Welcome to the ultimate NestJS tutorial! 🎉 In this comprehensive guide, we'll dive deep into the world of NestJS, the powerful framework for building efficient, scalable Node.js server-side applications. Whether you're a beginner or an experienced developer looking to level up your skills, this video has something for everyone!
🔰 What is NestJS?
NestJS is a progressive Node.js framework that helps you build efficient, reliable, and scalable server-side applications. It uses modern JavaScript, is built with TypeScript, and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming).
🛠️ Setting Up Your Development Environment:
We'll start by setting up your development environment. You'll need Node.js and npm installed. Then, we'll install the NestJS CLI globally:
```
npm i -g @nestjs/cli
```
📦 Creating Your First NestJS Project:
Let's create our first NestJS project using the CLI:
```
nest new project-name
```
🏗️ Understanding NestJS Architecture:
NestJS follows a modular architecture. We'll explore:
Modules
Controllers
Providers (Services)
Dependency Injection
🔄 RESTful API Development:
We'll build a RESTful API, covering:
Route handling
Request parsing
Response formatting
Error handling
🔐 Authentication & Authorization:
Learn how to implement secure authentication and authorization in your NestJS applications using:
Passport strategies
JWT (JSON Web Tokens)
Guards
🗄️ Database Integration:
We'll connect our NestJS app to a database using:
TypeORM
Mongoose (for MongoDB)
🧪 Testing in NestJS:
Discover how to write and run tests for your NestJS applications:
Unit tests
Integration tests
E2E tests
📊 Swagger Integration:
Learn how to automatically generate API documentation using Swagger/OpenAPI.
🚀 Deployment:
We'll wrap up by deploying our NestJS application to a cloud platform.
