redux-timer-middleware

library1.0.0jsnpmunverified

A simple Redux middleware to periodically dispatch actions. Version 1.0.0, no recent updates. Enables starting and stopping named timers via Redux actions, with optional payload, interval, and end-period. No dependencies beyond Redux. Lightweight compared to more complex saga/observable-based solutions.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

timerMiddleware

✓ import timerMiddleware from 'redux-timer-middleware'

✗ import { timerMiddleware } from 'redux-timer-middleware'

Default export, not named.

START_TIMER

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

✗ import START_TIMER from 'redux-timer-middleware'

Named export for action type constant.

STOP_TIMER

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

✗ import STOP_TIMER from 'redux-timer-middleware'

Named export for action type constant.

Shows how to set up redux-timer-middleware, start an infinite timer, and stop it.

import { createStore, applyMiddleware } from 'redux'; import timerMiddleware, { START_TIMER, STOP_TIMER } from 'redux-timer-middleware'; const reducer = (state = {}, action) => state; const store = createStore(reducer, applyMiddleware(timerMiddleware)); // Start infinite timer dispatching 'TICK' every second store.dispatch({ type: START_TIMER, payload: { actionName: 'TICK', timerName: 'myTimer' } }); // Later stop it store.dispatch({ type: STOP_TIMER, payload: { timerName: 'myTimer' } });

Debug

Known issues

gotchatimerName is required for both START_TIMER and STOP_TIMER, but no validation is performed; missing it may cause silent failures.

fix

Always provide a unique timerName string.

affects: 1.0.0

gotchatimerPeriod counts ticks, not milliseconds; setting timerPeriod: 10 dispatches actionName 10 times (once per interval) then dispatches `actionName + '_END'`.

fix

Use timerInterval (in ms) to control tick speed; timerPeriod controls number of ticks.

affects: 1.0.0

gotchaThe middleware does not clean up timers on store unsubscribe; may cause memory leaks if store is recreated.

fix

Manually stop all timers before creating a new store or use a cleanup mechanism.

affects: 1.0.0

Errors

Common errors & fixes

Uncaught TypeError: Cannot read properties of undefined (reading 'apply')

timerMiddleware is a function, but must be applied with applyMiddleware correctly.

fix

import { createStore, applyMiddleware } from 'redux'; createStore(reducer, applyMiddleware(timerMiddleware));

TypeError: actionName is not a string

Missing or non-string actionName in START_TIMER payload.

fix

Ensure payload.actionName is a string like 'MY_ACTION'.

Uncaught ReferenceError: START_TIMER is not defined

Using named import incorrectly or forgetting to import constants.

fix

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