Credentials

Supabase Storage exposes an S3-compatible API at https://<project-ref>.storage.supabase.co/storage/v1/s3, signed with S3 Access Keys scoped to a Supabase project (not your anon or service_role JWT).

​
1. Create an S3 access key

  1. Open the Supabase dashboard and pick your project.
  2. Storage -> Settings -> S3 Access Keys.
  3. New access key -> scope to the bucket(s) you want Mirage to mount.
  4. Copy the Access key ID and Secret access key, the secret is shown once.

​
2. Note the project reference and region

  • Project reference is in the dashboard URL: https://supabase.com/dashboard/project/<project-ref>.
  • Region is the region you selected when creating the project. Supabase requires a region string for SigV4 signing even though it is metadata only.

​
3. Set Environment Variables

# .env.development
SUPABASE_BUCKET=my-bucket
SUPABASE_REGION=us-east-1
SUPABASE_PROJECT_REF=abcdefghijklmnop
SUPABASE_ACCESS_KEY_ID=...
SUPABASE_SECRET_ACCESS_KEY=...
Supabase requires path-style S3 URLs. The Mirage resource sets forcePathStyle: true automatically when you pass project_ref.
For Python configuration, see the Python Supabase Resource guide. For Node and browser wiring, see the TypeScript Supabase Setup guide.
