Redux-Zero Loading Middleware.

A redux middleware to handle global loading fully compatible with redux and redux-zero

Usage

Redux loading middleware set a loading state for every unresolved action that returns a promise, after promise resolution, it set's loadings state to false. Also it chains action unresolved promises that runs within 200ms threshold, and set loading to false only when every promise is done.

Install

npm install redux-loading-middleware --save

Add to your redux-zero project

import createStore from "redux-zero";
import { applyMiddleware } from "redux-zero/middleware"
import loadingMiddleware from 'redux-loading-middleware';

const initialState = {
  todos: [],
  loading: false
};

const middlewares = applyMiddleware(loadingMiddleware);
const store = createStore(initialState, middlewares);

export default store;

Add to your redux project

import { createStore, applyMiddleware } from 'redux';
import loadingMiddleware from 'redux-loading-middleware';
import loadingReducer from 'redux-loading-middleware/loadingReducer';
import thunk from 'redux-thunk';

const initialState = {
  todos: [],
  loading: false
};

const store = createStore(
  loadingReducer,
  applyMiddleware(loadingMiddleware, thunk) // loadingMiddleware must be placed before thunk
);

export default store;

Skipping loading

To skip loading, just set global skipLoading variable to true. To enable loading, set global skipLoading to false.

// redux-zero exemple
const actions = () => ({
    getSomeDataFromServer: (state) => {
        state.setState({ skipLoading: true })

        return myRequest()
            .then(() => ({ skipLoading: false }))
            .then(resp => resp.json())
            // ...
    }
}
