How can I configure HTTPS for my Elastic Beanstalk environment?


I have a backend built with Express and Node.js using TypeScript. I'm using the cors package to enable cross-origin resource sharing. The backend is deployed on Elastic Beanstalk and works correctly when I test it using Postman.

I also have a frontend built with Next.js and TypeScript. When I run the frontend locally, the API requests to the backend run correctly. However, when I deploy the frontend to an S3 bucket or Amplify, the API requests do not work.

  • can you share more details on issue you are facing? Any error message when you try to access the app after deploying it to S3/ amplify?

To configure HTTPS for your Elastic Beanstalk environment, you can follow these steps:

Step 1: Obtain an SSL/TLS Certificate You need an SSL/TLS certificate to enable HTTPS for your Elastic Beanstalk environment. You can obtain a certificate from a trusted certificate authority (CA) or use AWS Certificate Manager (ACM) to request a free certificate.

Here's how to request a certificate using ACM:

Open the ACM console ( Click on "Request a certificate" and enter your domain name. Choose a validation method (DNS validation is recommended). Follow the prompts to complete the certificate request process and wait for it to be issued. Step 2: Configure Security Group To allow HTTPS traffic to your Elastic Beanstalk environment, you need to configure the security group associated with your environment to allow incoming traffic on port 443 (HTTPS).

Here's how to configure the security group:

Open the EC2 console ( Go to "Security Groups" and find the security group associated with your Elastic Beanstalk environment. Edit the inbound rules of the security group to allow incoming traffic on port 443 (HTTPS). Step 3: Update Elastic Beanstalk Configuration To enable HTTPS for your Elastic Beanstalk environment, you need to update the environment configuration to use the SSL certificate and forward HTTPS traffic to your backend.

Here's how to update the configuration:

Open the Elastic Beanstalk console ( Go to your environment and click on "Configuration" in the sidebar. In the "Load Balancer" section, click on "Edit". Select the SSL certificate you obtained in Step 1. Enable the "Secure listener" option and choose the port (typically 443). Save the configuration changes. Step 4: Update CORS Configuration If your frontend is deployed to a different domain or subdomain than your backend, you may need to update the CORS configuration on your backend to allow requests from the frontend domain.

In your Express/Node.js backend, you can use the cors package to configure CORS. You'll need to set the Access-Control-Allow-Origin header to the domain of your frontend.

Example code for enabling CORS in your backend:

javascript Copy code const express = require('express'); const cors = require('cors');

const app = express();

// Enable CORS app.use(cors({ origin: '' // Replace with your frontend domain }));

// of your backend code

app.listen(3000, () => { console.log('Server is running on port 3000'); }); Make sure to replace '' with the actual domain or subdomain of your frontend.

After completing these steps, your Elastic Beanstalk environment should be configured to use HTTPS. Make sure to redeploy your backend to ensure the changes take effect.
