Component library for processing OTP profile results. Requires an instance of OTP that is accessible via JSONP requests.

$ component install conveyal/otp-profiler
$ npm install otp-profiler

For example data returned, see test/index.js.

var Profiler = require('otp-profiler');
 
// O/D points 
var od = {
  from: {
    name: 'Home',
    lat: 38.895,
    lon: -77.09
  },
  to: {
    name: 'Work',
    lat: 38.894,
    lon: -77.01
  }
};
 
// Create new instance 
var profiler = new Profiler({
  host: 'http://localhost:8080/otp-rest-servlet',
  limit: 3 // limit the number of options to profile, defaults to 3 
});
// Request a profile options 
profiler.profile(od, function(errprofile) {
  console.log(profile); // Outputs the profile of the journey 
});
// Request possible routes 
profiler.routes(function(errroutes) {
  console.log(routes); // Outputs all usable transit routes 
});

If options does not contain a profile or routes object it will retreive them automatically.

// Request a journey plan 
profiler.journey(od, function(errcallback) {
  console.log(journey); // Outputs a journey plan 
})

Converts raw JSON returned from OTP into a simpler format for use with transitive.

Helper function for asynchronously retrieving all patterns for a given profile object.

profiler.patterns({
  profile: profile,
  limit: 3
}, function(errpatterns) {
  console.log(patterns); // All used patterns for a given profile 
});

Helper function that returns all unique patterns for the first limit options in the passed in profile.
