How To Change Startup Component In Angular

Changing the startup component in Angular can be a crucial step in customizing and optimizing your application. Personally, I’ve encountered scenarios where I needed to change the default startup component, and understanding how to do this was a game-changer for me. In this article, I’ll guide you through the process of changing the startup component in Angular and provide some personal insights along the way.

Understanding the App Module

The first step in changing the startup component is to understand the structure of the app module. The AppModule is the entry point to your Angular application and is where you configure the initial components, providers, and directives.

Locating the Bootstrap Array

Within the AppModule, there is a bootstrap array that specifies the root component to bootstrap when the application starts. By default, this is usually set to the AppComponent.

Changing the Startup Component

To change the startup component, simply replace the existing component reference with the new component that you want to set as the startup component. This can be any component within your application.

Code Example

Here’s an example of how the bootstrap array looks in the AppModule after changing the startup component to NewStartupComponent:

bootstrap: [NewStartupComponent]


Changing the startup component in Angular is a simple yet powerful customization that can have a significant impact on the behavior of your application. By understanding the structure of the AppModule and the bootstrap array, you can easily modify the startup component to suit your specific requirements.
