The version 0.21.0 is not covered by your current version range.

If you don’t accept this pull request, your project will work just like it did before. However, you might be missing out on a bunch of new features, fixes and/or performance improvements from the dependency update.

It might be worth looking into these changes and trying to get this project onto the latest version of xo.

If you have a solid test suite and good coverage, a passing build is a strong indicator that you can take advantage of these changes directly by merging the proposed change into your project. If the build fails or you don’t have such unconditional trust in your tests, this branch is a great starting point for you to work on the update.

Version 0.23.0 just got published.

Update to this version instead 🚀

Release Notes

v0.23.0

Highlights

• In v0.22.0, we added support for .ts and .tsx extensions by default. This caused a lot of problems for non-TS projects, so it has been reverted pending a better solution.
• The quotes rule is now set to disallow using template literals when you're not using any interpolation. xojs/eslint-config-xo@ea693f3
• Removed the no-use-before-define rule. It has too many false-positives. xojs/eslint-config-xo@1257597

New rules

• require-await
• unicorn/prefer-exponentiation-operator
• unicorn/catch-error-name (See this thread if you're wondering why error is preferred over err)
