Node.js is used to develop server-side web applications. It is an open source and cross-platform runtime environment. The built-in libraries in Node.js allow applications to act as a standalone web server. Node.js can be used in scenarios where lightweight, real-time response is needed, such as communication apps and web-based gaming.
Node.js is available for various platforms, such as Windows, Linux, Mac OS X, Sun OS, and ARM. You can also download the source code of Node.js and customize it according to your needs.
In order to install Node.js, navigate to https://nodejs.org/en/ and download the mature and dependable LTS (long-term support) version for Windows.
Node.js comes with NPM, a package manager that is used to acquire and manage JavaScript libraries for your development. To verify that the installation of Node.js and NPM is successful, follow these steps:
- Open Windows Command Prompt, type the node -v command, and run it. You will get the version of Node.js that we installed.
- Now, check whether NPM is installed along with Node.js. Run the NPM -v command, and you will get the version number of NPM that is installed.
Now, we have all that we need to write our first Angular application. Let's get started.
