Plugin for vuex to run redux-saga

vuex-coolstory

redux-saga is an awesome library that aims to make side effects (i.e. asynchronous things like data fetching and impure things like accessing the browser cache) easier and better.

While originally targetting Redux, redux-saga is actually not strictly tied to redux and do not rely on any internals of it's implementation. Actually redux-saga could be used with Vuex with put effect commiting mutations

This library wraps redux-saga so it can be used as Vuex plugin. It's external interface is similar to middleware provided by redux-saga.

Differences from vuex-redux-saga

vuex-redux-saga not work with latest redux-saga, uses subcribe to commits hook as redux-saga action channel, and looks like abandoned.
This package support latest version of redux-saga, plus also have mapSagaActions() function for your components. To send actions to saga directly, you can use store.sagaDispatch function. store.sagaDispatch is similar to vuex store.dispacth function.

Installation

$ npm install --save vuex-coolstory redux-saga

Usage

import Vue from 'vue';
import Vuex from 'vuex';
import { VuexSaga } from 'vuex-saga';
import { take, put, race, delay } from 'redux-saga/effects';

// simple saga
function* saga() {
    while (true) {
        const { newItem, timer } = yield race({
            newItem: take('addItem'),
            timer: delay(3000)
        });
        if (timer) {
            yield put({
                type: 'appendItem',
                item: 'TIMER'
            });
        } else if (newItem) {
            yield put({
                type: 'appendItem',
                item: newItem.payload.item
            });
        }
    }
}

Vue.use(Vuex);

export default new Vuex.Store({
    state: {
        items: []
    },
    plugins: [
        VuexSaga({
            sagas: [saga] // pass your sagas to plugin
        })
    ],
    mutations: {
        appendItem(state, { item }) {
            state.items = [...state.items, item];
        }
    }
});
