Understanding “ng serve disable host check” for Dev

Hey Dev, chances are you’re here because you’re looking for a way to disable Angular CLI’s host checking feature. Well, look no further! In this article, we’ll go in-depth on “ng serve disable host check” and explore its uses, benefits, and potential drawbacks. Let’s dive in!

What is ng serve?

Before we talk about “ng serve disable host check,” let’s first understand what ng serve is. This is a command that allows developers to build and run their Angular application locally. The ng serve command is also used as a way to trigger automatic rebuilds and browser refreshes whenever a change is made to the code. However, this command has a host checking feature enabled by default, which can be disabled by using the “ng serve disable host check” command.

Why would you want to disable host checking?

So why would you want to disable host checking? Well, the answer is pretty simple. By default, Angular CLI runs a security check when you try to run your application on a different host than what is specified in the “host” property of the “angular.json” file. This security feature is there to prevent attackers from running malicious code on your system.

However, if you’re just developing locally and you trust the code you’re running, this security feature can become more of a hassle than a help. This is where “ng serve disable host check” comes in handy.

How to use “ng serve disable host check”

Using “ng serve disable host check” is pretty simple. All you have to do is add the “–disable-host-check” flag to the end of the ng serve command. Here’s an example:

Command
Description
ng serve –disable-host-check
Runs the Angular application with host checking disabled

Once you’ve added the “–disable-host-check” flag, you should see a message that reads “ℹ 「wdm」: Compiled successfully.” This means that the host checking feature has been disabled and you’re free to develop and test your application without any restrictions.

Are there any drawbacks to disabling host checking?

While disabling host checking can make your development process easier, it’s worth noting that doing so comes with a potential security risk. Without host checking, anyone can run malicious code on your system if they have access to your network. Therefore, it’s recommended that you only disable host checking when you’re working on a trusted network.
