Installation
npm install i18n-postal-address
yarn add i18n-postal-address
Usage
As an ESM module (web)
Load i18n-postal-address directly from skypack (CDN).
<script type="module">
import PostalAddress from 'https://cdn.skypack.dev/i18n-postal-address'
</script>
Demo available in codepen.
On the web (self-hosted)
It's exposed through the window global object as explained below.
index.html
<head>
<script type="text/javascript" src="./postal-address.js"></script>
<script type="text/javascript" src="./app.js"></script>
</head>
app.js
var PostalAddress = window.PostalAddress.default
var myAddress = new PostalAddress()
With a bundler / Node.js
With a bundler (e.g. webpack) or in Node.js you can just require / import it.
import PostalAddress from 'i18n-postal-address'
const myAddress = new PostalAddress()
Example
The methods can be chained one after the other for a cleaner code.
const myAddressPersonal = new PostalAddress()
myAddressPersonal
.setAddress1('Rua do Pastel, 19')
.setCity('Aveiro')
.setCountry('Portugal')
.setFirstName('John')
.setHonorific('Mr.')
.setLastName('Pestana')
.setPostalCode('2700-242')
.setSecondName('Lopes')
.setFormat({
country: 'AR',
type: 'personal',
})
console.log(myAddressPersonal.toArray())
console.log(myAddressPersonal.toString())
toArray()
[ [ 'Mr.', 'John', 'Lopes' ],
[ 'Pestana' ],
[ 'Rua do Pastel, 19' ],
[ '2700-242', 'Aveiro' ],

Experimental string parsing
If you're interested in parsing a string into an object, you can use the new
experimental support for parsing addresses using some existing libraries.
However, note that these are optional and not required for the primary
functionality of this library.
libpostal
This is the most complete and comprehensive library for parsing addresses. You
need to be using the node version as it's not supported on the web.
Optional Requirements for libpostal Support
If you wish to utilize the libpostal
experimental features, follow these
steps:
- Install libpostal following their installation instructions, or
execute this script if you're on a *nix machine.
- Install node-postal as an optional dependency in your
project, after installing libpostal. This is not required for the core
functionality but only if you want to use the
libpostal
features.
Remember, these steps are optional and are only for users interested in the
experimental string parsing feature.
Experimental usage
Notice the import is slightly different, you should import this library as
i18n-postal-address/strings
.
const PostalAddress = require('i18n-postal-address/strings').default
const postalAddress = new PostalAddress()
postalAddress.fromString(
'Barboncino 781 Franklin Ave, Crown Heights, Brooklyn, NY 11238',
)
console.log(postalAddress.toString())
Barboncino 781 Franklin Ave
Crown Heights Brooklyn
NY 11238
Background
Why
The libpostal library is not available on the web.
Need to present postal addresses for different regions worldwide stored in
individual parts (company name, address, postal code, city, county, country,
...).
