Cursive Connections

Dev Setup

From root:

• Create local postgres database, set name to be connections_test and port to 5432 (the default).
• CREATE DATABASE connections_test;
• pnpm install

Frontend:

• cd apps/frontend
• Copy over .env.example into .env and update vars
  • Set NEXT_PUBLIC_API_URL to point to the backend, defaults to http://localhost:8080/api
  • Set BLOB_READ_WRITE_TOKEN to point to vercel blob store
  • Set NEXT_PUBLIC_SUPABASE_URL and NEXT_PUBLIC_SUPABASE_ANON_KEY based on supabase instance
• source .env
• pnpm run dev

Backend:

• In a separate terminal, cd apps/backend
• Copy over .env.example into .env and update vars
  • Set FRONTEND_URL to point to the frontend (for cors), defaults to http://localhost:3000
  • Set DATABASE_URL to point to the database, for local dev this defaults to postgresql://postgres:postgres@localhost:5432/connections_test?schema=public
  • Set AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION, AWS_SES_SENDER_EMAIL to correspond to IAM credentials for AWS Simple Email Service
• source .env
• Run pnpm prisma migrate dev to run db migrations
• Run pnpm prisma generate to generate the prisma client
• pnpm run dev

Testing:

• This is meant to be a mobile browser app. You can either test this on mobile browser by connecting it to localhost or using ngrok/similar service, or test from a desktop web browser using mobile view
• This app does not work in incognito mode
• Make sure you've seeded database with testing UserChip values: pnpm run seed
  • To register, visit: http://localhost:3000/tap?chipId=TEST001 and go through registration flow. TEST002- TEST005 are also available for testing.
• Once logged in, to tap another account there are two steps:
  • Create new account, visit http://localhost:3000/tap?chipId=TEST002 in a different browser
  • To tap a connection, visit http://localhost:3000/tap?chipId=TEST002 from your first browser, where the chipId corresponds to the other existing account
• After a full deletion sometimes old local storage values will still be populating site, visit http://localhost:3000/logout to logout or delete the local storage corresponding to localhost:3000.
• To clear the database, run npx prisma migrate reset from apps/backend. NOTE THIS WILL WIPE YOUR POSTGRES

Testing Secret Values:

• For the email service, AWS_SES_SENDER_EMAIL, AWS_ACCESS_KEY_ID, AWS_REGION, and AWS_SECRET_ACCESS_KEY must be set with target email and key info.
• For the passkey / PSI to work, BLOB_READ_WRITE_TOKEN must be set with secret.

Testing Utilities:

• For dropping test DB: psql, DROP DATABASE connections_test WITH (FORCE);
• To filter requests in Chrome Inspect, use negative filter -.png -.jpg -.jpeg -.gif -.json -.js in Network tab.

Notes:

• API/backend uses null types for interop, client storage uses undefined for storage efficiency - conversions are done with zod.transform
