No Files. No HTML. Just Smalltalk code!

HttpView2, also known as HV2 or HVHttpView2 is a lightweight web framework, suitable for building RESTful web applications.

It is the engine that powers SqueakMap.

HV2 was created by Goran Krampe, and was developed by Goran Krampe and Giovanni Corriga.

URL-based component activation:

How does this work?

Each part of the URL corresponds to a message understood by an HV2 object.

These methods implement the dispatch and response logic of your application.

For example, let's say

No templates used!
Instead of templates HV2 uses a builder system.

Automatic form handling: no need to name your forms and the fields within them: HV2 will take care of that. The values of a submitted form may be easily retrieved simply by sending a #value message to right objects. This makes form creation as easy as building GUIs!

Small codebase: the whole framework is just a handful of classes.

Getting started

From SqueakMap install in order

Save the image. :)

Now, fire up HelloWorld - read class comment of HVHelloWorld. All samples can be started/stopped on port 8080 by simple sending "startDebug" or "stop" to the class. You can also stop any running sample by sending "stopAll" to any sample class.

HV2 and Seaside

HV2 exploits the HTTP request/response model that Seaside abstracts away. This makes HV2 well suited for RESTful, asynchronous web applications that don't require an high degree of interactivity, while Seaside is ideal for complex, interactive web applications.
