Diagram

Setup environment

1. cp ./dotenv/test.env ./dotenv/.env
2. Include DATABASE_URL

   DATABASE_URL="postgresql://<user>:<password>@<url>:5432/postgres?schema=<scheme>"
   

   Note that you should change appropriate values in user, password, url, scheme fields. Or you can even use other database. More about connection urls

3. Running yarn start will load env from dotenv/.env.

Generate Prisma Client and Nexus

yarn generate

Migration

Init migration

1. Change models in schema.prisma.

   Note that prisma/migrations dir is included in .gitignore in this repo but it should not be ignored in production.

2. Run migration script.

   yarn migrate:dev
   

   Prisma ensure that the db migrates correctly after changing Prisma schema (schema.prisma).

3. Deploy migration to production.

   yarn migrate:deploy
   

   This migrates your local database.

When you've changed your schema.prisma, in your pull request, note that in the readme that the db should be migrated before deploying sourcecode to production.

[2021.05.13] Currently, we don't have any better solution to seamlessly deploy database when sourcecode is merged. This is because we won't let github workflow or anyother workflow to access our database for security reason. We are looking for a better option to run the migration script in Azure side.
