## Summary - `contentlayer2@0.4.6` is unmaintained and drags in a heavy, stale dependency graph (esbuild pinned to 0.17–0.20, mdx-bundler, old `@opentelemetry/core`) that was the recurring source of vuln bumps. - Migrates all three apps that used it — `design-system`, `ui-library`, `learn` — to [Velite](https://velite.js.org), preserving the generated typed `allDocs`/`Doc` collection and the `body.code` + `useMDXComponent` runtime via a small shared local hook. - Same MDX pipeline (remark-gfm, remark-code-import, rehype-slug, rehype-pretty-code w/ Shiki compat + local theme, rehype-autolink-headings, custom `__rawString__`/`__src__`/`__event__`/`__style__` visitors) ported 1:1 into each app's `velite.config.js`. - `learn`'s extra frontmatter fields (`chapterNumber`, `explore`, `courseHero`) are now backed by real Velite/Zod schema types, so the `(doc as any)` casts in `get-next-page.ts` / `get-current-chapter.ts` / the doc page could be dropped. - `next.config.mjs` no longer wraps with `withContentlayer`; since Velite has no Next.js webpack-plugin equivalent, each app's `dev` script now runs `velite dev` and `next dev` in parallel via `npm-run-all`. Ref: [FE-3861](https://linear.app/supabase/issue/FE-3861/migrate-off-contentlayer2-learn-ui-library-design-system-to-shed) ## Test plan - [x] `pnpm build:content` (Velite build) succeeds for all three apps - [x] `pnpm typecheck` passes for all three apps - [ ] Manual smoke test of `pnpm dev` for each app in a browser (docs pages render, TOC, copy-button, code highlighting) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Improvements** * Improved content generation across documentation, learning materials, and the UI library for more consistent pages. * Preserved MDX rendering, navigation, table of contents, course metadata, source previews, and component examples. * Improved consistency when displaying documentation and interactive examples. * Improved application loading by optimizing how interface components are delivered. * **Chores** * Streamlined content compilation and development workflows across the design system, learning area, and UI library. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

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.
