GraphQL Server with MongoDB, Node.js and apollo-server

This is a basic implimentation of graphQL backend with mongoDB using Apollo.

To start make an account on mlab if you don't have one. Create new MongoDB Deployment by clicking on Create New button. Once you've created a new deployment, create a new user for the deployment and copy-paste the MongoDB URI and your secret in

config
  --> databaseconfig.js

The URI looks like so :

mongodb://<dbuser>:<dbpassword>@ds119160.mlab.com:19160/<dbname>

Next, install dependencies and run the server -

npm install 
node server.js

Querying in GraphiQL

Once the server has started go to

localhost:3000/graphiql
