The canonical, machine-readable record of which features each official Supabase client SDK implements.
See the codeShared tooling and specifications for the Supabase client SDKs. This repository is a lightweight monorepo: each project lives as a flat sibling under packages/, with a single toolchain per package and no monorepo build tooling on top.
[!IMPORTANT] Only repository collaborators can open pull requests here.
See the full notice at the top of CONTRIBUTING.md.
| Package | Toolchain | What it is |
|---|---|---|
packages/capability-matrix | TypeScript | The canonical feature registry for all Supabase client SDKs: capability YAML data, per-feature specs, JSON Schema, validator, and site generator. Renders supabase.github.io/sdk. |
packages/dart-symbol-extractor | Dart | Public API symbol extractor for Dart SDKs, used by the Dart compliance workflow. |
packages/go-symbol-extractor | Go | Public API symbol extractor for Go SDKs, used by the Go compliance workflow. |
packages/postgrest-typegen | TypeScript | Introspects a PostgreSQL schema into the GeneratorMetadata contract and generates PostgREST types for TypeScript, Go, and Python. |
packages/typegen | TypeScript | Language registry for supabase gen types --lang: maps each language to its generator (in-process or an external tool) so new languages need no CLI change. |
packages/ # One directory per project (flat siblings, one toolchain each)
.github/ # CI workflows and composite actions, including the reusable
# SDK compliance workflows consumed by the SDK repos
The workflow and action paths under .github/ are a public interface: SDK repos reference supabase/sdk/.github/workflows/validate-sdk-compliance-<language>.yml, sync-sdk-compliance.yml, and the sdk-compliance-* composite actions. Those file names and locations are stable.
If you are here to opt an SDK into compliance validation, or to update which features your SDK supports, see the capability-matrix README.
See CONTRIBUTING.md. Run each package's own toolchain from its directory:
cd packages/capability-matrix && bun install && bun test
cd packages/dart-symbol-extractor && dart pub get && dart test
cd packages/go-symbol-extractor && go test ./...
