Hi all,

This is just to announce my naive yet functional port of Google’s  
mod\_pagespeed to nginx.  
I’m not sure I’ll have much time to improve on this, but this might  
interest  
you.

Right now it compiles with the latest stable version of mod\_pagespeed  
and  
does a very simple parsing using the AttrValuesSaverFilter that I found  
in  
the unittests. (it just saves all the html tag attributes found while  
parsing in a string).

The code and instructions to compile it can be found here :

Happy hacking,  
Matthieu.

Out of curiosity, have you defined a mechanism to configure nginx to use  
any  
of the predefined filters? It looks like you were aware of  
RewriteOptions,  
which is the API-based equivalent to pagespeed.conf, but you are not  
using  
it yet in

> <https://github.com/mtourne/ngx_instaweb/blob/master/ngx_http_instaweb_module.cpp>

.

The next step in your nginx integration looks to be resource-handling  
and  
fetching. Specifically, you need to define a way to fetch external HTTP  
resources referenced on a page, and a way to handle fetches for  
rewritten  
resources. We can help you if you have any questions feel free to reach  
out.

We’ve been working along the same lines you have: starting with a  
mod\_pagespeed build, generate a linkable library that has the kernel of  
functionality needed to integrate mod\_pagespeed’s parser & algorithms  
into a  
new platform.

Cool. As you get time to push this forward, please don’t hesitate to  
ask  
questions.

Thanks! It was a goal up front to make ports like this possible.

This Makefile could definitely help. I was also wondering if there was a

I’m not 100% sure – we are not experts in the .gyp file system  
ourselves  
although there is doc here:  
[http://code.google.com/p/gyp/wiki/InputFormatReference](http://code.google.com/p/gyp/wiki/InputFormatReference). What problem  
are  
you trying to solve?

I think I started looking at creating a RewriteOptions object, but got  
side  
tracked and this project has been idle for a little while.  
I just updated it this weekend for the latest mod\_pagespeed, and put it  
out  
there.

I like how the instaweb API is designed, and how you provide “backend

With nginx extensive subrequests mechanism, fetching external resources  
shouldn’t be too difficult.

Thank you!

Matthieu.
