use-reducer-logger v1.0.2

use-reducer-logger

A very very basic logger for the useReducer function in the React Hooks API. Inspired by redux-logger.

Usage

1. Install with npm install use-reducer-logger --save-dev or yarn add use-reducer-logger -D
2. Import logger with

import logger from 'use-reducer-logger';

3. Wrap your reducer with logger before passing it to useReducer

const [state, dispatch] = useReducer(logger(reducer), initialState);

See Example

In a Dev Environment

You should only use this in a dev environment. So you could do something like this to apply the logger based on the env.

function reducer(state, action) {
  switch (action.type) {
    case 'increment':
      return {count: state.count + 1};
    case 'decrement':
      return {count: state.count - 1};
    default:
      throw new Error();
  }
}

const [state, dispatch] = (
  process.env.NODE_ENV === 'development' ? logger(reducer) : reducer,
  initialState
);
