Packaging and distribution

When we worked with File Explorer and NW.js, we used the nwjs-builder tool for packaging our application. The Electron has an even more sophisticated tool--electron-builder (https://github.com/electron-userland/electron-builder). Actually, it builds an application installer. The range of target package formats electron-builder supports is impressive. Then, why not try packaging our application? First, we install the tool:

npm i -D electron-builder 

We add a new script to the manifest--./package.json:

 "scripts": { 
    ...  
    "dist": "build" 
  }, 

We also set an arbitrary ID for the application in field build:

 "build": { 
    "appId": "com.example.chat" 
  }, 
 

We definitely want to provide the application with an icon, so we create the build subdirectory and place their icon.icns for macOS...
