Ivan Vasilov 56de26fe22 chore: Migrate the monorepo to use Tailwind v4 (#45318)
This PR migrates the whole monorepo to use Tailwind v4:
- Removed `@tailwindcss/container-queries` plugin since it's included by
default in v4,
- Bump all instances of Tailwind to v4. Made minimal changes to the
shared config to remove non-supported features (`alpha` mentions),
- Migrate all apps to be compatible with v4 configs,
- Fix the `typography.css` import in 3 apps,
- Add missing rules which were included by default in v3,
- Run `pnpm dlx @tailwindcss/upgrade` on all apps, which renames a lot
of classes
- Rename all misnamed classes according to
https://tailwindcss.com/docs/upgrade-guide#renamed-utilities in all
apps.

Directives

Directives are a custom feature of the Supabase docs content system, which allows you to extend MDX to provide custom functionality.

Why not a React component?

MDX supports React components, and that is the preferred way to add new features. If your use case is supported by a React component alone, use that instead.

Custom directives are used to implement features that need low-level parse or compile-time control over the MDX AST.

Syntax

We reserve a special syntax for directives, which start with a $ sign. For example:

<$CodeSample />

This syntax was chosen because it is both:

  • Sufficiently standard to be supported by MDX parsers without needing to build a custom extension.
  • Sufficiently uncommon to avoid collisions with other React components used in docs.
