javascript - how to write file with node webkit js? -

when build app, 'fs' module doesn't work. so, must write file, when start app nothing happens. if start app with:

$ /path/to/app nw

it works correctly. what's wrong?

some code, use fs:

function check_prob_2(){     console.log('problem 2');     fs.appendfile('log.txt', 'checking problem 2: \n\n');     ...     }

i use function, doesn't work. doesn't work after build application. build this guide

try this:

include following (standard) module:

var path = require('path');

specify path follows:

fs.appendfile(path.resolve(__dirname, './log.txt'), 'checking problem 2: \n\n');

more info on __dirname global can found here.

edit

since __dirname not defined in node-webkit, you'll have use following workaround:

make file util.js or want call it, containing line:

exports.dirname = __dirname;

the __dirname variable can exposed in main file:

var dirname = require('./util.js').dirname;

and replace __dirname dirname in code.
