Import and Export GTFS transit data into SQLite. Query or change routes, stops, times, fares and more.

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.

The library also supports importing GTFS-Realtime data into the same database. In order to keep the realtime database fresh, it uses SQLITE REPLACE which makes it very effective.

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

This library has four parts: the GTFS import script, GTFS export script and GTFS-Realtime update script and the query methods

Installation

To use this library as a command-line utility, install it globally with npm:

npm install gtfs -g

This will add the gtfs-import and gtfs-export scripts to your path.

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

npm install gtfs

	GTFS-to-HTML uses node-gtfs for downloading, importing and querying GTFS data. It provides a good example of how to use this library and is used by over a dozen transit agencies to generate the timetables on their websites.
	GTFS-to-geojson 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.
	GTFS-to-chart generates a stringline chart in D3 for all trips for a specific route using data from an agency's GTFS. It uses node-gtfs for downloading, importing and querying GTFS data.
	GTFS Accessibility Validator checks for accessiblity-realted fields and files and flags any issues. It uses node-gtfs for downloading, importing and querying GTFS data.
	GTFS-Text-to-Speech app tests GTFS stop name pronunciation for text-to-speech. It uses node-gtfs for loading stop names from GTFS data.
	Transit Departures Widget creates a realtime transit departures widget from GTFS and GTFS-Realtime data.
	GTFS-to-Blocks reads transit data from GTFS and exports all trip segments sorted by block_id and their departure times in CSV format.

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.

$3

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.

- Specify a url to download GTFS:

`json
{
"agencies": [
{
"url": "https://www.bart.gov/dev/schedules/google_transit.zip"
}
]
}
`

- Specify a download URL with custom headers using the headers field:

`json
{
"agencies": [
{
"url": "https://www.bart.gov/dev/schedules/google_transit.zip",
"headers": {
"Content-Type": "application/json",
"Authorization": "bearer 1234567890"
}
}
]
}
`

- Specify a path to a zipped GTFS file:

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

- Specify a path to an unzipped GTFS file:

`json
{
"agencies": [
{
"path": "/path/to/the/unzipped/gtfs/"
}
]
}
`

- If you don't want all GTFS files to be imported, you can specify an array of files to exclude. This can save a lot of time for larger GTFS.

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

- Specify urls for GTFS-Realtime updates. realtimeAlerts, realtimeTripUpdates and realtimeVehiclePositions fields accept an object with a url and optional headers field to specify HTTP headers to include with the request, usually for authorization purposes.

`json
{
"agencies": [
{
"url": "https://www.bart.gov/dev/schedules/google_transit.zip",
"realtimeAlerts": {
"url": "https://api.bart.gov/gtfsrt/alerts.aspx",
"headers": {
"Authorization": "bearer 123456789"
}
},
"realtimeTripUpdates": {
"url": "https://api.bart.gov/gtfsrt/tripupdate.aspx",
"headers": {
"Authorization": "bearer 123456789"
}
},
"realtimeVehiclePositions": {
"url": "https://api.bart.gov/gtfsrt/vehiclepositions.aspx",
"headers": {
"Authorization": "bearer 123456789"
}
}
}
]
}
`

- Specify multiple agencies to be imported into the same database

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

- When importing multiple agencies their IDs may overlap. Specify a prefix to be added to every ID field to maintain uniqueness.

`json
{
"agencies": [
{
"path": "/path/to/the/gtfs.zip",
"prefix": "A"
},
{
"path": "/path/to/the/othergtfs.zip",
"prefix": 10000
}
]
}
`

$3

{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:

`json
"csvOptions": {
"skip_lines_with_error": true
}
`

See full list of options.

$3

{Database Instance} When passing configuration to importGtfs in javascript, you can pass a db parameter with an existing database instance. This is not possible using a json configuration file Optional.

