Play 2 – Some People Don't Seem to Realize What They Have
There’s a very active discussion going on at the moment regarding Play 2 over the Google Group, and it’s really polarising opinion. A lot of people still seem to be under the impression that Play 2 is only a Scala framework, with a crappy half-baked Java API bolted on as an afterthought. It’s not – both Java and Scala are first class citizens in Play 2, and it amazes me that so much FUD is surrounding this issue.
People also seem to be viewing it as a usurper to Play 1, and that Play 1 is now a dead framework walking.
I’m going to do the laziest thing possible in a blog, and reproduce my contribution to this argument (with added emphasis on some parts):
I’ve got projects in production using Play 1.x (including a huge one that took over a year to write – and which would have taken much longer without Play). Do I think Play 1 is going to die? No – because lots of people, including Zenexity, have got lots of projects running on Play 1. For them to let it die would be like shooting themselves in the foot – got this from Guillaume and Sadek directly last night.
Do I want to port those projects over to Play 2? No – because they’re running perfectly well on Play 1, and are now in maintenance mode.
What will I choose for my next project? Probably Play 2, unless the code requires deployment as a war, and this seems to be a point that a lot of people are missing. There’s nothing that can be done in Play 1 that can’t be done in Play 2, and if you want, you can do it all in Java. My Scala is still pretty much at the beginning of the learning process, but this in no way discourages me from coding with Play 2 because *I don’t need to know Scala*. For a comparison, how many people knew Groovy before they started using Play 1 Groovy templates?
Backwards compatibility is important, and that’s why Play 1.2.5 (and .6 and .7 and .n) will be backwards compatible. For Play 2 to not be able to move past what has come before would maybe win some fans in the short term, people who want to be able to drop their Play 1 projects into Play 2 without a code change, but in the mid- to long-term it would have been obsolete before it even started.
There is no Play Scala or Play Java – it’s Play JVM, and that’s what it always has been!
