DESCRIPTION:
The strangler software pattern gets
its name from the tree-strangling vines of the Amazon rain forest. These
seemingly benign vines grow up the trunk of an established tree and over many
years the tree is systematically consumed and destroyed, leaving a magnificent
growth of vines where the tree once stood.
The pattern that is the software
equivalent of the vine helps a code base transition from an old crusty
architecture by systematically replacing it. The cardinal rule being that new
code cannot call into the old, only the other way around. If a new feature
requires behavior from the old code, the old code must be ported.
With JRuby enabling Rails on the JVM a similar
approach can be taken. A java web application framework stack, let's say Struts
and Hibernate, can have its view components systematically replaced by Rails
without ever stopping new feature development. With Struts consumed we can set
our sights on the model - systematically replacing Java classes with Ruby ones
and Hibernate persisted objects with ActiveRecord models. Eventually leaving us
with a super-productive, magnificent, Rails ecosystem to live
within.
This talk will cover JRuby integration with Java
and running Rails in the JVM, concluding with the port of a simple Struts /
Hibernate app to Rails. The audience should leave with all the knowledge
necessary to port their own applications to Rails.
