Enumerate system drives in nodejs - node.js

Question

Is there a way to retrieve the drive name of all logical drives on a computer ?
I've looked at the fs api, but from there I can only enumerate the files and directories of a given directory.

Answer 1

I'm not sure what you mean by "drive name". If you mean drives in the form of \\.\PhysicalDriveN, I faced the same problem and implemented this module that works in all major operating systems:
https://github.com/resin-io/drivelist
For Windows, you get information such as:
[
{
device: '\\\\.\\PHYSICALDRIVE0',
description: 'WDC WD10JPVX-75JC3T0',
size: '1000 GB'
},
{
device: '\\\\.\\PHYSICALDRIVE1',
description: 'Generic STORAGE DEVICE USB Device',
size: '15 GB'
}
]

If you targeting on Windows, you could try this:
This solution base upon the idea from this post.
I wrap it with promise.
var spawn = require("child_process").spawn
function listDrives(){
const list = spawn('cmd');
return new Promise((resolve, reject) => {
list.stdout.on('data', function (data) {
// console.log('stdout: ' + String(data));
const output = String(data)
const out = output.split("\r\n").map(e=>e.trim()).filter(e=>e!="")
if (out[0]==="Name"){
resolve(out.slice(1))
}
// console.log("stdoutput:", out)
});
list.stderr.on('data', function (data) {
// console.log('stderr: ' + data);
});
list.on('exit', function (code) {
console.log('child process exited with code ' + code);
if (code !== 0){
reject(code)
}
});
list.stdin.write('wmic logicaldisk get name\n');
list.stdin.end();
})
}
listDrives().then((data) => console.log(data))
Test it, you will see the result like:
["c:", "d:"]

Based on Edwin Lees answer:
const child = require('child_process');
child.exec('wmic logicaldisk get name', (error, stdout) => {
console.log(
stdout.split('\r\r\n')
.filter(value => /[A-Za-z]:/.test(value))
.map(value => value.trim())
);
});
Output: ['C:', 'D:'] etc.

How about using the DiskPart command? Does running diskpart list in the command line give you the output you need? If so you can execute this in node using child_process.exec
var exec = require('child_process').exec
var cmd = 'diskpart list'
exec(cmd, function(err, stdout, stderr) {
if (err) {
console.log('error running diskpart list command')
console.log(err)
return
}
console.log('stdout data')
console.log(stdout)
console.log('stderr data')
console.log(stderr)
})

+1 for #Bagherani's downgrade suggestion!
I am using Electron React Boilerplate v4.0 and could not get drivelist to load. I downgraded to drivelist#5.2.12 and it works for my needs.
