使用node.js时如何在客户端和服务器端导入javascript代码？

Question

I have a couple of Javascript functions I need to use both on the server side and on the client side in a node application.

On the server side, I could create a module and require it. I would need to module.exports my functions. Unfortunately, I could not use that code module on the client side, because there is no such thing as require on the client side.

I don't want to maintain the (nearly) same code in two version of the files. Is there a standard/safe way to import Javascript code in a node module? I mean literally, without using require and module.exports ? Or is there another solution to my issue?

Answer 1

您正在寻找browserify ，它允许您在浏览器中使用require()和module.exports运行Node- module.exports模块。

Answer 2

I have used browserify in the past. It allows you to use common.js style require syntax on the client side. A word of warning, you will probably have to use a single client side entry point, and therefore re-write a lot of your client side code.

Here's the link - borwserify

Answer 3

I'm sure I've seen Ember implement its own require method but I can't find any documentation for it.

On the way I saw http://www.requirejs.org which creates its own new require method which works which both the browser and nodejs.
