The script attempts to add the following lines to the correct profile i.e, ~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc. We can also use the wget command to download the script. We see this from the command where we have piped the downloaded script to the bash command for execution. After it has downloaded the script, we execute it. If not, we install it by executing the following curl command that fetches the installation script - install.sh and runs it locally: $ curl -o- | bashįrom the command output, we see curl working. To check if NVM is available in our system, we can check its version: $ nvm -version For example, if we are currently using Node.js version 6 and wish to switch to version 16, we write: $ nvm use 16Īdditionally, while installing Node.js using the Node Version Manager, its package manager NPM is also installed automatically. We can also have other versions of Node.js installed and occasionally switch between them. For example, to install node.js version 6, we write: $ nvm install 6
With NVM, it is much easier to install, switch between and remove Node.js versions. To manage them, we use the NVM(Node Version Manager). There exist different versions of Node.js. We use it to install packages and project dependencies, in this article, we use it to install Angular CLI, which we will look at shortly. Furthermore, using Node.js, we can create a lightweight web server to host our application locally. However, we need it for all build and development tools. So how do AngularJs, Node.js, and NPM relate to each other? It is not mandatory to use Node.js. Node.js is a cross-platform run-time environment used to run javascript outside the browser, npm, is its package manager and nvm its version manager. We learn how to create AngularJs applications in the Ubuntu operating system. Some of its features include routing, client-server communication, MVC framework, two-way data binding, dependency injection, testing, custom components.
It was developed and is currently being maintained by Google. With it, we can build scalable single-page applications(SPAs) using HTML and Typescript. Table of contents.ĪngularJs is a Javascript framework. In this article, we learn how to install AngularJs Javascript Framework in Linux Ubuntu.
