Grails Diary - week 30 in 2016 - GR8Conf US Edition

This edition is heavily influenced by GR8Conf US, that just took place. Lots of slides, tweets and news.

Grails 3.1.10 was released live from GR8Conf US, with a fair number of annoing bugs fixed

In the 2.10 series of the Asset Pipeline plugins, David Estes has added support for .js.es6 and jsx-asset-pipeline native.

Dan Woods is givin a presentation on "High Performance Microservices with Ratpack and Spring Boot" at Spring One, and is sharing some of his findings on Ratpack + Spring Boot + Async PostgreSQL.

Graeme Rocher has made a RxJava for Grails plugin, that helps you build reactive applications. He has also made an example of a controller using it, and a thorough user guide.
Also in the RxJava for Grails department, another Gist by Graeme, showing Grails Async Comet Example

Adam L. Davis has updated the "Learning Groovy" book, and it is available for pre-order on Apress.

Jorge Aguilera has shared a first take on how to setup CI for a Grails 3 project in Gitlab. Checkout the Grails.gitlab-ci.yml file

Kyle Boon and Craig Burke are having quite a competition on who gets the most mentions in the Grails Diary. I try to include the relevant issues in this blog, but to even out the score, I'm sorry for the spam like references in the end of this edition :)

Caster.io has a free lesson on Hot to Create a Gradle Plugin by Annyce Davis.

Th eGroovy Podcast did an episode live from GR8Conf US, featuring a large range of the speakers, reflecting on the conference, and news from the Groovy Ecosystem. Annyce Davis has also written a GR8Conf US 2016 Recap .

@gr8conf Interview with @ApacheGroovy core comitter @JochenTheodorou at #gr8conf eu 2016. @canoo http://youtu.be/c5BwFwawFBo?a
@sbglasius @craigburke1 @kyleboon @GR8ConfUS but Craig did not want to put @graemerocher on the right side.... #chicken
@sbglasius @craigburke1 vs @kyleboon in one pic @GR8ConfUS https://t.co/swbs4KH0pF
@wbucksoft Can’t agree more with @craigburke1 about locking exact NPM versions, the JS world is not very safe about SemVer & breaking changes #gr8conf
@sbglasius @craigburke1 talk on "AngularJS in Grails" starts with @kyleboon bashing - it's pure ?? @GR8ConfUS #gr8conf
@RyanVanderwerf At @craigburke1 talk on grails and angular, he had to clear up something #kylebooneisterrible #gr8conf @kyleboon https://t.co/SvclNe5aia
@codeJENNerator Right now at #gr8confus @johnrengelman from @objectpartners is talking about Ratpack Beyond the Web #gr8conf https://t.co/VSvxrIZ7EE
@kyleboon "what did I do wrong?" should be the name of all of @danveloper's talks
@johnrengelman @kyleboon @danveloper except for the semicolons in a groovy file.
@kyleboon "if youre a programmer you'll be able to figure out ratpack" says @danveloper. guess you don't need his book.
@dr_pompeii #Gradle forums community rocks!
@johnrengelman My first web framework was non-blocking. How about you? @ratpackweb https://t.co/PY77zOXhMa
@wbucksoft So much this. Do vanilla Spring Boot if you love writing lots of boilerplate code, but I’ll take Grails every time https://twitter.com/danveloper/status/758782093618847745
@danveloper “Spring Boot is 'Grails Lite’. At best.” - @kenkousen #gr8conf
@johnrengelman Some real love for @ratpackweb from @kenkousen during his keynote at @GR8ConfUS #ThanksKen
@danveloper “Ratpack is the ultimate in asynchronous, non-blocking I/O, Java 8 features [for web apps]” - @kenkousen #gr8conf // @ratpackweb
@sbowman96 @ObjectComputing @GR8ConfUS Caught 6 of the OCI @grailsframework core team all in 1 spot! https://t.co/SdXSC5VrxV

@andrewreitz_ I learned how to program grails! https://t.co/JXKOFAlvFI
@kyleboon I came to @craigburke1's talk to learn about the serious topic of groovy DSLs and but the information about @DaneCook is a welcome addition
@rpalcolea And yes… @kenkousen showed a nice example of gradle task using #groovylang that couldn’t be possible with Kotlin #gr8confus
@jtuberville Excited about asynchronous REST client with RxGORM #grails #gr8conf #RxAllTheThings
@jeffscottbrown During @graemerocher's GR8 keynote this morning: "How many of you are using Grails 3?" Great majority of hands go up! #grailsfw #gr8conf

@kyleboon Everyone is excited to learn about @ratpackweb in @marcinerdmann's workshop today at @GR8ConfUS
@GR8ConfUS Good Morning GR8Conf! https://t.co/cRghVuFOeM

@kyleboon Have it on good authority that @craigburke1 plans to disparage me during his @GR8ConfUS talk this week. His h8 must not be allowed to stand.
