Preview deployment action

Warning

The action is in testing and it's not recommended to use in production environments.

The work you can find here is inspired by Vercel Preview deployments and this is an attempt to create great Pull requests review experience if you are already deploying your website to AWS S3.

Github Action to deploy your static website on AWS S3. The action is only availabke to use as part of your Pull request workflow and does the following:

• Create AWS Cloudfront (one for all preview deployments)
• Create AWS S3 Bucket (one for all preview deployments)
• Create Route53 and Cloudfront links based on Pull request name
• Sync build folder and S3 content
• Integrate with GitHub deployments for better developer experience

Usage

To quickly start with action:

• Copy the file provided below to .github/workflows/preview.yml
• Replace parameters with your own ones
• If you need to build static files, just add steps before calling preview-deployment-action
• Add AWS access keys as Github Secrets. They are needed to create Route53, Cloudfront, S3 resources.
