This article walks you through setting up a project, writing failing tests first, implementing code to pass them, and refactoring with confidence. Discover how TDD improves code quality, reduces bugs, and simplifies maintenance for Node.js applications, including API testing. Master a practical workflow for building reliable and scalable applications.
Next.js allows you to create custom APIs with API routes defined in the pages/api directory. You can handle various HTTP methods (GET, POST, PUT, DELETE), use query parameters, connect to databases (e.g., SQLite), add middleware, implement authentication, and test with Jest.
