Feature flagging is a technique development teams deploy to enable easy switches between codepaths in their systems, at runtime. In simpler terms, they’re control structures that toggle on and off the code inside them. Dev teams use feature flags for a wide variety of purposes, from canary releases to A/B…

Software testing is usually a point of friction for software development teams. Feature flags create an added layer of complexity that you need to account for. So how can we make the process of testing in a feature-flagged codebase easier?  Isolate Tests to Reduce the Scope of the System Under…

Creating new microservices individually via feature flags ensures a low-risk release that will be easy on your devs, network administrators, and end-users

Controlled rollouts, also called canary releases, or percentage rollouts, are a vital part of software releases. With controlled rollouts, you can release your new feature to a small subset of users, verify proper functionality, and then slowly roll the feature out to your entire user base once you know it…

Develop a small application programming interface with Node.js and Express, and deploy feature flags to toggle functionality.

Feature toggling is a powerful technique you can use to hide or disable parts of an application. Today, we’ll walk you through implementing a feature toggle (often called a feature flag) in Spring Boot. By the end of the post, you’ll have learned not only how to get started with…

Testing in production is becoming more and more common across tech. The most significant benefit is knowing that your features work in production before your users have access. With feature flags, you can safely deploy your code to production targeting only internal teammates, test the functionality, validate design and performance,…

Learn how to create a basic CRUD app using Spring Boot and Angular to release features to production quickly and safely.

Learn to branch by abstraction, a pattern used for making large-scale changes gradually while continuing to release your application, using feature flags
