Smalltalk Ajax Frameworks
From Ajax Patterns
Aida/Web is a web server and framework for complex web applications in Smalltalk
AIDA/Web is a web server and framework for complex web applications with integrated Ajax support, rich collection of web components to build web pages programatically, MVC-like separation of presentation from domain, nice looking and bookmarkable url links, with integrated session and security management and many more.
AIDA/Web is known by its simplicity but still allows building most demanding web applications of many sorts. It has everything you need for a real web app, together with Ajax.
It is also a mature one, running web apps in production since 1996. It is used in many intranet business apps from Gas billing system for all gas in Slovenia to logistics management system called e-logis and recently a CMS like system for Quality and Business process management.
Everyone interested is encouraged to:
- look at few screenshots of real AIDA/Web apps,
- see a live demo of AIDA/Web,
- download and install to run your own AIDA/Web server,
- follow a tutorial to start building your own web applications.
- subscribe to a mailing list for further questions, suggestions, advices ...

Seaside is a framework for developing sophisticated web applications in Smalltalk
Seaside provides a layered set of abstractions over HTTP and HTML that let you build highly interactive web applications quickly, reusably and maintainably. Seaside includes:
- Programmatic HTML generation. A lot of markup is boilerplate: the same patterns of lists, links, forms and tables show up on page after page. Seaside has a rich API for generating HTML that lets you abstract these patterns into convenient methods rather than pasting the same sequence of tags into templates every time.
- Callback-based request handling. Why should you have to come up with a unique name for every link and form input on your page, only to extract them from the URL and request fields later? Seaside automates this process by letting you associate blocks, not names, with inputs and links, so you can think about objects and methods instead of ids and strings.
- Embedded components. Stop thinking a whole page at a time; Seaside lets you build your UI as a tree of individual, stateful component objects, each encapsulating a small part of a page. Often, these can be used over and over again, within and between applications - nearly every application, for example, needs a way to present a batched list of search results, or a table with sortable columns, and Seaside includes components for these out the box.
- Modal session management. What if you could express a complex, multi-page workflow in a single method? Unlike servlet models which require a separate handler for each page or request, Seaside models an entire user session as a continuous piece of code, with natural, linear control flow. In Seaside, components can call and return to each other like subroutines; string a few of those calls together in a method, just as if you were using console I/O or opening modal dialog boxes, and you have a workflow. And yes, the back button will still work.
SeasideAsync is an Ajax framework built on top of the default rendering API.
Scriptaculous has a nice Smalltalk API that is automatically mapped to the Scriptaculous prototypes.
