Asynchronous Template Engine

[Malte Ubl]

Hey,

just wanted to let you know about a little extention I build upon the
regular ERB-style templating that is available through underscore.js
and other libraries.

The template engine can execute parts asynchronously. The usefulness
of this might be kind of limited but it does help with flushing
content to the browser as early as possible. It basically means that
you can execute the view at the same time as the model.

That's really cool! I was wondering how this could be done for a while
and your solution to it is very nice.

I really think async templating should become standard in the node
world.

This looks really promising :)

I implemented
- nested asynchronous partials
- optional hot code reloading
- multi line <%%> statements

Currently partials are not streamed before completion of the partial.
I might change this.

Next up is a release on github.

I'm working on a framework for async templating engines. I'm going to experiment with the ideas in Temple <http://judofyr.net/posts/temple.html>. I've had feature requests in my haml port for partials. This can't be done in a synchronous way since file IO is async.

I'll probably have something posted on Github in the next day or too. For now the project will called Grain. <http://bit.ly/7rL7h1>

What do you mean with hot code reloading?

if the template changes on the server it is recompiled and loaded into memory.

Very nice! Can't wait to play with this soon! Hopefully Ryan will like
my hot-code reloading stuff for modules as well, but gotta figure out
this libeio issue first!

I release the code with some examples and docs to GitHub

Awesome stuff, do you mind if I steal some ideas for my Grain framework?

Fork away!
