Chris StocktonandChris Stockton 8a4bca34a7 feat: add documentation and UI integration for Before User Created hook (#36567)
* feat: add documentation and UI integration for Before User Created hook

- Added new guide: `before-user-created-hook.mdx`, documenting usage, inputs,
  outputs, and multiple complete examples for HTTP and SQL.
- Updated navigation menu and hook index table to include the new hook.
- Hook is now listed as available on Free and Pro plans.

Studio changes:
- Registered `Before User Created` hook in `hooks.constants.ts` with proper
  title, slug, and configuration keys.
- Enabled Docs button linking to hook guide in both `CreateHookSheet` and `HookCard` components.
- Extended hook listing page to support docs access via `secondaryActions`.

This hook allows developers to intercept and reject user creation across all
flows (email/password, OAuth, SSO, SAML, anonymous) - enabling custom signup
logic like domain allowlists, geofencing, or account gating.

* fix: add subnet to mdx lint allowed list

* fix: incorporate feedback and spelling changes

* feat: add allow/deny domain and CIDR examples to before-user-created hook

This commit enhances the documentation for the before-user-created auth hook:
- Adds production-ready SQL examples for blocking or allowing signups by email domain (signup_email_domains) and IP address or CIDR (signup_networks)
- Introduces enum-based classification (allow vs deny) for both domain and network restrictions
- Adds full migration-style snippets for easy copy/paste into Supabase SQL Editor
- Includes updated HTTP examples that delegate to Postgres functions via Supabase client rpc()
- Adds environment setup guidance and edge function scaffolding

* fix: pnpm format

Community & Support

  • Community Forum. Best for: help with building, discussion about database best practices.
  • GitHub Issues. Best for: bugs and errors you encounter using Supabase.
  • Email Support. Best for: problems with your database or infrastructure.
  • Discord. Best for: sharing your applications and hanging out with the community.

How it works

Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.

Architecture

Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.

Architecture

  • Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
  • Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
  • PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
  • GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
  • Storage a RESTful API for managing files in S3, with Postgres handling permissions.
  • pg_graphql a PostgreSQL extension that exposes a GraphQL API.
  • postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
  • Kong is a cloud-native API gateway.

Client libraries

Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
