I'm going to use this to ignore the build assets folder.

The next thing I'll do is I'm going to define a files property here. You should basically follow this format with com.your organization name.your product name. You should not change this once it's been set. Basically, these IDs are used to identify your application to the operating system. If those words don't mean anything to you, that's OK. On Mac, this uses the CF bundle identifier, and on Windows, it's the application user model ID.

First thing we have to define is our app ID. Let's go down here, and let's create a build property. You can use the company name or your name here. Also, make sure the author field is filled out, because that'll be visible to your users when they inspect your package. The reason to use product name is that it allows you to use spaces, which NPM won't allow in the name property. Electron-builder will use the name property if product name is not defined. I'm going to call my product Hello World. First thing we want to do is let's define an extra field here, product name. Electron-builder basically takes a JSON config from your package.json, and packages your application for Mac, Windows, or Linux.
