Understanding ng serve –allowed-hosts for Devs

As a developer, you want to make sure that your applications are running smoothly and accessible to the public. This is where ng serve –allowed-hosts comes in. In this article, we will dive into what this command does and how it can benefit your application’s performance.

What is ng serve –allowed-hosts?

To put it simply, ng serve –allowed-hosts is a command used in Angular to specify a list of hosts that are allowed to access your application. When you run the ng serve command, it will start a local server that can be accessed by other devices on the same network. By default, this server only allows connections from localhost. However, when you specify –allowed-hosts, you can add additional hosts to that list.

This is particularly useful when you are working in a team environment, and multiple developers need to access the same application. Instead of sharing your localhost IP address, you can specify the IP address of the machine you want to share the application with.

How to use ng serve –allowed-hosts?

Using ng serve –allowed-hosts is relatively simple. All you need to do is add the –allowed-hosts flag followed by the host or list of hosts you want to allow. For example:

ng serve --allowed-hosts 192.168.1.100

This command would allow the IP address 192.168.1.100 to access your application. You can also specify multiple hosts by separating them with commas.

ng serve --allowed-hosts 192.168.1.100,192.168.1.101

What are the benefits of using ng serve –allowed-hosts?

There are several benefits to using ng serve –allowed-hosts. One of the biggest advantages is that it allows you to work collaboratively with your team without having to share your localhost IP address. This can help to prevent conflicts and make it easier to manage the application’s performance.

Additionally, using –allowed-hosts can help to improve the security of your application. By specifying the hosts that are allowed to access the application, you can prevent unauthorized access and reduce the risk of security breaches.
