Can't write to file NS_ERROR_FILE_UNRECOGNIZED_PATH

Question

I try to write in file using sdk.

var fs = require('sdk/io/fs');

fs.writeFile('text.ini', '123', null, function (error) {
  callback(error);
});

But i obtain NS_ERROR_FILE_UNRECOGNIZED_PATH. Which path should I use?

Answer 1

You can obtain special directories' path with sdk/system.

const { pathFor } = require('sdk/system')
const path = require('sdk/fs/path'); // important for cross-platform compatibility 

var profile = pathFor('ProfD');
var filepath = path.join(profile, 'text.ini');

// now pass filepath to writeFile
