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.

```bash
npm install hey-listen
```

### Yarn

```bash
yarn add hey-listen
```

## Usage

### `warning`

```javascript
import { warning } from 'hey-listen';

```

### `invariant`

```javascript
import { invariant } from 'hey-listen';

invariant(false, 'Error message'); // throws "Error message"
```
