⚡ Getting Started

Try the AI Agent Sample app to explore the AI-enabled features and existing Assistant helper:

# Create a new AI Agent app
$ slack create slack-ai-agent-app --template slack-samples/bolt-js-assistant-template
$ cd slack-ai-agent-app/
Add your OPENAI_API_KEY
$ export OPENAI_API_KEY=sk-proj-ahM...
Run the local dev server
$ slack run

After the app starts, send a message to the "slack-ai-agent-app" bot for a unique response.

⌛ Loading States

Loading states allows you to not only set the status (e.g. "My app is typing...") but also sprinkle some personality by cycling through a collection of loading messages:

Web Client SDK:

app.event('message', async ({ client, context, event, logger }) => {
    // ...
    await client.assistant.threads.setStatus({
        channel_id: channelId,
        thread_ts: threadTs,
        status: 'thinking...',
        loading_messages: [
            'Teaching the hamsters to type faster…',
            'Untangling the internet cables…',
            'Consulting the office goldfish…',
            'Polishing up the response just for you…',
            'Convincing the AI to stop overthinking…',
        ],
    });
