How To Deploy A Next.js App On AWS With CDK | Amazon Web Services

Next.js is a popular framework for building server-rendered React applications. It provides a great developer experience with features like automatic code splitting, hot module replacement, and server-side rendering.

AWS CDK (Cloud Development Kit) is a software development framework for defining cloud infrastructure using familiar programming languages. It allows you to define your infrastructure as code using TypeScript, Python, Java, or any other supported language, and automatically provisions the necessary resources on AWS.

Prerequisites

• Node.js installed on your machine
• AWS account with necessary permissions to create resources using CDK
• A Next.js application that you want to deploy

Deploying a Next.js App on AWS with CDK

1. Install the AWS CDK using the following command:

   npm install -g aws-cdk

2. Create a new CDK project using the following command:

   cdk init app --language typescript

3. Install the necessary CDK dependencies for deploying a Next.js app:

   npm install @aws-cdk/aws-s3 @aws-cdk/aws-cloudfront @aws-cdk/aws-route53 @aws-cdk/aws-route53-targets @aws-cdk/aws-certificatemanager @aws-cdk/aws-lambda @aws-cdk/aws-apigatewayv2 @aws-cdk/aws-apigatewayv2-integrations

4. Create a new CDK stack to define the infrastructure for your Next.js app. This stack should define an S3 bucket for hosting your app, a CloudFront distribution for content delivery, and any necessary Route53 settings for custom domain mapping:

   // Example CDK stack for deploying a Next.js app
   import * as cdk from '@aws-cdk/core';
   import * as s3 from '@aws-cdk/aws-s3';
   import * as cloudfront from '@aws-cdk/aws-cloudfront';
   import * as route53 from '@aws-cdk/aws-route53';
   import * as targets from '@aws-cdk/aws-route53-targets';
   import * as acm from '@aws-cdk/aws-certificatemanager';
   
   export class NextjsAppStack extends cdk.Stack {
     constructor(scope: cdk.App, id: string, props?: cdk.StackProps) {
       super(scope, id, props);
   
       // Create S3 bucket for hosting app
       const bucket = new s3.Bucket(this, 'NextjsAppBucket', {
         websiteIndexDocument: 'index.html',
         publicReadAccess: true
       });
   
       // Create CloudFront distribution for content delivery
       const distribution = new cloudfront.CloudFrontWebDistribution(this, 'NextjsAppDistribution', {
         originConfigs: [
           {
             s3OriginSource: {
               s3BucketSource: bucket
             },
             behaviors: [ { isDefaultBehavior: true } ]
           }
         ]
       });
   
       // Create Route53 settings for custom domain mapping
       const zone = route53.HostedZone.fromHostedZoneAttributes(this, 'NextjsAppZone', {
         zoneName: 'example.com',
         hostedZoneId: 'HOSTED_ZONE_ID' // Replace with actual hosted zone ID
       });
       
       const certificate = new acm.Certificate(this, 'NextjsAppCertificate', {
         domainName: 'example.com', // Replace with actual domain
       });
   
       new route53.ARecord(this, 'NextjsAppAlias', {
         zone: zone,
         target: route53.RecordTarget.fromAlias(new targets.CloudFrontTarget(distribution)),
         recordName: 'example.com' // Replace with actual domain
       });
   
       new route53.CfnRecordSet(this, 'NextjsAppRecordSet', {
         name: 'example.com', // Replace with actual domain
         type: 'A',
         aliasTarget: {
           dnsName: distribution.distributionDomainName,
           hostedZoneId: distribution.distributionHostedZoneId
         },
         hostedZoneId: 'HOSTED_ZONE_ID' // Replace with actual hosted zone ID
       });
     }
   }
   
   const app = new cdk.App();
   new NextjsAppStack(app, 'NextjsAppStack');
   

5. Deploy the CDK stack to create the necessary resources on AWS using the following command:

   cdk deploy

Conclusion

Deploying a Next.js app on AWS using CDK allows you to define your infrastructure as code and easily provision the necessary resources for hosting your application. By following the steps outlined in this article, you can quickly deploy your Next.js app on AWS and take advantage of the scalability and reliability of the AWS cloud platform.
