byline-interleave
Interleaved line-by-line streaming from multiple streams
It currently assumes that all input streams provide equal number of lines. The order of the lines in the consuming end is not guaranteed to be the same as the order of the input files.
Install
npm install byline-interleave
Usage
var interleave = require('byline-interleave');
var stream = interleave(
'file-1.txt',
'file-2.txt'
);
stream.on('data', function(data) {
console.log(data); // ['line 1 from file-1.txt', 'line 1 from file2.txt'] etc
});
stream.on('end', function() {
console.log('end of stream');
});
