I would also like to add prettier but wanted to keep this PR minimal

Should we merge this now or wait until we have a few more PRs merged; this may need that authors refactor their PRs.

[dblythy]

Your call! It's all auto-fixed anyway so it can wait

[mtrezza]

Then I'd say let's merge a few more larger PRs first

@dblythy I think after merging https://github.com/parse-community/parse-dashboard/pull/1657 this PR should be good to go, we have merged all other larger PRs since Sept 10. The other larger PRs (https://github.com/parse-community/parse-dashboard/pull/1677, https://github.com/parse-community/parse-dashboard/pull/1761) have become stale and it doesn't seem as if they'd be picked up anytime soon unfortunately.

I would still want us to consider whether we need enforcing pre-commit hooks, I personally am not in favor of these for reasons I have mentioned before.
