Socket Mode

Slack Socket Mode

For baseline package documentation, please see the project’s README or the documentation on npm.

The following contain additional examples that may be useful for consumers.

Listen for Interactivity Events

To receive interactivity events such as shorcut invocations, button clicks, and modal data submission, your listener can subscribe to “interactive” events.

const { WebClient } = require('@slack/web-api');
const webClient = new WebClient(process.env.SLACK_BOT_TOKEN);

socketModeClient.on('interactive', async ({ body, ack }) => {
  await ack();
  if (body.callback_id === "the-shortcut") {
    // handle the shortcut here
    await webClient.views.open({
      trigger_id: body.trigger_id,
      view: {
        type: "modal",
        title: {
          type: "plain_text",
          text: "My App"
        },
        close: {
          type: "plain_text",
          text: "Close"
        },
        blocks: [
          {
            type: "section",
            text: {
              type: "mrkdwn",
              text: "Hi there!"
            }
          }
        ]
      }
    });
  }
});

For slash commands, you can subscribe to “slash_commands” events and dispatch requests inside the listener.

socketModeClient.on('slash_commands', async ({ body, ack }) => {
  if (body.command === "/the-command") {
    await ack({"text": "I got it!"});
  }
});

When your app has multiple interactive events or slash commands, you will need to include your own routing logic. This is a good time to consider using Slack’s Bolt framework, which provides an easier way to register listeners for events and user actions. You can learn more in Bolt’s Socket Mode documentation.
