Redux Logger - Shell-Bash

Introduction

Redux Logger is a middleware library for Redux that logs actions and the resulting state changes. It is especially useful for debugging and understanding how your Redux store is being updated.

Features
  • Logs every Redux action and the resulting state changes.
  • Shows a colored diff of the state changes for easy viewing.
  • Allows customizing the log output with options such as collapsed or expanded output, custom logger functions, and more.
Installation

To install Redux Logger into your project, run the following command:

npm install redux-logger --save-dev
Usage

To use Redux Logger in your Redux store, simply apply it as middleware:

import { createStore, applyMiddleware } from 'redux';
import logger from 'redux-logger';
import rootReducer from './reducers';

const store = createStore(
  rootReducer,
  applyMiddleware(logger)
);

You can also customize the logger with options:

import logger from 'redux-logger';

const loggerMiddleware = logger({
  // options here
});
Options

Here are some example options you can use to customize the logger:

| Option | Description | | --------- | ----------- | | collapsed | Boolean to collapse log output by default. | | colors | Object that defines color schemes for the output. | | level | String that specifies log level ('log', 'console', or custom function). | | titleFormatter | Function that formats the title of the log output. | | timestamp | Boolean to display timestamp in log output. |
