list partitions in nodejs

Question

I would like to get the list of partitions in windows, using nodejs. fs.readdir works fine for any folder below or including C:, but I cant figure out what to give it to hav

Answer 1

My 2 cents:

Slightly enhanced - a function with callback for easy integration, returns an array of drives :

/**
 * Get windows drives
 * */
function get_win_drives(success_cb,error_cb){
    var stdout = '';
    var spawn = require('child_process').spawn,
            list  = spawn('cmd');

    list.stdout.on('data', function (data) {
        stdout += data;
    });

    list.stderr.on('data', function (data) {
        console.log('stderr: ' + data);
    });

    list.on('exit', function (code) {
        if (code == 0) {
            console.log(stdout);
            var data = stdout.split('\r\n');
            data = data.splice(4,data.length - 7);
            data = data.map(Function.prototype.call, String.prototype.trim);
            success_cb(data);
        } else {
            console.log('child process exited with code ' + code);
            error_cb();
        }
    });
    list.stdin.write('wmic logicaldisk get caption\n');
    list.stdin.end();
}
