Does `node --harmony` works stable on all platforms?

[Alexey Petrushin]

Want to try generators `node --harmony` but worried a little about:

- if it works on all platforms?

- does the API stable and won't be changed in future?

[Ben Noordhuis]

No and no, in general. --harmony is for experimental features whose
spec hasn't finalized yet or whose implementations aren't fully baked.
Once a Harmony feature is considered stable, it's enabled by default
(c.f. Promises in node.js master.)

been playing with it on debian wheezy, coffee + koajs + node-mysql, try catch gets all the sql errors so you can do really nice transactions. looks ok at first glance I'll start converting my apps to dump callbacks. Not that I mind the callbacks but you get all the errors with the 'yield way'

Hi,

- yes in general all nodejs functionaly works on all supported platforms

- no it might, but not in near future as upcomming nodejs 0.12 and current Firefox has it already implemented

Checkout http://koajs.com/ it aims to replace Express by using generator functions and avoiding callback hell

Both are incomplete implementations.

Hi Rick,

to clarify you anwser a bit, yes you are right, generators in existing implementations are incomplete, as it is draft http://wiki.ecmascript.org/doku.php?id=harmony:generators it's even suprising that they are in any stable envirnonment(talking about Firefox).

But what in my opinion, is now importat that they are usable in node as coroutine solution to callback hell. If you have any notes on how current implementation would change in near future please let me know.

This is just a strawman, the latest specification draft is maintained online here: https://people.mozilla.org/~jorendorff/es6-draft.html

 

it's even suprising that they are in any stable envirnonment(talking about Firefox).

It's not very surprising, the spec is still in development, will be frozen Dec 2014, but won't be officially published until June 2015.

But what in my opinion, is now importat that they are usable in node as coroutine solution to callback hell.

As long as you're ok with a potentially moving target, then yes.

 

If you have any notes on how current implementation would change in near future please let me know.

Yes, I recorded the resolutions, which could not possibly be implemented yet: https://github.com/rwaldron/tc39-notes/blob/master/es6/2014-07/jul-29.md#short-discussion-about-making-generatorreturn-throw-a-special-exception

issue is not to gallop into production now even if the experimental looks surprisingly solid. But one has a pretty realistic environment to scramble up the learning curve and rewrite stuff for when .12 comes out with all seals, my hat off to all contributors for that because it is a big time saver
