Important: Genie v4 is not compatible with Julia version 1.8 and up. For Julia 1.8 and up support, please use Genie 5. If you have applications developed with Genie v4, please upgrade them to Genie 5, by following the migration guide provided in the Genie docs.
Julia data dashboards powered by Genie
Genie is a full-stack web framework that provides a streamlined and efficient workflow for developing modern web applications. It builds on Julia's strengths (high-level, high-performance, dynamic, JIT compiled), exposing a rich API and a powerful toolset for productive web development.
Due to an issue caused by the removal of some APIs in Julia 1.8, **Genie v4 apps can not run on Julia 1.8**. This results in a `LoadError: UndefVarError: modules_warned_for not defined` exception when loading a Genie v4 app on Julia 1.8 and above.
Please follow the Genie v4 to Genie v5 migration guide to update your app and make it compatible with Julia 1.8 and above.
