NestJS is a progressive Node.js framework for building efficient and reliable server-side applications. It uses TypeScript by default and encourages clean, modular code with concepts including controllers, services, and dependency injection.
We just published a NestJS course on the freeCodeCamp.org YouTube channel that will help you harness it’s modular architecture, TypeScript support, and built-in tools to create clean, testable, code.
In this course, you'll explore controllers, services, modules, decorators, pipes, guards, and exception handling - all while building the profile feature for DevMatch, a dating app for developers.
You’ll implement profile creation, updates, and data retrieval while exploring the full lifecycle of a NestJS backend. By the end, you’ll have a solid foundation in NestJS fundamentals, plus the confidence to apply these skills to your own APIs and applications.
The course covers:
Understand NestJS fundamentals: modules, decorators, and structure.
Build controllers to handle GET, POST, PUT, and DELETE requests.
Connect controllers to services to manage application logic.
Implement validation and transformation with pipes.
Handle errors gracefully with exception filters.
Use guards to manage application security and access control.
Solve hands-on challenges that reinforce each concept.
Watch the full course on the freeCodeCamp.org YouTube channel (2-hour watch).
