Editor's Notes
- Welcome.. \nMy name.\nTake a picture!\n
- \n
- Java? Scala? .Net? Web? Ruby on Rails? Django? Other languages.\n
- So, How are we going to go from nothing to the cloud in 45 minutes. \nHeroku a cloud application platform supporting Play Framework\n\n
- - integrates the components and APIs you need for modern web application development.\n- aims to optimize developer productivity\nStateless: Play is fully RESTful - there is no Java EE session per connection. This makes Play more outwardly-scalable than many other frameworks.\n\nIn May 2008 the first published code for 1.0 appeared on Launchpad.[6] This was followed by a full 1.0 release in October 2009.[7]\nPlay 1.1 was released in November 2010 after a move from Launchpad to GitHub. It included a migration fromApache MINA to JBoss Netty, Scala support, native GlassFish container, an asynchronous web serviceslibrary, OAuth support, HTTPS support and other features.[8]\nPlay 1.2 was released in April 2011. It included dependency management with Apache Ivy, support forWebSockets, integrated database migration (reversion is not implemented yet[9]), a switch to the H2 database and other features.[10]\nPlay 2.0 was released on March 13, 2012 [11] in conjunction with Typesafe Stack 2.0. [12]\n[edit]\n\n
- Hot reloading - decrease the waiting time during development, and increase the DX - developer experience.\n
- Here are some of the built in components\nRegarding modules - Play is designed to work with modules, so the community will create modules, but some will be included in the framework from the start \n\n\n
- \n
- So this is what we will do on our live coding session\n
