How to configure Route 53 for Nuxt.js on AWS?

To configure Route 53 for Nuxt.js on AWS, follow these steps:

1. Create or sign in to your AWS account.
2. Open the Amazon Route 53 console.
3. Click on "Hosted Zones" in the left sidebar, then click on "Create Hosted Zone" to create a new hosted zone.
4. Enter a domain name that you own in the "Domain Name" field (e.g., "example.com").
5. Click on "Create" to create the hosted zone.
6. Once the hosted zone is created, you will see the NS (name server) records for the hosted zone. Take note of these NS records as you will need to update your domain registrar's DNS settings with these NS records.
7. Sign in to your domain registrar's account and go to the DNS settings for your domain.
8. Update the NS records for your domain with the NS records provided by Route 53 in the previous step.
9. Go back to the Route 53 console and click on "Create Record Set" to create a new record set.
10. In the "Name" field, enter the subdomain or domain you want to use for your Nuxt.js app (e.g., "www").
11. Select the record type based on your requirements (e.g., "A" for an IPv4 address).
12. In the "Value" field, enter the IP address of your Nuxt.js server or load balancer.
13. (Optional) Set a TTL (Time to Live) value for the record.
14. Click on "Create" to create the record set.
15. Repeat steps 9-14 to create additional record sets for other subdomains or domains, if needed.

Once the DNS propagation is complete (this may take some time), your Nuxt.js app should be accessible using the configured domain or subdomain.

How to backup and restore Nuxt.js app hosted on AWS?

To backup and restore a Nuxt.js app hosted on AWS, you can follow these steps:

Backup:

1. Set up automated backups: Use AWS services like Amazon RDS or Amazon EBS to automatically create backups of your Nuxt.js app's database or storage.
2. Create an AMI: Create an Amazon Machine Image (AMI) of the instance where your Nuxt.js app is hosted. This will capture the entire state of the instance, including the app, dependencies, and configurations.
3. Store application code: Ensure that the source code of your Nuxt.js app is stored in a version control system like Git. Regularly push updates and changes to the repository to keep it up to date.

Restore:

1. Launch a new EC2 instance: To restore your Nuxt.js app, launch a new EC2 instance with the desired configuration and size.
2. Deploy the app code: Clone or pull the source code from the version control system onto the new instance. Install the necessary dependencies by running "npm install" or "yarn install" in the app's directory.
3. Configure environment variables: If your app uses environment variables, ensure they are correctly set on the new instance.
4. Restore database or storage: If you have backed up your database or storage, restore it using the backup procedure provided by AWS services like Amazon RDS or Amazon EBS.
5. Start the app: Start the Nuxt.js app by running the appropriate command, such as "npm run start" or "yarn run start" in the app's directory. Verify that the app is working correctly.
