It is a simple method to restart your application.

Features:

- Separate watchers in main and renderer processes.
- No magic, you necessary specify path files.
- You can use hooks before reload.
- Will catch error, if you want.

## Example

First, you should install this package:

```bash
# Yarn
yarn add electron-hot-reload

# NPM
npm install --save electron-hot-reload
```

Next, you should create watchers:

```javascript
import { mainReloader, rendererReloader } from 'electron-hot-reload';
import { app } from 'electron';
import path from 'path';

const mainFile = path.join(app.getAppPath(), 'dist', 'main.js');
const rendererFile = path.join(app.getAppPath(), 'dist', 'renderer.js');

mainReloader(mainFile, undefined, (error, path) => {
  console.log("It is a main's process hook!");
});

rendererReloader(rendererFile, undefined, (error, path) => {
  console.log("It is a renderer's process hook!");
});
```
