Usage

tflJourneyPlanner = require('tfl-journey-planner');
 
// Specify locations in this format 
locations = {
  to: {lat: 51.5002452, lng: 0.0035842},
  from: {lat: 51.5131652, lng: -0.0905267}

tflJourneyPlanner(locations, options, function(results){
  console.log(results); // Do awesome stuff with the TFL results! 
});

Locations

Locations can either be specified like:

locations = {
  to: {lat: 51.5002452, lng: 0.0035842},
  from: {lat: 51.5131652, lng: -0.0905267}
}

or with their text value

locations = {
  to: 'Aldgate East',
  from: 'London Bridge'
};

However, using text values will more than likley have many matches, so your response may not be as you'd planned.

Authenticating

Authentication is not required any longer or tfl requests. If you do need to authenticate then you can sign up for an API key at https://api-portal.tfl.gov.uk/signup Create a JSON object similar to the one below

var config = {};

tfl = {
    appId: 'xxxxxxxx',
    appKey: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
};

module.exports = config;

If you have put your credentials in a seperate file like above you can include them in your main JavaScript file the normal way

var credentials = require('../helpers/config');

Also don't forget to add the file with your API keys to .gitignore
