⚛️ GraphQL API template with advanced filtering & pagination on top of a PostgreSQL database, powered by NestJS & Prisma 搭配了全套增删查改，过滤参数以及带有订阅数据功能的 GraphQL API

🌱 NestJS + GraphQL + Prisma + PostgreSQL Template

Description

GraphQL API template that supports:

1. All CRUD purposes with advanced filtering capabilities across all data types for all columns
2. Disallowing & prohibiting updates on system fields such as createdAt and updatedAt
3. Offset-based Pagination on Payment table
4. Subscription for the latest updated/created Payment

Other features:

• CRON job updating random DB row every 12 hours to keep Supabase free tier DB running (they turn off DBs that aren't active within 7 days)
• Deployed to Render.com @ https://nest-graphql-prisma-g5s7.onrender.com/graphql

Database-related

Hosted DB provider: Supabase

Sadly Heroku will take down all free-tier services from Oct 2022, so I had to find alternative solutions to Heroku Postgres

# Create postgres database in local docker container
1. Download Docker
2. Open it
3. In project root folder run the following command
$ yarn docker:db

# Initialise the database (setting up schema & seeding) - once it has been created in docker
$ yarn db:init

# seeding database
$ npx prisma db seed

nest-graphql-prisma's Issues

[Subscription]: need subscribePayments resolver to have filter type of PaymentFindManyArgs

Problem:
No idea how to implement filter type of PaymentFindManyArgs into subscribePayments resolver

What I've tried:
I know how basic subscription filters work, like this repo and NestJS docs, but they are not flexible enough.
