Publishing & Domains
Publishing your app
Taking a project from preview to a live, public URL.
One-click publish
When you are ready, publishing takes a snapshot of your current app and puts it on its own always-on URL, separate from your in-progress preview.
Redeploying
Publishing again after further changes updates the live version. Your published app keeps running on the previous version until the new one is ready, so visitors never see a broken state mid-deploy.
