Reading a file into an array of lines in a system-independent manner

Question

In Node.js, when I want to read the lines of a file into an array, I do:

fs.readFileSync(filename).split('\r\n')

but this doesn't work on Linux. On Linux, I can do:

fs.readFileSync(filename).split('\n')

but this doesn't work on Windows. I can also do:

fs.readFileSync(filename).split(/[\r\n]+/)

which works on both systems, but hard to read.

Is there a simple, system-independent way to read a file into an array of lines in Node.js?

Answer 1

You can use constant for such needs:

var nl = require('os').EOL;

So it would look like:

var nl = require('os').EOL;
fs.readFileSync(filename).split(nl);

Or you could use just RegExp:

fs.readFileSync(filename).split(/\r?\n/)
