node.js / ES6 / class creation : SyntaxError: Unexpected reserved word

Question

I try to create a class on my node.js / express app.

It works in basic js / prototype mode such as :

function MyClass() { 
    /* constructor code *         


        

Answer 1

You can do this with io.js

iojs --use_strict --harmony_classes my-app.js

Or on node.js with traceur

var traceur = require('traceur');
traceur.require.makeDefault(function(file) {
  return file.indexOf('node_modules') == -1;
});

require('./my-app').run();

Make sure to test the new features before using them, some are not supported. Edit: You can check the compatibility list from here
