1. Feature toggling Processes Improving Feature
2. Chapter One: Вon't drown into conflicts
4. Code delivering is not a feature delivering
6. function reticulateSplines(){ if( featureIsEnabled("use-new-SR-algorithm") ){ return enhancedSplineReticulation(); }else{ return oldFashionedSplineReticulation(); } }
7. Chapter Two: This is not so unnecessary
8. Feature Toggles (aka Feature Flags) - Pete Hodgson https://martinfowler.com/articles/feature-toggles.html
15. Chapter Three: If + else and in the production
17. function reticulateSplines(){ if( featureIsEnabled("use-new-SR-algorithm") ){ return enhancedSplineReticulation(); }else{ return oldFashionedSplineReticulation(); } }
18. function reticulateSplines(){ if( featureIsEnabled("use-new-SR-algorithm") ){ return enhancedSplineReticulation(); }else{ return oldFashionedSplineReticulation(); } } Point Point Router ?

20. function reticulateSplines(){ if( featureIsEnabled("use-new-SR-algorithm") ){ return enhancedSplineReticulation(); }else{ return oldFashionedSplineReticulation(); } } Point Point Router Gates
21. • Toggle points - contain our code which implement some feature or behavior • Toggle router - choose the correct point depends of the state of feature toggle • Toggle gate - determines the state of feature toggle depends of current context and configuration • Toggle context - describes the current state of system and environment which we use for making decision for determining the state of feature toggle (ENV, session values, headers, current user and etc.) • Toggle configuration - configure which gate we’re using and some specific rules

27. • Releasing separately (and avoiding conflicts) aka Canary Release • ???
28. • Releasing separately (and avoiding conflicts) aka Canary Release • A/B testing • Alfa, Beta testing • Customization for premium users
29. • Managing feature toggles • Moving toggles from one group to other • Continuous Delivering • Testing many branch of states • Saving current feature toggles ENV to error trackers • Avoiding conditionals and feature supporting
30. Hot to save and configure feature toggles • Code • YML • UI
