    OSM Stream

    Uses the Overpass API for Augmented Diffs, loads data with CORS and exposes a stream.

    using

    Without browserify: copy osmstream.js. That works as an osmStream global and with UMD.

    With browserify npm install osm-stream

    api

    s.once(function(err, data) { }, [bbox])

    Get one batch of changes right now.

    s.run(function(err, stream), duration, [dir], [bbox])

    duration is how long between runs: default 1 minute

    dir is direction: either 1, the default, or -1 for rewind.

    s.runFn(function(err, stream), duration, [dir], [bbox])

    Same as .run but instead of returning a stream that pipes objects, calls the callback once per object.

    duration is how long between runs: default 1 minute

    dir is direction: either 1, the default, or -1 for rewind.

    example

    var osmStream = require('osm-stream');
     
    // re-request every 60s
    osmStream
        .run(function(err, stream) {
            stream.on('data', function(d) {
                console.log(d);
            });
        });
     
    // re-request every 60s
    // callback-style interface
    osmStream
        .runFn(function(err, data) {
            // ...
        });
     
    // one-time request
    osmStream
        .once(function(err, d) {
            console.log(d);
        });

    The stream returned uses through, so you can end it and that will also stop the run cycle.
