A typescript-based backend featuring :

• NestJS framework to handle architecture, with Fastify
• TypeORM to handle Database requests
• GraphQL to handle centralized and typed requests from frontend
• Unit tests with Jest
• ParcelJS to handle bundling and HMR, alongwith typescript auto-type-checking

1. Manually create a database (without any table)
2. Add your database credentials in settings.ts
3. For each table, prepare its corresponding XXXX.entity.ts schema, where XXXX is the table name.

yarn

I strongly suggest using 4 terminals

yarn start // will start hot-reloading Parcel bundler

yarn type-check // will start Typescript watcher

yarn test // will start unit tests watcher

... and the last one in your IDE for usual commands, etc...
