In this episode, we dive into how client-side feature management works, using Fortify as an example. First, we revisit how enabling and disabling features (like registration) work on the server, then explore how to reflect those toggles in the frontend so our users see up-to-date options.
We start with a basic manual feature check for the registration button, show how to hide it on the client when registration is disabled, and test that the route remains inaccessible. Then, realizing that manually adding checks everywhere gets tedious and messy, we refactor our approach. Instead of hardcoding each check, we pull all enabled features from our Fortify config and share that with the client as an object. This makes it easy to show or hide things based on enabled feature keys, all in one place.
As a result, whenever we enable or disable features in our config, the changes are automatically reflected on the frontend, keeping things DRY and organized. We wrap up by mentioning future improvements, like grouping features, but for now, we have a solid, scalable setup for sharing feature flags between backend and frontend.
