nodejs install angular

Node.js is a JavaScript runtime based on the Chrome V8 engine, which allows you to develop background programs using the JavaScript language. At the same time, Node.js is also a powerful tool that can greatly reduce development time and workload between front-end and back-end.

Angular is a web application framework that helps you build dynamic and scalable web applications. Angular is written using TypeScript language, and it is an upgraded version of AngularJS.

In this article, we will learn how to install Angular in Node.js.

Step One: Install Node.js

In order to install Angular, we first need to install Node.js. You can download the latest version of Node.js from the official website (https://nodejs.org/) and select the corresponding version according to your operating system.

After the installation is complete, you can enter the following command on the command line to verify whether Node.js is successfully installed:

node -v

If you successfully installed Node.js, then you will see Node The version number of .js.

Step 2: Install Angular CLI

Angular CLI is a command line interface tool that can help us quickly create and build Angular applications. We can use npm (the package manager that comes with Node.js) to install Angular CLI.

Enter the following command on the command line to install Angular CLI:

npm install -g @angular/cli

This command will install Angular CLI globally. After the installation is complete, you can enter the following command on the command line to verify whether Angular CLI is installed successfully:

ng version

If you installed Angular CLI successfully, you will see the version number of Angular CLI.

Step 3: Create an Angular application

Now that we have successfully installed Node.js and Angular CLI, we can start creating an Angular application. Enter the following command at the command line to create a new Angular application:

ng new my-app

This command will create a new Angular application named "my-app" and add all necessary files and dependencies items are downloaded to your computer.

Creating the application will take some time, depending on your network bandwidth and your computer's processing power. Once completed, you can go into the "my-app" directory and start the application:

cd my-app
ng serve

This command will start a local server and serve the application on the default port (4200). You can access the application by opening your browser and entering "http://localhost:4200" in the address bar.

Now, you have successfully installed Angular and created a new Angular application!

Summary

In this article, we learned how to install Angular in Node.js.

We first installed Node.js and then installed Angular CLI globally using npm. Finally, we created a new Angular application using the Angular CLI and started a local server to serve the application.

If you are a JavaScript developer and want to develop front-end applications, Angular is a very good choice. The combination of Node.js and Angular allows you to develop high-quality web applications faster and reduce project development time and effort.
