blinktaginc/gtfs-to-html-service

A service that uses gtfs-to-html to generate HTML or PDF schedules from transit data in GTFS format.

GTFS to HTML as a Service

This project is a node.js app that runs on a server and uses GTFS-to-HTML to generate HTML or PDF schedules from transit data in GTFS format. It listens via websockets for the agency name, GTFS file location and timetable configuration and responds with a URL where the completed HTML or PDF timetables can be downloaded.

Try it out at https://run.gtfstohtml.com/.

Setup

Install dependencies

npm install

Configure

Copy .env-example to .env.

cp .env-example .env

Update the values as needed.

Running Locally

npm run dev

Connect to a websocket on localhost:3000. Use something like the Simple Websocket Client Chrome extension.

Send a websocket message with a JSON payload to localhost:3000. This JSON can include any options from gtfs-to-html except verbose, zipOutput.

{
  "agencies": [
    {
      "agency_key": "bart",
      "url": "https://transitfeeds.com/p/bart/58/latest/download"
    }
  ],
  "effectiveDate": "July 8, 2016",
  "noServiceSymbol": "—",
  "requestStopSymbol": "***",
  "showMap": true
}

The server will respond via websockets. If the timetable generation is successful, the response will include a URL where the timetables can be downloaded.

{
  "buildId":"132da383-721f-4ba3-9ab0-c979ac9e17f4",
  "status": "completed",
  "message": "Completed creating timetables for bart",
  "url": "http://localhost:3000/bart/gtfs.zip"
}

If instead there is an error while processing, the response will contain the error.

{
  "buildId":"132da383-721f-4ba3-9ab0-c979ac9e17f4",
  "status": "error",
  "message": "Error: Number of columns on line 69 does not match header"
}
