Frontend Masters: Electron (Version 2)

You'll need a recent version of Node.js installed on your computer with administrative access. Yarn is not required, but Electron Forge uses it, so it would be helpful to install beforehand.

Please make sure you're using a supported platform. This is particularly important if you're running Linux.

Important note: If you're using Windows, make sure you're not using the Windows Subsystem for Linux. This will confuse Electron to thinking you're running on a Linux machine when you're really not.

We'll be using working through the following repositories over the course of the workshop:
