TFL Line Status

tfl-line-status provides a simple module to consume the TFL (Transport for London) Lines Status feed (XML) and convert/parse it in an easier form to handle with JS.

Maintained by Paolo Chiabrera.

Install

$ npm i tfl-line-status

Usage

ES6

import TflLineStatus from 'tfl-line-status';

const tflLineStatus = new TflLineStatus();

ES5

var TflLineStatus = require('tfl-line-status');

var tflLineStatus = new TflLineStatus();

API

tflLineStatus.getLines()

it returns all the line codes (including also not tube lines, such as DLR)

const lines = tflLineStatus.getLines();

/* response sample */

['B', 'C', 'CI', 'D', 'H', 'J', 'M', 'N', 'P', 'V', 'W', 'DLR', 'OVG', 'RAIL', 'TRAMS']

tflLineStatus.getLineStatus(code)

code (optional) accepted values are: ['B', 'C', 'CI', 'D', 'H', 'J', 'M', 'N', 'P', 'V', 'W', 'DLR', 'OVG', 'RAIL', 'TRAMS']

const promise = tflLineStatus.getLineStatus(code);

promise.then(function (response) {
    /* here you get the line status */
}, function (err) {
    /* too bad, something wrong happened */
});

if a valid code is passed, the promise will return the relative line status object

const promise = tflLineStatus.getLineStatus('B');

/* response sample */

{
  active: true,
  code: 'B',
  desc: 'Good Service',
  details: '',
  id: '1',
  name: 'bakerloo',
  status: 'GS'
}

if no code is provided, all line statuses will be retrieved and returned as an ordered array

const promise = tflLineStatus.getLineStatus('B');

/* response sample */

[{
  active: true,
  code: 'B',
  desc: 'Good Service',
  details: '',
  id: '1',
  name: 'bakerloo',
  status: 'GS'
}, {
  active: true,
  code: 'C',
  desc: 'Good Service',
  details: '',
  id: '2',
  name: 'central',
  status: 'GS'
}]

Notes

The core method for getting the lines status feed is memoized in order to improve the performances, the data is automatically refreshed ever 30 seconds.
