Hey, Listen!

Dev-ex warning functions with added childhood flashbacks

Hey, Listen! provides simple versions of the popular warning and invariant dev-experience functions.

The library checks against process.env.NODE_ENV to minify away messages in production.

warning

import { warning } from 'hey-listen';
