Expo Stripe Payments with Supabase Functions

This is a Expo React Native Supabase example app, showing how to process payments with Supabase Functions for authenticated customers.

Setup

Create new Supabase project

• Create a new Supabase project
• Navigate to the Auth settings and turn off the toggle next to "Enable email confirmations". (Note: this is only for testing. In production please enable this setting!)
• Navigate to the SQL Editor and run the SQL from the schema.sql file.

Setup env vars

• Set up env vars for Supabase Functions:
  • cp .env.example .env
  • Fill in your Stripe API keys from https://stripe.com/docs/development/quickstart#api-keys
• Set up env vars for the Expo app:
  • cp app/.env.example app/.env
  • Fill in your public Supabase keys from https://app.supabase.io/project/_/settings/api

Supabase Edge Functions

Supabase Edge Functions are written in TypeScript, run via Deno, and deployed with the Supabase CLI. Please download the latest version of the Supabase CLI, or upgrade it if you have it already installed.

Develop locally

• Run supabase start (make sure your Docker daemon is running.)
• Run supabase functions serve --env-file .env payment-sheet
  • NOTE: no need to specify SUPABASE_URL and SUPABASE_ANON_KEY as they are automatically supplied for you from the linked project.
• Run the Expo app in a separate terminal window:
  • cd app
  • yarn
  • yarn start or yarn ios or yarn android
• Make some test moneys 💰🧧💵
• Stop local development
  • Kill the "supabase functions serve watcher" (ctrl + c)
  • Run supabase stop to stop the Docker containers.

Deploy

• Generate access token and log in to CLI
  • Navigate to https://app.supabase.io/account/tokens
  • Click "Generate New Token"
  • Copy newly created token
  • run supabase login
  • Input your token when prompted
• Link your project
  • Within your project root run supabase link --project-ref your-project-ref
• Set up your secrets
  • Run supabase secrets set --env-file .env to set the env vars from your .env file.
  • You can run supabase secrets list to check that it worked and also to see what other env vars are set by default.
• Deploy the function
  • Within your project root run supabase functions deploy payment-sheet
• In youre ./app/.env file remove the SUPA_FUNCTION_LOCALHOST variable and restart your Expo app.

👁⚡️👁

\o/ That's it, you can now invoke your Supabase Function via the supabase-js and supabase-dart client libraries. (More client libraries coming soon. Check the supabase-community org for details).
