Alaister YoungandAlaister Young b0e31be89a chore(studio): remove dead code found by knip (#49719)
Removes Studio code that nothing imports, as reported by knip. First PR
in a stack of three: this one is pure deletions, #49720 removes the
unused dependencies, #49721 upgrades knip and adds the CI gate so this
doesn't accumulate again.

Every file was verified with a repo-wide grep for its basename, exported
symbols, and string/dynamic imports before deletion — none are reachable
via `next/dynamic`, a barrel file, or a config.

**Removed:**
-
`Billing/Usage/UsageWarningAlerts/{CPU,RAM,DiskIOBandwidth}Warnings.tsx`
(whole directory)
- `DataWarehouse/FormFooterChangeBadge.tsx` (whole directory)
- `Database/Replication/ReplicationDiagram/EmptyReplicationDiagram.tsx`
- `Integrations/Vercel/OrganizationPicker.tsx`
- `QueryInsights/QueryInsightsTable/QueryInsightsTableRow.tsx`
- `hooks/misc/useTrackExperimentExposure.ts`
- `data/ai/{parse-client-code,sql-policy}-mutation.ts`,
`data/misc/parse-query-mutation.ts`,
`data/database/table-check-rls-mutation.ts`
-
`data/notifications/notifications-v2-{archive-all-mutation,summary-query}.ts`
+ their two now-unused keys in `notifications/keys.ts` (`listV2` kept)
-
`data/platform-apps/platform-app-{update,signing-key-delete}-mutation.ts`
- `DateTimeFormats.DATE_ONLY` and the unused
`Notebooks.{MarkdownCell,LogCell,ChartConfig}` types

**Changed:**
- `ReportPadding` no longer has a duplicate default export; its 9
default importers (observability pages) now use the named export

Not removed: `CONSTRAINT_TYPE`'s unused members mirror the closed set of
`pg_constraint.contype` values, so they're documentation rather than
dead code — suppressed narrowly in #49721's knip config instead.

## To test

- `pnpm --filter studio run typecheck` and `lint:ratchet` pass
- Observability pages (`/project/[ref]/observability/*`) still render
with padding — they're the only code touched, via the `ReportPadding`
import change
- Notifications popover still loads and marks-as-read (the removed keys
weren't used for invalidation)

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.
  • 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.
