Deploying Your Next.js App on AWS S3

Using Amazon Web Services (AWS) Simple Storage Service (S3) to host static and server-rendered React apps is a dependable and scalable solution. AWS S3 offers worldwide availability, security features, and low cost, making it a perfect alternative for launching your Next.js application. We will lead you through the process of hosting your Next.js application on AWS S3, assuring a flawless deployment experience, in this step-by-step guide.

Prerequisites:

To successfully follow this guide, you should have the following prerequisites:

• Basic knowledge of Next.js, React.js, and JavaScript
• An active AWS account with appropriate permissions
• A Next.js application ready for deployment
• AWS Command Line Interface (CLI) installed on your local machine

Step 1: Create an S3 Bucket

1. Log in to your AWS Management Console and navigate to the S3 service.
2. Click on "Create Bucket" and provide a unique name for your bucket.
3. Select the AWS region closest to your target audience for optimal performance.
4. Leave the other options as default and click "Create" to create the bucket.

Step 2: Configure the S3 Bucket

1. Once your bucket is created, select it from the S3 dashboard.
2. Go to the "Properties" tab and click on "Static website hosting."
3. Choose the "Use this bucket to host a website" option.
4. Set the "Index document" to the appropriate file path for your Next.js app (e.g., "index.html").
5. Optionally, configure an "Error document" to handle 404 errors.
6. Save the configuration settings.

Step 3: Prepare Your Next.js App for Deployment

1. In your project's root directory, open the terminal.
2. Run the command npm run build or yarn build to build your Next.js app for production.
3. This process generates a ".next" folder containing the optimized static and server-rendered assets.

Step 4: Deploy Your Next.js App to S3

1. Ensure that the AWS CLI is installed on your local machine.
2. Open the terminal and run aws configure to set up your AWS credentials. Follow the prompts and enter your access key, secret key, preferred region, and default output format.
3. Once configured, execute the following command to upload your Next.js app's build folder to the S3 bucket:

aws s3 sync .next/ s3://your-bucket-name

Replace "your-bucket-name" with the actual name of your S3 bucket.
4.Wait for the upload to complete. Your Next.js app's files will now be present in the S3 bucket.

Step 5: Enable Public Access to Your Next.js App

1. Go back to your S3 bucket in the AWS Management Console.
2. Select the "Permissions" tab and click on "Bucket Policy."
3. In the bucket policy editor, paste the following policy, which grants public read access to the bucket contents:

{
  "Version":"2012-10-17",
  "Statement":[{
    "Sid":"PublicReadGetObject",
    "Effect":"Allow",
    "Principal": "*",
    "Action":["s3:GetObject"],
    "Resource":["arn:aws:s3:::your-bucket-name/*"]
  }]
}

Replace "your-bucket-name" with the name of your S3 bucket.
4.Save the policy to enable public access.

Step 6: Configure DNS (Optional)

1. If you have a custom domain, you can configure it to point to your S3 bucket.
2. Go to your domain provider's website and locate the DNS management settings.
3. Create a new CNAME record and assign it a subdomain (e.g., "www" or any other desired subdomain).
4. Set the CNAME target to your S3 bucket's endpoint. To find the endpoint, go to your S3 bucket's properties and copy the "Endpoint" URL.
5. Save the DNS settings and allow some time for the changes to propagate.

Step 7: Test Your Next.js App

1. After the DNS changes have propagated, you can access your Next.js app using either the S3 bucket URL (provided in the bucket properties) or your custom domain (if configured).
2. Open a web browser and enter the URL. You should see your Next.js app up and running, including both the statically generated and server-rendered pages.

Conclusion:

You have successfully deployed your Next.js app on AWS S3 by following this step-by-step guide. AWS S3 is an excellent alternative for hosting your Next.js projects since it provides a dependable and scalable infrastructure for providing static and server-rendered Next.js apps. Remember to create and deploy your Next.js project to the S3 bucket, as well as configure public access and, if desired, DNS for a custom domain. You can take advantage of AWS S3's global availability and solid infrastructure by hosting your Next.js app there, assuring optimal performance for your website users.
