Increasing Access
It's good to keep all of our dependencies updated to their latest versions.
Feature enhancement details
We us the eslint-config-airbnb package to define a lot of our code style rules. We are currently on version 16.1.0. I would like to update this to the latest version 19.0.4. This update changes a lot of rules and introduces LOTS of linting errors into the codebase:
✖ 1321 problems (1320 errors, 1 warning)
273 errors and 0 warnings potentially fixable with the--fixoption.
For each rule, we have 3 options:
- If we don't like the rule: Override the rule in our
.eslintrcconfig to allow the current code. - If we do like the rule: Keep the rule and fix the code (sometimes possible with
lint-fixcommand). - If we do like the rule, but don't want to deal with right away: Adjust the rule in our
.eslintrcto downgrade errors to warnings.
My plan right now is to update the package but add exemptions for all of the rules (option 1).
I don't like to change to much in a single PR so my plan is to address desirable rules (option 2) individually. For example I think that no-useless-catch is a good rule which we should use so I put in PR #2212 to fix the code.
Here are examples of all of the new errors:
