Node currently enables class construction in Strict mode.
If I have the following class:
"use strict"
class MyClass {
constructor(foo) {
this.foo = foo
}
func(){/*ETC */}
}
What is the corresponding export statement for it to be exportable to another module. What about the import statement from another file?
The same way you would currently "import" or "export" anything else currently in node, using commonJS require and module.exports:
Foo.js
class Foo {}
module.exports = Foo
// or if you want to edit additional objects:
// module.exports.Foo = Foo
// module.exports.theNumberThree = 3
Bar.js
var Foo = require("./Foo")
var foo = new Foo()
This is really an issue with how much Node supports ES6 modules. While it currently allows for classes, the import/export features of ES6 are not implemented yet, and relies more on CommonJS require.
To export use the following:
//MyClass.js
class MyClass {
constructor(foo) {
this.foo = foo
}
func(){/*ETC */}
}
module.exports = function(foo){
return new MyObject(foo);
}
To Import:
//in app.js
var myClass = require('./MyClass');
var mc = new myClass(foo);
