Course description

NestJS is a framework for Node.js designed for creating efficient, reliable, and scalable server-side applications. Its architecture is inspired by Angular, and thanks to this approach, NestJS has become popular, with more than 3 million downloads on NPM weekly.

When I was learning NestJS, I had to overcome a steep learning curve. I lacked a detailed and structured course that would simplify this process. That is why I created the "NestJS Masterclass": so that other developers wouldn't have to face such difficulties when learning NestJS.

Read more about the course

I guarantee that the "NestJS Masterclass" is the most detailed, comprehensive, and structured course on NestJS on the market! Nothing compares to this course, I promise you!

Practical Training in NestJS

Throughout the course, we create a server-side REST API for a blog, studying various NestJS features through real-world examples and delving into its internal mechanisms.

Thoughtful Structure and Curriculum

In creating the course curriculum, I invested a lot of time and effort to make learning NestJS as accessible as possible. The course covers all the key topics necessary for a deep understanding of the framework.

By the end of the course, you will confidently master NestJS and be ready to create complex server-side applications using this powerful framework.

Course Topics Overview:

  • NestJS Modules: Understanding the principles of how NestJS modules work, their internal structure and schemas, including services and providers.
  • Validation and Pipes: Learn how to use the class-validator package and Pipes for validating incoming data in a NestJS application.
  • Dependency Injection: Dive into the DI (Dependency Injection) system, ensuring the modularity of the application, including addressing cyclic dependencies.
  • Code Documentation: Explore NestJS capabilities for documenting APIs using Open API Specification and source code documentation with Compodoc.
  • TypeORM and Relational Databases: Use PostgreSQL and TypeORM integration for creating a REST API application, learning the intricacies of working with databases.
  • Database Relations: Master relationships between tables in SQL: one-to-one, one-to-many, and many-to-many, clarifying possible misconceptions on these topics.
  • Environment Configuration: Learn how NestJS manages configurations for different environments.
  • Exception Handling: Elegant management of exceptions to enhance user and developer experience.
  • Database Transactions: Study TypeORM transactions for safely executing related operations.
  • User Authentication with JWT: Build a JWT-based authentication system for application security.
  • Guards and Decorators: Use Guards for request filtering and decorators for metadata and data transmission.
  • Google Authentication: Use Google OAuth to simplify registration.
  • File Upload: Implement a file upload mechanism to the server using Interceptors.
  • Unit Testing and End-to-End Testing: Create unit tests to ensure high code quality.
  • Mongoose and MongoDB: Work with NoSQL databases like MongoDB using Mongoose.
  • Deployment to AWS: A complete guide to deploying a production application on AWS, including using CloudFront and S3 for media file storage.
