https://linear.app/unleash/issue/2-3406/hold-unknown-flags-in-memory-and-show-them-in-the-ui-somehow
This PR introduces a suggestion for a “unknown flags” feature.
When clients report metrics for flags that don’t exist in Unleash (e.g.
due to typos), we now track a limited set of these unknown flag names
along with the appnames that reported them. The goal is to help users
identify and clean up incorrect flag usage across their apps.
We store up to 10 unknown flag + appName combinations, keeping only the
most recent reports. Data is collected in-memory and flushed
periodically to the DB, with deduplication and merging to ensure we
don’t exceed the cap even across pods.
We were especially careful to make this implementation defensive, as
unknown flags could be reported in very high volumes. Writes are
batched, deduplicated, and hard-capped to avoid DB pressure.
No UI has been added yet — this is backend-only for now and intended as
a step toward better visibility into client misconfigurations.
I would suggest starting with a simple banner that opens a dialog
showing the list of unknown flags and which apps reported them.

Did two things:
1. Use basePath to prefix the Unleash repo used with the Unleash
Frontend SDK.
2. Use JSON.stringify as key for useEffect to avoid potential render
loop
Implements client-side validation of constraint values before you can
add them to a constraint.
I've removed the extra server-side validation that used to happen for
each specific constraint, because the surrounding form itself uses
server side validation to check every constraint every time there's a
change. This is what controls disabling the submit button etc.
I wanna make the next PR a bit of a followup cleanup now that it's
clearer what properties we do and don't need.

Adds inputmode='decimal' to input fields with number input. As discussed
on the [GOV.UK
blog](https://technology.blog.gov.uk/2020/02/24/why-the-gov-uk-design-system-team-changed-the-input-type-for-numbers/),
this finds a balance between giving numeric input options to mobile
devices and improving validation / user experience.
They mention this bit in their [design system
guideline](https://design-system.service.gov.uk/components/text-input/#numbers)
> Do not use `<input type="number">` unless your user research shows
that there’s a need for it. With `<input type="number">` there’s a risk
of users accidentally incrementing a number when they’re trying to do
something else - for example, scroll up or down the page. And if the
user tries to enter something that’s not a number, there’s no explicit
feedback about what they’re doing wrong.
I've purposefully not included the `pattern="[0-9]*"` attribute here,
because the browser error messages conflict with our own and have
several drawbacks in terms of accessibility according to Adrian
Roselli's ["Avoid default field
validation"](https://adrianroselli.com/2019/02/avoid-default-field-validation.html).
Instead, the validation here will be part of the validation handling
later.
Also, I've opted for using `decimal` instead of `numeric`, because we
allow you to store decimal values and that inputmode also adds the
decimal separator to the keyboard. As always, however, there's
complications: several languages (including Norwegian) use a comma as a
decimal separator instead of a period, so the keyboard will likely
contain numbers and a comma instead of a period. This is a problem
because JS doesn't recognize "45,6" as a valid number. I've added a
follow-up task to look into this. I thought at first it would just be
expanding the validation, but because it's stored as a string on the
back end and the SDKs presumably parse it, we can't just suddenly allow
commas as decimal separators.
Adds an "add value" with popover input for single-value fields
(numerical and semver operators).
The implementation re-uses the popover from the multi-value constraint
operators, so I've extracted it for re-use.
All current input types:

/>
For the new one, opening the popover when there's a value will
pre-select the value, so you can override it by typing immediately:

/>
Buttons look pretty identical:

## Discussion points
### Input type
I haven't set an input type anywhere on the popover yet. In theory, we
could use input type "number" for numerical inputs and I think it's
worth looking at that, but we don't do in the old implementation either.
I've added a task for it.
### Weird esc handling
This implementation uses a chip for the button/value display for the
single. In almost all cases it works exactly as I'd expect, but closing
the popover with esc moves your focus to the top of `body`.
Unfortunately, this isn't something we can address directly (trust me,
I've tried), but the good news is that this was fixed in mui v6. The
current major is v7, so we probably want to update before too long,
which will also fix this. More info in the MUI docs:
https://mui.com/material-ui/migration/upgrade-to-v6/#chip
I think that for the single value entry, losing focus on esc is a fair
tradeoff because it handles swapping states etc so gracefully. For the
multi-value operators, however, esc is the only way to close the
popover, so losing focus when you do that is not acceptable to me. As
such, I'll leave the multi-value input as a button for now instead.
(It's also totally fine because the button never updates or needs to
change).
