1. What is NestJS?2. Core Concepts
Introduction to NestJS
NestJS is a progressive Node.js framework for building efficient, reliable, and scalable server-side applications.
NestJS leverages TypeScript and is built around the concepts of modules, controllers, and providers.
Setting Up a NestJS Project
To start a new NestJS project, you need to have Node.js and npm installed. Use the Nest CLI to create a new project with the command: `nest new project-name`.
Understanding Modules
Modules are the basic building blocks of a NestJS application. They help organize the application structure by grouping related components.
Controllers and Providers
Controllers handle incoming requests and return responses to the client. Providers are used for services and can be injected into controllers or other providers.
