Dev's third java framework in 10 years goes all-in on json-only comms to escape jsp nightmares in japan's endless si grind

A Japanese developer has created a lightweight Java framework called SIcore, designed for Japan's "SI" projects, with a core principle of "JSON-only communication" between the browser and server. This approach, implemented for the third time in 10 years, limits communication to JSON format, with requests sent as JSON or URL parameters and responses returned in JSON format only. The framework separates roles and page transitions, differing from traditional JSP-style approaches, and offers benefits such as reduced communication volume, clear separation of responsibilities, and easier state preservation. However, it also increases the risk of browser-side errors and requires a separate approach for file uploads. The developer plans to discuss handling static HTML in the next article, with the framework available on GitHub. This framework aims to build web business applications quickly and consistently, with potential implications for the industry's approach to web development and communication protocols.
