Hi haskellers and specially the web developers. http://hackage.haskell.org/package/MFlow-0.1.5.3 MFlow is a is a Web framework with some unique, and I mean unique, characteristics that I find exciting: - It is a Web application server that start and restart on-demand stateful web server processes (not request.-response) This means that all the page navigation can be coded in a single procedure. This increases readability of the programmer code. I woul call it a anti-node.js. Buit usual request-response (stateless) server processes are also allowed - When the process is invoqued as result of an URL request, the Web app server not only restart the process but also recover its execution state. The enclosing Workflow monad provides the thread state persistence. There are state timeouts and process timeouts defined by the programmer. Processes with no persistent state (transient) are possible. -The user interface is made of widgets. They are formlets with added formatting, attributes, validations, modifiers and callbacks, that are composable, so the pieces are reusable and return type safe responses to the calling process. Even the links are part of widgets and return back type safe inputs at compile time to the calling server process. Tho glue these components, ordinary applicative combinators and other extra combinators are used. - The widgets and the communication don´t make assumptions about the architecture, so it can be adapted to non-web environments. This versions has interface for WAI-warp, Hack, Text.XHtml (xhtml) , and Haskell Server Pages. -The widget rendering can be converted to ByteStrings automatically with special combinators. A mix of widgets with different formats can be combined in the same source file. For example Text.Html and HSP (Haskell server pages) -These widgets can be cached, to avoid widget rendering on every interaction. -To handle the back button, and because the processes are stateful, they can run backwards until the response match. This is transparent for the programmer, thanks to the embedded FlowM monad. -All the code is in pure Haskell. No deployment, special scripts, formats etc are necessary. -Besides automatic state persistence, TCache provides transactions and user data persistence, that can be configured for SQL databases. Default persistence in files permit very rapid prototyping. Just code and run it with runghc. -Has AJAX support All of this sounds very complicated, but really it is simple!. Most of these things are transparent. The resulting code is quite readable and has very little plumbing! There is a non trivial example that some of these functionalities embedded here that you can run: http://hackage.haskell.org/packages/archive/MFlow/0.1.5.3/doc/html/MFlow-For... Take a look and tell me your opinion. I hope that you find it as exciting as me. I´m looking for people to collaborate in the development of MFlow. Although still it is experimental, it is being used in at least one future commercial project. So I have te commitment to continue its development. There are many examples in the documentation and in the package. Alberto
