Alaister YoungandAlaister Young 397965cfae [FE-4186] fix(studio): endless region selector loading for AWS_NIMBUS orgs (#49131)
On the new-project form, the Region select's trigger label and inline
spinner were driven by `isLoadingAvailableRegions` — the `isPending`
state of `useOrganizationAvailableRegionsQuery`. For `AWS_NIMBUS` orgs
that query is permanently disabled (`smartRegionEnabled` is false), and
a disabled query stays `isPending` forever, so the trigger showed
"Loading available regions..." with a spinner indefinitely even though
the default region was actually selected underneath and the form still
worked.

**Changed:**
- The trigger label and spinner now use the provider-aware `isLoading`
(`smartRegionEnabled ? isLoadingAvailableRegions :
isLoadingDefaultRegion`), which the component already used for the
select's `disabled` state and placeholder. For non-Nimbus providers the
two values are identical, so the normal path is unaffected.

## To test

- Emulate a Nimbus deployment locally by setting
`"infra:cloud_providers": ["AWS_NIMBUS"]` in
`apps/studio/hooks/custom-content/custom-content.json`, then open the
new-project form: the Region field should show the default region (name
+ flag) within a moment — not an endless "Loading available regions..."
spinner — and the dropdown should open with the specific-regions list
- Restore the normal provider list and reload: the field should briefly
load, then show smart regions ("General regions") plus specific regions
with Recommended badges, as before
- Toggle High Availability on/off in either config: the selector should
transition between region lists without getting stuck loading

## Summary by CodeRabbit

* **Bug Fixes**
  * Improved loading indicators in the region selector.
* The selector now consistently shows the correct loading state while
regions are being loaded.

Writing components

Where to create your components

  • For components that declare the general structure and layout of a page:
    • /components/layouts/xxx
  • For components that are tightly coupled to a specific interface:
    • /components/interfaces/xxx
  • For components that are meant to be reusable across multiple pages:
    • /components/ui/xxx
  • Note: We're gradually moving files out of the to-be-cleaned folder into the respective folders as we refactor

Component structure

  • If a component has constants and utility methods that are tightly coupled to itself, keep them close to the component and enclose them in a folder with an index.tsx as an entry point
  • Otherwise it can just be a file on its own
  • For example:
    • components/ui
      - SampleComponentA
        - SampleComponentA.tsx
        - SampleComponentA.constants.ts
        - SampleComponentA.utils.ts
        - SampleComponentA.types.ts
        - index.ts
      - SampleComponentB.tsx
      

Template for building components


// Declare the prop types of your component
interface ComponentAProps {
  sampleProp: string
}

// Name your component accordingly — use a named export, not a default export
export const ComponentA = ({ sampleProp }: ComponentAProps) => {
  return <div>ComponentA: {sampleProp}</div>
}
