Angular.js is an open-source JavaScript-based web application framework developed and maintained by Google. Its primary goal is to simplify both development and testing of applications by providing a model–view–controller (MVC) architecture along with components commonly used in internet applications.
This framework has two main features:
1. Two-way data binding: This means that any changes in the user interface would immediately influence application objects and vice versa.
1. Dom manipulation: Angular.js brings traditional server-side services, such as view-dependent controllers, to client-side web applications. Consequently, page loading speed is significantly improved.
To use Angular.js, we need to follow the steps below:
1. Set up the environment: The first step is installing Node.js and npm (Node Package Manager) to manage our libraries.
1. Set up a new project: Run the command “ng new MyFirstAngularApp” in the terminal. Here ‘MyFirstAngularApp’ would be your project name.
1. Go into the project directory: Use “cd MyFirstAngularApp.”
1. Run the project: Use the “ng serve” command, which will compile and open your app in a browser. If you want to modify the port, you can use “ng serve —port your_port_number.”
1. Angular CLI: It will create a workspace folder with the same name as the project, along with configuration files.
1. Open the project with any IDE: You can use Visual Studio Code to open your project.
7.Cardinal Rule: Whenever you modify and save your project, Angular will automatically rebuild the app and reload the page.
Keep in mind that you’ll need some knowledge of HTML, CSS, and JavaScript to start working efficiently with Angular.
