Need to delete all bower components and do fresh bower install on every checkout

Question

Every time I checkout a new branch, then switch back to the branch I was working on, I run into a long list of missing module errors in my JS console. The missing modules are all bower components. If I delete my bower_components folder, then do a fresh bower install, everything works again. Why do I have to do this every time I checkout the branch? Thanks.

Answer 1

You can use Git hooks to accomplish this. Check out digital ocean's article on them for a list.

Specifically, I think post-merge and post-checkout are the ones you are interested in.

Git hooks are just simple shell scripts. Place the following into .git/hooks/post-merge and .git/hooks/post-checkout:

#!/bin/sh
rm -rf bower_components/
bower install

Then make sure that the files are executable by running the following:

chmod 755 .git/hooks/post-checkout
chmod 755 .git/hooks/post-merge
