Nestjs is a framework for developing scalable and efficient Mode.js server-side applications. It utilizes progressive JavaScript, is developed with, and entirely supports TypeScript, and combines elements of object-oriented programming, functional reactive programming, and functional programming. It also allows developers to code in pure JavaScript. 

Behind the scenes, Nest utilizes powerful HTTP server frameworks such as Fastify and Express. Nest offers a certain level of the outline above these frameworks while directly exposing their APIs to the developers. 

This facilitates easy utilization of the different third party modules that are available in each platform. Est utilizes popular existing frameworks such as Express and Node.js and plays the role of a layer above. 

Why the Popularity of Nestjs?

Nestjs is purely written in TypeScript and you can use it to execute your applications out of the box in TypeScript. It offers an out of the box application structure which was inspired by Angular. Still, Nest is a different independent project that’s different from the Angular project. With this framework, you can develop a front end API which can be integrated with other frameworks and libraries such as Vue.js and React. 

TypeScript

TypeScript offers the flexibility of JavaScript with the robustness and safety of a typed language. While Nest applications can be written in TypeScript, you can also write them in JavaScript but many experts don’t recommend it. 

TypeScript is accumulated to JavaScript which means that the accumulator can get exposed to potential runtime errors during the assembly process. The language defines itself as JavaScript that scales and Nest are designed to offer a scalable backend structure which is a great idea. 

Further, experts recommend the use of TypeScript in your current frontend framework. Angular offers TypeScript out of the box but users can also utilize it in other commonly used frameworks such as Vue and React. 

This way, developers can have a common language in their frontend and backend code where they can also share their preferred definitions. This concept cuts down the efficiency losses highly through context switches from one language to the other. It can also improve the performance of your team. 

Nest Architecture

Nest’s structure was highly inspired by Angular. 

Often, server-side JavaScript frameworks target flexibility that offering a scalable structure for your code. Usually, developers should invest time to arrange the code clearly and outline guidelines for the same. Nest offers an appropriate out of the box structure that comprises of services, controllers, and modules.
