How to properly export an ES6 class in Node 4?
If you are using ES6 in Node 4, you cannot use ES6 module syntax without a transpiler, but CommonJS modules (Node's standard modules) work the same.
module.export.AspectType
should be
module.exports.AspectType
hence the error message "Cannot set property 'AspectType' of undefined" because module.export === undefined
.
Also, for
var AspectType = class AspectType {
// ...
};
can you just write
class AspectType {
// ...
}
and get essentially the same behavior.
// person.js
'use strict';
module.exports = class Person {
constructor(firstName, lastName) {
this.firstName = firstName;
this.lastName = lastName;
}
display() {
console.log(this.firstName + " " + this.lastName);
}
}
// index.js
'use strict';
var Person = require('./person.js');
var someone = new Person("First name", "Last name");
someone.display();
