Introduction

Nest is a framework for building efficient, scalable Node.js server-side applications. It uses progressive JavaScript, is built with TypeScript (preserves compatibility with pure JavaScript) and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming).

Under the hood, Nest makes use of Express, but also provides compatibility with a wide range of other libraries (e.g. Fastify). This allows for easy use of the myriad third-party plugins which are available.

Philosophy

In recent years, thanks to Node.js, JavaScript has become the “lingua franca” of the web for both front and backend applications. This has given rise to awesome projects like Angular, React and Vue which improve developer productivity and enable the construction of fast, testable, and extensible frontend applications. However, while plenty of superb libraries, helpers, and tools exist for Node (and server-side JavaScript), none of them effectively solve the main problem - architecture.

Nest provides an out-of-the-box application architecture which allows for effortless creation of highly testable, scalable, loosely coupled, and easily maintainable applications.

Installation

To get started, scaffold the base project with the Nest CLI:

$ npm i -g @nestjs/cli
$ nest new project-name

Install the starter project with Git:

$ git clone https://github.com/nestjs/typescript-starter.git project
$ cd project
$ npm install
$ npm run start

$ git clone https://github.com/nestjs/javascript-starter.git project
$ cd project
$ npm install
$ npm run start

Or start a new project from scratch with npm (or yarn):

$ npm i --save @nestjs/core @nestjs/common rxjs reflect-metadata
