2026-03-26Use Quarkus Quinoa for serving web UI (#391)vincent van beek
* refactor(web): Migrate to Quarkus 3 This commit updates the OpenDC web server to use Quarkus 3, which changes annotations to use the Jakarta namespace for annotations. * refactor(web): Configure runtime variables for web UI This commit updates the web UI to propagate runtime variables via the next-runtime-env package. Before, we would need to replace the variables in the generated sources by Next.js, next-runtime-env works by loading a JavaScript file when opening the OpenDC web UI which contains the configuration of the web app. * refactor(web): Migrate to Quarkus Quinoa This commit updates the OpenDC web server to make use of Quarkus Quinoa for serving the web UI. This allows us to deprecate the complex Quarkus extension for serving the web UI. * refactor(web): Move web UI into Quarkus web app This commit moves the web UI into the Quarkus web server module to ensure we follow Quarkus Quinoa's conventions. * refactor(web): Merge Quarkus extension into single module This commit merges the existing Quarkus extensions into a single module to prevent build complexity. * refactor(web): Migrate web proto to Java This commit migrates the web protocol to Java and removes the dependency on Jandex Gradle. * refactor(web): Migrate to Quarkus 3 This commit updates the OpenDC web server to use Quarkus 3, which changes annotations to use the Jakarta namespace for annotations. * enable DB schema migration on DEV server * webui is not needed anymore * remove MAINTAINERS is depricated * fix quarkus.quinoa properties * revert properties change, install npm in docker image to allow building the frontend * pin postgres version, this is a best practice. Fix some properties the old ones are depricated. Added properties for local testing * fix build error * :opendc-web:opendc-web-proto:spotlessApply * fix database schema --------- Co-authored-by: Fabian Mastenbroek <mail.fabianm@gmail.com>
