abbac3b852 refactor(library): resolve registry dependencies from one source of truth (#50367)
## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Refactor, bug fix.

Part 1 of 6 in a stack that splits the library redesign into reviewable
pieces. This one is the foundation the rest build on and has no visual
change.

## What is the current behavior?

Three build steps each reimplement "where does this registry file land
in the user's project": `process-registry`'s `getDefaultPath`,
`registry/utils`' `uniqBy` on `file.path`, and the Markdown exporter.
They disagree, which produces real bugs:

- A Vue block whose files come from `node_modules/@supabase/vue-blocks/`
keeps its package path, so the installer writes the package folder into
the user's project.
- `registryItemAppend` builds its `docs` string from `(item.docs,
items.flatMap(...))` — a comma expression, so the item's own docs are
discarded.
- A name collision between a block file and its client's file silently
keeps one of the two.
- Install commands guess the CLI family from substrings in the item
name, so `infinite-query-composable` — a Vue block with neither "vue"
nor "nuxtjs" in its name — gets the React CLI.
- Production Vue installs use `@supabase/<name>`, but the `@supabase`
namespace is registered with shadcn, not shadcn-vue.
- `build:registry`, `build:content`, `build:markdown` and `build:llms`
run in parallel, but the last three read `public/r`.

## What is the new behavior?

`lib/registry-resolution.ts` owns installed-path derivation, first-party
dependency naming, deduplication, and cycle detection, and every
consumer calls it. `build-registry` validates the whole registry against
shadcn's schema and resolves every item, so a broken reference fails the
build instead of shipping. `clean-registry` throws rather than logging
past a failure.

Pages declare their install `framework` explicitly instead of it being
inferred, and production Vue installs use the absolute registry URL.

The build steps are serialized behind `build:prepare`, and a new
`library-tests.yml` workflow runs the library's tests, checks the
generated registry is committed, and builds the app.

## Additional context

Regenerated registry artifacts are the mechanical result of the
resolution fix — the Vue client items and the OAuth consent items that
gained their client's docs.

title: Social Authentication
description: Social authentication block for Nuxt.js
---
<BlockPreview name="social-auth/auth/login" />
<Callout className="mt-4">
The block is using Github provider by default, but can be easily switched by changing a single
parameter.
</Callout>
## Installation
<BlockItem
name="social-auth-nuxtjs"
description="All needed components for the social auth flow"
framework="vue"
/>
## Folder structure
This block assumes that you have already installed a Supabase client for Nuxt from the previous step.
<RegistryBlock itemName="social-auth-nuxtjs" />
## Usage
Once you install the block in your Nuxt.js project, you'll get all the necessary pages and components to set up a social authentication flow.
### Getting started
After installing the block, you'll have the following environment variables in your `.env.local` file:
```env
NUXT_PUBLIC_SUPABASE_URL=
NUXT_PUBLIC_SUPABASE_PUBLISHABLE_KEY=
```
- If you're using supabase.com, you can find these values in the [Connect modal](https://supabase.com/dashboard/project/_?showConnect=true&connectTab=frameworks&framework=nuxtjs&using=supabasejs) under App Frameworks or in your project's [API settings](https://supabase.com/dashboard/project/_/settings/api).
- If you're using a local instance of Supabase, you can find these values by running `supabase start` or `supabase status` (if you already have it running).
### Setting up third party providers
We support a wide variety of social providers that you can use to integrate with your application. The full list is available [here](https://supabase.com/docs/guides/auth/social-login).
This block uses the PKCE flow with GitHub as the provider. To switch providers, just update the `provider` field in the `supabase.auth.signInWithOAuth` call. Enable the provider you want to use under [Auth Providers](https://supabase.com/dashboard/project/_/auth/providers) in the Supabase Dashboard and add the necessary credentials.
### Setting up routes and redirect URLs
1. Set the site URL in the [URL Configuration](https://supabase.com/dashboard/project/_/auth/url-configuration) settings in the Supabase Dashboard.
1. Update the redirect paths in `login-form.vue` to point to your app’s logged-in routes. Our examples use `/protected`, but you can set this to whatever fits your app.
1. Visit `http://your-site-url/auth/login` to see this component in action.
### Combining social auth with password-based auth
If you want to combine this block with the password-based auth, you need to:
- Copy the `handleSocialLogin` function into the password-based `login-form.vue` component and bind it to a "Login with ..." button.
- Copy the `@/server/routes/auth/oauth.ts` in your app under the same route.
