This skill should be used when user asks to "use supabase-js", "query Supabase database", "supabase auth", "supabase storage", "supabase realtime", "supabase edge functions", or works with the @supabase/supabase-js JavaScript/TypeScript SDK.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Supabase JavaScript SDK Skill
Skill for building applications with the `@supabase/supabase-js` SDK. Covers Auth, Database (PostgREST), Storage, Realtime, and Edge Functions.
The SDK docs at https://supabase.com/docs/reference/javascript are the source of truth. The reference files alongside this skill contain source code and READMEs extracted from the monorepo for quick lookup.
## Setup
```bash
npm install @supabase/supabase-js
```
```typescript
import { createClient } from '@supabase/supabase-js'
const supabase = createClient('https://xyzcompany.supabase.co', 'public-anon-key')
```
For type-safe queries, generate types from your database schema:
```bash
supabase gen types typescript --project-id your-project-id > database.types.ts
```
```typescript
import { createClient } from '@supabase/supabase-js'
import type { Database } from './database.types'
const supabase = createClient<Database>(SUPABASE_URL, SUPABASE_ANON_KEY)
```
## Quick Decision Trees
### "I need to query data"
```
Database query?
├─ Select rows → supabase.from('table').select('*')
├─ Filter rows → .select().eq('col', val) / .gt() / .lt() / .in() / .like()

How to install
mdr add fcakyon/claude-codex-settings/supabase-js@sha256:107f4a950dc6410fThe line at the top of this page pins the label git:20260401.3df87c5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
