Freeform Street Address Parser

addressit

AddressIt is a freeform street address parser, that is designed to take a piece of text and convert that into a structured address that can be processed in different systems.

The focal point of addressit is on the street parsing component, rather than attempting to appropriately identify various states, counties, towns, etc, as these vary from country to country fairly dramatically. These details are instead put into a generic regions array that can be further parsed based on your application needs.

Example Usage

The following is a simple example of how address it can be used:

var addressit = require('addressit');
 
// parse a made up address, with some slightly tricky parts 
var address = addressit('Shop 8, 431 St Kilda Rd Melbourne');

The address object would now contain the following information:

{ text: '8/431 ST KILDA RD MELBOURNE',
  parts: [],
  unit: 8,
  country: undefined,
  number: 431,
  street: 'ST KILDA RD',
  regions: [ 'MELBOURNE' ] }

For more examples, see the tests.

Reference

addressit(input, opts?)

Run the address parser for the given input. Optional opts can be supplied if you want to override the default (EN) parser.

Address

Address#_extractStreetParts(startIndex)

This function is used to extract from the street type match index back to the street number and possibly unit number fields.

The function will start with the street type, then also grab the previous field regardless of checks. Fields will continue to be pulled in until fields start satisfying numeric checks. Once positive numeric checks are firing, those will be brought in as building / unit numbers and once the start of the parts array is reached or we fall back to non-numeric fields then the extraction is stopped.

Address#clean

The clean function is used to clean up an address string. It is designed to remove any parts of the text that preven effective parsing of the address string.

Address#extract(fieldName, regexes)

The extract function is used to extract the specified field from the raw parts that have previously been split from the input text. If successfully located then the field will be updated from the parts and that part removed from the parts list.

Address#extractStreet

This function is used to parse the address parts and locate any parts that look to be related to a street address.

Address#finalize

The finalize function takes any remaining parts that have not been extracted as other information, and pushes those fields into a generic regions field.

Address#split

Split the address into it's component parts, and remove any empty parts

Address#toString

Convert the address to a string representation
