There are quite a few projects using Lua for web development.

For example, <a href="http://alt.textdrive.com/nanoki/" rel="nofollow noreferrer">Nanoki</a>, an HTTP and wiki engine developed in pure Lua.

Or Sputnik, which is build on top of Kepler.

That said, Lua is very much a, hmmm, "do it yourself" kind of environment.

I am using Lua right now to build a web application! Whatever happened to software developers that "do it yourself" got a bad name - too lazy, weaned on bloated megabytes of support libraries, or what? In reality, as others have pointed out, there is decent support, just not on the scale of Python, say. Lua is by far the fastest scripting language (especially with www.luajit.org around), and much, much cleaner as a language design than any other in its league out there. This is vital for long-term maintenance.

For those using <a href="http://lighttpd.net" rel="nofollow noreferrer">lighttpd</a> as their webserver (me included), the added bonus is that the full power of Lua is available for <a href="http://redmine.lighttpd.net/wiki/1/Docs:ModMagnet" rel="nofollow noreferrer">mod_magnet</a> scripts, useful for synchronous request handling/rewriting-on-steroids.

blocks|key|2832923|text|正如其他人提到的，Lua是一种“自己动手”的环境。而且，与Perl/PHP/Python/Ruby相比，它速度非常快，内存效率也很高，特别是在使用LuaJIT的情况下。与C/C%2B%2B代码的集成非常容易。通常，对于典型的web应用程序来说，这些点与数据库无关，后者的性能通常受到数据库的限制。此外，您并不真正关心C/C%2B%2B集成，也不想自己动手，而是希望在现有框架的基础上进行构建。因此，我不认为Lua适合典型的web应用程序。同时，也有一些利基应用程序，卢亚闪耀。例如，我们公司致力于构建用于服务的高性能HTTP服务器。因此，我们正在使用的是我们自己的HTTP服务器，它是在C%2B%2B中从头编写的，它将Lua集成为业务逻辑的脚本语言。这使得我们能够快速地定制Lua中的业务逻辑，而如果它是纯C%2B%2B的话，我们就必须这样做。同时，我们始终可以选择在C%2B%2B中执行性能关键部分。如果我们使用任何其他脚本语言，我们肯定它会慢一些，它将使用更多的内存，并且通常更难与C%2B%2B代码集成。同时，如果我们使用其他脚本语言，那么我们并不太关心大量的库支持的损失，因为我们正在工作的领域是相当专门的，所以通常这些库与它无关。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2832924|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

As others mentioned Lua is "do it yourself" kind of environment. Also it is very fast and quite memory efficient compared to Perl/PHP/Python/Ruby especially if you are using LuaJIT. And it is very easy to integrate with C/C++ code. Usually these points are irrelevant for a typical web application where performance is usually restricted by database. Also where you don't really care about C/C++ integration and where you don't really want to do things yourself but rather you want to build on top of existing frameworks. For this reason I don't think Lua is a good fit for a typical web applications. At the same time there are some niche applications where Lua shines. For example our company specializes at building high performance HTTP servers used for adserving. So what we are using is our own HTTP server written from scratch in C++ which integrates Lua as a scripting language for our business logic. This allows us to do customization of the business logic in Lua quickly compared to what we had to do if it was pure C++. At the same time we always have an option to do performance critical parts in C++. If we were using any other scripting language we are positive it would be slower, it would use more memory and generally would be harder to integrate with C++ code. At the same time we don't really care much about loss of extensive library support were we using other scripting languages as the domain we are working in is quite specialized so usually those libraries are irrelevant for it anyway.

