[英]Common module in node.js and browser javascript
I am developing a node.js app, and I want to use a module I am creating for the node.js server also on the client side.我正在开发一个 node.js 应用程序,我想在客户端使用我为 node.js 服务器创建的模块。
An example module would be circle.js:一个示例模块是 circle.js:
var PI = Math.PI;
exports.area = function (r) {
return PI * r * r;
};
exports.circumference = function (r) {
return 2 * PI * r;
};
and you do a simple你做一个简单的
var circle = require('./circle')
to use it in node.在节点中使用它。
How could I use that same file in the web directory for my client side javascript?我怎么能在我的客户端 javascript 的 web 目录中使用相同的文件?
This seems to be how to make a module something you can use on the client side.这似乎是如何制作一个可以在客户端使用的模块。

mymodule.js:我的模块.js:
(function(exports){
// your code goes here
exports.test = function(){
return 'hello world'
};
})(typeof exports === 'undefined'? this['mymodule']={}: exports);
And then to use the module on the client:然后在客户端使用模块:
<script src="mymodule.js"></script>
<script>
alert(mymodule.test());
</script>
This code would work in node:此代码将在节点中工作:
var mymodule = require('./mymodule');
It magically lets you do that.它神奇地让你做到这一点。
