GTFS node.js client

Node-GTFS

node-GTFS loads transit data in GTFS format into a MongoDB database and provides some methods to query for agencies, routes, stops, times, fares, calendars and other GTFS data. It also offers spatial queries to find nearby stops, routes and agencies and can convert stops and shapes to geoJSON format.

This library has two parts: the GTFS import script and the query methods.

Example Application

The GTFS-to-HTML app uses node-gtfs for downloading, importing and querying GTFS data. It provides a good example of how to use this library.

The GTFS-to-geojson app creates geoJSON files for transit routes for use in mapping. It uses node-gtfs for downloading, importing and querying GTFS data. It provides a good example of how to use this library.

Installation

If you would like to use this library as a command-line utility, you can install it globally directly from npm:

npm install gtfs mongoose -g

If you are using this as a node module as part of an application, you can include it in your project's package.json file.

Note: Mongoose is a peer dependency of node-gtfs, so when installing globally be sure to install mongoose as well. If you are writing a application that uses node-gtfs as a dependency, then you'll need to include mongoose as a dependency in your project's package.json.

Command-line example

gtfs-import [--configPath /path/to/your/custom-config.json] [--skipDelete]

Code example

const gtfs = require('gtfs');
const mongoose = require('mongoose');
const config = require('./config.json');

mongoose.connect(config.mongoUrl, {useNewUrlParser: true});

gtfs.import(config)
.then(() => {
  console.log('Import Successful');
  return mongoose.connection.close();
})
.catch(err => {
  console.error(err);
});

---

Configuration

Copy config-sample.json to config.json and then add your projects configuration to config.json.

cp config-sample.json config.json

option	type	description
agencies	array	An array of GTFS files to be imported.
mongoUrl	string	The URL of the MongoDB database to import to.
verbose	boolean	Whether or not to print output to the console.
skipDelete	boolean	Whether or not to skip deleting existing data from the database.

Agencies

Specify the GTFS files to be imported in an agencies array. GTFS files can be imported via a url or a local path.

Each file needs an agency_key, a short name you create that is specific to that GTFS file. For GTFS files that contain more than one agency, you only need to list each GTFS file once in the agencies array, not once per agency that it contains.

To find an agency's GTFS file, visit transitfeeds.com. You can use the URL from the agency's website or you can use a URL generated from the transitfeeds.com API along with your API token.

• Specify a download URL:

{
  "agencies": [
    {
      "agency_key": "county-connection",
      "url": "http://countyconnection.com/GTFS/google_transit.zip"
    }
  ]
}

• Specify a download URL with custom headers:

{
  "agencies": [
    {
      "agency_key": "county-connection",
      "url": "http://countyconnection.com/GTFS/google_transit.zip",
      "headers: {
        "Content-Type": "application/json",
        "Authorization": "bearer 1234567890"
      },
    }
  ]
}

• Specify a path to a zipped GTFS file:

{
  "agencies": [
    {
      "agency_key": "myAgency",
      "path": "/path/to/the/gtfs.zip"
    }
  ]
}

• Specify a path to an unzipped GTFS file:

{
  "agencies": [
    {
      "agency_key": "myAgency",
      "path": "/path/to/the/unzipped/gtfs/"
    }
  ]
}

• Exclude files - if you don't want all GTFS files to be imported, you can specify an array of files to exclude.

{
  "agencies": [
    {
      "agency_key": "myAgency",
      "path": "/path/to/the/unzipped/gtfs/",
      "exclude": [
        "shapes",
        "stops"
      ]
    }
  ]
}

• Optionally specify a proj4 projection string to correct poorly formed coordinates in the GTFS file

{
  "agencies": [
    {
      "agency_key": "myAgency",
      "path": "/path/to/the/unzipped/gtfs/",
      "proj": "+proj=lcc +lat_1=46.8 +lat_0=46.8 +lon_0=0 +k_0=0.99987742 +x_0=600000 +y_0=2200000 +a=6378249.2 +b=6356515 +towgs84=-168,-60,320,0,0,0,0 +pm=paris +units=m +no_defs"
    }
  ]
}

MongoDB URI

Add the MongoDB URI to config.json with the key mongoUrl. Running locally, you could use something like mongodb://localhost:27017/gtfs.

