Does node.js support yield?

Question

Is there any way to get generators into node.js?

I\'m currently faking them with callbacks, but I have to remember to check the response of the callback inside of my gen

Answer 1

We are using gnode for generators in node < 0.11.3 - https://github.com/TooTallNate/gnode

Answer 2

The issue proposing generatiors in v8 has recently been accepted by v8 project member.
Please vote there to make yield come true.

Answer 3

Yes, since version 0.11. Enjoy!

Answer 4

You can use generators in Node.js, but only in 0.11+. Node.js 0.12 (stable) is now available. Add --harmony_generators or --harmony to the command line parameters of node to enable it.

With Traceur, you can compile advanced JavaScript to vanilla JavaScript. You could make a loader for node.js that does this on-the-fly. Since it runs on, and compiles to vanilla JavaScript, it runs in node.js < 0.11 as well as in the browser.

Facebook has developed a lighter version that only supports generators, called Regenerator. It works similarly to Traceur.
