NestJS has emerged as one of the most powerful frameworks for backend development in Node.js, offering a modular and scalable architecture for building server-side applications. If you’re eager to master this technology and create high-performance RESTful APIs, then the ‘Complete NestJS Course: The Definitive Guide for RESTful API Development with TypeORM and JWT Authentication’ on Udemy is the right investment for you.
### Course Overview
This comprehensive course consists of over 100 detailed lessons that cover everything from the basics to advanced implementations of authentication, authorization, automated testing, and production deployment. Here’s what you can expect to learn:
#### Introduction to NestJS
The course kicks off with an introduction to NestJS, explaining what makes this framework special. With a module-based approach, NestJS facilitates code organization, component reuse, and scalability. You’ll also learn about the main requirements of NestJS and how to set up your development environment correctly.
#### Installing and Configuring NestJS CLI
One of the first steps is installing the NestJS CLI, a powerful command-line tool that streamlines project creation and code generation. This section helps you understand the basic files generated and their purposes, such as the `main.ts` file that initializes your application.
#### Creating Modules and Controllers
Modules and controllers are central components in NestJS. You’ll learn to create these components manually and using the NestJS CLI, encapsulating functionalities and creating dynamic routes.
#### Understanding HTTP Protocol
To develop effective RESTful APIs, a solid understanding of the HTTP protocol is essential. This course dedicates a section to the basics of HTTP, including URLs, resources, and request methods such as GET, POST, PUT, PATCH, and DELETE.
#### Dependency Injection with Services and Providers
One of the most powerful features of NestJS is its dependency injection implementation. The course covers how to create and configure services (providers) that handle business logic, keeping your code modular and organized.
#### Data Validation and Transformation
Ensuring that incoming data is valid is crucial in API development. The course teaches you how to create Data Transfer Objects (DTOs) and use ValidationPipe and class-validator to validate incoming data efficiently.
#### Implementing Security with JWT
Security is a top priority for any API. This course dives deep into implementing authentication and authorization using JWT. You’ll learn to create a secure login system, hash passwords with bcrypt, and configure authentication guards to protect routes.
#### Exception Handling
A good API should provide clear error responses. You’ll learn to use HttpException and NotFoundException to show appropriate error messages and how to create custom Exception Filters.
#### Pipes and Interceptors
NestJS offers Pipes for validating and transforming data in routes. You’ll see how to use Pipes to ensure data is in the correct format and how Interceptors can modify HTTP responses.
#### Database Integration with TypeORM and PostgreSQL
Most applications need to interact with a database. This course covers integrating PostgreSQL using TypeORM, including creating entities and repositories to perform CRUD operations.
#### Pagination and Filtering
The course teaches how to implement pagination in APIs, which is essential for managing large datasets.
#### Advanced DTOs and Custom Validation
For complex systems, advanced DTOs and validations are necessary. You’ll learn to implement custom validations for various scenarios.
#### File Uploads and Serving Static Content
If your application needs to handle file uploads, the course covers using FileInterceptor and serving static files.
#### Automated Testing
Quality assurance is vital, and the course explains how to implement unit and end-to-end tests using Jest, ensuring your application functions as expected.
#### Production Deployment
Finally, the course shows you how to deploy your NestJS application using Google Cloud Platform, covering server setup, SSL certificates, and process management.
### Why This Course is a Valuable Investment
The Complete NestJS Course is more than just a beginner’s guide. It covers all aspects of backend development with NestJS, from initial setup to production deployment, security, testing, and more. Each lesson is designed to provide practical knowledge, equipping you to develop robust and secure RESTful APIs.
