Throttle object / chunk streams using back pressure
npm install chunk-brake
Uses back pressure to throttle a stream to run at a maximum speed of X times per second
Like brake, but it throttles chunks instead of bytes. This means it works well as an objectMode transform.
The constructor accepts two parameters:
+ throttle The throttle rate in ms, i.e. the minimum miliseconds which must pass between each chunk push
+ options Optional options object which is passed through to the underlying Transform constructor
``Javascript
var chunkBrake = require('chunk-brake')
var brake = chunkBrake(500, {objectMode: true})
brake.pipe(someObjectStreamReader)
for (var i = 0; i < 500; i++)
brake.write({id: i, msg: 'all the sun that shines B)'})
``
Note that this currently doesn't do anything super special to help ensure accuracy, i.e. to ensure that yes, chunks are in fact coming in at X times a second with relative guarantee. Tests check for accuracy within 2 ms FWIW
