Переключение отладки и флагов функций

Sometimes the same code must act differently per environment. Flags let you switch behavior without rewriting logic.

Debug mode shows full tracebacks and auto-reloads on code changes. It is a huge help locally and a danger in production.

The interactive debugger can run arbitrary code from the browser. Keep DEBUG off in production, always.

Let your environment decide. Read DEBUG from an env var so dev turns it on and prod leaves it off.

A feature flag is a boolean that turns a feature on or off without a redeploy. Ship code dark, then flip it live.

Check the flag from app.config inside a view and branch your response. One toggle controls the whole rollout.

Back a flag with an env var so different deployments enable different things from the environment, not the code.

Flags let you enable a feature for staging first, then production. A bad release is one flag flip away from off.

Remember env vars are strings, so "False" is truthy. Compare explicitly to avoid a flag that is always on.

Old flags become clutter. Remove a feature flag once the feature is fully rolled out and stable.

Both are toggles, but DEBUG governs framework behavior while feature flags govern your own app logic. Keep them separate.

You drove DEBUG from config, added env-backed feature flags, parsed booleans safely, and kept flags tidy over time. 🚦
