How to Setup GraphQL with Node.js on Debian based distro

To gather information from the REST API designed app you need to send requests to multiple REST endpoints. So this kind of approach is scattered across multiple endpoints. GraphQL solves these obvious flaws and instead of sending requests through multiple endpoints, it has only one endpoint where you can gather data from multiple collections. In this tutorial, I will explain how to setup GraphQL with Node.js on Debian based distro.


Setup GraphQL environment

Step 1. Navigate the project directory path and run:

npm init

Step 2. Install GraphQL:

npm install graphql --save

Create basic GraphQL API to handle queries

Put the follwing code into the server.js file:

var { graphql, buildSchema } = require('graphql');

var schema = buildSchema(`
  type Query {
    hellographql: String

var root = {
  hellographql: () => {
    return 'Hello GraphQL!!!';

graphql(schema, '{ hellographql }', root).then((response) => {

Once you are done, run the API with:

node server.js

The output should be:

{ data: { hello: 'Hello GraphQL!!!' } }


If you work on more complex GraphQL scenarios you will have to run GraphQL queries from an API server instead of using cli. Feel free to leave a comment below and if you find this tutorial useful, follow our official channel on telegram.
