Framework for aspect-driven & context-aware services

Library prototypes of the framework for aspect-driven & context-aware services in Java, Python and JavaScript.

See the framework in action in the example e-commerce application.

For library user manual, please refer to the specific implementation folders java/, nodejs/ or python/.

Building the libraries and running the example

You can build all the libraries at once and run the example e-commerce system simply by running the build-and-run-all.sh script.

Make sure your Docker deamon is running and has enough RAM (about 2GB should suffice).

$ ./build-and-run-all.sh

Testing

For testing, you can see the .travis.yml file and use the commands listed there. Link to results of CI tests are on the top of this page. You can also refer to the READMEs in the specific library for concrete testing commands.
