## 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? Feature, bug fix. Part 3 of 6 in a stack that splits the library redesign into reviewable pieces. ## What is the current behavior? An agent can already fetch any guide as Markdown, but has no way to find out what guides exist: the entry point is a rendered React page. The exporter also fails quietly in ways that ship wrong output rather than failing the build: - An unknown component silently unwraps to its children, so a component rename drops its rendered content. - A registry item that cannot be read produces a page with no file listing. - A link to a missing page produces a 404 URL. - An unrecognized install framework produces a plausible command for the wrong CLI. - Only absolute `/library/docs` links are rewritten, so in-page anchors and sibling links break in the export. ## What is the new behavior? `/library` negotiates Markdown the same way the guides do — `Accept: text/markdown`, or an explicit `/library/index.md` — and returns a categorized catalog with every block, its description, its framework variants, and a link to each guide's Markdown. `config/library.ts` is the single catalog description the generator reads, and a test ties it to the content directory in both directions: a guide cannot be added without a catalog entry, or listed without a guide. Each quiet failure above now throws, and links resolve against the page they appear on and are checked against the set of published documents. ```bash curl -H 'Accept: text/markdown' https://supabase.com/library ``` ## Additional context `config/library.ts` also carries the category and preview metadata the redesigned homepage consumes in the last PR of the stack; here it is exercised by the Markdown index and its test. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Added a browsable library catalog covering categories, blocks, starter apps, and supported frameworks. - Added Markdown versions of the library homepage and documentation for compatible tools and workflows. - Added framework-aware links and expanded registry information, including dependencies and source details. - Markdown requests now work for the homepage and documentation, while browser requests continue receiving HTML. - **Bug Fixes** - Improved document link handling, metadata validation, slug consistency, and detection of duplicate or missing documentation entries. - **Tests** - Added coverage for catalog routes, Markdown generation, homepage negotiation, document parsing, and framework-specific links. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Claude Opus 5 <noreply@anthropic.com> Co-authored-by: Ivan Vasilov <vasilov.ivan@gmail.com>

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.
- 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.
- Envoy is a cloud-native, high-performance edge and service proxy.
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.
