# speedometerSpeed measurement in Javascript```npm install speedometer```## Usage``` jsvarspeedometer=require('speedometer')varfs=require('fs')// Let's measure how fast we can read from /dev/urandomvarspeed=speedometer()varstream=fs.createReadStream('/dev/urandom')stream.on('data',function(data){// Simply call speed with the amount of bytes transferredvarbytesPerSecond=speed(data.length)console.log(bytesPerSecond+' bytes/second')})```You can always get the current speed by calling `speed()`.Per default `speedometer` uses a 5 second buffer.To change this simply pass another value to the constructor``` jsvarspeed=speedometer(20)// uses a 20s buffer instead```## LicenseMIT
