The ESLint config has been updated to v8. The breaking changes are:
* The Prettier rule `quoteProps` has been changed from `consistent` to
`as-needed`, meaning that if one key requires quoting, only that key is
quoted rather than all keys.
* The ESLint rule `no-shadow` has been made more strict. It now
prevents globals from being shadowed as well.
Most of these changes were applied with `yarn lint:fix`. Only the
shadowing changes required manual fixing (shadowing variable names were
either replaced with destructuring or renamed).
The dependency `globalThis` was added to the list of dynamic
dependencies in the build system, where it should have been already.
This was causing `depcheck` to fail because the new lint rules required
removing the one place where `globalThis` had been erroneously imported
previously.
A rule requiring a newline between multiline blocks and expressions has
been disabled temporarily to make this PR smaller and to avoid
introducing conflicts with other PRs.
The beta build currently has a couple of UI elements (the horizontal
logo and the app header) set to "dark mode", even though nothing else
in our UI supports dark mode yet. These styles have been removed. We
should make the entire UI support dark mode all at once at a later
date.
Also the horizontal logo used for beta was named incorrectly; the dark
and non-dark logos were swapped. They have been switched back so that
the logo that ends with `-dark` is for dark mode.
