   }
}
*/

// Invalid tracking number
const tracking = getTracking('9261292700768711948020'); // undefined

Search text for tracking numbers

import { findTracking } from 'ts-tracking-number';

const text = `A good number is 9400111202555842332669, but 9261292700768711948020 is bad and
  7112 3456 7891 2345 6787 is also good`;

const tracking = findTracking(text);

[
  {
    name: 'FedEx Express (12)',

  }
]

Specifying Desired Courier

Optionally you may specify which carrier(s) to retrieve in either getTracking or findTracking by passing an array of couriers to the function.

Filterable couriers are amazon, dhl, fedex, ontrac, s10, ups, usps

import { getTracking, findTracking, ups, fedex } from 'ts-tracking-number';

const fedexNumber = '986578788855';

// This will ensure we're verifying for FedEx only
getTracking(fedexNumber, [fedex]);

// This will be undefined
getTracking(fedexNumber, [ups]);

// Search text for only fedex or ups numbers
findTracking('A bunch of text...', [fedex, ups]);
