A throttleable stream, for working in the slow-lane
A throttleable stream, for working in the slow-lane; i.e. good for testing when you need things to slow down. Available in npm as slow-stream
var fs = require'fs'SlowStream = require'slow-stream'fscreateReadStream'infile' bufferSize: 64pipe maxWriteInterval: 5pipefscreateWriteStream'outfile'
Throttling is performed on a per-write basis, so in this example the
ReadStream from the file is writing 64-byte chunks at a time. The
SlowStream is only allowing them through at a rate of one per 5ms.
Back-pressure is properly applied so if you're working with properly implemented streams you shouldn't run into memory issues.
Tests can be run with
npm test. I'm more than happy to receive contributions so fork away!
