Javascript `require` instead of html `script` at three.js file in node.js

I use javascript require instead of html script at three.js file in node.js. a section of html file:

<script src="js/controls/DragControls.js"></script>
<script src="js/controls/OrbitControls.js"></script>
<script src="js/controls/TransformControls.js"></script>

<script src="js/libs/stats.min.js"></script>
<script src="js/libs/dat.gui.min.js"></script>

an equivalent section of javascript file:
> var THREE = require(’…/build/three.js’)

        //module.exports = THREE
        THREE.DragControls = require('./js/controls/DragControls.js')
        THREE.OrbitControls = require('./js/controls/OrbitControls.js')
        THREE.TransformControls = require('./js/controls/TransformControls.js')
        var Stats = require('./js/libs/stats.min.js')
        var dat = require('./js/libs/dat.gui.min.js')

so the browserify command show blank page in the browser.I think maybe the codes in javascript js file are not correct.so what should I do?

source is:

Did you try removing the .js I think it is implied?

No, a require statement uses the actual filename.

I would say that this problem originates in the fact of the import order… Possibly misspelled routings. But I couldn’t know without an error or maybe an assessment of the total code.
