runBefore

Build a function decorator that runs a side effect before invoking the wrapped function. Useful as a wrapper for useNavigate or useService when you need to reset analytics, focus, scroll positions or other transient state on every call.

Importing

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

Usage

import { runBefore, useNavigate } from '@basmilius/common';

const trackNavigation = runBefore<(fn: any) => any>(() => {
    console.log('navigation start');
});

const {push} = useNavigate(trackNavigation);

The factory returns a wrapper that, given a function, returns a new function which calls before() first and then forwards the arguments to the original.

Type signature

declare function runBefore<T extends Function>(before: () => void): T;
