Play Framework

<h2 id="history">History</h2>
Play was created by software developer Guillaume Bort, while working at Zengularity SA (formerly Zenexity).<a class="footnote-ref" id="fnref:4" href="#fn:4">4</a> Although the early releases are no longer available online, there is evidence of Play existing as far back as May 2007.<a class="footnote-ref" id="fnref:5" href="#fn:5">5</a> In 2007, pre-release versions of the project were available to download from Zenexity's website.<a class="footnote-ref" id="fnref:6" href="#fn:6">6</a>

<h2 id="motivation">Motivation</h2>
Play is heavily inspired by <a href="/facts/ASP.NET_MVC/KFyeWXHx">ASP.NET MVC</a>, <a href="/facts/Ruby_on_Rails/aG5P6uon">Ruby on Rails</a> and <a href="/facts/Django_(web_framework)/TjPPmvSg">Django</a> and is similar to this family of frameworks. Play web applications can be written in Scala or Java, in an environment that may be less <a href="/facts/Java_Platform%2c_Enterprise_Edition/7AAStd35">Java Enterprise Edition</a>-centric. Play uses no Java EE constraints. This can make Play simpler to develop compared to other Java-centric platforms.<a class="footnote-ref" id="fnref:21" href="#fn:21">21</a>
Although Play 1.x could also be packaged as <a href="/facts/WAR_(Sun_file_format)/KohLDBAw">WAR</a> files to be distributed to standard Java EE <a href="/facts/Application_server/wHYtgYK5">application servers</a>,<a class="footnote-ref" id="fnref:22" href="#fn:22">22</a> Play 2.x applications are now designed to be run using the built-in Akka HTTP or <a href="/facts/JBoss_Netty/omxVyJh2">Netty</a> web servers exclusively.

<h2 id="major-differences-from-java-frameworks">Major differences from Java frameworks</h2>
<ul><li><a href="/facts/Stateless_protocol/TgJncyPa">Stateless</a>: Play 2 is fully <a href="/facts/Representational_state_transfer/Q58zfr5h">RESTful</a> – there is no Java EE session per connection.</li>
<li>Integrated unit testing: <a href="/facts/JUnit/zlddF9S2">JUnit</a> and <a href="/facts/Selenium_(software)/ebewybjJ">Selenium</a> support is included in the core.</li>
<li><a href="/facts/Application_programming_interface/GMlN4vUr">API</a> comes with most required elements built-in.</li>
<li><a href="/facts/Asynchronous_I%2fO/6A7V3P89">Asynchronous I/O</a>: due to using Akka HTTP as its web server, Play can service long requests asynchronously rather than tying up HTTP threads doing business logic like Java EE frameworks that don't use the asynchronous support offered by Servlet 3.0.<a class="footnote-ref" id="fnref:23" href="#fn:23">23</a></li>
<li>Modular architecture: like Ruby on Rails and Django, Play comes with the concept of modules.</li>
<li>Native Scala support: Play 2 uses Scala internally but also exposes both a Scala API, and a Java API that is deliberately slightly different to fit in with Java conventions, and Play is completely interoperable with Java.</li></ul>
<h2 id="testing-framework">Testing framework</h2>
Play provides integration with test frameworks for <a href="/facts/Unit_testing/SYoGGS3T">unit testing</a> and <a href="/facts/Functional_testing/2VudQTaz">functional testing</a> for both Scala and Java applications. For Scala, integrations with Scalatest and Specs2 are provided out-of-the-box and, for Java, there is integration with <a href="/facts/JUnit/zlddF9S2">JUnit</a> 4. For both languages, there is also integration with <a href="/facts/Selenium_(software)/ebewybjJ">Selenium (software)</a>. <a href="/facts/SBT_(software)/69mUcxqL">SBT</a> is used to run the tests and also to generate reports. It is also possible to use code coverage tools by using sbt plugins such as <a href="https://github.com/scoverage/sbt-scoverage">scoverage</a> or <a href="https://github.com/sbt/jacoco4sbt">jacoco4sbt</a>.

<h2 id="usage">Usage</h2>
In August 2011, <a href="/facts/Heroku/yKTy97oV">Heroku</a> announced native support for Play applications on its <a href="/facts/Cloud_computing/guhg0FGV">cloud computing</a> platform.<a class="footnote-ref" id="fnref:24" href="#fn:24">24</a> This followed module-based support for Play 1.0 on <a href="/facts/Google_App_Engine/DyPrUG6J">Google App Engine</a>, and documented support on <a href="/facts/Amazon_Web_Services/UFVN2796">Amazon Web Services</a>.<a class="footnote-ref" id="fnref:25" href="#fn:25">25</a>
As of October 2013<a href="https://en.wikipedia.org/w/index.php?title=Play_Framework&action=edit">[update]</a>, the Play Framework was the most popular Scala project on <a href="/facts/GitHub/n1hNCsc3">GitHub</a>.<a class="footnote-ref" id="fnref:26" href="#fn:26">26</a>
In July 2015, Play was the 3rd most popular Scala library in GitHub, based on 64,562 Libraries. 21.3% of the top Scala projects used Play as their framework of choice.<a class="footnote-ref" id="fnref:27" href="#fn:27">27</a>
Corporate users of the Play Framework have included <a href="/facts/Coursera/5Kp5AIuX">Coursera</a>, <a href="/facts/HuffPost/91nLV4zo">HuffPost</a>, <a href="/facts/Hootsuite/8W9fPptJ">Hootsuite</a>, <a href="/facts/Janrain/bA55dDod">Janrain</a>, <a href="/facts/LinkedIn/Iq2IcNMt">LinkedIn</a>, and <a href="/facts/Connectifier/GyKyu8AW">Connectifier</a>.<a class="footnote-ref" id="fnref:28" href="#fn:28">28</a>
