions

### Is TypeScript Pro safe to install?

AIR scanned this exact version of TypeScript Pro and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 5e8b6b8ff400, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/typescript-pro.

### How do I install TypeScript Pro?

Open https://airmarket.ai/app/typescript-pro on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up.
