Package Exports
- watsonhelper
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (watsonhelper) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Background
A recent IBM Watson customer was exploring Watson conversation api. For the customer extraction of phone numbers and email was a key usecase. This data needs to be captured during the conversation. Hence to assist the customer I wrote this library. This library now can help customers with similar usecase extract their set of data usually expressed in conversations or personal blogs. I have released the first version that can address 3 key usecases. Few other key usecases are in pipeline.
Examples
Basic example
Extraction of one or more phone numbers, email or custom data(like invoiceno, ticketid, purchaseordernumber, UID etc ) from a user supplied text.
var helper = require('watsonhelper');
var phonelist = helper.phoneextractor("I am moving to hyderabad and my mobile number is +919538099898, You can also call me at 08042227967");
var email = helper.emailextractor("I am moving to US and my email id is shunandi@gmail.com, You can also email me at shubhradeepnandi@gmail.com");
var invoiceno = helper.extractor("<Extracting What>", "Your invoice is generated it is inv1105576", <REGEX STRING>);Limitations
This software cannot capture every single combination imaginable. Especially number-to-letter substitution is difficult to detect e.g:
- O4!4.Ol2;341 (= 0414 012 341)
In my experience very few users write their phone number this way. From a programming point of view it would be possible to cover for edge cases like above, but I have chosen not to.
