Simple processing of Readables

Consume a node Readable stream in chunks using an async process function. This is especially useful for implementing stream based parsers, or consuming objectMode streams.

Usage

var streamprocess = require('streamprocess');

var r = fs.createReadStream(…);

streamprocess(r, function(buf, cb) {
  // do your thing
  …

  // signal that you are done
  setImmediate(cb);
});

Installation

npm install streamprocess

Methods

There is just one method, returned directly from the module import.

streamprocess(readable, processFn, [doneCb])

Consume readable by retrieving buffers one at a time, passing them to processFn(buf, cb).

A doneCb(err) will be called after the stream has ended or encountered an error.
