Question 1

redux-logger vs Redux DevTools which is better for debugging?

Accepted Answer

Redux Logger is ideal for custom, in-console logging during development with real-time insights, while Redux DevTools offers a browser extension with time-travel debugging and state inspection. Use Logger for quick, formatted logs and DevTools for advanced state manipulation and history tracking.

Question 2

how to filter out certain actions in redux-logger?

Accepted Answer

Use the predicate option to specify a function that returns false for actions you want to exclude. For example, set predicate: (getState, action) => action.type !== 'AUTH_REMOVE_TOKEN' to skip logging authentication actions, as shown in the recipes.

Question 3

how to disable redux-logger in production?

Accepted Answer

Conditionally add the middleware only in development by checking process.env.NODE_ENV. The README provides a recipe to push logger into middlewares only if NODE_ENV is 'development', ensuring it's omitted in production builds.

Question 4

redux-logger custom colors example

Accepted Answer

Set the colors option with functions that return color strings for different log parts, such as title or prevState. Refer to the defaults in the options description, where you can define color getters based on action or state to enhance visual clarity.

Question 5

redux-logger immutable.js how to use

Accepted Answer

Use the stateTransformer option to convert Immutable objects to plain JSON. The README includes recipes for both scenarios: without combineReducers using Iterable.isIterable, and with combineReducers to handle nested state, ensuring readable logs.

Question 6

does redux-logger work with batched actions?

Accepted Answer

Yes, but it requires custom configuration. The README provides a recipe using actionTransformer to handle batched actions by modifying the payload, allowing proper logging of multiple actions in a single dispatch for libraries like redux-batched-actions.
