Angular Serve is a command-line tool that allows developers to run their Angular applications locally for testing and development purposes. In this article, we will take a closer look at the Angular Serve command and how it can help developers streamline their workflow.
Before diving into Angular Serve, you must ensure that you have installed the latest version of Node.js and Angular CLI on your computer. Once you have installed these dependencies, you can open your terminal or command prompt and navigate to the directory where your Angular project is located.
The basic syntax for running Angular Serve is as follows:
ng serve
This command will start the development server and compile your Angular application. By default, the server will listen on port 4200, so you can access your application by navigating to http://localhost:4200 in your web browser.
Angular Serve offers several options that developers can use to customize their build process. For example, you can specify the port on which the server should listen by adding the --port flag:
ng serve --port=8080
You can also specify which environment file to use during the build process by adding the --configuration flag:
ng serve --configuration=production
This will tell Angular Serve to use the environment.prod.ts file instead of the default environment.ts file.
One of the most useful features of Angular Serve is hot module reloading (HMR). With HMR enabled, changes made to your code will be automatically reflected in the browser without the need to manually refresh the page.
To enable HMR, simply add the --hmr flag when running Angular Serve:
ng serve --hmr
Overall, Angular Serve is an extremely useful tool for developers working on Angular applications. By providing an easy-to-use development server with custom build options and hot module reloading, Angular Serve can help developers streamline their workflow and accelerate the development process.
