Typing Indicators

LAST EDIT Jul 21 2021

All official SDKs support typing events out of the box and are handled on all channels with the typing_events featured enabled. Typing indicators allow you to show to users who is currently typing in the channel. This feature can be switched on/off on a channel-type basis using the CLI or directly from the Dashboard. If you are using one of the official SDK libraries, you will only need to ensure that typing indicators are enabled to get this working.

If you are building your UI on top of one of our Chat Clients instead, you will need to take care of four things:

  1. Send an event typing.start when the user starts typing

  2. Send an event typing.stop after the user stopped typing

  3. Handle the two events and use them to toggle the typing indicator UI

  4. Use parent_id field of the event to indicate that typing is happening in a thread

When sending events on user input, you should make sure to follow some best-practices to avoid bugs.

  1. Only send typing.start when the user starts typing

  2. Send typing.stop after a few seconds since the last keystroke

Because clients might fail at sending typing.stop event all Chat clients periodically prune the list of typing users.
