The library checks against `process.env.NODE_ENV` to minify away messages in production. ## Install ### npm ```bash npm install hey-listen ``` ### Yarn ```bash yarn add hey-listen ``` ## Usage ### `warning` ```javascript import { warning } from 'hey-listen'; warning(false, 'Warning message'); // console.warn "Warning message" ``` ### `invariant` ```javascript import { invariant } from 'hey-listen'; invariant(false, 'Error message'); // throws "Error message" ```
