Toast services in Angular Toast component

27 Apr 20247 minutes to read

The Toast component provides a built-in utility function to render the toast with minimal code. The utility function will render the toast without the need of rendering the container element in the DOM where the toast is appended. So that, the toast can now be rendered on the go. The following are the option to render the toast using the utility function.

Show Toast with predefined types

The Toast component support 4 types of predefined toast with essential colors for various situations which can be shown using the ToastUtility.show by just defining the type of the toast without defining any class names. The following options are used as an argument on calling the utility function for predefined types:

Options	Description
content	Specifies the content that can be displayed on the Toast.
type	Specifies the type of the predefined Toasts. The 4 types of predefined toasts are Information, Success, Error, Warning
timeOut	Specifies the Toast display time duration on the page in milliseconds. Once the time expires, Toast message will be removed. Setting 0 as a time out value displays the Toast on the page until the user closes it manually.
