Activity: Typing

Typing activities represent ongoing input from a user or a bot. This activity is often sent when keystrokes are being entered by a user, although it's also used by bots to indicate they're "thinking," and could also be used to indicate processing, e.g. collecting audio from users.

Typing activities are intended to persist within UIs for three seconds.

// Send a typing indicator to the user upon receiving a message
app.on('message', async ({ send }) => {
    await send({ type: 'typing' });
});

Schema

Typing activities are identified by a type value of typing.

A6000: If able, clients SHOULD display typing indicators for three seconds upon receiving a typing activity.

A6001: Unless otherwise known for the channel, senders SHOULD NOT send typing activities more frequently than one every three seconds. (Senders MAY send typing activities every two seconds to prevent gaps from appearing.)

A6002: If a channel assigns an id to a typing activity, it MAY allow bots and clients to delete the typing activity before its expiration.

A6003: If able, channels SHOULD send typing activities to bots.

Typing indicator UI in Teams

The typing indicator is a small animation that appears in the bottom left corner of the chat window above the message input field when a user or bot is typing.
