Theme

Expected behavior

The GitHub integration does not obey .gitignore files. This has the side effect of files that should not be in the git repo being committed by Shopify. Examples of this type of file are built assets. The expected behaviour is that any file in a repo's .gitignore file should not be forced back into the repo if it exists in the theme (and not in the repo).

There are numerous community posts reporting the same issue:

Not sure if this is the right place to report this, but I don't see an alternative, so hopefully it ends up with the right team.

Actual behavior

Shopify GitHub integration forces ignored files to be tracked.
