read-lines

Read big files, line by line.

npm install read-lines

Usage

The module emits the first line and then stops until you call the
next() callback, in this way you can make async stuff with your line
and call next() when your are done.

var ReadLines = require('read-lines');
var file = new ReadLines('/path/to/my/file');

file.on('open', function() {
  //call read for start reading the first line
  file.read(); 
});

file.on('line', function(line, next) {
  console.log(line);
  //You call next to get the next line
  next();
});

file.on('error', function(err) {
  // handle here the errors
});
