Won't start: Use of const in strict mode.

[edwardmsmith]

I'm new to the whole es6/babel thing, but interested in trying this out.

I've cloned the repo and when I try to start it with either npm start or npm run dev, I get the following error:

const PORT = process.env.PORT || 3000;
^^^^^
SyntaxError: Use of const in strict mode.

Obviously it goes away if I remove the use strict or change const to var, but have to assume I'm doing something wrong elsewhere.

I'm using node v0.12.7 (through nvm). Are you actually running this on IO.js?

Thanks!

Hi!

I wrote the tutorial using IO.js, which I probably should have mentioned. Node still requires that you pass --harmony to enable base ES6 const/let etc. support. You can also turn on other features with other flags, but only index.js is untouched by Babel here, so you shouldn't need to.

I just pushed a new package.json which should fix this (seems to work locally in 0.12.6). Let me know :)

Thank you!

I considered adding the --harmony flag, but did not know if that would interfere with the babel stuff.

Ah, no problem. I don't think it should interfere with the babel, fingers crossed!
