Code licensed under the framework is available Affero GPL .
This framework can also be used as a standalone programming language: an application being written to the Opa, will be automatically checked on the quality of its code, and then can be automatically generated for similar functionality JavaScript-application. All major aspects of Web development at any level of complexity was originally implemented in this framework: this is sample code frontend and backend, the generation of database queries and options for various model configurations. The developers claim that the development of Opa spent over 100 man-years, not taking into account the code, which was donated by third parties invested projects and research laboratories.
The main features of Opa:
- AJAX and COMET-calls with a transparent JSON-serialized;
- generation of HTML;
- definition of the model using data;
- generate queries to the database (currently only for MongoDB);
- support for event-oriented approach to non-blocking architecture;
- built-in parsers and generators;
- framework uses a strict static typing;
- paid much attention to security issues;
- fast compiler implemented in OCaml.At the end of this summer’s planned release of the next version – Opa 1.1, which will improve the standard library and API, to extend the error messages in the output of the compiler and improve performance Node.js-backend. The developers also say they want to make Opa de facto framework for all corporate JavaScript-applications.
