botbuilder-wit

botbuilder-wit

Node.js module that provides Wit.ai NLP integration for the Microsoft Bot Builder SDK.

Installation

npm install --save botbuilder-wit

Usage

This package does not work with Wit.ai's Story feature. This is by design. That doesn't mean you can't use it entirely, just not in combination with the IntentDialog that uses the WitRecognizer.

const { IntentDialog } = require('botbuilder');
const WitRecognizer = require('botbuilder-wit');
const recognizer = new WitRecognizer('Wit.ai_access_token');
const intents = new IntentDialog({recognizers: [recognizer]});

intents.matches('intent.name', (session, args) => {...});
intents.onDefault(session => {...});

bot.dialog('/', intents)

Using Entities

You can use the utility class EntityRecognizer to parse & resolve common entities.

// Inside your dialog handler that receives the session and arguments object
const { EntityRecognizer } = require('botbuilder');
const location = EntityRecognizer.findEntity(args.entities, 'location')

Using the Wit.ai client

You can still use the Wit.ai client directly by accessing the witClient property of the instantiated WitRecognizer.

const recognizer = new WitRecognizer('Wit.ai_access_token');
const witClient = recognizer.witClient;

Recompiling the TypeScript source

If you want to recompile the source, you will need to make sure the node-wit dependency has a type definitions file in its root directory. At the moment, they're not yet available in the DefinitelyTyped repository. However, in the resources directory you'll find a minimalistic version that will do the job.
