A simple javascript library to create a custom array of US States

Usa States

A simple javascript library to aid with the creation of your custom array of US States.

Installation

npm install usa-states

Then include the library in your project with either

var UsaStates = require('usa-states').UsaStates;

or

<script src="/js/usa-states.js"></script>

Usage

To quickly get a simple array of US States objects

var usStates = new UsaStates();
console.log(usStates.states);

Outputs

{
    name: "Alabama",
    abbreviation: "AL",
    territory: false,
    capital: "Montgomery",
    contiguous: true
},
{
    name: "Alaska",
    abbreviation: "AK",
    territory: false,
    capital: "Juneau",
    contiguous: false
},
...(other states omitted for brevity)
{
    name: "Wyoming",
    abbreviation: "WY",
    territory: false,
    capital: "Cheyenne",
    contiguous: true
}

You can optionally filter or add to the list of US States

var lowerFourtyEight = new UsaStates({contiguousOnly: true});
console.log('Lower 48 states only', lowerFourtyEight.states);

var statesAndTerritories = new UsaStates({includeTerritories: true}); 
console.log('All states including territories', statesAndTerritories.states);

You can also manually exclude one or more using any of the alias selectors

var allStatesExceptDCandWY = new UsaStates({exclude: ['DC', 'Wyoming']});

You can get them as an array of strings using an alias selector (full list of alias selectors below)

var usStates = new UsaStates(myOptionalFilterSettings);
var statesAbbreviation = usStates.arrayOf('abbreviations');
var statesNames = usStates.arrayOf('names');
console.log(statesAbbreviation);
console.log(statesNames);

Outputs

["AL", "AK", ... , "WY"]
["Alabama", "Alaska", ..., "Wyoming"]

You can also get them as an array of custom objects using the alias selectors If you want an alias ignored just append a '$' character to the desired location (note: you can change this ignore character in your filter config, see below)

var usStates = new UsaStates(myOptionalFilterSettings);
var myCustomStates = usStates.format({
    name: 'abbreviation',
    $abbreviation: 'abbr', // alternate alias 'abbr', see all below
    abbr: '$name',
    $capital: 'c',
});
console.log(myCustomStates);

Outputs

{
    Alabama: "AL",
    abbreviation: "AL",
    AL: "name",
    capital: "Mobile"
},
{
    Alaska: "AK",
    abbreviation: "AK",
    AK: "name",
    capital: "Juneau"
},
...
{
    Wyoming: "WY",
    abbreviation: "WY",
    WY: "name",
    capital: "Cheyenne"
}
