[Dependencies] Update Emotion 10 to 11 #910

michaeljaltamirano · 2021-04-05T22:58:42Z

What and Why

This PR updates our @emotion dependency to use version 11 instead of version 10. See docs for more details.

Replace all version 10 dependencies with their version 11 equivalents (often with a new namespace, e.g. eslint-plugin-emotion is now @emotion/eslint-plugin)
Run @emotion/pkg-renaming eslint rule (with --fix) as codemod
Remove version 10 TypeScript paths usage in favor of new emotion.d.ts standard
Ensure storybook is compatible with our version 11 usage (since it still relies on version 10 internally)
Fix a babel warning to make an implied setting explicit
Run yarn run test -u to update the snapshots with the new serializer logic.
- Most of the lines of code in this PR are just diffs in snapshot tests. Our Chromatic visual UI tests show no regression, which is the more important signal than already hard-to-read snapshots.
- You can see a trivial example of the diff in src/shared-components/toggle/snapshots/test.tsx.snap, which just replaces the emotion classnames (e.g. emotion-0) with other classnames.
  - In more complex snapshots, the order of the classnames in the stylesheet also changes more significantly, but as mentioned the visual regression tests are our main source of truth for whether or not a change is changing behavior.

Skipped Snapshot Tests

This PR has been so long-standing because there has been a snapshot serialization regression in CI that I've tried long and hard without success to debug. It happens as follows:

Some snapshot tests encounter an issue where usually only for the first snapshot test are the serialized styles in CI different than locally.
- Some tests, like src/shared-components/field/test.tsx, fully failed in CI.
For tests for which only the first test fails, when commenting out the first test, it ends up being the second snapshot that fails.
Even SSHing into the CI build, copying the entire radiance-ui repository from that SSH instance to my local disk, and then running the test suite locally was not able to reproduce the issue.

I'm not sure why I can't find instances of this in CI, but here is a link where you can see the failing snapshots, and see that the issue is that the serialization order is changing very insigificantly, but nothing else: https://app.circleci.com/pipelines/github/curology/radiance-ui/2469/workflows/65276136-7360-4103-9e7e-41dff0a89393/jobs/7590/parallel-runs/0/steps/0-105

UPDATE: I actually ran into this again while trying to reduce the diff to make the PR easier to review, and also to remove all trace of my attempts to work around the issue. Interestingly, just changing the syntax of applying styles conditionally (PR diff, to fix the issue) broke the order of the serialized styles (CI link). This suggests that the fix to the other issues might be similarly more explicitly falsy/nullish handling. One additional test on the Accordion component was not successful, though, so the instances that cause it may be non-obvious.

Ultimately, I decided to skip these snapshot tests entirely. Now that we have visual regression testing, they are already of diminished value. I also kept the non-snapshot tests in the component tests, if present.

Considerations

To make migrations like this in the future earlier, we should consider wrapping css-in-js usage around a helper file that exports the methods we need.
- This applies to other 3rd party libraries moreso than @emotion, since we rely on it so heavily, but doing so would also allow us to more easily experiment with other 3rd party libraries that have no runtime element, like Linaria.

Release Plan

This PR is based to next. After it is merged in, I will cut a beta version of radiance-ui@^22.x.x. I will pull this into my own consumer app for testing, and it can also be pulled into our gatsby pages for testing. This will allow us to:

Merge in minor and patch version changes to radiance-ui@^21.x.x without emotion major version changes blocking in.
Allows us to pull in any patches required after this specific PR to be part of 22.0.0 instead of immediately patching it.

This is a bit risky, because in the past even patch version changes have caused regressions: #136

However we can see if that was just a one-off and not something that happens most of the time, which gives some more flexibility in the compatible versions.

Longer-term we might want a stronger/more explicit strategy for the shared dependencies in our consumer repos.

This reverts commit d9a2b75.

I'm so excited for this! @michaeljaltamirano you got it figured out so soon. I'll take a look sometime soon, but ultimately, I'll leave it up to @chrisq21 to approve as the Gatsby v3 upgrade is now relevant to his cycle project.

src/shared-components/button/style.ts

-
-  &:visited,
-  &:hover {
-    opacity: 1;


So we no longer want to change the opacity and color on visited and hover?

Ah never mind, this makes sense since those values weren’t actually being changed.

Yep, and it seems like the redundant styling, paired with how we apply conditional styles, is part of what is causing the CI issues. 🤷

Oof, nice discovery.

Do you know if this will have any influence on how we use ThemeType on the Gatsby sites?

Specifically here and here

Yep, we no longer need those files (this PR removes those equivalents here). This file will be the new standard: https://emotion.sh/docs/typescript#define-a-theme

This looks good! Thanks for setting up this update so quickly.

We'll be doing a lot of regression testing on the Gatsby V3 update, so I'll let you know if we find any radiance-ui or emotion related issues.

Side-note: I wasn't aware of the Chromatic visual UI tool. That sounds really useful.
