How to use [sockets.user.add-to-group]

The reference page of sockets.user.add-to-group has its arguments, constraints and declaration.

You can associate a user with one or more groups. This is done with the following slots.

• [sockets.user.add-to-group] - Adds the specified user to the specified group
• [sockets.user.remove-from-group] - Removes the specified user from the specified group

Below you can find an example of how to add a user to a group, for then to later de-associate the user with the group.

// Associating a user with a group.
sockets.user.add-to-group:some-username-here
   group:some-group-name-here

// Publishing message, now to group, such that 'some-username-here' gets it
sockets.signal:foo.bar
   group:some-group-name-here
   args
      howdy:world

// De-associating the user with the group again.
sockets.user.remove-from-group:some-username-here
   group:some-group-name-here

Notice - SignalR users might have multiple connections. This implies that once you add a user to a group, all connections are associated with that group. The message will only be published to connections explicitly having registered an interest in the foo.bar message for our above example, irrelevant of whether the user belongs to the group or not.
