https://linear.app/unleash/issue/2-758/add-variant-improve-the-flow
### Variants form
- Fix variants edit form to follow natural tab order;
- Update variants form UI to new design with multiple improvements and
fixes, including a sticky header;
- New variants are now added at the bottom of the edit form instead of
at the top, with a smooth scroll and focus;
### Change requests
- On the variants diff, use variant names instead of index;
- Use an object-based diff logic (instead of array-based) for cleaner
diffs on variants (thanks @thomasheartman !);
- Display a table with the new variants data and display the diff on a
`TooltipLink`;
- Adapt strategy CR changes to the new `TooltipLink` logic for
consistency;
### Other
- `TooltipLink` and `Badge` components are now tab-selectable;
- Small enhancements, refactors and improvements;

## About the changes
This is based on @nunogois suggestion to split the build in two, so we
don't build the frontend every time we run `yarn`
e2e frontend tests were forced to run by modifying frontend/README.md
### Important files
Some github actions had to be updated to also build the frontend. The
Dockerfile building our docker image was also looked into but it should
work as is
## Discussion points
This is a potentially risky operation as we might overlook something
that requires building the frontend which might lead to invalid builds.
We need to make sure when we do this we don't have any release planned.

Assume `undefined` instead of `null` for project in terms of interfacing
with segments: If the `project` field is not present, that means that it
is not set, which means we're dealing with a "global" segment. If we
want to unset `project` and make a segment global, we simply don't send
the `project` property on our PUT method.

~~Should we handle this on the store layer instead~~? 🤔
Fixing this on the store layer. Effectively, frontend is able to send
`project: null` and even if that gets magically converted to `""` it's
OK since we're covering that use case on the store layer. Backend
response will be `project: null` as well, so it should be consistent.
Project scoped stickiness

## About the changes
This enables strictNullChecks which will give us nice hints in our IDEs
to avoid introducing more and hopefully will encourage us to fix some of
the existing problems.
Also:
1. The compiler explicitly ignores these errors
2. The "null checks action" still verifies we're not introducing new
ones.
The combination of these two things should help us to reduce the number
of nulls
For testing that the action still works (cause it was modified), [a
commit](5c4b818d1a)
was added introducing a bunch of null check errors:
https://github.com/Unleash/unleash/actions/runs/4364648191/jobs/7632224720
### What
This patches two very subtle bugs in the proxy repository that cause it
to never actually stop polling the db in the background
## Details - Issue 1
We've recently started to get the following output when running `yarn
test`:
` Attempted to log "Error: Unable to acquire a connection
at Object.queryBuilder
(/home/simon/dev/unleash/node_modules/knex/lib/knex-builder/make-knex.js:111:26)`
This seems to occur for every test suite after running the proxy tests
and the full stack trace doesn't point to anything related to the
running tests that produce this output. Running a `git bisect` points to
this commit:
6e44a65c58
being the culprit but I believe that this may have surfaced the bug
rather than causing it.
Layering in a few console logs and running Unleash, seems to point to
the proxy repository setting up data polling but never actually
terminating it when `stop` was called, which is inline with the output
here - effectively the tests were continuing to run the polling in the
background after the suite had exited and jest freaks out that an async
task is running when it shouldn't be. This is easy to reproduce once the
console logs are in place in the `dataPolling` function, by running
Unleash - creating and deleting a front end token never terminates the
poll cycle.
I believe the cause here is some subtlety around using async functions
with timers - stop was being called, which results in the timer being
cleared but a scheduled async call was already on the stack, causing the
recursive call to resolve after stop, resurrecting the timer and
reinitializing the poll cycle.
I've moved the terminating code into the async callback. Which seems to
solve the problem here.
## Details - Issue 2
Related to the first issue, when the proxy service stops the underlying
Unleash Client, it never actually calls destroy on the client, it only
removes it from its internal map. That in turn means that the Client
never calls stop on the injected repository, it only removes it from
memory. However, the scheduled task is `async` and `unref`, meaning it
continues to spin in the background until every other process also
exits. This is patched by simply calling destroy on the client when
cleaning up
## The Ugly
This is really hard to test effectively, mostly because this is an issue
caused by internals within NodeJS and async. I've added a test that
reads the output from the debug log (and also placed a debug log in the
termination code). This also requires the test code to wait until the
async task completes. This is horribly fragile so if someone has a
better idea on how to prove this I would be a very happy human.
The second ugly part is that this is a subtle issue in complex code that
really, really needs to work correctly. I'm nervous about making changes
here without lots of eyes on this
