fs.existsSync is not a function in Angular (5)

I'm trying to run an Angular 5 app through Visual Studio Code - the code compiles without errors, but I'm receiving a "fs.existsSync is not a function" error when viewing it on localhost:4200. The full error message is

module.exports< devmode.js:33 <anonymous> devmode.js:31 <anonymous> devmode.js:1 ./node_modules/selenium-webdriver/lib/devmode.js http://localhost:4200/vendor.bundle.js:1084:1

Other questions relating to this error mention Electron, but I'm not using that package.

I'm new to all of this and so don't know what other information I should be providing. If it helps, my npm version is 5.6.0, node is version 6.11.0 and the contents of my package.json are:

"dependencies": {
    "@angular/animations": "^5.2.0",
    "@angular/common": "^5.2.0",

  },
  "devDependencies": {

    "ts-node": "~4.1.0",
    "tslint": "~5.9.1",
    "typescript": "~2.5.3"
  }

What do I need to be looking for in my code to fix this error?

Thanks

Well, it appears to have been a rogue auto-import from your editor. It was importing HttpClient from WebDriver and not Angular. Use this:

import { HttpClient } from '@angular/common/http';
