Updating to work with Glitch or modern frameworks?

I've been revisiting slowtext and have been flummoxed on how to get it to run someplace like Glitch.com. So much has changed on the backend development side in the past 8 years! For reference, this is the standard Hello World Node/express server that Glitch sets up: https://glitch.com/edit/#!/frosted-wind-trout

Any tips would be appreciated!

Start by comparing slowtext's current setup with the linked Glitch Hello World Node/Express server. The issue names no files or tests; done would mean agreeing on a modern-framework or Glitch-compatible setup and demonstrating that slowtext runs there.
