Overview

Seamless automates the deployment process from push to Prod

Seamless's backend is comprised of an Express server connected to a Postgres database through the Prisma ORM. It utilizes the Amazon Web Service's Software Development Kit (SDK) to communicate with select parts of Seamless' infrastructure, including the Step Functions.

Developer Usage

1. Run npm install
2. Initialize .env with variables matching those found in .env.example. Specify a DATABASE_URL to use during development or deployment.
3. Run npx prisma migrate deploy to setup the schema and perform subsequent schema migrations.
