$ npm install split-transform-stream
A combination of through2 and split with a straightforward interface.
splitStream(inputStream, write, [end], [splitText])
returns a stream
var readStream = require('fs').createReadStream(__filename, 'utf8');
var splitStream = require('./index');
var write = function(line, encoding, next) {
this.push(line.split(' ').reverse().join(' '));
next();
};
// emitting lines in reverse
splitStream(readStream, write).on('data', function(data) {
console.log(data);
}).on('error', function(err) {
if (err) { throw err; }
}).on('end', function() {
console.log('done');
});
