redux-logging

What is Redux Middleware?

• Similar to middleware in other libraries or frameworks

• Adds a way for 3rd parties to introduce their own logic or processing

• Runs between an action being dispatched and when it hits the reducer

Logging Middleware

• Since all state updates happen through Redux actions, we have a centralized point to intercept and log state changes

• All actions having a serializable type gives us a human readable name to understand the intent of state changes

• Pure reducers make logging the before state and after state very useful and simple
