本文链接地址: cowboy-高性能简洁的erlang版web框架

大部分的分布式系统只要有业务价值,必须提供如API,监控,管理界面等等,而http是目前事实上的标准,换句话说分布式系统必须提供强大的web框架,编写业务才能容易上手。 Erlang系统第一天就是设计干这个的,自然有很多web框架,出名的如mochiweb, cowboy,chicagoboss, misultin,inets等框架,竞争也是非常激烈。今天我要推荐的是新秀:cowboy,项目在这里


Cowboy is a small, fast and modular HTTP server written in Erlang.


Cowboy aims to provide a complete HTTP stack in a small code base. It is optimized for low latency and low memory usage, in part because it uses binary strings.

Cowboy provides routing capabilities, selectively dispatching requests to handlers written in Erlang.

Because it uses Ranch for managing connections, Cowboy can easily be embedded in any other application.

No parameterized module. No process dictionary. Clean Erlang code.

目前还支持websocket和spdy协议(由leofs赞助),是个完整的http协议栈实现,功能强劲。由于是最近才发展起来的,充分考虑了性能,强调代码的整洁,作者在产品层面对erlang的优缺点非常了解,实现的很优雅很高效。 目前多个项目都是用它支撑的,也反过来刺激它走的很稳很快,代码维护也很活跃,比如竞争对手misultin感觉没有超越的希望就放弃了。

Misultin development has been discontinued.

There currently are three main webserver libraries which basically do similar things:
* Mochiweb
* Cowboy
* Misultin
Mochiweb has been around the block for a while and it’s proven solid in production, I can only recommend it for all basic webserver needs you might have. Cowboy has a very interesting approach since it allows to use multiple TCP and UDP protocols on top of a common acceptor pool. It is a very modern approach, is very actively maintained and many projects are starting to be built around it.
