NestJs in Practice (with MongoDB)

Discover NestJS: Build Robust Backend APIs with Angular Concepts

If you're an Angular developer looking to expand your skillset, NestJS is a powerful framework you need to know. Think of it as Angular for the backend! Leverage familiar concepts like components, services, and modules to structure your server-side applications, creating a seamless development experience. NestJS shares similarities with popular backend frameworks like Spring (Java) and ASP.NET MVC (C#), making the transition easier.

Course Overview: Build a REST API with NestJS and MongoDB

This comprehensive course guides you through building a complete REST API using NestJS to interact with a MongoDB database. We'll create a practical CRUD (Create, Read, Update, Delete) example, demonstrating common data retrieval and modification operations. No prior experience with NestJS, MongoDB, or Mongoose is required – we'll cover everything from the ground up.

You'll master essential NestJS concepts including:

• Modules, Controllers, and Injectable Services: The building blocks of a well-organized NestJS application.
• MongoDB Integration: Learn how to connect to and query a MongoDB database using the Mongoose ODM library.
• Data Validation: Implement robust data validation using decorators (@IsString(), @IsPhoneNumber(), etc.) and the built-in NestJS Validation Pipe.
• Security: Implement crucial backend security features like User Authentication, RBAC (Role-Based Access Control) Authorization, and comprehensive Error Handling.
• Advanced Concepts: Explore Filters, Pipes, Guards, Interceptors, and Middleware to enhance your application's functionality.
