What's Changed (beta)

This beta release contains feature enhancements to Bolt JS for developers participating in the Slack Platform Beta 🚀

Compatible with the Slack CLI tool

Create a new app from a Github sample template

$ slack create my-app -t slack-samples/bolt-js-starter-template -b future

Run your app for local development from the CLI. We take care of installation, tokens and starting the app in development mode.

$ slack run 

Configure your app in code

Declare a manifest.js or manifest.ts file import handly utility functions and define any recomposable units contained such as Functions, Workflows and Triggers.

# my-app/manifest.js

const { Manifest } = require('@slack/bolt');
module.exports = Manifest({
  runOnSlack: false,
  name: '',
  displayName: '',
  description: '',
  botScopes: ['chat:write'],
  socketModeEnabled: true,
  workflows: [TimeOffWorkflow],
  features: {
    appHome: {
      messagesTabEnabled: true,
      messagesTabReadOnlyEnabled: true,
    },
  },
  settings: {
    interactivity: {
      is_enabled: true,
    },
    org_deploy_enabled: false,
  },
});

Compose Custom Function handling logic via a SlackFunction.

Write a recomposable unit of logic:

Example:

    const myFunc = new SlackFunction('fn_callback_id', () => {});

Attach optional handlers for block_action and view events related to your function.

Example:

   myFunc.action('action_id', () => {})
         .view('view_callback_id', () => {});
