Supabase Test

A friendly playground for building and validating Supabase Row‑Level Security (RLS) using LaunchQL. It includes real‑world examples, migrations, and a comprehensive test suite you can run locally.

Features

• Policy‑driven examples for users, products, storage, realtime, and functions
• Supabase CLI local stack for zero‑setup Postgres
• Jest‑based tests that exercise RLS behavior end‑to‑end
• Modular schema packages you can reuse and extend

Quick start (tl;dr)

# bring up a local supabase stack
npx supabase init
npx supabase start

# install deps and run all package tests
pnpm install

# if your env needs explicit pg vars, export these:
export PGPORT=54322
export PGHOST=localhost
export PGUSER=postgres
export PGPASSWORD=postgres

# run every package’s tests
pnpm test

getting started (step by step)

this section will walk through everything slowly, from installing tools to running focused tests and exploring the schemas.

• step 1: install prerequisites (node, pnpm, supabase cli)
• step 2: initialize supabase and confirm services are healthy
• step 3: configure pg env vars if your shell needs them
• step 4: run migrations or package deploys as needed
• step 5: run tests (full suite and targeted)
• step 6: inspect policies and iterate

repository layout

• packages/supabase: supabase‑focused sql, tests, and helpers
• packages/rls-demo: demo extension showcasing rls with users/products

scripts you’ll use often

# run the whole workspace test suite
pnpm test

Adding a package using lql

Requirements

• Node.js 20+
• pnpm 10+
• Supabase CLI 2+

troubleshooting

• if pnpm test can’t reach postgres, confirm supabase services are running and the PG* env vars match the port printed by npx supabase start
• if ports are busy, stop old containers or pass a different port to supabase
• node version mismatches can cause odd errors; use node 20+
