In today’s tech-driven world, deploying applications to the cloud has become the norm. The versatility and scalability provided by cloud platforms make them an ideal choice for hosting a JavaScript GraphQL server. In this article, we will explore the steps involved in deploying a JavaScript GraphQL server to the cloud.

Choosing a Cloud Platform

Before deploying our GraphQL server, we need to select a suitable cloud platform. There are numerous options available, such as AWS, Google Cloud, and Azure. Let’s choose AWS for this example.

Setting up an AWS Account

To get started, we need to create an AWS account. Head over to the AWS website and follow the registration process. Once your account is ready, we can proceed to set up our GraphQL server.

Building the GraphQL Server

For our GraphQL server, we will be using Node.js and the popular apollo-server-express package.

const express = require("express");
const { ApolloServer, gql } = require("apollo-server-express");

const typeDefs = gql`
  type Query {
    hello: String
  }
`;

const resolvers = {
  Query: {
    hello: () => "Hello, GraphQL!"
  }
};

const server = new ApolloServer({ typeDefs, resolvers });

const app = express();
server.applyMiddleware({ app });

const PORT = process.env.PORT || 4000;
app.listen(PORT, () => {
  console.log(`GraphQL server running on port ${PORT}`);
});

The above code sets up a simple GraphQL server with a single “hello” query. Feel free to add your own schema and resolvers to customize it further.

Deploying to AWS

1. Install the AWS CLI tools on your machine if you haven’t already.

2. Open a terminal and run the following command to configure your AWS credentials:

   aws configure
   

3. Enter your AWS Access Key ID, Secret Access Key, default region, and output format as prompted.

4. Once your AWS credentials are set up, run the following command to deploy your GraphQL server to an AWS Elastic Beanstalk environment:

   eb init
   

   Follow the prompts to select a region, application name, and environment name.

5. After initialization, run the following command to deploy your application:

   eb create
   

   This will create the necessary AWS resources and deploy your application.

6. Once the deployment is complete, you will receive a URL where your GraphQL server is accessible.

Conclusion

Deploying a JavaScript GraphQL server to the cloud is a straightforward process. By choosing a cloud platform like AWS and following the steps outlined in this article, you can quickly make your GraphQL server accessible to the world. The cloud provides the flexibility and scalability needed to handle growing user demands effectively.
