Build failed - preact-material-components & encoding

[thoni56]

This bundle was exactly the combination I was looking for!

Unfortunately I get some build errors:

My package.json contains dependencies to preact-material-components and encoding. I'm just starting out on my electron/preact journey, so I need some handholding here.
