Feature management in React.js applications involves techniques like feature flags and toggles, allowing for decoupling of application deployment from feature releases. Gradual rollouts, remote configuration, and audience targeting are key techniques. Increased control and flexibility in feature management provide targeted launches and quick rollbacks, but there are pain points like lack of reviews and approval workflow. Infrastructure as code (IAC) and GitOps are practices that can be combined with feature management. Feature Advisor is a tool that helps with feature management in React applications, focusing on principles rather than the tool itself.

Decouple your releases from deployments, while maintaining full engineering control of your application.

Feature Flagging With React

Today's Talk discusses enabling tests in production, including challenges with staging environments, the use of feature flags for testing, and automating feature flag testing. It also covers running tests in production while ensuring no impact on real users, determining what to test in production, recommended tools and dependencies, and mitigating risks. The importance of testing in production and shifting the testing culture is emphasized, along with the need for a solid automation framework and managing feature flag dependencies.

How do you know your feature is working perfectly in production? If something breaks in production, how will you know? Will you wait for a user to report it to you? What do you do when your staging test results do not reflect current production behavior? In order to test proactively as opposed to reactively, try testing in production! You will have an increased accuracy of test results, your tests will run faster due to the elimination of bad data, and you will have higher confidence before releases. This can be accomplished through feature flagging, canary releases, setting up a proper CI/CD pipeline, and data cleanup. You will leave this talk with strategies to mitigate risk, to better your understanding of the steps to get there, and to shift your company’s testing culture, so you can provide the best possible experience to your users. At the end of the day, we don't care if your features work in staging, we care if they work in production. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Using Feature Flags to Enable Testing in Production

This Talk discusses setting up feature flags with React, which allows for controlled rollouts of new features. Feature flags provide more control without touching the source code and can target specific users or types of users. In React, feature flags can be created and configured using Split.io. Different treatments can be applied to determine if a feature should be shown. Feature flagging provides control and flexibility in development.

As developers, we release features daily – but how do you ensure those features are working properly in production before you release them to all your users? If you ask me, the answer is feature flags! Feature flags are beneficial because they allow you to test your code in production, perform canary releases, and even conduct A/B testing. The power of React makes it easy to implement these flags. We will walk through how to easily create a feature flag in the UI, install dependencies with npm, and implement your feature flag in your react app. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>
