Exa Bot Builder

This is a port of Claudia Bot Builder that allows to use Express.

npm npm npm

Exa Bot Builder helps developers create and deploy chat-bots for various platforms in minutes to AWS Lambda or using Express. It simplifies the messaging workflows, automatically sets up the correct web hooks, and guides you through configuration steps, so that you can focus on important business problems and not have to worry about infrastructure code.

Here's a simple example:

AWS Lambda

const botBuilder = require('exa-bot-builder');
const excuse = require('huh');
module.exports = botBuilder(function (message) {
  return 'Thanks for sending ' + message.text +
    'Your message is very important to us, but ' +


const botBuilder = require('exa-bot-builder');
const excuse = require('huh');
module.exports = botBuilder(function (message) {
  return 'Thanks for sending ' + message.text +
    'Your message is very important to us, but ' +
}, { "aws": false, "express": true });

This code is enough to operate bots for all supported platforms. Exa Bot Builder automatically parses the incoming messages into a common format, so you can handle it easily. It also automatically packages the response into the correct message template for the requesting bot, so you do not have to worry about individual bot protocols.

Frequently asked questions

  1. How to run it locally?

You can start it passing configuration options as defined on the following example:

  const botBuilder = require('exa-bot-builder');
  const excuse = require('huh');
  module.exports = botBuilder(function (message) {
    return 'Thanks for sending ' + message.text +
      'Your message is very important to us, but ' +
  }, { "aws": false, "express": true });

The above will start a new express on port 3000.

  1. How to test your bot?

    Your chat bot is just a Lambda function or web API, which means it is just a simple JavaScript function and you should be able to, at least in theory, run everything locally as simple automated tests.

    The most important thing is to design testable Lambda functions, this guide will help you to do that.

    Integration tests can be a bit more complex if you have some integrations with external or AWS services. Check this guide to see how to write integration tests and run automated tests locally.

  2. My Facebook messenger bot responds to my messages only. Why it's not responding to everyone?

    Facebook has a review process for chat bots. Make sure your bot is approved.

  3. Can I send Slack slash command delayed responses?

    Yes, here's the tutorial for that.

  4. What's new in v2?

    It's a new major version because of the dependencies - there are big improvements in the Claudia API Builder and Claudia, so Claudia Bot Builder v1.x is not compatible with them.
    V2.x also brings support for many new platforms.

  5. How to speed up the deployment

    You can use claudia update with --cache-api-config flag to cache the API Gateway config, for more info visit docs page for claudia update.

    Also, from version 2.7.0, you can disable platforms that you are not using, check the full explanation in the API docs.
