Export a class in Node module.exports = {}

Question

I want to export a class with static methods in a module, along with other functions. I'm trying to do

module.exports = { fun: function(){}, class: MyClass } class MyClass { static get prop() { return 'property'; } }

But it does not work. Is there a way to export class as part of module.exports object?

I'm using not class but say abc and it's not working -- the error is that abc is not defined when I try to require it from other file. I can do module.exports.abc = MyClass, but that would not allow me to use just MyClass inside the module — Anton

I see myClass and not MyClass in your exports definition — Backslash36

Why don't you use ES6 module exports? export class MyClass {} export function fun() {} — Bergi

@Bergi: ES6 module imports can only be on the top of the file. Sometimes it's necessary to conditional import a module. This is not possible then. — andreas

@andreas It will be possible with import() statements, and until then you can still just require the transpiled module — Bergi

Class definitions aren't hoisted, which means that your class won't be in scope when you declare those exports. Move them down to below the definition.

class MyClass { static get prop() { return 'property'; } } module.exports = { fun: function(){}, class: myClass }

You'll also need to fix the case on the variable you export.

module.exports = { fun: function(){}, class: MyClass }

Depending on your Javascript environment, there may be compile time errors if you try and used the reserved word class as a literal object property. You can wrap it in a string to avoid this.

module.exports = { fun: function(){}, "class": MyClass }

great, the problem was with hoisting, otherwise it was just an example code for stackoverflow. thank you sir
