SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill enables safe, gradual releases of new features, allowing for experimentation and quick rollbacks to minimize production risks.

Core Features & Use Cases

  • Trunk-Based Development: Integrate features without impacting users until ready.
  • Canary Releases & A/B Testing: Roll out features to a subset of users for testing and feedback.
  • Kill Switches: Instantly disable features in case of production issues.
  • Use Case: You've developed a new checkout flow. Use this Skill to enable it for 1% of users, monitor performance, and gradually increase the rollout percentage if everything looks good.

Quick Start

Use the feature flags skill to enable the 'new-checkout-flow' flag for 10% of users.

Frequently Asked Questions about Feature Flags and Progressive Delivery

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement feature flags for canary releases and A/B testing?▼

Feature flags enable canary releases and A/B testing by allowing you to roll out new functionality to a subset of users. You configure percentage rollouts and user targeting to safely expose features, monitor performance, and gather feedback before a full deployment.

What is the best way to manage trunk-based development without affecting production users?▼

Trunk-based development is managed safely by integrating incomplete features behind feature flags. This allows continuous code integration into the main branch without impacting users until the boolean or multivariate flags are explicitly activated.

Does this feature flag implementation support LaunchDarkly, Unleash, and Flagsmith?▼

Yes, the feature flag implementation integrates directly with LaunchDarkly, Unleash, and Flagsmith. It provides framework-specific examples for React, Node.js, and FastAPI to connect with these providers for managing boolean and multivariate flags.

How do I set up a kill switch to instantly disable a feature in production?▼

A kill switch is set up by configuring a boolean feature flag that controls the feature's activation. If production issues occur, toggling the flag instantly disables the feature for all users, minimizing risk and allowing for immediate rollback.

Can I schedule feature flag activations and percentage rollouts in Node.js?▼

Yes, you can schedule feature flag activations and configure percentage rollouts within Node.js applications. The implementation supports both scheduled activations and gradual percentage-based rollouts to control how new features are exposed to your user base.
