BotStackjs

Why?

We believe the beginning of a successful bot has little to do with engineering and everything to do with the skill of the product owner in acquiring users and keeping them faster than their competition.

That's why we've open sourced our Facebook Messenger node.js code base so you can get all the latest features from API.AI, Facebook Messenger and Analytics like Dashbot and BotMetrics. While setting yourself up for success with a robust and extensible code base when you've tested your assumptions and are ready for an engineer to build domain specific features.

Installation

• npm install botstack
• set API keys in env_tmpl

Example

Create index.js file with this content:

const BotStack = require('botstack');

class ExampleBot extends BotStack {};

const bot = new ExampleBot('example-bot');
bot.startServer();

Before the start of the bot, we need to set a few environment variables:

FB_PAGE_ACCESS_TOKEN, FB_VERIFY_TOKEN, APIAI_ACCESS_TOKEN

If you don't want to set environment variables explicitly, you can use the dotenv library.

Example:

1. Create .env file in the root folder of your project Example:

FB_PAGE_ACCESS_TOKEN=
FB_VERIFY_TOKEN=
APIAI_ACCESS_TOKEN=

2. Create JS file:

require('dotenv').config();
class ExampleBot extends BotStack {};

const bot = new ExampleBot('example-bot');
bot.startServer();

3. Run

node index.js

Other examples you can find in the examples folder of this repository.
