Express.js GraphQL Demo with Apollo Server

This is a small project that demonstrates how to use GraphQL with Express.js and Apollo Server. It provides a basic setup to create a GraphQL API server using Express.js and Apollo Server.

Prerequisites

Before running this project, ensure that you have the following dependencies installed on your system:

  • Node.js (version 12 or later)
  • npm (Node Package Manager)

Installation

Follow the steps below to set up and run the project:

  1. Clone the repository or download the source code:

    git clone https://github.com/niushay/express-graphql.git

  2. Navigate to the project directory:

    cd express-graphql

  3. Install the required dependencies:

    npm install

Usage

To start the server and run the project, execute the following command:

npm start

Once the server is running, you can access the GraphQL playground at http://localhost:4000/graphql. The playground provides an interactive interface to test and explore the GraphQL API.

Project Structure

The project structure is organized as follows:

express-graphql/
  ├── orders/
  │   ├── resolvers.js
  │   └── graphql
  │   └── model.js
  ├── products/
  │   ├── resolvers.js
  │   └── graphql
  │   └── model.js
  ├── server.js
  └── package.json
  • /resolvers.js: This file contains the resolver functions that define how the GraphQL server handles different queries and mutations.
  • /graphql.js: Here, you define the GraphQL schema. It includes the types, queries, and mutations supported by your API.
  • server.js: This is the main entry point of the application. It sets up the Express.js server and integrates Apollo Server with the defined schema and resolvers.
  • package.json: The package configuration file containing project metadata and dependencies.
