Seaside Seaside is a highly productive web development framework written in Smalltalk. Avi Bryant initially developed Seaside in Ruby in a framework called Iowa. Early Ruby continuations had a few problems so the original author of Seaside moved to Smalltalk. Since then he s been improving the framework and using it to deliver commercial applications. Seaside has a few defining characteristics Seaside renders HTML programmatically. Most Java frameworks render HTML with templates. I don t know enough to advocate one method over another but it s certainly different and it works well in Seaside s model. Seaside has a model for components. A Seaside component manages user interface state and renders itself in HTML. Seaside components are highly reusable and they let you think in increments smaller than a page. Seaside makes it easy to manage a link. You can specify a link with a code block so links don t get out of sync. The framework manages them for you. Seaside is modal. This is the author s word for a continuation server approach. Seaside lets you express one web page or multipage web flows in a single method. Seaside s debugging is the best I ve ever seen. From within the browser you can open a web-based Smalltalk browser complete with code. You can also inspect the values of all the objects in the application. Of course you also get the advantages of using a highly dynamic language. You get a rapid feedback loop interactive interpretation as needed and full access to Smalltalk s excellent environments. I used the Squeak IDE for examples in this chapter. Squeak is a dialect of Smalltalk popularized by Disney. . A Little Smalltalk Syntax Before we get too far you should know a little Smalltalk syntax. Don t worry. I m not saying that Smalltalk is the next great language I just want you to see the power of the best continuations-based server. If you want to follow along download the Squeak IDE from http download . Start Squeak .
