Using absolute path in Angular 2 + Electron

I started messing around with Angular 2 and Electron, and used this starter package. Everything seems to be going well, I'm even able to use the node fs package to read from a directory.

The problem I'm having is that I can't seem to be able to use an absolute path for the readdirSync() method. It only takes a relative path.

I did find this in the docs for fs that you can use the URL package to show an absolute path for readdirSync(), like so:

const fs = require('fs');
const { URL } = require('url');

// file:///C:/tmp/hello => C:\tmp\hello
fs.readFileSync(new URL('file:///C:/tmp/hello'));

That looks great, but in my Angular 2/TypeScript/Electron world that doesn't seem to work. Mine looks like this:

import { Injectable } from "@angular/core";
import {readdirSync} from "fs";
import { URL } from "url";


@Injectable()
export class LinkDocRetrieverService {
    getFiles():Array<String> {

        // read through all the directories to get all the files and folder names

        let u = new URL("file:///C:/SAFE/MISC");
        let x = readdirSync(u);
        console.log("files retrieved="+ x.length);

        let files: Array<string> = [];
        x.forEach(f => {
            files.push(f);
        });
        return files;
    }
}

Both intellisense and runtime both tell me that

[ts] Argument of type 'URL' is not assignable to parameter of type 'string | Buffer'. Type 'URL' is not assignable to type 'Buffer'. Property 'write' is missing in type 'URL'.

I would have expected the syntax to be the same, but no luck.

I have read a lot of posts stating that they can't run the fs package in Angular 2 + Typescript, but it works well for me, as long as I use a relative path. I just need help getting the absolute path to work. Thanks in advance.

Documentation states that URL support was introduced in v7.6.0 and is experimental. Electron uses v7.4.0, thus you can not use URL with fs yet.

fs.readFileSync('C:/tmp/hello')

Should work just fine.
