The Dos and Don’ts of Feature Flags
Feature flags provide so much for software organizations: they allow teams to separate code deployment from feature release, test in production, run experiments, and more. However, some rules apply to the feature flagging process that are easy for teams to overlook. I’ve gathered the best practices of feature flags from…
Continuous Integration vs. Continuous Delivery vs. Continuous Deployment
Continuous integration, continuous delivery, and continuous deployment are foundational in today’s agile engineering ecosystem. However, many times they are used interchangeably and often incorrectly. Let’s remove the confusion and settle the differences between continuous integration, continuous delivery, and continuous deployment. What is Continuous Integration? Continuous integration happens when developers regularly…
A Simple Guide to A/B Testing
Product experimentation is the most effective way to determine what works best for end-users. You can measure engagement with a feature and hypothesize ways to improve that engagement, which will ultimately impact one or more critical business metrics. If you’re setting up an experiment, it’s mission-critical to implement A/B testing…
To Canary Release, or Not To Canary Release?
With feature flags, you can control the percentage allocation of users you want to be exposed to a specific feature. This process provides risk mitigation and confirms both usability and scalability. Canary releases, or controlled rollouts, serve as an added layer of protection in case something goes wrong. What is…
Add Tests to Your Feature-Flagged Codebase
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…
Controlled Rollout with React Native and Feature Flags
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…
How to Implement Testing in Production
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,…
Set Up Feature Flags with React Hooks
Everywhere I look lately, I see React Hooks. It’s the new trend that’s taken over the developer world. Hooks are functions that let you hook into state and lifecycle features from functional components. The value here is that they let you use React without classes. This makes for shorter, cleaner…
RIP Release Night
Today we remember the release night. We gather (virtually) today not to mourn the death of the release night, but to celebrate the inception of its replacement. Release nights were once a standard for software development teams to have a set date to release their software to their customers. In…