{
  "mongoUrl": "mongodb://localhost:27017/gtfs",
  "agencies": [
    {
      "agency_key": "myAgency",
      "path": "/path/to/the/unzipped/gtfs/"
    }
  ]
}

Logging

If you don't want the import script to print any output to the console, you can set verbose to false. Defaults to true.

{
  "mongoUrl": "mongodb://localhost:27017/gtfs",
  "agencies": [
    {
      "agency_key": "localAgency",
      "path": ""/path/to/the/unzipped/gtfs/"
    }
  ],
  "verbose": false
}

Deleting existing data

If you don't want the import script to delete all existing data from the database with the same agency_key, you can set skipDelete to true. Defaults to false.

{
  "mongoUrl": "mongodb://localhost:27017/gtfs",
  "agencies": [
    {
      "agency_key": "localAgency",
      "path": ""/path/to/the/unzipped/gtfs/"
    }
  ],
  "skipDelete": true
}

gtfs-import Script

The gtfs-import script reads from a JSON configuration file and imports the GTFS files specified to a MongoDB database. Read more on setting up your configuration file.

Make sure MongoDB is running

If you want to run this locally, make sure MongoDB in installed and running.

mongod

Run the gtfs-import script from Command-line

gtfs-import

By default, it will look for a config.json file in the project root. To specify a different path for the configuration file:

gtfs-import --configPath /path/to/your/custom-config.json

Command Line options

Skip Delete

By default, the import script will delete any existing data with the same agency_key from your database. If you don't want this to happen, pass the --skipDelete flag

gtfs-import --skipDelete

Specify path to config JSON file

You can specify the path to a config file to be used by the import script.

gtfs-import --configPath /path/to/your/custom-config.json

Show help

Show all command line options

gtfs-import --help

Use GTFS import script in code

Use gtfs.import() in your code to run an import of a GTFS file specified in a config.json file.

const gtfs = require('gtfs');
const mongoose = require('mongoose');
const config = require('config.json');

mongoose.connect(config.mongoUrl, {useNewUrlParser: true});

gtfs.import(config)
.then(() => {
  console.log('Import Successful');
  return mongoose.connection.close();
})
.catch(err => {
  console.error(err);
});

Configuration can be a JSON object in your code

const gtfs = require('gtfs');
const mongoose = require('mongoose');
const config = {
  mongoUrl: 'mongodb://localhost:27017/gtfs',
  agencies: [
    {
      agency_key: 'county-connection',
      url: 'http://countyconnection.com/GTFS/google_transit.zip',
      exclude: [
        'shapes'
      ]
    }
  ]
};

mongoose.connect(config.mongoUrl, {useNewUrlParser: true});

gtfs.import(config)
.then(() => {
  console.log('Import Successful');
  return mongoose.connection.close();
})
.catch(err => {
  console.error(err);
});

Query Methods

This library includes many methods you can use in your project to query GTFS data. These methods return promises.

Most methods accept three arguments: query, projection and options. projection and options are optional and are passed to the mongoose find query.

Query

For example, to get a list of all agencies within 5 miles of a specific point:

gtfs.getAgencies({
  within: {
    lat: 37.7749,
    lon: -122.4194,
    radius: 5
  }
})
.then(agencies => {
  // Do something with the array of `agencies`
})
.catch(err => {
  // Be sure to handle errors here
});

Projection

By default, projection is set to exclude mongo _id. projection allows specifying which fields you would like returned. For instance:

// Gets all agencies but limits results to only include `agency_name` and `agency_lang`.
gtfs.getAgencies({}, {
  _id: 0,
  agency_name: 1,
  agency_lang: 1
})
.then(agencies => {
  // each Agency only has `agency_name` and `agency_lang`
});

Options

Mongoose allows numerous options to be set on the query. You can specify things like sort and limit using the options parameter. By default, options is set to lean: true to return a plain javascript object.

// Gets all agencies sorted by `agency_name`
gtfs.getAgencies({}, {}, {
  sort: {agency_name: 1}
})
.then(agencies => {

});

Setup

Include this library.

var gtfs = require('gtfs');

Connect to mongo via mongoose.

const mongoose = require('mongoose');
mongoose.connect('YOUR-MONGODB-URI');

If you are running locally, your MongoDB uri might be something like:

mongodb://localhost:27017/gtfs

You probably want to use the same value used in your configuration JSON file for importing GTFS.
