npm install network-railThis is a node package for interacting with the Network Rail data feeds.
It comes with a tool for accessing this data directly via the command line, or can be used within your own projects.
Install with:
``
$ npm install network-rail
_move binary to /usr/local/bin ?_
...
Require the network-rail package as usual:
`js`
var rail = require('network-rail');
You must start by connecting to the feeds service, you should first register with Network Rail, then use your username and password to connect.
`js`
rail.feeds.connect(username, password);
Once connected to the datafeeds you can then listen to the stream of data as it is received. You can either listen directly to the feed and get the raw data as it comes back, or use one of the provided transformers.
`js
// raw data
rail.feeds.listen('TRAIN_MVT_ALL_TOC', null, function(body, headers) {
body.forEach(function(message) {
console.log('Type:', message.header.msg_type); // e.g. 0001
console.log('Train:', message.body.train_id);
console.log('Timestamp:', message.body.actual_timestamp);
console.log('Company:', message.body.toc_id);
console.log('Delay:', message.body.timetable_varation');
});
});
// formatted
rail.movements.listen(function(movements) {
Object.keys(movements).forEach(function(type) {
console.log(type); // e.g. activations
movements[type].forEach(function(movement) {
console.log('\tTrain:', movement.trainID);
console.log('\t\tTimestamp:', movement.timestamp);
console.log('\t\tCompany:', movement.company);
console.log('\t\tDelay:', movement.timetableVariation, 'minutes');
});
});
});
