suggestion: instead of throwing on the first undefined check, this could collect all the undefined checks and throw an error for all of them. would prevent a user playing error whackamole
There was a problem hiding this comment.
thought: this would crash the app at startup right? while we'd hope that would be caught by users in local dev, there's still a chance it could creep through to review/staging apps. maybe a safer alternative would be to output a permanently-failing check for undefined checks?

This is probably a new major semver.
@andygout observed in Financial-Times/next-newsletter-signup#434 that when you pass in a check with type
textthe check just silently doesn't show up. That is apparently intentional (at least according to n-health) but I think it's silly behaviour. Thanks Andy!This change makes n-health throw an error whenever it's told to run a check with a type that it doesn't understand.
This PR might be easier to review commit-by-commit to see the test for the previous behaviour. You can add
?w=1to the GitHub diff URL to hide whitespace changes.
