Chat admin privileges

This is an easy way to give your app users different roles and capabilities. This can be a useful functionality when you’re managing live experiences with multiple participants. For example, in a chat room where one user needs admin or moderator privileges to delete spam or inappropriate content.

Switch between roles

You have the ability to give users different roles in different parts of your application, and you can switch those roles at any time. In the chat example, you would give one user admin role in a specific chat room, while they stay a simple participant in all other chat rooms. The user can only delete other user’s comments in the room where he has admin privileges.

Other Possible Features?

Ably gives you the flexibility to create a wide range of app features using the same basic building blocks. For example, beyond  the message deletion use case we showed above, you could use the same logic for:

  • Customizing which users have access to different message interaction types, such as who can reply to a post

  • Including trusted information about the identity of a user in messages they send

Ably Channels

Channel is the unit of distribution of messages. Messages can be anything and a channel can represent a chat room, direct messaging, a virtual event etc. Users or their devices can connect to a specific channel. The Avatar Stack is not related to messages in a channel, but the digital place where an Avatar Stack can be used is the channel itself.

Ably JWT user claims

Ably’s support for JWTs allows a token-based authentication scheme that defines channel capabilities, as well as ‘admin privileges’ — or any other trusted information about a client that can be used to describe a user’s roles. Clients receive information about other clients on each message.
