AlertConfig
AlertConfig
A configuration object for an Admin UI alert.
interface AlertConfig<T = any> {
id: string;
check: (context: AlertContext) => T | Promise<T> | Observable<T>;
recheck?: (context: AlertContext) => Observable<any>;
isAlert: (data: T, context: AlertContext) => boolean;
action: (data: T, context: AlertContext) => void;
label: (
data: T,
context: AlertContext,
) => { text: string; translationVars?: { [key: string]: string | number } };
requiredPermissions?: Permission[];
}
id
stringA unique identifier for the alert.
check
(context: AlertContext) => T | Promise<T> | Observable<T>A function which is gets the data used to determine whether the alert should be shown. Typically, this function will query the server or some other remote data source.
This function will be called once when the Admin UI app bootstraps, and can be also
set to run at regular intervals by setting the recheckIntervalMs property.
recheck
A function which returns an Observable which is used to determine when to re-run the check
function. Whenever the observable emits, the check function will be called again.
A basic time-interval-based recheck can be achieved by using the interval function from RxJS.
Example
import { interval } from 'rxjs';
// ...
recheck: () => interval(60_000)
If this is not set, the check function will only be called once when the Admin UI app bootstraps.
isAlert
(data: T, context: AlertContext) => booleanA function which determines whether the alert should be shown based on the data returned by the check
function.
action
(data: T, context: AlertContext) => voidA function which is called when the alert is clicked in the Admin UI.
label
(
data: T,
context: AlertContext,
) => { text: string; translationVars?: { [key: string]: string | number } }A function which returns the text used in the UI to describe the alert.
requiredPermissions
A list of permissions which the current Administrator must have in order. If the current Administrator does not have these permissions, none of the other alert functions will be called.
