redux-timer-middleware

Simple middleware to dispatch actions periodically

Installation

$ npm i --save redux-timer-middleware

Usage

import timerMiddleware from 'redux-timer-middleware'

applyMiddleware(timerMiddleware)(createStore)

Start Timer

You need to dispatch action START_TIMER and provide in payload:

• actionName (required) - action that will be dispatched each timer tick
• timerName (required) - timer name (need for stop feature)
• actionPayload - payload that will be provided to the actionName
• timerInterval - interval in ms (default 1000)
• timerPeriod - tick count after which timer ends, when timer ends - action name with _END will be dispatched

Stop Timer or Stop multiple timers

You need to dispatch action STOP_TIMER and provide in payload:

• timerName (required) - timer name that we stop
• timerNames [] - timer names in array if we need to stop multiple timers

Examples

Infinite timer:

import {START_TIMER} from 'redux-timer-middleware';

dispatch({
    type: START_TIMER,
    payload: {
        actionName: 'SOME_ACTION_TICK',
        timerName: 'infiniteTimer'
    }
});

With a payload:

import {START_TIMER} from 'redux-timer-middleware';

dispatch({
    type: START_TIMER,
    payload: {
        actionName: 'SOME_ACTION_TICK',
        actionPayload: { /* my cool payload */ },
        timerName: 'infiniteTimer'
    }
});

To stop this timer:

import {STOP_TIMER} from 'redux-timer-middleware';

dispatch({
    type: STOP_TIMER,
    payload: {
        timerName: 'infiniteTimer'
    }
});

Timer that ends after 10 seconds:

import {START_TIMER} from 'redux-timer-middleware';

dispatch({
    type: START_TIMER,
    payload: {
        actionName: 'SOME_ACTION_TICK',
        timerName: 'testTimer',
        timerPeriod: 10
    }
});

After timer ends action with type 'SOME_ACTION_TICK_END' will be dispatched
