TypeScript Projects with Source Code

TypeScript Projects by Stack

Our TypeScript collection covers frontend, backend, and full-stack applications.

React + TypeScript

React projects with properly typed components, hooks, context, and API calls. Projects demonstrate generic components, discriminated union props, and typed event handlers. State management uses typed Redux Toolkit or Zustand.

Node.js + TypeScript

Express and Fastify backends with typed request/response objects, middleware, and database models. Prisma or TypeORM handles database operations with full type inference. API routes have typed validators using Zod or Yup.

Next.js + TypeScript

Full-stack Next.js applications with typed API routes, server components, and shared type definitions. Projects use tRPC or typed fetch wrappers for end-to-end type safety between client and server.

Running TypeScript Projects

Run npm install to get dependencies including TypeScript compiler. Development uses npm run dev with ts-node or tsx for hot reloading. Production builds compile to JavaScript with npm run build.

Why TypeScript

TypeScript catches entire categories of bugs before your code runs — undefined property access, wrong argument types, missing return values. Our projects use strict mode for maximum type safety. The code serves as a learning resource for TypeScript patterns you'll use in professional development.
