Building a REST API with Node.js is straightforward. Building one that's maintainable at scale — with proper typing, input validation, authentication, error handling, and testability — takes significantly more thought. TypeScript eliminates whole categories of bugs that plague JavaScript APIs. Combined with modern tooling like Zod for runtime validation, Prisma for database access, and structured error handling, you get an API codebase that a team can confidently work in for years. This guide walks through building a production-ready REST API from scratch. You can test the endpoints we build with our API Tester and format response payloads with the JSON Formatter. Project Setup mkdir my-api && cd my-api npm init -y # TypeScript + build tools npm install -D typescript ts-node nodemon @types/node npm install -D @types/express # Core dependencies npm install express npm install zod # Runtime validation npm install prisma @prisma/client # Database ORM npm install jsonwebtoken @type
