TypeError:fs.​​readFileSync不是函数 [英] TypeError: fs.readFileSync is not a function

问题描述

我的项目需要在ReactJS中使用文件系统模块.该项目是通过 create-react-app 创建的.在组件js文件之一中，我需要从目录中加载文本文件中的行.

My project require to use filesystem module in ReactJS. The project was created with create-react-app. In one of the component js file, I need to load lines in a textfile from a directory.

var fs = require('fs');var readline = require('readline');var stream = fs.readFileSync(C:/data/localmap.txt).toString().split(" \ n);.......

终端没有错误，但是浏览器显示错误，如下所示:

There isn't error in the terminal, but the browser shows error as shown below:

TypeError:fs.​​readFileSync不是函数

与此处提出的问题不同，我使用了require语句作为注释建议.我一直在网上寻找资源，但似乎这不是一个普遍面临的问题.

Different from the issue raised here, I have used require statement as the comments suggested. I have been looking around online for resources but seems like it is not a widely faced problem.

推荐答案

fs 是Node.js模块.您不能直接在浏览器中运行Node.js.

fs is a Node.js module. You cannot run Node.js directly in the browser.

除非您在启用了Node集成的情况下运行自己的Chromium实例(例如Electron)，否则将无法使用Node.js模块.

Unless you are running your own Chromium instance with Node integration enabled, (such as Electron) you will not be able to use Node.js modules.
