poc-typescript-nestjs-graphql

Requirements

• NodeJS
• MongoDB database

Getting started

Installing dependencies

First, you need to install all the needed dependencies.

$ yarn

Configuring the database

Before starting the application, you will need to create a MongoDB database and edit the connection string in the app.modules.ts file to match your database configuration. The repository includes a Docker-Compose file that helps you start MongoDB.

docker-compose up -d mongodb

The default database configuration in the app.module.ts file looks like this:

@Module({
  imports: [MongooseModule.forRoot('mongodb://localhost/nest')],
})

If you are not running the database on your local machine, replace localhost with the correct IP-Address.

Starting the application

After installing the dependencies, you can run the application using one of the following commands.

# development
$ yarn start

# watch mode
$ yarn start:dev

# production mode
$ yarn start:prod

Testing the application

After starting the application you can start using it by either opening the GraphQL playground on http://localhost:3000/graphql or sending a request through an HTTP client like Postman or Insomnia.
