Joshen Lim 0b97e0ff86 Joshen/fe 2642 project settings allow to select a replica to power (#43626)
## Context

Related to dashboard scalability
Previous PR: https://github.com/supabase/supabase/pull/42856

Note: Changes are all feature flagged still and I'm still not entirely
convinced with the current UX
Will iterate as as go along, and only make this publicly available when
we're satisfied with the behaviour

Adds a "Dashboard preference" section to the project settings

/>

In which users can then select which database they'd like to use for
read queries run from the dashboard
Note: Everything is local storage for now, but we'd need middleware
support if we want to make this setting persist for all users on the
project

/>

Added a dialog as well to further explain what this implies

/>

## To test

- Choosing a replica in dashboard preferences will only affect the table
editor as thats the only place that's set up so far to use a replica for
read queries (I'll need to follow up for other parts of the dashboard in
subsequent PRs)

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
const ComponentA = ({ sampleProp }: ComponentAProps) => {
  return <div>ComponentA: {sampleProp}</div>
}

export default ComponentA
