Deploying Supabase Application

Deploying a Supabase application

Overview

Deploy backend changes with Supabase GitHub integration: connect Git in the dashboard, then merge to the production branch to apply migrations and deploy declared Edge Functions. No supabase link or manual db push for the default workflow.

Configure secrets and auth in the Supabase dashboard after deploy.

Agent workflow

Run these steps in order. Works wherever the agent can read and write repository files.

Steps

1. Discovery — Locate the Supabase root (config.toml + migrations/), dashboard working directory, production branch, declared Edge Functions, and storage buckets. Ask the user when multiple candidates exist. Default production branch to main only when repo convention is obvious. Follow discovering-supabase-root.md.

2. Validate locally — From the Supabase root, before first connect:

   supabase db start
   supabase db reset --local   # or: supabase migration up --local
   supabase db lint
   

   If Edge Functions exist, run project-specific checks (e.g. deno check, deno test under functions/). Fix errors before connecting GitHub or merging to the production branch.

3. Document dashboard settings — User connects Git in Project Settings → Integrations → GitHub. Provide a filled-in table from configuring-github-integration.md:

   Setting	Value
   Git repository	User selects repo
   Working directory	Discovered Supabase root path
   Production branch	User's branch
   Deploy to production	Enabled

4. Post-connect verification — After the user enables integration and merges to the production branch:

   • Confirm deploy succeeded in the Supabase dashboard
   • Run project-specific smoke checks for schema or function behavior changes

   First merge to the production branch populates a new remote project. Troubleshooting: troubleshooting-deployment.md.

Decision tree

Deploy Supabase backend?
├─ Locate config.toml + migrations/ → working directory for dashboard
├─ Migrations apply + db lint pass locally?
│  └─ No → fix before connect or merge
├─ User connects GitHub integration + enables Deploy to production
└─ Merge to production branch → verify in dashboard
