onError

Partially-applied guarded factory: bind an onError callback up front and reuse the resulting decorator across many service methods or composables.

Importing

import { onError } from '@basmilius/common';

Usage

import { onError, useService } from '@basmilius/common';
import { OrderService } from '@/services/OrderService';
import { snackbar } from '@/lib/snackbar';

const handle = onError<(fn: Function) => Function>(err => {
    snackbar.error(err.message);
});

const orders = useService(OrderService, handle);

Because the factory returns a wrapper compatible with useService's Wrap signature, you can pass it as one of the wrap arguments. Internally it delegates to guarded(fn, onError), so any wrapped function gains the same behaviour — 403 becomes ForbiddenException, unsanctioned requests become UnauthorizedException, and arbitrary errors trigger your callback before being rethrown as HandledException.

Type signature

declare function onError<T extends Function>(
    onError: (err: Error) => void
): T;
