A progressive Node.js framework for building efficient and scalable server-side applications.

Simple Blog API ( CRUD users, users CRUD posts, users upload files )

Prisma GraphQL schema-first Hybrid application

This hybrid project uses GraphQL API query language for clean responses, TCP transport layer for microservice, @nestjs/testing which uses jest for unit testing and MySQL as the relational database and MongoDB as no-sql database for constantly changing or growing data such as posts.

To connect other microservices uncomment examples in main.ts, replace jest with vitest and to use a different database, check the Prisma docs e.g.

to use CockroachDB

// schema.prisma
datasource db {
  provider = "cockroachdb"
  url      = env("DATABASE_URL")
}

// docker-compose.yml
  cockroachdb:
    image: cockroachdb/cockroach
    restart: always
    ports:
      - "26257:26257"
      - "8080:8080"
    command: start-single-node --cluster-name=node1 --logtostderr=WARNING --log-file-verbosity=WARNING --insecure
    environment:
      - COCKROACH_USER=${DATABASE_USER}
      - COCKROACH_PASSWORD=${DATABASE_PASSWORD}

Installation

1. Run multi-container Docker applications

# run mongodb, mongo express container
$ docker-compose -f docker-compose-mongo.yml up -d
# run mysql, phpmyadmincontainer
$ docker-compose up -d

2. Install dependencies: npm install
3. Generate TypeScript type definitions for the GraphQL schema: npm run generate:typings
4. Generate a type-safe client to interact with your database: npm run prisma:gen
5. Create mariadb/mysql database and create tables: npm run prisma:push
6. Start server: npm run start:dev

Test

# unit tests
$ npm run test

# e2e tests
$ npm run test:e2e

# test coverage
$ npm run test:cov
