Charis 13c4b1584c fix,perf(policies search) (#39790)
* fix(policies search): replace useUrlState with nuqs

There is a bug when typing quickly into the search field on the policies
page: because useUrlState naively uses router.replace, which is
asynchronous, the search term can get corrupted, e.g., searching for
"dummy" might end up with a final value of "dum". Switched to nuqs for
better handling.

* perf(policies page): memoize and optimize for projects with many tables

A project with hundreds of tables will have extremely slow search
performance for the policies page, because of heavy rerendering. Made
some optimizations:
- Memoized to reduce rerendering
- Hid filtered-out tables instead of unmounting, so we don't have to
remount when the search is cleared

* refactor(policies page): pass policies info through context

Avoid having a mess of props by creating a PoliciesDataContext to share
policy information.

* cleanup(policies pages): minor code cleanup, no user-facing changes

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
