opalang.org - The Opa Language

Description: The open source Opa Framework for JavaScript makes web development rapid and secure.

Example domain paragraphs

Compile and run your Opa application with a single command line

Test your Opa application immediately at http://localhost:8080

Write simultaneously the frontend and backend code , in the same language, within the same module. Even better: the Opa Slicer automates the calls between client and server. No more manually written AJAX calls or value serialization!
