astx-redux-util

The astx-redux-util library promotes several redux reducer composition utilities, which blend multiple reducers together forming a richer abstraction through functional decomposition (i.e. higher-order functions).

Reducer composition is not new. Redux itself provides the innovative combineReducers utility which allows you to fuse individual reducers together to build up the overall shape of your application state.

The most prevalent astx-redux-util utility is reducerHash(), which lets you combine sub-reducers in such a way as to eliminate the switch statement commonly used to delineate action type.

Additionally, astx-redux-util promotes other reducer compositions that can be used in conjunction with one another.

At a Glance

• Getting Started ... installation and access

• Concepts:

  • Basics ... using reducerHash(), eliminate the switch statement commonly found in reducers ("look ma, no switch")

  • Conditional Reduction ... using conditionalReducer(), invoke a reducer only when certain constraints are met ("to reduce or NOT to reduce; that is the question")

  • Joining Reducers ... using joinReducers(), team up multiple reducers to promote higher order functionality ("working together is success" - Henry Ford)

• A Most Excellent Example ... a more complete example employing many of the astx-redux-util utility functions
