Instead of using a service like this one (or Hound) that comments directly on pull requests, we chose to integrate the same tools in our build process with Phare (https://github.com/mirego/phare), a command-line tool we built which runs Rubocop, JSHint, JSCS, etc. and exits with a global status.

If the code has coding style violations, the build breaks. Exactly like it would if we pushed a failing test.

Personally, I’m not a fan of the noise generated by comments about coding style on pull requests.

There's an obvious trade-off here, though. For example, why stop at basic lint-style checks? You could make a static analyzer part of the build process and fail the build when a defect is detected. The trade-off is the same as with growing a test suite that always runs: Over time, your build times increase, and that makes development tedious.

There's a balance to be found between core checks that run at build time, and additional, more extensive checks, which run automatically and asynchronously (!) once a developer believes their changes to be good enough. Both things have their place in a proper software development flow.

+1 for "lint errors fail the build"

If you also add "and any coding style things you care about, you have to make the linter check for", then you don't have to waste any time on that stuff in the pull request.

GitLab B.V. CEO here. Totally agree that lint errors should fail the build instead of commenting. Otherwise all the people /cc't in the pull/merge request get all the hound comments in their email. And the nice thing about Rubocop https://github.com/bbatsov/rubocop is that you can disable tests easily. With GitLab we initially had: 406 files inspected, 1609 offenses detected. But after selecting only the most important checks and a day of fixing we got a green build.

Same for me. I used Hound for a while but it was annoying to see all this comments. So I just added Rubocop check inside `rake test` so build is broken if you have code style issues

I guess the advantage of Linthub over Phare is that it can run on pull requests made by external contributors.

Actually, it does in a certain way. Travis runs builds (tests + Phare) for all pull requests (eg. https://travis-ci.org/mirego/encore/pull_requests) so we know if pull requests made by external contributors "break the build".

This is exactly why we've develop this. To enforce code quality to pull requests and save the repository owners time.
