The Sync Function<\/a> is one of the fundamental components of Sync Gateway: its main responsibility is to define which user has access to which documents. In this screencast, you\u2019ll learn how to use the public channel (also known as the ! channel) to synchronize documents to users that haven\u2019t logged into your app yet. This feature is particularly useful when designing the on boarding journey with dynamic data that can be changed on the backend and pulled automatically when the user starts the app for the first time. We\u2019ll consider a note taking application and explore the following:<\/p>\n

    \n
  1. Use the public channel to insert the Getting Started<\/strong> note, you can think of it as the tutorial note when the user starts the app for the first time<\/li>\n
  2. Map the note created by a registered user to a channel that is only accessible by that user<\/li>\n
  3. Enforce write permissions with the requireUser<\/strong> method<\/li>\n
  4. Test the Sync Function with curl commands<\/li>\n<\/ol>\n
