📜 NestJs GraphQL Server with MongoDB

NestJS GraphQL Server with MongoDB, a powerful and scalable tech stack that offers a robust foundation for building efficient server-side applications.

NestJS provides a modular and type-safe framework, while GraphQL serves as a powerful query language and runtime, providing a single endpoint to reduce network overhead and enable precise data retrieval.

MongoDB, a flexible NoSQL database, ensures seamless integration and efficient data retrieval.

How to run

Install MongoDB and run it locally. Alternatively, you can pull a docker image for MongoDB and run it.
```
$ docker pull mongo:latest
$ docker run -d -p 27017:27017 --name=mongo-dev mongo:latest
$ docker ps
```

Run the command

$ git clone https://github.com/nc1z/demo-nestjs-graphql-server.git
$ cd demo-nestjs-graphql-server/
$ npm run start:dev

Now you have the endpoint localhost:3000/graphql exposed and ready to be queried!

How to query

Via GraphQL playground

Simply head to localhost:3000/graphql and write your queries in the field. For example:

Hello world

  {
    hello
  }

Create a User

  mutation {
    createUser(input: {name: "Mary Jane", age: 18, email:"mj@gmail.com"}) {
      id
      name
      age
      email
    }
  }

Via Postman

Create a POST request and select the request body as GraphQL

How the project was setup

Setup GraphQL module
Setup GraphQL resolvers
