WSF for Node.js

An asynchronous client library for WSDOT Washington State Ferries (WSF) Fares, Schedule, Terminals, and Vessels REST APIs.

var Wsf = require('wsf');

var client = new Wsf({
  api_access_code: '',
  fix_dates: false
});

// Access Fares API  -- get /terminalcombo/{TripDate}/{DepartingTerminalID}/{ArrivingTerminalID}
var TripDate = '2015-10-01';
var params = [TripDate, 3, 7];
client.fares.terminalcombo(params, function(error, combo, response){
  if (!error) {
    console.log(combo);
  }
});

// Access Vessels API (no params)  -- get /vessellocations
client.vessels.vessellocations(function(error, vessels, response){
  if (!error) {
    console.log(vessels);
  }
});

// Access Vessels API (one param)  -- get /vessellocations/{VesselID}
client.vessels.vessellocations(20, function(error, vessel, response){
  if (!error) {
    console.log(vessel);
  }
});

Installation

npm install wsf

Quick Start

You will need valid WSDOT developer credentials in the form of an API Access Code. You can get these here. Submit your email address and retrieve your API Access Code.

The dates are sent from WSDOT in this format: '/Date(1441946334000-0700)/' . You can pass fix_dates: true in the options object to indiscriminately find and replace them with the Unix Epoch equivalent. The replace operation will take place after every request if enabled.

Requests

You now have the ability to make GET requests against the API via the convenience methods.

Requests can be made in this way: client[service][endpoint](params, callback) where

• service is one of ['fares','schedule','terminals','vessels']
• endpoint is a valid endpoint listed on the Fares, Schedule, Terminals, or Vessels REST API Documentation pages
• params is optional and can be omitted, or (typeof params === 'number' || typeof params === 'string' || typeof params.join === 'function') => true
• for those requests requiring params to be an array, please note that the order of the elements must match the order described in the documentation.
• the callback signature is function(error, data, response) - data is parsed JSON, and response is the raw response

You can see an example of how this is used below.

REST API

You simply need to pass the endpoint and parameters to one of convenience methods.

Example, lets get a list of vessel locations:

// Access Vessels API (no params)  -- get /vessellocations
client.vessels.vessellocations(function(error, vessels, response){
  if(error) throw error;
  console.log(vessels);  // The vessels.
  console.log(response);  // Raw response object.
});

How about an example that passes parameters? Let's grab some terminal combos:

// Access Fares API  -- get /terminalcombo/{TripDate}/{DepartingTerminalID}/{ArrivingTerminalID}
var TripDate = '2015-10-01';
var params = [TripDate, 3, 7];
client.fares.terminalcombo(params, function(error, combo, response){
  if (!error) {
    console.log(combo);
  }
});
