💬 Sending Activities

To send an activity you can either use the send or reply methods. You can also stream chunks of an activity.

Send

Example: a bot that listens for when a member is added to the conversation and sends a greeting.

app.on('conversationUpdate', async ({ activity, send }) => {
    for (const account of activity.membersAdded || []) {
        await send(`👋 welcome ${account.name}!`);
    }
});

Reply

Example: an echo bot that listens for messages sent to it and responds.

app.on('message', async ({ activity, reply, send }) => {
    await send({ type: 'typing' }); // send typing indicator...
    await reply(`you said: "${activity.text}"`);
});

Streaming

app.on('message', async ({ activity, stream }) => {
    stream.emit('hello');
    stream.emit(', ');
    stream.emit('world!');

    // result message: "hello, world!"
});
