The hype is on for lightweight “Javascript in the server” alternatives to the proven Java J2EE and LAMP stacks. Even last year’s cool Ruby/Rails-style web frameworks are being dissed by the Node.js crowd. Is this where web development is going or is it just a hype bubble? Presumably thousands of startups are already all-in on server-side Javascript and we’re looking forward to some real-world learnings and comparisons. Meanwhile we’re left guessing how this will all play out.
Is Node.js a toy for script kids who don’t understand server programming or a real web application server framework? The scalability debate rages across the web (An entertaining example: Node.js is cancer), but it seems clear that, even though hosted solutions might provide pieces such as monitoring, security and scalability the missing Node.js on its own can’t replace established web application infrastructure.

The fix is documented here: https://github.com/mxcl/homebrew/issues/4782
It consists of adding a line in the readline formula file: /usr/local/Library/Formula/readline.rb right before the system command:
inreplace 'support/shobj-conf', 'darwin[89]*|darwin10*)', 'darwin[89]*|darwin1[01]*)'

After having created a standard maven project for the guestbook app as described in this previous post, running the application in Intellij Idea is pretty straight forward.
Create the project
Select File > New Project, and create a new project from External Model, Maven by pointing idea to your pom.xml, just as you would to import any other maven project.
Create a Runner
While we are waiting for someone to write a Intellij Idea server component for Google Appengine Java SDK, we have to create a runner for the server, with the following parameters:
Main Class
com.google.appengine.tools.KickStart
VM Parameters
We have to pass this parameter for Appengine to accept loading the tools jar from a non-standard location.
-Dappengine.sdk.root="/Users/<your user>/.m2/repository/com/google/appengine-tools/1.2.0/"
Program Parameters
com.google.appengine.tools.development.DevAppServerMain target/guestbook
Working Directory
/Users/<your user>/dev/google-app-engine/guestbook
Environment Variables
SDK_LIB=/Users/<your user>/dev/google-app-engine/appengine-java-sdk/lib;
SDK_CONFIG=/Users/<your user>/dev/google-app-engine/appengine-java-sdk/config/sdk
-
-
Intellij Runner to start the Google Appengine environment
Run the App
You should se the following in the runner console tab:
