Simple MongoDB CRUD example demonstrating the Nestjs application structure as well as how you can work with databases. For an in-depth explanation of the application and the basic Nestjs concepts, you can follow this article.

Requirements

• NodeJS
• MongoDB database

Getting started

Installing dependencies

First, you need to install all the needed dependencies.

$ npm install

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

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
$ npm run start

# watch mode
$ npm run start:dev

# production mode
$ npm run start:prod
