OpenResty - General-purpose web service platform for web applications


This document describes OpenResty 0.5.2 released on November 27, 2008.


This module implements the server-side OpenResty web service protocol. It provides scriptable and extensible web services for both server-side and client-side (pure AJAX) web applications.

Currently this module can serve as a public web interface to a distributed or desktop PostgreSQL database system. In particular, it provides roles, models, views, actions, captchas, the minisql language, and many more to the web users.

"Another framework?" No, no, no, not all!

OpenResty is not a web application framework like Jifty or Catalyst. Rather, it is

  • A REST wrapper for relational databases

  • A web runtime for 100% JavaScript web sites and other RIAs.

  • A "meta web site" supporting other sites via web services.

  • A handy personal or company database which can be accessed from anywhere on the web.

  • A (sort of) competitor for the Facebook Data Store API.

We're already running an instance of the OpenResty server on our Yahoo! China's production machines:

And there're several (pure-client-side) web sites alreadying taking advantage of the services:

OpenResty's admin site

agentzh's blog and EEEE Works' blog

Yisou BBS

See OpenResty::Spec::Overview for more detailed information.

OpenResty::CheatSheet also provides a good enough summary for the REST interface.

You'll find my slides for the D2 conference interesting as well:

or the original XUL version: (Firefox required)

Another good introduction to OpenResty's REST API is summerized in the slides for my Y!ES talk and my Beijing Perl Workshop 2008 talk:

and a more pretty (XUL) version can be got from here: (Firefox required)

There're also a few interesting discussions about OpenResty on my blog site:

"OpenResty versus Google App Engine"

"Google's crawlers captured OpenResty's API!"

"Video for my D2 talk about OpenResty and its nifty apps"

"The first feature that is powered by OpenResty"

"Client-side web site DIY" (Chinese)

"OpenResty 平台相关资料" (Chinese)


This library is still in the beta phase and the API is still in flux. We're just following the "release early, releaes often" guideline. So please check back often ;)
