Slack DevKit

Slack DevKit is a light-weight developer kit to build Slack Apps in node.js super fast. No previous knowledge about building Slack Apps or Bots needed! Plus, automatic support for verifying requests from Slack and responding to validations.

This was made to build Slack Apps on Glitch even faster, but it works everywhere!

const Slack = require('slack-devkit');

// Configure express with the Slack App settings
const { server } = new Slack({

// All GET routes redirect to the “Add to Slack” OAuth flow
server.get('/', (req, res) => {
  req.slack.data; // the authenticated workspace info
  res.send();
});

// All POST routes expect Slack callback events
// and verify against the verification token
server.post('/', (req, res) => {
  const user = req.slack.user_id;
  req.slack.api('users.info', { user }).then(r => {
    r.data; // the results of 'users.info' API request
  });
