List sections in nodejs

Question

I would like to get a list of partitions on Windows using nodejs. fs.readdir works fine for any folder below or, including C :, but I can't figure out what to give it a list of partitions like "C:", "D:", etc.

Does anyone know what I should use?

Answer 1

Node.js does not have an api for enumerating sections. One way is to use the child_process command and execute the wmic command (or any command that can list partitions).

 var spawn = require('child_process').spawn, list = spawn('cmd'); list.stdout.on('data', function (data) { console.log('stdout: ' + data); }); list.stderr.on('data', function (data) { console.log('stderr: ' + data); }); list.on('exit', function (code) { console.log('child process exited with code ' + code); }); list.stdin.write('wmic logicaldisk get name\n'); list.stdin.end(); 

Answer 2

My 2 cents:

A bit advanced - a callback function for easy integration, returns an array of disks:

 /** * 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(); }

Not sure if it matches exactly what you are looking for, but we create a NodeJS module called drivelist that returns an array of mapped drives with their corresponding mount points (for example: installation letters on Windows):

 [ { device: '\\\\.\\PHYSICALDRIVE0', description: 'WDC WD10JPVX-75JC3T0', size: '1000 GB' mountpoint: 'C:', system: true }, { device: '\\\\.\\PHYSICALDRIVE1', description: 'Generic STORAGE DEVICE USB Device', size: '15 GB' mountpoint: 'D:', system: false } ] 

Non-removable drives are marked as system: false , you can filter this property if this is what you are looking for.

The main advantage of this module is that it works on all major operating systems.

slightly simpler implementation:

 const exec = require('child_process').exec; exec('wmic logicaldisk get name', (error, stdout, stderr) => { if (error) { console.error(`exec error: ${error}`); return; } console.log('stdout ', stdout); console.log('stderr ', stderr); });
