Send a GraphQL query to your API and get exactly what you need, nothing more and nothing less. GraphQL queries always return predictable results. Apps using GraphQL are fast and stable because they control the data they get, not the server.

Open a terminal window and clone the project cd into the project server directory and install dependent packages by running `npm install` and finally run the command `node server.js`. The…
