为什么 Browserify 不能与 fs.readFileSync 一起使用？

Question

When I run my code:

var fs = require('fs');
var text = fs.readFileSync('data.txt').toString().split("\n");

function getDataJS(){
    var i = 0;
    var c = "";
    var d = "";
    var t = "";
    var r = "";
    for(i = 0;i<text.length;i++){
        if(i == 0){
            c = text[i];
            document.getElementById('con').innerHTML = c;
        } else if(i == 1){
            d = text[i]
            document.getElementById('dec').innerHTML = d;
        } else if(i == 2){
            t = text[i]
            document.getElementById('tes').innerHTML = t;
        } else if(i == 3){
            r = text[i]
            document.getElementById('rec').innerHTML = r;
        }
    }
}


module.exports = getDataJS();

(with my html) I get:

Uncaught TypeError: fs.readFileSync is not a function

Does anyone know why this is? I know that node does not work with browsers, but I'm confused why browserify isn't working.

Answer 1

From Browserify :

Browsers don't have the require method defined, but Node.js does. With Browserify you can write code that uses require in the same way that you would use it in Node.

---

Browserify let's you use require . It doesn't let you use the APIs provided by Node.js that are not provided by browsers… including those needed to read files from the computer the code is running on.
