if (req.type === ActivityTypes.Message) {
const context = new TurnContext(adapter, req);
context.sendActivity('Hello, I am your chatbot!');
const restify = require('restify');
const server = restify.createServer();'/api/messages', (req, res) => {
adapter.processActivity(req, res, async (context) => {
// Your bot's logic goes here
server.listen(3978, () => {
console.log(`Bot is listening on http://localhost:3978`);
