Getting started

Installation

Clone the repository

git clone https://github.com/lujakob/nestjs-realworld-example-app.git

Switch to the repo folder

cd nestjs-realworld-example-app

Install dependencies

npm install

Copy config file and set JsonWebToken secret key

cp src/config.ts.example src/config.ts

---

Database

The codebase contains examples of two different database abstractions, namely TypeORM and Prisma.

The branch master implements TypeORM with a mySQL database.

The branch prisma implements Prisma with a mySQL database.

---

TypeORM

---

Create a new mysql database with the name nestjsrealworld
(or the name you specified in the ormconfig.json)

Copy TypeORM config example file for database settings

cp ormconfig.json.example

Set mysql database settings in ormconfig.json

{
  "type": "mysql",
  "host": "localhost",
  "port": 3306,
  "username": "your-mysql-username",
  "password": "your-mysql-password",
  "database": "nestjsrealworld",
  "entities": ["src/**/**.entity{.ts,.js}"],
  "synchronize": true
}

Start local mysql server and create new database 'nestjsrealworld'

On application start, tables for all entities will be created.

---

Prisma

---

To run the example with Prisma checkout branch prisma, remove the node_modules and run npm install

Create a new mysql database with the name nestjsrealworld-prisma (or the name you specified in prisma/.env)

Copy prisma config example file for database settings

cp prisma/.env.example prisma/.env

Set mysql database settings in prisma/.env

DATABASE_URL="mysql://USER:PASSWORD@HOST:PORT/DATABASE"

To create all tables in the new database make the database migration from the prisma schema defined in prisma/schema.prisma

npx prisma migrate save --experimental
npx prisma migrate up --experimental

Now generate the prisma client from the migrated database with the following command

npx prisma generate

The database tables are now set up and the prisma client is generated. For more information see the docs:
