webpack - Angular 4: "Cannot find name 'require'

Question

I am building an app with Angular 4 and webpack.

I have the following in one of my components:

ngOnInit() {
    require('/assets/js/regular-expresions.js');
}

When I attempt to compile, I get:

ERROR in C:/SRC/Sandbox/eat-sleep-code.com/src/app/content.component.ts (21,9): Cannot find name 'require'.

I have ran npm install @types/node --save-dev and updated my tsconfig.json to look like:

{
  "compileOnSave": false,
  "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "baseUrl": "src",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "types": [
      "node"
    ],
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2016",
      "dom"
    ]
  }
}

But alas, the same error keeps getting thrown. Any ideas?

Try adding declare var require: any; on top.
