如何创建一个JavaScript对象以通过export.module导出？

Question

I have an javascript test class

var Test = function() {
    var _object = {} ;
    _object.url = null ;
    return _object ;
}
exports.module = Test ;

Which I can then import via

var Test = require('./test') ;

When I do this however I get an error.

var test = new Test() ;
TypeError: Test is not a constructor

I'm expecting to have a test instance of Test such that test.url will return null. How would I change the source so that var test = new Test() works without throwing an error?

Answer 1

You'll want to use module.exports instead of exports.module

The way you have it written currently, you'd be able to reference your Test object like so

var Test = require('./test');
var test = new Test.module();

Answer 2

You are doing
exports.module = Test;
So what gets exported from test is module hence, you will have to

var test = require('./test'); var Test = new test.module();


If you directly want to use your Test class then you can module.exports = Test in your test.js file

and then you can directly do
var Test = require('./test'); var test = new Test();
where you are importing it.
