Nest.js Developer Lab 2026: Build a Robust API with Authentication, Articles, and User Profiles

This course is designed to take you through the process of building a real-world API with Nest.js. Start by setting up your environment and exploring the core technologies such as Nest.js, Postgres, and JWT authentication. Learn how to build and structure essential modules such as tags, articles, and user profiles. Each section is carefully designed to provide you with a strong foundation in API development, covering topics like database migrations, data transfer objects, and authentication middleware. Additionally, learn how to implement features like liking and disliking articles, following users, and generating personalized feeds, enhancing the interactivity of your app. The final lessons cover back-end validation and front-end testing, ensuring your API is secure and efficient. You’ll also get a chance to complete a hands-on exercise to practice using your new skills. By the end of this course, you’ll be prepared to build and deploy your own scalable Nest.js applications.
