Reduce git repository size

Question

I tried looking for a good tutorial on reducing repo size, but found none. How do I reduce my repo size...it\'s about 10 MB, but the thing is Heroku only allows 50 MB and I\

Answer 1

In my case, I pushed several big (> 100Mb) files and then proceeded to remove them. But they were still in the history of my repo, so I had to remove them from it as well.

What did the trick was:

bfg -b 100M  # To remove all blobs from history, whose size is superior to 100Mb
git reflog expire --expire=now --all
git gc --prune=now --aggressive

Then, you need to push force on your branch:

git push origin  --force

Note: bfg is a tool that can be installed on Linux and macOS using brew:

brew install bfg
