Supabase Monorepo

pnpm 11 + Turborepo monorepo. Requires Node >= 22.13.

Structure

Common Commands

pnpm dev:studio              # run Studio dev server → http://localhost:8082
pnpm dev:docs                # run docs dev server
pnpm dev:www                 # run www dev server
pnpm dev:kb                  # run knowledge base dev server
pnpm test:studio             # Studio unit tests (vitest)
pnpm e2e                     # Studio E2E tests (playwright)
pnpm build --filter=studio   # build Studio
pnpm lint --filter=studio    # lint Studio
pnpm typecheck               # typecheck all packages
pnpm format                  # Prettier write (check: pnpm test:prettier)
pnpm generate:types          # local DB types → supabase/functions/common/database-types.ts
pnpm api:codegen             # platform Management API types → packages/api-types

CI

Every PR must pass typecheck + lint (one workflow), Prettier, and a typos check. Other checks are path-filtered: Studio unit tests/build and the lint ratchet (ESLint warning count must not increase) run on apps/studio/** changes; app-specific test suites run on their own paths.

Never hand-edit generated files: packages/api-types/types/**, **/routeTree.gen.ts, **/__generated__/**, apps/docs/features/docs/generated/**, apps/www/.generated/**, supabase/functions/common/database-types.ts, apps/docs/content/_partials/access-control/scoped_pat_*.mdx (run make -C apps/docs/spec generate.partials.access-control).

Conventions

UI — import from 'ui'; primitives are shadcn/ui-based and exported unsuffixed (Input, Select, Form, …). Use Button — the in-house component and the standard everywhere (a raw shadcn Button_Shadcn_ also exists but is rarely the right choice). Check packages/ui/index.tsx before creating new primitives. Higher-level patterns live in packages/ui-patterns.

Styling — Tailwind only, semantic tokens (bg-muted, text-foreground-light), no hardcoded colors.

Exports — named exports only; default exports are allowed only where a framework requires them (pages/**, app/**, config files — the eslint preset has the exact carve-out list). Lint-enforced across all apps via eslint-config-supabase (severity warn everywhere; hard-enforced in Studio by the lint ratchet).

Language — Use U.S. English everywhere.

Public surfaces — this repo is public: PR descriptions, issues, and code comments are world-readable. Keep internal content out of them: absolute production metrics (event counts, user counts, revenue figures: state percentages, ratios, or relative change instead), internal decision detail (vendor, legal, pricing, or strategy discussions), and competitor names (protocol identifiers such as user-agent strings are fine). Put that context in the Linear issue and link it.

Skills

The skills in .agents/skills/ are the source of truth for conventions — load the relevant ones before working, don't guess:

• copywriting — any user-facing text, anywhere in the monorepo
• pm-the-docs / write-the-docs / edit-the-docs / ask-the-docs / review-the-docs — anything under apps/docs (see apps/docs/CONTRIBUTING.md for the authoring skill model)
• telemetry-standards — PostHog events, packages/common/telemetry-constants.ts
• dev-toolbar-review — packages/dev-tools, packages/common/posthog-client.ts, packages/common/feature-flags.tsx
• safe-sql-execution — any code that builds or executes SQL against user databases
• react-hook-form — writing or modifying any form code, anywhere in the monorepo
• vitest / vercel-composition-patterns — generic unit-testing and React composition references

Studio

Before working on anything in apps/studio, read apps/studio/AGENTS.md if it isn't already in context — it maps Studio tasks to required skills and covers the TanStack Start migration rules.