Cons: sometimes you have to write your own libraries for things you would get for free in Python.

blocks|key|1309886|text|我用Lua编程了几个网站。第一个是我的魔兽世界行会的raid规划师(这通常是你在Lua.中开始编程的方式)。为此，我使用了mod_lua和一个阿尔法版本的Apache2.4。另外两个是为客户而设的小型竞赛场地，由WSAPI、Nginx、产卵-fcgi和轨道开发。这个设置非常快，比mod_lua和我看到的任何其他东西都快。页面会立即显示，就好像它们在缓存中一样！这是非常愉快的经验和卢阿使你快速的生产力。但你最好有条理。Lua在网络开发方面缺少了很多电池，所以你经常需要实现你自己的电池，它可能会变得很混乱。所以我建议你在开始之前先计划好你需要什么。我在MySQL中使用了自己的Lua+"ORM“，并为模板使用了Lua页面的分叉版本。如果您想尝试一下Lua%2BWsapi%2BNginx，请看这里：http://mascarenhas.github.com/2009/10/24/wsapi-nginx-fcgi.html，我认为这是最好的设置。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1309887|entityMap|0|LINK|mutability|MUTABLE|url|http://mascarenhas.github.com/2009/10/24/wsapi-nginx-fcgi.html^0|9M|1Q|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I have programmed a few websites with Lua. The first one was a raid planner for my World of Warcraft guild (that's often how you start programming in Lua...). I used mod_lua with an alpha version of Apache 2.4 for that. Two others were small contests sites for customers, developed with WSAPI, Nginx, Spawn-fcgi and Orbit. This setup is damn fast, faster than mod_lua and anything else I have seen. The pages would display instantly as if they were in cache ! The experience was very pleasant and Lua makes you quickly productive. But you better be well organized. Lua is missing a lot of batteries when it comes to web development, so you often have to implement your own and it can become messy. So I suggest you plan what you will need before you start. I used my own Lua "ORM" with MySQL and a forked version of Lua Pages for the templates. Have a look here if you want to give Lua+Wsapi+Nginx a try : <a href="http://mascarenhas.github.com/2009/10/24/wsapi-nginx-fcgi.html" rel="noreferrer">http://mascarenhas.github.com/2009/10/24/wsapi-nginx-fcgi.html</a>
I think it is the best setup.

blocks|key|2833056|text|我们成功地使用了lua作为后端实现。您还可以查看用于嵌入式设备的JUCI+webgui。它使用lua作为后端实现。您可以查看代码如何与lua/C后端交互：https://github.com/mkschreder/juci|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2833057|但是，请注意，这个后端是一个纯jsonrpc后端，因此它不会创建任何类似php或cgi页面的html。Lua是完美的，如果您所做的只是处理和响应json请求。您还可以在php中使用主应用程序，并使用lua在后端编写应用程序。或者主要应用程序完全在javascript中。|2833058|我认为，如果要在想要生成html的地方使用lua，那么您会发现它缺乏许多特性，但是如果将它限制在纯功能后端实现上，那么您会发现它运行得非常好。|2833059|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/mkschreder/juci^0|25|Y|0|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@]|C|$]]|$1|F|3|G|5|6|7|U|8|@]|9|@]|C|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|C|$]]]|I|$J|$5|K|L|M|C|$N|O]]]]

We use lua with great success for our backend implementation. You can also have a look at JUCI webgui for embedded devices. It uses lua for backend implementation. You can have a look at how code interacts with lua/C backend: <a href="https://github.com/mkschreder/juci" rel="nofollow">https://github.com/mkschreder/juci</a>

Note however that this backend is a pure jsonrpc backend so it does not create any html like php or cgi pages. Lua is perfect if all you do is handle and respond to json requests. You can also have main application in php and use lua to write the application on the backend. Or main application completely in javascript. 

I think that if you are going to use lua in places where you want to generate html then you will find it lacking many features, but if you limit it to purely functional backend implementation then you will find that it works very well.

I come from a Java and PHP background to build web applications.

Has anyone used Lua before to build a web applications?

Question: If so, what are the pro's &amp; con's of using Lua versus PHP or Java for a web application? (e.g. web server support, performance, code maintenance, etc).

Has anyone used Lua to build a web application?
