Ada Web Application is a framework to build high performance secure web applications. The major change of this new release is a better integration with the Alire package manager. The crates are in the process of being integrated in the Alire Community Index but meanwhile a dedicated index can be used to access the latest AWA crate definitions. Another interesting feature introduced in the new version is the support for Embedded Web Server as an alternative to the Ada Web Server.
AWA is architectured arround modules and plugins that allow to build, re-use and extend modules made of Ada code, Web pages or Javascript.
AWA provides a set of ready to use and extendable plugins that are common to many web application. This includes managing the login, authentication, users, permissions, a mail plugin, a blog plugin, a Javascript light editor.
AWA uses an Object Relational Mapping that helps in writing Ada applications on top of MySQL or SQLite databases. The ADO framework allows to map database objects into Ada records and access them easily.
AWA integrates a configurable event service which allows plugins to easily interact and connect with each other (either synchronously or asynchronously). The event service provided by AWA is heavily inspired from the Java Message Service.
To learn more on how to create easily a web application using AWA, look at the 4 minutes video.
The Atlas Web Application Demonstrator is a demonstration of an application using this AWA framework. Sources of the Atlas demonstrator are available on GitHub project: Atlas.
