NestJS is one of the most modern Node.js frameworks available today. This course is designed to teach you everything you need to know to get started quickly and effectively! Unlike lengthier courses that often contain unnecessary chit-chat, this course focuses solely on delivering meaningful content. We prioritize your time and ensure that every minute of the course is filled with essential information. We'll begin with the basics, such as routing and controllers.
Database Integration with TypeORM
Next, we'll dive into database topics using the TypeORM framework, covering areas such as the repository pattern, query building, and handling relations. You can choose to work with either MySQL or Postgres throughout the course.
We'll be using Docker to manage your database environment, reflecting the most modern and practical approach you'll encounter in real-world applications. An understanding of Docker and its operations is integral to the course content.
NestJS Deep Dive
We'll delve into the mechanics of how NestJS operates, including complex concepts like Providers and Dependency Injection. These are powerful features that, although challenging at first, are explained clearly to ensure you grasp their importance and functionality.
Authentication and Authorization
The course covers authentication and authorization—key components of any application for managing user access and security. We'll explore how these are implemented in NestJS, along with comprehensive examples. A thorough exploration of JWT Tokens is also included, ensuring no crucial aspects are overlooked.
Authentication is managed using Passport.js, a standard Node library, equipping you with practical skills in this vital area.
Testing and API Usage
We also explore Unit testing and End-to-End testing, teaching you how to execute these tests effectively within Nest. The course includes ample examples and scenarios reflecting real-world situations you are likely to encounter.
Additionally, we incorporate Postman for API interaction and testing, providing insights into its use beyond simple calls—including collections, environment setup, and automation.
Build a Real-World Application
This is not about creating another theoretical example; you will build a practical API for an existing frontend project (built with Vue 3) provided in the course. You will develop an API for an event attendance application, making the learning process engaging and applicable.
