Re: [nodejs] porting a library to node.js

Something like facebook/regenerator would run that on stable 0.10 quite happily.

Hi!

 

You again ;-) ;-) (after Scala, Clojure.. )

 

1) No goroutinges, but streams and events (stream2 is the "new" implementation, two years age). But maybe _javascript_ generators? I'm not sure.

 

2) No yield, until new ecmascript 6, but some links

http://stackoverflow.com/questions/4126634/does-node-js-support-yield

http://blog.alexmaccaw.com/how-yield-will-transform-node

(v 0.11 not the stable 0.10.x)

 

3) setImmediate(myfn); or setTimeout(myfn, 0) (later is preferred, if your library should run in browsers too; not all the browsers implements setImmediate)

 

4) It's really simple. A complex number arithmetic library

http://github.com/ajlopez/Complexo

The key part is the package.json file where you define the entry point, the dependencies, the scripts to run (what is "npm test"?), the dev dependencies. You can get an account on NPM, and publish your module

 

Sometimes, your main module.js is splitted, like in

https://github.com/ajlopez/RustScript/tree/master/lib

but you can still tests the files 

https://github.com/ajlopez/RustScript/tree/master/test

 

notice the use of .npmignore to not publish samples files

 

Sometimes, your separated files should be arranged in one, to support browsers

https://github.com/ajlopez/Plangre

https://github.com/ajlopez/PLangRe/tree/master/lib

 

It could be rearrange with automation commands in only one to be used in browser. In the above project, I did the work with a windows command, and using the trick of defining each submodule in a function

 

mysubmodule = (function() { 

...

   return ....

}

 

if (typeof module != 'undefined' && module.exports)

    module.exports = mysubmodule;

 

and concatenating all the files in order

 

But you can use browserfy by @substack 

 

Sure, there are more complete and better samples

 

You can read a lot of good code and module use/patterns at

https://github.com/substack

ie https://github.com/substack/minimist

Hi everyone,
I'd like to port a Dart library to node.js (https://github.com/mtomassoli/golib) but I don't know much about node.js.
I have some questions:

1. Do you already have goroutines and channels in node.js?
2. Can I use yield?
3. How can I add a function to the event loop? (I'll need to emulate Dart's completers)
4. What's the structure of a node.js library/module? Any links?

Thanks.
