enablePullRequestPreview

Sets whether pull request previews are enabled for each branch that Amplify Hosting automatically creates for your app. Amplify creates previews by deploying your app to a unique URL whenever a pull request is opened for the branch. Development and QA teams can use this preview to test the pull request before it's merged into a production or integration branch. To provide backend support for your preview, Amplify Hosting automatically provisions a temporary backend environment that it deletes when the pull request is closed. If you want to specify a dedicated backend environment for your previews, use the PullRequestEnvironmentName property. For more information, see Web Previews in the AWS Amplify Hosting User Guide .
