On the frontend, we use Preact, which is exactly like React. I don’t know if you’ve ever worked with this JS framework 
Then, on the server side, it’s Node.js + Express + SQLite.
Nothing too complicated, if you follow several React + Node.js/Express tutorials, you should be able to easily get started with Gladys.
Sorry, no I don’t have the message in mind anymore. I just remember that a good old npm i —build-from-source fixed the issue.
It’s been about 10 or 15 days… Cool if Nodemon is in the package.json now.
I listened to the « devs » call, I loved the « full tests » aspect. It turns out that tomorrow I’m attending a conference on JS testing. If I manage to get some applicable info/slides for the project, I’ll try to share a report. It will be about cypress.io in particular. Storybook wasn’t mentioned, it might be interesting to take a look. From what I’ve seen and understood, beyond the testing aspect, it also allows generating a kind of doc/library of existing components:

The conf (to be exact, a lunch talk at my company) was really very interesting, even if not exhaustive on the subject.
Among other things, Cypress was discussed, but also other technologies.

And if you want to test on your side, to see what it looks like, there is a demo repo
Didn’t have time to digest yet, so not much opinion to give, but that gives you something to make your own 
A video recording was made, I will edit this post later to add the link.
