#3443

All reviewed changes have been made

• (Do not skip this or your PR will be closed) I deployed the application locally.
• (Do not skip this or your PR will be closed) I have performed a self-review and testing of my code.
• I have included the issue # in the PR.
• I have added i18n support to visible strings (instead of <div>Add</div>, use):

const { t } = useTranslation();
<div>{t('add')}</div>

• I have not included any files that are not related to my pull request, including package-lock and package-json if dependencies have not changed
• I didn't use any hardcoded values (otherwise it will not scale, and will make it difficult to maintain consistency across the application).
• I made sure font sizes, color choices etc are all referenced from the theme. I don't have any hardcoded dimensions.
• My PR is granular and targeted to one specific feature.
• I ran npm run format in server and client directories, which automatically formats your code.
• I took a screenshot or a video and attached to this PR if there is a UI change.

It's getting there! Some more mostly maintenance related changes, please have a look at my comments. Thank you!

Looks pretty good, I think just a naming convention issue and we should be good here.

[akashmannil]

Thanks for the suggestions. made changes to reflect naming convention changes. Also,

• Moved flex layout props from sx to native Grid props
• Removed nullish coalescing — introduced a PageSpeedCheck interface with required fields to guarantee the type
• Cast latestCheck as PageSpeedCheck since pagespeed monitors always have these values

[ajhollid]

Mostly good, major issue with the TimescaleDB implementation though, please be sure to review and actually test that.

We should avoid the cast to PageSpeedCheck as well since it's type is narrower than Check. Casting to PageSpeedCheck type makes invalid assumptions about what data is present in a Check object.
