    Bot Builder for Node.js

    Bot Builder for Node.js is a powerful framework for constructing bots that can handle both freeform interactions and more guided ones where the possibilities are explicitly shown to the user. It is easy to use and models frameworks like Express & Restify to provide developers with a familiar way to write Bots.

    Build a bot

    Read the quickstart guide that will walk you through setting up your Bot Builder app so that you've got a well structured project and all of the tools necessary to develop and extend your bot.

    Start from scratch

    Create a folder for your bot, cd into it, and run npm init.

    npm init

    Get the BotBuilder and Restify modules using npm.

    npm install --save botbuilder
    npm install --save restify

    Create a file named bot.js and get your bot online with a few lines of code.

    const restify = require('restify');
    const botbuilder = require('botbuilder');
    // Create bot adapter, which defines how the bot sends and receives messages.
    var adapter = new botbuilder.BotFrameworkAdapter({
        appId: process.env.MicrosoftAppId,
        appPassword: process.env.MicrosoftAppPassword
    // Create HTTP server.
    let server = restify.createServer();
    server.listen(process.env.port || process.env.PORT || 3978, function () {
        console.log(`\n${} listening to ${server.url}`);
        console.log(`\nGet Bot Framework Emulator:`);
    // Listen for incoming requests at /api/messages.'/api/messages', (req, res) => {
        // Use the adapter to process the incoming web request into a TurnContext object.
        adapter.processActivity(req, res, async (turnContext) => {
            // Do something with this incoming activity!
            if (turnContext.activity.type === 'message') {            
                // Get the user's text
                const utterance = turnContext.activity.text;
                // send a reply
                await turnContext.sendActivity(`I heard you say ${ utterance }`);

    Test your bot

    Use the Bot Framework Emulator to test your bot on localhost.

    Install the emulator from here and then start your bot in a console window.

    Start the emulator and say "hello" to your bot.

    Publish your bot

    Deploy your bot to the cloud and then register it with the Azure Bot Service.
