• [x] Ensures dependencies are up to date for app & node images

@fideloper: you can check it in the dashboard here

Hi!

I'm not sure Dependabot makes sense in context of this repo, but I could be missing something!

Can you explain to me what it would be doing in this configuration? Would it edit Dockerfile's to change what version of packages are installed?

Hey,

Sorry about the late reply, been buried with work.

Once you enable dependabot on this repo, you can check it out in the dashboard app

Right now, with the config file, the Dockerfile inside app & node directories will be checked.

It's just a better & clean way of keeping dependencies up-to-date.
