node-GTFS loads transit data in GTFS format into a SQLite 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.

Additionally, this library can export data from the SQLite database back into GTFS (csv) format.

You can use it as a command-line tool or as a node.js module.

This library has three parts: the GTFS import script, the query methods and the GTFS export script

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 -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.

Quick Start

Command-line examples

gtfs-import --gtfsUrl http://www.bart.gov/dev/schedules/google_transit.zip

or

gtfs-import --gtfsPath /path/to/your/gtfs.zip

or

gtfs-import --gtfsPath /path/to/your/unzipped/gtfs

or

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

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

Code example

import { importGtfs } from 'gtfs';
import { readFile } from 'fs/promises';
const config = JSON.parse(
  await readFile(new URL('./config.json', import.meta.url))
);

importGtfs(config)
  .then(() => {
    console.log('Import Successful');
  })
  .catch((err) => {
    console.error(err);
  });

Example Applications

Command Line Usage

The gtfs-import command-line utility will import GTFS into SQLite3.

The gtfs-export command-line utility will create GTFS from data previously imported into SQLite3.

gtfs-import Command-line options

configPath

Allows specifying a path to a configuration json file. By default, node-gtfs will look for a config.json file in the directory it is being run from. Using a config.json file allows you specify more options than CLI arguments alone - see below.

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

gtfsPath

Specify a local path to GTFS, either zipped or unzipped.

gtfs-import --gtfsPath /path/to/your/gtfs.zip

or

gtfs-import --gtfsPath /path/to/your/unzipped/gtfs

gtfsUrl

Specify a URL to a zipped GTFS file.

gtfs-import --gtfsUrl http://www.bart.gov/dev/schedules/google_transit.zip

TypeScript Support

Basic TypeScript typings are included with this library. Please open an issue if you find any inconsistencies between the declared types and underlying code.

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. | | csvOptions | object | Options passed to csv-parse for parsing GTFS CSV files. Optional. | | exportPath | string | A path to a directory to put exported GTFS files. Optional, defaults to gtfs-export/<agency_name>. | | sqlitePath | string | A path to an SQLite database. Optional, defaults to using an in-memory database. | | verbose | boolean | Whether or not to print output to the console. Optional, defaults to true. |

agencies

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

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": [
    {
      "url": "http://countyconnection.com/GTFS/google_transit.zip"
    }
  ]
}

• Specify a download URL with custom headers:

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

• Specify a path to an unzipped GTFS file:

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

• Specify multiple agencies to be imported into the same database

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

csvOptions

{Object} Add options to be passed to csv-parse with the key csvOptions. This is an optional parameter.

For instance, if you wanted to skip importing invalid lines in the GTFS file:

    "csvOptions": {
      "skip_lines_with_error": true
    }

See full list of options.

exportPath

{String} A path to a directory to put exported GTFS files. If the directory does not exist, it will be created. Used when running gtfs-export script or exportGtfs(). Optional, defaults to gtfs-export/<agency_name> where <agency_name> is a sanitized, snake-cased version of the first agency_name in agency.txt.

sqlitePath

{String} A path to an SQLite database. Optional, defaults to using an in-memory database with a value of :memory:.

    "sqlitePath": "/dev/sqlite/gtfs"

verbose

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

{
  "agencies": [
    {
      "path": "/path/to/the/unzipped/gtfs/"
    }
  ],
  "verbose": false
}

If you want to route logs to a custom function, you can pass a function that takes a single text argument as logFunction. This can't be defined in config.json but instead passed in a config object to importGtfs(). For example:

import { importGtfs } from 'gtfs';

const config = {
  agencies: [
    {
      url: 'http://countyconnection.com/GTFS/google_transit.zip',
      exclude: ['shapes'],
    },
  ],
  logFunction: function (text) {
    // Do something with the logs here, like save it or send it somewhere
    console.log(text);
  },
};

importGtfs(config);

gtfs-import Script

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

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

Use importGtfs script in code

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

import { importGtfs } from 'gtfs';
import { readFile } from 'fs/promises';

const config = JSON.parse(
  await readFile(new URL('./config.json', import.meta.url))
);

importGtfs(config)
  .then(() => {
    console.log('Import Successful');
  })
  .catch((err) => {
    console.error(err);
  });

Configuration can be a JSON object in your code

import { importGtfs } from 'gtfs';

const config = {
  sqlitePath: '/dev/sqlite/gtfs',
  agencies: [
    {
      url: 'http://countyconnection.com/GTFS/google_transit.zip',
      exclude: ['shapes'],
    },
  ],
};

importGtfs(config)
  .then(() => {
    console.log('Import Successful');
  })
  .catch((err) => {
    console.error(err);
  });

gtfs-export Script

The gtfs-export script reads from a JSON configuration file and exports data in GTFS format from a SQLite database. Read more on setting up your configuration file.

This could be used to export a GTFS file from SQLite after changes have been made to the data in the database manually.

Make sure to import GTFS data into SQLite first

Nothing will be exported if there is no data to export. See the GTFS import script.

Run the gtfs-export script from Command-line

gtfs-export

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

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

Command Line options

Specify path to config JSON file

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

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

Show help

Show all command line options

gtfs-export --help

Use exportGtfs script in code

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

import { exportGtfs } from 'gtfs';

const config = {
  sqlitePath: '/dev/sqlite/gtfs',
  agencies: [
    {
      url: 'http://countyconnection.com/GTFS/google_transit.zip',
      exclude: ['shapes'],
    },
  ],
};

exportGtfs(config)
  .then(() => {
    console.log('Export Successful');
  })
  .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 optional arguments: query, fields and sortBy.

Query

For example, to get a list of all routes with just route_id, route_short_name and route_color sorted by route_short_name:

import { openDb, getRoutes } from 'gtfs';
import { readFile } from 'fs/promises';
const config = JSON.parse(
  await readFile(new URL('./config.json', import.meta.url))
);

const db = await openDb(config);
const routes = await getRoutes(
  {},
  ['route_id', 'route_short_name', 'route_color'],
  [['route_short_name', 'ASC']]
);

To get a list of all trip_ids for a specific route:

import { openDb, getTrips } from 'gtfs';
import { readFile } from 'fs/promises';
const config = JSON.parse(
  await readFile(new URL('./config.json', import.meta.url))
);

const db = await openDb(config);
const trips = await getTrips(
  {
    route_id: '123',
  },
  ['trip_id']
);

To get a few stops by specific stop_ids:

import { openDb, getStops } from 'gtfs';
import { readFile } from 'fs/promises';
const config = JSON.parse(await readFile(new URL('./config.json', import.meta.url)));
