This is a simple demo application that demonstrates the following stack working together:

• Built with Bazel (0.2.2)
• Served with Undertow (Java web server)
• Javascript compiled with Closure Compiler in ADVANCED mode built using the Closure rules
• Dependencies specified using ES6-style modules (goog.require, goog.module, goog.defineClass)
• Closure templates, on the server (Java) and the client (compiled to Javascript)
• CSS built with Closure Stylesheets, minified and using class renaming

Setting up a new project

These were a couple steps I had to take to get everything working.

Bootstrap the BUILD / WORKSPACE

Like most Java libraries, Undertow supplies Maven artifacts. I converted that to Bazel using the generate_workspace command:

bazel run //src/tools/generate_workspace -- \
     -a io.undertow:undertow-core:1.2.11.Final \
     -a io.undertow:undertow-servlet:1.2.11.Final \
     -a io.undertow:undertow-websockets-jsr:1.2.11.Final

Copy the resulting WORKSPACE and BUILD files into your project.
