electron-reloader 
Simple auto-reloading for Electron apps during development
It just works. When files used in the main process are changed, the app is restarted, and when files used in the browser window are changed, the page is reloaded.
Note that it will not work correctly if you transpile the main process JS files of your app, but it doesn't make sense to do that anyway.
Install
$ npm install --save-dev electron-reloader
Requires Electron 5 or later.
Usage
The following must be included in the app entry file, usually named index.js:
try {
require('electron-reloader')(module);
} catch (_) {}
You have to pass the module object so we can read the module graph and figure out which files belong to the main process.
The try/catch is needed so it doesn't throw Cannot find module 'electron-reloader' in production.
API
reloader(module, options?)
module
Type: object
The global module object.
options
Type: object
debug
Type: boolean
Default: false
Prints watched paths and when files change. Can be useful to make sure you set it up correctly.
ignore
Type: Array<string, RegExp>
Ignore patterns passed to chokidar. By default, files/directories starting with a ., .map files, and node_modules directories are ignored. This option is additive to those.
watchRenderer
Type: boolean
Default: true
Watch files used in the renderer process and reload the window when they change.
Setting this to false can be useful if you use a different reload strategy in the rendererer process, like HMR.
Tip
Using it with Webpack watch mode
Just add the source directory to the ignore option. The dist directory is already watched, so when a source file changes, webpack will build it and output it to the dist directory, which this module will detect.
