Angular 7如何使用fs模块? [英] Angular 7 how to use fs module?

问题描述

我正在使用Angular 7.

I'm using Angular 7.

我试图在Typescript上使用fs模块打开目录. 我总是遇到此错误:找不到模块:错误:无法解析fs" 已经安装了types @ node和文件系统.

I tried to use fs module on Typescript for open a directory. I always have this error: "Module not found: Error: Can't resolve fs" types@node and file-system are installed.

我的代码:

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);
  }
}

你能帮我吗?

推荐答案

'fs'是NodeJS运行时的库，但是Angular Pipeline Bundle的最终产品是在浏览器中运行的前端SPA客户端.如果您需要从用户的本地文件系统中将文件加载到客户端，则需要使用浏览器的本机变体，例如看一下处理<input type="file">元素.

'fs' is a library for NodeJS runtime, but the end product of the Angular pipeline bundler is a frontend SPA client which runs in a browser. If you need to load a file into the client from the user's local filesystem then you need to use browser native variant e.g. take a look at handling <input type="file"> elements.
