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.
   **EXAMPLE: **a module for user management could have its own code and not interfere with a module for handling payments.

2. 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..
