Backup your GitLab repos to GitHub

GitLab recently decided to silently delete any repositories that hadn't been accessed in the last year. The announcement didn't go over well and they soon caved to public pressure and decided to instead back up inactive repos to object storage instead of unilaterally deleting them. I'm glad they reconsidered, but the experience left me with a bad taste in my mouth, so I decided to look into (relatively) low

// Bootstrap 4 depends on Popper.js
// Popper.js import
