Building a GraphQL API with Node.js and MongoDB

Introduction

Hey there! Imagine you’re building a real-world API that not only fetches user data but also stores and retrieves it from a database. That’s where MongoDB comes into play! In this guide, we’ll integrate MongoDB with our GraphQL API to store and manage user data effectively.

You should have some familiarity with Node.js, GraphQL, and MongoDB. If you don’t have MongoDB installed, consider using MongoDB Atlas (a cloud-hosted MongoDB solution).

Let’s dive in!

1. Setting Up Your Project

Step 1: Create a New Project Directory

mkdir graphql-mongo-api && cd graphql-mongo-api

Step 2: Initialize Your Project

npm init -y

Step 3: Install Dependencies

Install the necessary packages:

npm install express graphql express-graphql mongoose dotenv

2. Project Structure

Here’s the project structure for our MongoDB-powered GraphQL API:

graphql-mongo-api/
├── index.js
├── schema/
│   ├── schema.js
│   └── resolvers.js
├── models/
│   └──…
