Feature Flags in Angular

A practical example of implementing feature flags in an Angular application — allowing features to be toggled on/off without a new deployment.

Why this matters

In production apps, shipping incomplete features behind a flag lets teams merge code safely, run A/B tests, and do gradual rollouts without blocking the release pipeline.

What's inside

• A lightweight feature flag service using Angular's dependency injection
• Example of conditionally rendering UI based on flag state
• Pattern for combining flags with route guards

Tech used

Angular, TypeScript, RxJS

Key takeaway

This pattern scales well for teams that need to ship work-in-progress features safely alongside stable code — something I've applied in production dashboards serving thousands of active users.
