* Lint rule for unminified errors
Add a lint rule that fails if an invariant message is not part of the
error code map.
The goal is to be more disciplined about adding and modifiying
production error codes. Error codes should be consistent across releases
even if their wording changes, for continuity in logs.
Currently, error codes are added to the error code map via an automated
script that runs right before release. The problem with this approach is
that if someone modifies an error message in the source, but neglects to
modify the corresponding message in the error code map, then the message
will be assigned a new error code, instead of reusing the existing one.
Because the error extraction script only runs before a release, people
rarely modify the error code map in practice. By moving the extraction
step to the PR stage, it forces the author to consider whether the
message should be assigned a new error code. It also allows the reviewer
to review the changes.
The trade off is that it requires more effort and context to land new
error messages, or to modify existing ones, particular for new
contributors who are not familiar with our processes.
Since we already expect users to lint their code, I would argue the
additional burden is marginal. Even if they forget to run the lint
command locally, they will get quick feedback from the CI lint job,
which typically finishes within 2-3 minutes.
* Add unreleased error messages to map
* Use %s in the console calls
* Add shared/warningWithStack
* Convert some warning callsites to warningWithStack
* Use warningInStack in shared utilities and remove unnecessary checks
* Replace more warning() calls with warningWithStack()
* Fixes after rebase + use warningWithStack in react
* Make warning have stack by default; warningWithoutStack opts out
* Forbid builds that may not use internals
* Revert newly added stacks
I changed my mind and want to keep this PR without functional changes. So we won't "fix" any warnings that are already missing stacks. We'll do it in follow-ups instead.
* Fix silly find/replace mistake
* Reorder imports
* Add protection against warning argument count mismatches
* Address review
* use different eslint config for es6 and es5
* remove confusing eslint/baseConfig.js & add more eslint setting for es5, es6
* more clear way to run eslint on es5 & es6 file
* seperate ESNext, ES6, ES6 path, and use different lint config
* rename eslint config file & update eslint rules
* Undo yarn.lock changes
* Rename a file
* Remove unnecessary exceptions
* Refactor a little bit
* Refactor and tweak the logic
* Minor issues
* Inline getTestDocument into test cases
* Remove mention of mock file we do not use
* Remove unused configuration entries
* Move eslint-rules package into the scripts/ folder
