How to use Dart's dev_compiler for simple libs?

Question

I am experimenting with Dart's dev_compiler. I think I am missing a couple of steps how to get it working in a browser. Currently all the resources I found regarding it are: Usage

What I'd like to do is:

1. Create a simple single class library package in Dart
2. Compile it to ES6
3. Use that compiled library in Canary from JS

Problems:

• running dartdevc -o outputdir lib/mylib.dart prompts me to specify the --runtime-dir option. What should that directory be? I use Win dev machine, I specified it to be Pub\Cache\hosted\pub.dartlang.org\dev_compiler-0.1.1+1\lib\runtime
• After that, compilation succeeds, however in the compiled .js file there are a references to a dart variable. I assume this should be the one defined in dart_runtime.js. This brings me to the question: what exactly do I have to import in an HTML file to get my transcompiled dart lib work? (scripts srcs)

For now I did not get as far as to use the transcompiled library from a browser. Any tips how to do that would be appreciated.

Update:

I wrote a little post about my experiences with dev_compiler: dev_compiler experiment

This easiest way to play around with this is to use the "server" mode:

dartdevc -o outputdir --server foo.dart

That should generate a foo.html in the output directory that shows you what gets linked in.

For now, this will bring in all the Dart libraries - regardless of what your class actually uses. You may find that you only need a small subset to run your code.
