How and When to Use Feature Flags in NextJS

Next.js developers can implement feature flags through environment variables, API-driven flags, middleware, or third-party services. For quick implementation, environment variables are the simplest solution, defining flags in .env files and referencing them in code. This allows features to be toggled without new code deployment, though changes require redeployment. The team used this approach to gate new components and experimental features, enabling progress without added complexity.
