From code to control: master deployments with Feature Flagging and OpenFeature
This workshop shows how to add a feature to a Java/Angular app using feature flags with OpenFeature. It covers safe releases, error handling, A/B testing, progressive rollouts, targeting, and observability—helping teams decouple deployment from activation and ship faster with less risk.

Shipping code is good. Shipping a new feature without breaking the rest of the system is even better!
Every release today brings the risk of regressions or bad interactions between existing and new functionality. And what about deploying to only a subset of users? That’s even trickier.
Feature flagging decouples code deployment from feature activation, allowing you to turn blocks on or off at runtime without redeploying.
Fortunately, this practice has been growing with open‑source tools and solid engineering habits. However, beyond simple if‑then‑else, most available solutions are proprietary, heavy or costly to set up.
OpenFeature, a CNCF project, offers an open specification for unified feature flagging, usable both server‑ and client‑side regardless of the backing store.
In this workshop we’ll add a new feature to an existing Java/Angular application and drive its activation through feature flags. Along the way we’ll cover key topics: error handling, A/B testing, progressive rollouts, targeting and observability.
By the end, you’ll know how to deliver faster, safer and with confidence.
