Can't use npm packages with TS module import from Angular that uses NodeJS core module

[laurentperroteau]

Describe the bug
I can't use 3rd party libraries with TS module import from Electron's Renderer process (Angular) that uses NodeJS core module.

To Reproduce
Steps to reproduce the behavior:

1. npm install fs-extra --save
2. cd app && npm install fs-extra --save && cd ..
3. Import package in app.component.ts: import * as fsExtra from 'fs-extra'; (same problems with 3 others package that depend of 'fs')
4. Use it in app.component.ts :

fsExtra.copy('/tmp/myfile', '/tmp/mynewfile')
      .then(() => console.log('success!'))
      .catch(err => console.error(err));

5. npm start

Errors

./node_modules/graceful-fs/graceful-fs.js:1:9-22 - Error: Module not found: Error: Can't resolve 'fs' in '/home/.../angular-electron/node_modules/graceful-fs'

./node_modules/jsonfile/index.js:10:8-21 - Error: Module not found: Error: Can't resolve 'fs' in '/home/.../angular-electron/node_modules/jsonfile'

Additional context

• OS: Linux Ubuntu 20.04. LTS

Thanks in advance for the help, I know is not anymore the recomend way to use Node library in the rendered context but my app start with this template 5 years ago in this way

Hi

Please have a look at README.md

electron.service.ts

[...]
import * as fsExtra from 'fs-extra';

@Injectable({
  providedIn: 'root'
})
export class ElectronService {
  [...]
  fsExtra: typeof fsExtra;

  [...]

  constructor() {
    // Conditional imports
    if (this.isElectron) {
      [...]
      this.fsExtra = window.require('fs-extra');
    }
  }
}

app.component.ts

 if (electronService.isElectron) {
      electronService.fsExtra.copy('/tmp/myfile', '/tmp/mynewfile')
            .then(() => console.log('success!'))
            .catch(err => console.error(err));
}

This perfectly works.

Thanks, so if another person is in the same case: it is no longer possible (it was at least until v6.0.1) to import packages which depend on core Node like any browser package.
