What Scala web-frameworks are available? [closed]

问题

I\'ve just started learning Scala, and the first thing I\'m going to implement is a tiny web application. I\'ve been using Erlang for the last year to implement server-side software, but I\'ve never wrote web applications before. It will be a great experience.

Are there web-frameworks for Scala except for Lift?

Don\'t get me wrong, Lift looks awesome. I just want to know how many frameworks there are so that I can then choose between them. It\'s always a good to have a choice, but I the only thing I found was Lift.

回答1:

I'm very interested in Scala, but I have not used it yet, so with that caveat, the frameworks I am aware of that are not mentioned in HRJ's answer (Lift, Sweet, Slinky) are:

Scalatra, previously Step (on GitHub)
Play 2 (on GitHub)
Pinky

回答2:

I wrote a blog post about this.

To summarise, some of the options are:

Lift
Sweet
Slinky

I finally found that none were suitable for me, and developed my own little "framework". (It is not open-source yet).

回答3:

I like Lift ;-)

Play is my second choice for Scala-friendly web frameworks.

Wicket is my third choice.

回答4:

Following is a dump of frameworks. It doesn't mean I actually used them:

Coeus. A traditional MVC web framework for Scala.
Unfiltered. A toolkit for servicing HTTP requests in Scala.
Uniscala Granite.
Gardel
Mondo
Amore. A Scala port of the Ruby web framework Sinatra
Scales XML. Flexible approach to XML handling and a simplified way of interacting with XML.
Belt. A Rack-like interface for web applications built on top of Scalaz-HTTP
Frank. Web application DSL built on top of Scalaz/Belt
MixedBits. A framework for the Scala progamming language to help build web sites
Circumflex. Unites several self-contained open source projects for application development using the Scala programming language.
Scala Webmachine. Port of Basho's webmachine in Scala, a REST-based system for building web applications
Bowler. A RESTful, multi-channel ready Scala web framework

回答5:

Try Play Framework, which also support Scala.

回答6:

One very interesting web framework with commercial deployment is Scalatra, inspired by Ruby's Sinatra. Here's an InfoQ article about it.

回答7:

I find Unfiltered very interesting https://github.com/unfiltered/unfiltered.

It's mentioned in IttayD's list.

Here is a presentation about it http://unfiltered.lessis.me/#0 and the video http://code.technically.us/post/942531598/doug-tangren-presents-the-unfiltered-toolkit-for

Also here there is an article with more info http://code.technically.us/post/998251172/holding-the-parameter

回答8:

It must be noted that there is also a considerable interest in Wicket and Scala. Wicket fits Scala suprisingly well. If you want to take advantage of the very mature Wicket project and its ecosystem (extensions) plus the concise syntax and productivity advantage of Scala, this one may be for you!

回答9:

Play is pretty sweet.

It is now production ready. It incorporates: a cool template framework,automatic reloading of source files upon safe, a composable action system, akka awesomeness, etc.

Its part of the Typesafe Stack.

Having used it for two projects, I can say that it works pretty smoothly and it should be something to consider next time you are looking to learn new web frameworks.

回答10:

I tend to use JAX-RS using Jersey (you can write nice resource beans in Scala, Java or Groovy) to write RESTul web applications. Then I use Scalate for the rendering the views using one of the various template languages (JADE, Scaml, Ssp (Scala Server Pages), Mustache, etc.).

回答11:

There's a new web framework, called Scala Web Pages. From the site:

Target Audience

The Scala Pages web framework is likely to appeal to web programmers who come from a Java background and want to program web applications in Scala. The emphasis is on OOP rather than functional programming.

Characteristics And Features

Adheres to model-view-controller paradigm
Text-based template engine
Simple syntax: $variable and <?scp-instruction?>
Encoding/content detection, able to handle international text encodings
Snippets instead of custom tags
URL Rewriting

回答12:

Prikrutil, I think we're on the same boat. I also come to Scala from Erlang. I like Nitrogen a lot so I decided to created a Scala web framework inspired by it.

Take a look at Xitrum. Its doc is quite extensive. From README:

Xitrum is an async and clustered Scala web framework and web server on top of Netty and Hazelcast:

It fills the gap between Scalatra and Lift: more powerful than Scalatra and easier to use than Lift. You can easily create both RESTful APIs and postbacks. Xitrum is controller-first like Scalatra, not view-first like Lift.
Annotation is used for URL routes, in the spirit of JAX-RS. You don't have to declare all routes in a single place.
Typesafe, in the spirit of Scala.
Async, in the spirit of Netty.
Sessions can be stored in cookies or clustered Hazelcast.
jQuery Validation is integrated for browser side and server side validation. i18n using GNU gettext, which means unlike most other solutions, both singular and plural forms are supported.
Conditional GET using ETag.

Hazelcast also gives:

In-process and clustered cache, you don't need separate cache servers.
In-process and clustered Comet, you can scale Comet to multiple web servers.

Follow the tutorial for a quick start.

回答13:

There's also Pinky, which used to be on bitbucket but got transfered to github.

By the way, github is a great place to search for Scala projects, as there's a lot being put there.

回答14:

I'd like to add my own efforts to this list. You can find out more information here:

brzy framework

It's in early development and I'm still working on it aggressively. It includes features like:

A focus on simplicity and extensibility.
Integrated build tool.
Modular design; some initial modules includes support for scalate, email, jms, jpa, squeryl, cassandra, cron services and more.
Simple RESTful controllers and actions.

Any and all feedback is much appreciated.

UPDATE: 2011-09-078, I just posted a major update to version 0.9.1. There's more info at http://brzy.org which includes a screencast.

回答15:

Both Sweet and Slinky seem to be unmaintanted for about a year. Sweet Maven repo sweetsoftwaredesign.com is dead so there's even no way to download dependencies.

回答16:

Note: Spiffy is outdated.

<plug>

Spiffy:

is written in Scala
uses the fantastic Akka library and actors to scale
uses servlet API 3.0 for asynchronous request handling
is modular (replacing components is straight forward)
uses DSLs to cut down on code where you don't want it
supports Scalate and Freemarker for templating

Spiffy is a web framework using Scala, Akka (a Scala actor implementation), and the Java Servlet 3.0 API. It makes use of the the async interface and aims to provide a massively parallel and scalable environment for web applications. Spiffy's various components are all based on the idea that they need to be independent minimalistic modules that do small amounts of work very quickly and hand off the request to the next component in the pipeline. After the last component is done processing the request it signals the servlet container by "completing" the request and sending it back to the client.

回答17:

You could also try Context. It was designed to be a Java-framework but I have successfully used it with Scala also without difficulties. It is a component based framework and has similar properties as Lift or Tapestry.

回答18:

I have stumbled upon your question a few weeks back, but since then also learned about Circumflex. This is a nice, minimal framework that is therefore easy to learn, and it has pretty good documentation available as well.

Beside it's minimal-ness, it also claims to work well with other libraries and lets you use your own implementation of things when you need it.
