Why use react-redux-loading-bar (and when not to)

react-redux-loading-bar is a lightweight, deterministic top-of-page progress indicator that wires into Redux through a reducer and action creators. It is not a full-featured spinner library; it’s designed for signal-based progress (start/stop increments) tied to Redux actions. If you need animated chunked progress for file uploads or rich UX telemetry, pair it with a more advanced progress library or implement custom logic.

The value proposition: it centralizes loading state across the app, works well with middleware and is predictable — you dispatch show/hide actions instead of sprinkling local state. That makes it excellent for classic Redux apps, simple APIs and when visible progress gives users confidence.

Downsides: it’s not a magic “track every network request” solution — you still need to integrate it with your async middleware (thunk/saga/RTK Query) or network layer. Also, for server-side rendering consider hiding it and hydrating client-side to avoid mismatch.

Installation and quick start (5 minutes)

Install via npm or yarn. Link anchors below lead to official resources in case you’d like to see the source or package metadata.

npm install react-redux-loading-bar
# or
yarn add react-redux-loading-bar

Minimal wiring: add reducer, insert <LoadingBar /> into your app shell and dispatch show/hide around async work. Example pattern:

// rootReducer.js
import { combineReducers } from 'redux'
import { loadingBarReducer } from 'react-redux-loading-bar'

export default combineReducers({
  // ...your reducers
  loadingBar: loadingBarReducer
})

Then include the visual component in your top-level layout:

import { LoadingBar } from 'react-redux-loading-bar'

function AppShell() {
  return (
    <div>
      <LoadingBar />
      <MainRouter />
    </div>
  )
}

Finally, dispatch actions when a request starts/ends (examples below). This approach makes the indicator global and predictable.

Triggering the bar for async actions (thunk and saga patterns)

react-redux-loading-bar exposes action creators you can dispatch manually: typically showLoading() and hideLoading(), or the increment/decrement pattern for concurrent requests. For redux-thunk you wrap your async thunk; for redux-saga you dispatch around yield effects.

// thunk example
import { showLoading, hideLoading } from 'react-redux-loading-bar'

export function fetchData() {
  return async (dispatch) => {
    dispatch(showLoading())
    try {
      const data = await api.fetch()
      dispatch({ type: 'DATA_LOADED', payload: data })
    } finally {
      dispatch(hideLoading())
    }
  }
}

For concurrent requests, prefer the internal counter: if you call showLoading() multiple times, each hideLoading() decrements — the bar finishes only when the counter reaches zero. That avoids premature hiding if you fire several parallel fetches.

redux-saga pattern (conceptual): wrap long-running tasks in sagas that dispatch showLoading and hideLoading around yield call() effects or use a saga middleware helper to auto-dispatch on REQUEST/RESPONSE action pairs.

Customization: look, behavior and edge cases

The component accepts props to tweak style and behavior: change color, height, className or autoFinish timing depending on the implementation. If you need a custom CSS theme, target the component class or pass a style prop.

<LoadingBar style={{ backgroundColor: '#ff6600', height: '4px' }} />

Behavioral customizations include automatic progression, minimum display time and a delay-before-show to avoid flicker on very fast requests. Some implementations offer these props; otherwise implement a wrapper that dispatches show/hide with timers.

Edge cases to handle:

• Multiple parallel requests — use increment/decrement.
• Errors and early exits — ensure hide is in finally blocks.
• Navigation changes — decide if you want to cancel/finish the bar on route changes.

Example: full flow (thunk + UI)

Putting it together: reducer wired, LoadingBar rendered, thunk dispatching show/hide. This pattern works with Redux Toolkit too (dispatch function types are compatible).

// Simplified pattern
dispatch(showLoading());
try {
  await dispatch(apiThunk());
} finally {
  dispatch(hideLoading());
}

If you prefer less boilerplate, create a small helper or middleware that listens for REQUEST/SUCCESS/FAILURE action triplets and auto-dispatches show/hide. This reduces repetitive code and ensures uniform behavior across the app.

6. FAQ

How do I install and setup react-redux-loading-bar?

npm install react-redux-loading-bar (or yarn). Add loadingBarReducer to your root reducer, place <LoadingBar /> in the app shell and dispatch showLoading()/hideLoading() around async operations.

How do I trigger the loading bar for async actions?

Dispatch showLoading() before your request and hideLoading() after it finishes (use finally). For parallel requests, use multiple show/hide calls — the built-in counter keeps the bar visible until all requests complete.

How can I customize the loading bar?

Customize with props or CSS: change color, height or classes. For timing behavior (delay, auto-finish), implement a small wrapper that dispatches with timers or use middleware helpers that add min-duration and delay-before-show logic.

8. Implementation notes & best practices

Keep these small rules in your toolbelt:

• Always hide in finally blocks to avoid stuck bars on errors.
• Group related API calls where it makes UX sense; avoid flashing the bar for millisecond requests — consider a delay-before-show.
• Test concurrent flows and navigation transitions to ensure correct increments/decrements.
