#!/bin/bash
npm install openstreetmap-stream; curl -s http://planet.osm.org/pbf/planet-latest.osm.pbf | node -e "var osm = require('openstreetmap-stream'); process.stdin.pipe(osm.parser()).pipe(osm.stringify).pipe(process.stdout);";

I've written up some docs: https://github.com/geopipes/openstreetmap-stream which show a few ways you can integrate this in to a node app; or you can just use unix pipes to send it onward to your language of choice.
