nestJS Modern Framework for Scalable Applications

Whether you’re building a small API or a large scale enterprise application, developers often seek tools that can handle complexity, scalability, and maintainability. NestJs can make that happen, its robust features make it a progressive nodeJs framework.

What is NestJS?

NestJS is a framework for building efficient and scalable server side applications, Its primary goal is to provide an out of the box application architecture that promotes clean code and organized project structures.It’s built on top of Node.js and uses typeScript though it also supports pure javaScript.

Few Features

  1. NestJS encourages a modular approach to application development. Imagine breaking a big school project into smaller, manageable tasks. That’s what modular architecture does. In NestJS, each feature or area of an application is like its own folder in a binder. This makes it easy to add new features or fix issues without affecting other parts of the app.

  1. Powerful CLI The Command Line Interface is a game changer for productivity. Instead of writing repetitive code you can use commands to generate parts of your app instantly. For example running nest generate module users creates all the files you need for managing users in seconds.

3.
TypeScript
TypeScript is like regular JavaScript, but with superpowers. It helps catch errors before you even run your app code like a spell checker for your code.. This makes programming less frustrating and more fun because you’ll spend less time hunting for bugs.
For Example: if you accidentally use a variable that doesn’t exist TypeScript will warn you right away..

4.
RestApi's

(Application Programming Interfaces)
are like menus at a restaurant. They tell users what’s available and how to order it. With NestJS you can create these menus using REST like a list or GraphQL like a build your own burger form.

To start using NestJS, you’ll need Node.js [a tool for running JavaScript] and the NestJS CLI.

npm install -g @nestjs/cli
nest new my-nest-app
Enter fullscreen mode Exit fullscreen mode

NestJS is like a Swiss Army knife for building apps. It has tools for everything & it’s perfect for big projects where you want to keep everything under control..used for almost anything like chatting apps to online stores.
