How can the file system module (fs) be utilized in Angular 7?

Hello, I am currently working with Angular 7.

I recently attempted to utilize the fs module in Typescript to open a directory. However, I encountered an error message stating: "Module not found: Error: Can't resolve fs". Despite having types@node and file-system installed, the issue persisted.

Below is a snippet of my code:

import {Component, OnInit} from '@angular/core';
import * as fs from 'file-system';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit  {
  title = 'my-app';

  constructor() {

  }

  ngOnInit() {
    console.log(fs);
  }
}

If you have any insight or solutions, please feel free to share them with me.

Answer №1

The 'fs' module is designed for use with NodeJS, while the Angular pipeline bundler produces a frontend SPA client that operates within a web browser environment. If you want to upload a file from the user's local system to the client side, you will need to utilize a browser-native approach such as utilizing 

<input type="file">
elements.

Answer №2

fs module is not directly accessible in Angular framework. To utilize the fs module, you can install the following package:

npm install file-system --save

Usage Example:

var fs = require('file-system');
 
fs.mkdir('1/2/3/4/5', [mode], function(err) {});
fs.mkdirSync('1/2/3/4/5', [mode]);
fs.writeFile('path/test.txt', 'aaa', function(err) {})

Answer №3

The ‘fs’ module, exclusive to Node.js, is not compatible with Angular (or any other framework). When Angular code is compiled and condensed, it operates within the browser's environment, which does not provide access to the filesystem like Node.js does. Browsers are designed to be secure sandboxes that prevent unauthorized file system access by websites, ultimately safeguarding user data and privacy.
