Node.js Question

How can I create a directory in user home using nodejs?

I am developing a node.js application on Ubuntu and am trying to programmatically create a directory for my application in the user's home directory.

When I execute the following Javascript in Node:

const fs = require("fs");
fs.mkdirSync("~/mynewdir");


I get the following error:


Error: ENOENT: no such file or directory, mkdir '~/mynewdir'
at Error (native)
at Object.fs.mkdirSync (fs.js:923:18)
at repl:1:4
at sigintHandlersWrap (vm.js:22:35)
at sigintHandlersWrap (vm.js:73:12)
at ContextifyScript.Script.runInThisContext (vm.js:21:12)
at REPLServer.defaultEval (repl.js:346:29)
at bound (domain.js:280:14)
at REPLServer.runBound [as eval] (domain.js:293:12)
at REPLServer. (repl.js:545:10)


Executing:

fs.mkdirSync("/home/dah/mynewdir");


works just fine however, but I want to use the home directory of whomever is executing the script.

Does anyone have any suggestions?

Edit - this question is not a duplicate. In this case, the issue is not finding the home directory (I already have this), but why the fs module won't use it.

Answer Source

You can do it like that:

const homedir = require('os').homedir();
// `homedir()` returns absolute path so we use `join` here
require("fs").mkdir(require('path').join(homedir, 'mynewdir'));