`js
// Using better-sqlite3 to open database
import { importGtfs } from 'gtfs';
import Database from 'better-sqlite3';

const db = new Database('/path/to/database');

importGtfs({
agencies: [
{
path: '/path/to/the/unzipped/gtfs/',
},
],
db: db,
});
`

`js
// Using openDb from node-gtfs to open database
import { importGtfs, openDb } from 'gtfs';

const db = openDb({
sqlitePath: '/path/to/database',
});

importGtfs({
agencies: [
{
path: '/path/to/the/unzipped/gtfs/',
},
],
db: db,
});
`

$3

{Integer} A number of milliseconds to wait when downloading GTFS before throwing an error. Optional, defaults to 30000 (30 seconds).

`json
{
"agencies": [
{
"path": "/path/to/the/unzipped/gtfs/"
}
],
"downloadTimeout": 30000
}
`

$3

{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/ where is a sanitized, snake-cased version of the first agency_name in agency.txt.

`json
{
"agencies": [
{
"path": "/path/to/the/unzipped/gtfs/"
}
],
"exportPath": "~/path/to/export/gtfs"
}
`

$3

{Integer} Amount of time in seconds to allow GTFS-Realtime data to be stored in database before allowing to be deleted. Defaults to 0 (old GTFS-Realtime is deleted immediately when new data arrives). Note that if new data arrives for the same trip update, vehicle position or service alert before the expiration time, it will overwrite the existing data. The gtfsRealtimeExpirationSeconds only affects when data is deleted.

`json
{
"agencies": [
{
"url": "https://www.bart.gov/dev/schedules/google_transit.zip",
"realtimeAlerts": {
"url": "https://api.bart.gov/gtfsrt/alerts.aspx"
},
"realtimeTripUpdates": {
"url": "https://api.bart.gov/gtfsrt/tripupdate.aspx"
},
"realtimeVehiclePositions": {
"url": "https://api.bart.gov/gtfsrt/vehiclepositions.aspx"
}
}
],
"gtfsRealtimeExpirationSeconds": false
}
`

$3

{Boolean} If you don't want node-GTFS to throw an error when it encounters a duplicate id on GTFS import. If true, it will skip importing duplicate records where unique constraints are violated, such astrip_id, stop_id, calendar_id. Useful if importing GTFS from multiple sources into one SQlite database that share routes or stops. Defaults to false.

`json
{
"agencies": [
{
"path": "/path/to/the/unzipped/gtfs/"
}
],
"ignoreDuplicates": false
}
`

$3

{Boolean} Controls error handling behavior during GTFS import. When true, the import process will continue even when encountering errors, logging them instead of stopping execution. Defaults to false.

When enabled, ignoreErrors will:
- Continue processing other GTFS files when one file fails
- Log error messages instead of throwing exceptions
- Skip problematic records within files while importing valid ones
- Handle various error types including:
- Invalid CSV data or malformed records
- JSON parsing errors (for GeoJSON files)
- Database constraint violations
- File read/write errors
- GTFS-Realtime API failures

Use cases:
- Importing from multiple GTFS sources where some may have data quality issues
- Processing large datasets where minor errors shouldn't halt the entire import
- Development/testing scenarios where you want to see all errors at once

⚠️ Important considerations:
- Errors are logged but not thrown, so you may miss critical data issues
- Partial imports may result in incomplete or inconsistent data
- Consider using the exclude config option to skip problematic files entirely instead of ignoring errors

`json
{
"agencies": [
{
"path": "/path/to/the/unzipped/gtfs/"
}
],
"ignoreErrors": true
}
`

$3

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

`json
"sqlitePath": "/tmp/gtfs.sqlite"
`

$3

{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.

`json
{
"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:

`js
import { importGtfs } from 'gtfs';

const config = {
agencies: [
{
url: 'https://www.bart.gov/dev/schedules/google_transit.zip',
exclude: ['shapes'],
},
],
logFunction: function (text) {
// Do something with the logs here, like save it or send it somewhere
console.log(text);
},
};

await 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.

$3

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

$3

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

`js
import { importGtfs } from 'gtfs';
import { readFile } from 'fs/promises';
import path from 'node:path';

const config = JSON.parse(
await readFile(path.join(import.meta.dirname, 'config.json'), 'utf8')
);

await importGtfs(config);
`

Configuration can be a JSON object in your code

`js
import { importGtfs } from 'gtfs';

const config = {
sqlitePath: '/tmp/gtfs.sqlite',
agencies: [
{
url: 'https://www.bart.gov/dev/schedules/google_transit.zip',
exclude: ['shapes'],
},
],
};

await importGtfs(config);
`

gtfsrealtime-update Script

The gtfsrealtime-update script requests GTFS-Realtime data and importings into a SQLite database. GTFS-Realtime data can compliment GTFS Static data. Read more about GTFS-Realtime configuration.

