Creates a preview of your project that you can test before you release it.
The command uploads your build output to Wix's servers as a preview and displays links to that preview. You can share the links with team members so they can test your project too. Each preview stays as it was when you created it, so later changes to your project don't affect it. A preview doesn't create an app version or publish a headless project's site.
Note: This command uploads your project's build output, so you must run the build command after every change you want to preview. In a project created with create init, the CLI has no build command, and this command uploads your build output from the directory set in site.outputDirectory.
