just-once

Part of a library of zero-dependency npm modules that do just do one thing. Guilt-free utilities for every occasion.

npm install just-once
yarn add just-once

Create a function that can only be invoked once
import once from 'just-once';

const fn = once(() => console.log('hello'));

fn();
// logs 'hello'
fn();
// does nothing
