In Angular application, I keep getting this error Cannot find module 'fs'

Question

In my service file, I import these four libraries:

import * as async from "async";
import * as officegen from "officegen";
import * as path from "path";
import * as fs from "fs";

While there's no problem with async,officegen and path. The fs line keeps giving this error:

ERROR in src/app/matieres/matiere.service.ts(11,45): error TS2307: Cannot find module 'fs'.

In hopeless attempts, I tried these:

npm install fs -g

npm install fs --save

npm install file-system -g

npm install file-system --save

None of which worked This is really confusing. Anyone can help?

`fs` is for backend node development. Why do you need it in Angular? — Heretic Monkey, Jun 11 '19 at 15:26
Have you wiped out your modules and reinstalled? `rm -r node_modules` then `npm i` — Ben Racicot, Jun 11 '19 at 17:17
@HereticMonkey I'm writing a service which contains the code of generating word documents. Then I will call that service in the app.component.ts — Ahmed Ghrib, Jun 12 '19 at 09:02

You might need to use npm install --save-dev @types/node

Might also need to check tsconfig.json for "moduleResolution": "node"

If that doesn't help, these other questions look similar:
