Version 4.0.*
import Sudoer from 'electron-sudo';
let options = {name: 'electron sudo application'},
sudoer = new Sudoer(options);
/* Spawn subprocess behavior */
let cp = await sudoer.spawn(
'echo', ['$PARAM'], {env: {PARAM: 'VALUE'}}
);
cp.on('close', () => {
/*
cp.output.stdout (Buffer)
cp.output.stderr (Buffer)
*/
});
/* Exec subprocess behavior */
let result = await sudoer.exec(
'echo $PARAM', {env: {PARAM: 'VALUE'}}
);
/* result is Buffer with mixed (both stdout and stderr) output */
/* Usage with Vanila JS */
var Sudoer = require('electron-sudo').default;
var sudoer = new Sudoer(options);
sudoer.spawn('echo', ['$PARAM'], {env: {PARAM: 'VALUE'}}).then(function (cp) {
/*
cp.output.stdout (Buffer)
cp.output.stderr (Buffer)
*/
});

var sudo = require('electron-sudo');
var options = {

options: {
// Can use custom environment variables for your privileged subprocess
env: {'VAR': 'VALUE'}
// ... and all other subprocess options described here
// https://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback
},

ps.stdout.on('data', function(data) {});
setTimeout(function() {
ps.kill()
}.bind(ps), 50000);
}
}
};
sudo.exec('echo hello', options, function(error) {});
Tests
npm i && npm test
Usage with Webpack
Webpack config should contain __dirname
equals true
for work properly
let nodeModules = fs.readdirSync('./node_modules')
.filter((module) => {
return module !== '.bin';
})
.reduce((prev, module) => {
return Object.assign(prev, {[module]: 'commonjs ' + module});
}, {});
export default {
...
target: 'electron',
node: {
/* http://webpack.github.io/docs/configuration.html#node */
__dirname: true
},
externals: nodeModules
};
