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 = ; // re-request every 60sosmStream ; // re-request every 60s// callback-style interfaceosmStream ; // one-time requestosmStream ;
The stream returned uses through, so you can end it and that will also stop the run cycle.