$3

gtfsrealtime-update

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

gtfsrealtime-update --configPath /path/to/your/custom-config.json

$3

Use updateGtfsRealtime() in your code to run an update of a GTFS-Realtime data specified in a config.json file.

`js
import { updateGtfsRealtime } from 'gtfs';
import { readFile } from 'fs/promises';
import path from 'node:path';

const config = JSON.parse(
await readFile(path.join(import.meta.dirname, 'config.json'), 'utf8')
);

await updateGtfsRealtime(config);
`

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.

$3

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

$3

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

$3

#### 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

$3

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

`js
import { exportGtfs } from 'gtfs';

const config = {
sqlitePath: '/tmp/gtfs.sqlite',
agencies: [
{
url: 'https://www.bart.gov/dev/schedules/google_transit.zip',
exclude: ['shapes'],
},
],
};

await exportGtfs(config);
`

Query Methods

This library includes many methods you can use in your project to query GTFS data. In addition to standard static GTFS, node-gtfs supports the following extensions to GTFS:

- GTFS-Realtime - Realtime alerts, vehicle positions and predictions
- GTFS-Ride - Passenger counts
- Operational Data Standard (ODS) - Deadheads and personnel info
- GTFS-Timetables - Information for creating human-readable timetables

There are also methods for retrieving stops and shapes in geoJSON format.

Most query methods accept three optional arguments: query, fields, sortBy and options.

For more advanced queries, you can use advancedQuery or raw SQL queries using query method from better-sqlite3.

$3

To use any of the query methods, first open the database using openDb before making any queries:

`js
import { openDb } from 'gtfs';
import { readFile } from 'fs/promises';
import path from 'node:path';

const config = JSON.parse(
await readFile(path.join(import.meta.dirname, 'config.json'), 'utf8')
);

const db = openDb(config);
`

If you no longer need a database (especially if using an in-memory database) you can use closeDb:

`js
import { closeDb, openDb } from 'gtfs';
const db = openDb(config);

// Do some stuff here

// Close database connection when done.
closeDb(db);
`

$3

You can use deleteDb to delete a sqlite3 database from the filesystem.

`js
import { deleteDb, openDb } from 'gtfs';
const db = openDb(config);

// Do some stuff here

// Delete the database
deleteDb(db);
`

$3

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

`js
import { closeDb, openDb, getRoutes } from 'gtfs';
import { readFile } from 'fs/promises';
import path from 'node:path';

const config = JSON.parse(
await readFile(path.join(import.meta.dirname, 'config.json'), 'utf8')
);

const db = openDb(config);
const routes = getRoutes(
{}, // No query filters
['route_id', 'route_short_name', 'route_color'], // Only return these fields
[['route_short_name', 'ASC']], // Sort by this field and direction
{ db: db }, // Options for the query. Can specify which database to use if more than one are open
);

closeDb(db);
`

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

`js
import { closeDb, openDb, getTrips } from 'gtfs';
import { readFile } from 'fs/promises';
import path from 'node:path';

const config = JSON.parse(
await readFile(path.join(import.meta.dirname, 'config.json'), 'utf8')
);

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

closeDb(db);
`

To get a few stops by specific stop_ids:

`js
import { closeDb, openDb, getStops } from 'gtfs';
import { readFile } from 'fs/promises';
import path from 'node:path';

const config = JSON.parse(
await readFile(path.join(import.meta.dirname, 'config.json'), 'utf8')
);
const db = openDb(config);
const stops = getStops(
{
stop_id: [
'123',
'234'
'345'
]
}
);

closeDb(db);
`

* whose stoptimes occur after midnight (i.e., times greater than 24:00:00
* in GTFS, such as 25:15:00 for 1:15 AM the next day).
*
* To retrieve all stoptimes for a calendar date including those from
