choppa
Through stream that chops a stream into specified size chunks. The main purpose of the module is to test if your stream behaves the same way when it receives different sized chunks.
Install
npm install choppa
Usage
var choppa = require('choppa');
readableStream.pipe(choppa()).pipe(writableStream); // writable stream will receive 1 byte at a time.
readableStream.pipe(choppa(5)).pipe(writableStream); // writable stream will receive 5 byte at a time.
//You can also pass a 0 to the choppa constructor and the size of each chunk will be random
readableStream.pipe(choppa(0)).pipe(writableStream);
