How to set up your first Nest.js project

Nest.Js is a progressive Node.Js framework used for building efficient, reliable, and scalable server-side applications. Nest.js- under the hood provides an abstraction for the Express/Fastify frameworks, providing you with an architecture you wouldn't find in the express framework. Nest.Js is not to be confused with Next.Js which is a frontend react framework for production. If you are interested in learning how to set up a Next.Js project you can read this article here.

Let's get you started..

So you've finally decided to go with nest.js and you intend to set up your first project, in order to do that here's what you need:

• Node.js latest version

• Nest.Js CLI

To install the Nest.js CLI use this command: $ npm i -g @nestjs/cli

Once you have installed the above requirements, you now have the opportunity to use the Nest.Js CLI, with this you can scaffold a new Nest.Js project with just a single command Nest new [New project name].

Step 2

Type the following command into your terminal Nest new [New project name] replace [New project name] with the name of your new project like the screenshot below:

Step 3

Pick your preferred package manager. I'd pick NPM for this article, as seen in the screenshot below.

allow packages to install

once that is done you should see this in your terminal

One last thing! You need to verify your folder structure to ensure the installation was correct, take a look at the folder structure below, that's what yours should look like.

Then finally you can start your project by running this command npm run start:dev

Congratulations! you've successfully set up your first Nest.js project!
