Everything You Need to Know About ng serve host

Hello, Dev! In this journal article, we will be discussing everything you need to know about ng serve host. This includes what it is, how to use it, and its benefits. Whether you are an experienced developer or a beginner, this article is for you. So, let’s dive in!

What is ng serve host?

Before we dive into the details, let’s first understand what ng serve host is. Simply put, ng serve host is a command that is used to start a local development server for Angular applications.

This server performs several tasks such as compiling the application code, serving the compiled files, and reloading the browser whenever changes are made to the code.

When you run the ‘ng serve’ command, by default the server listens on port 4200. However, with ng serve host, you can change the default host and port to something else entirely.

How does ng serve host work?

When you execute the ‘ng serve host’ command, it first checks whether a configuration file called ‘angular.json’ exists in your project directory. This file contains all the settings for your Angular application including the port and host configuration.

If the ‘angular.json’ file doesn’t exist, ng serve host will look for a file called ‘tsconfig.json’ and use the ‘baseUrl’ setting as the root of the application. If this file doesn’t exist, ng serve host will assume that the root of the application is the current directory.

The server then listens on the configured host and port and compiles the TypeScript files into JavaScript. It also watches for changes to the code and performs live reloading in the browser whenever any changes are detected.

Why use ng serve host?

So, now that you know what ng serve host is and how it works, let’s talk about why you should use it.

The default ‘ng serve’ command is great for getting started with Angular development. However, it has its limitations. For instance, you cannot specify a custom host and port, which can be a problem if you are working on multiple projects simultaneously.

By using ng serve host, you can easily specify a custom host and port for your application. This makes it easy to work on multiple projects simultaneously without any conflicts.

How to use ng serve host

Now that you know what ng serve host is and why you should use it, let’s talk about how to use it. The process is simple and straightforward.

Step 1: Install the Angular CLI

The first step is to install the Angular CLI if you haven’t already. You can do this by running the following command in your terminal:

npm install -g @angular/cli

This command will install the latest version of the Angular CLI globally on your system.

Step 2: Create a new Angular project

The second step is to create a new Angular project. You can do this by running the following command:

ng new my-app

This command will create a new Angular project called ‘my-app’ in a new directory of the same name.

Step 3: Run ng serve host

Once you have created a new Angular project, you can now run ng serve host. The command takes two arguments: the host and the port.

ng serve --host 0.0.0.0 --port 4201

This command will start the development server on the 0.0.0.0 host and the 4201 port.

Advanced usage of ng serve host

Now that you know how to use ng serve host, let’s talk about some advanced usage scenarios.

Changing the default host and port in angular.json

You can also change the default host and port for your Angular application by modifying the ‘angular.json’ file. Here’s how:

1. Open the ‘angular.json’ file in your project directory.
2. Find the ‘serve’ section and modify the ‘host’ and ‘port’ properties as desired.
3. Save the file and run the ‘ng serve’ command.

Using ng serve host with SSL

If you want to use SSL with ng serve host, you can do so by passing the ‘–ssl’ flag along with the ‘ng serve’ command.

ng serve --ssl true --ssl-cert /path/to/cert --ssl-key /path/to/key

This command will start the development server with SSL enabled using the specified certificate and key files.
