Bot Framework V4 UniversalBot nodejs

Question

What's the alternative of UniversalBot(v3) in v4. Can anybody give me a straight answer?. I've read the documentation but i can't figure it out.

Answer 1

There are comprehensive v3 to v4 migration docs in the official documentation. You don't mention any sort of context for what you're doing, so I'm going to go with a general answer:

To create a bot instance:

v3

var bot = new builder.UniversalBot(connector, [ ...DIALOG_STEPS ]);

v4

// Define the bot class as extending ActivityHandler.
const { ActivityHandler } = require('botbuilder');

class MyBot extends ActivityHandler {
    // ...
}

// Instantiate a new bot instance.
const bot = new MyBot(conversationState, dialog);

That's off the official migration doc found here
