Question

nodejs read file and split with \u001

I have a hadoop file that has \u001 as a delimiter, and I try to read the data and split records by \u001. But the length is always 1, that is the data is not been spilt.

var fs = require('fs');
var buffer = fs.readFile('20140820075209.txt', function (err, data) { 
  console.log(data.toString());
  console.log(data.toString().split('\\u001').length);
});

node.js

Answer 1

You shouldn't escape the backslash if you want the actual character:

console.log(data.toString().split('\u0001').length);

or:

console.log(data.toString().split('\x01').length);
