A React Component - Progress Indicator
This repo contains a component for displaying a "Progress Indicator" with backdrop & spinner icon. Use during async loading operations such as making a request or performing calculations. Supports progress indication of parallel separate, but related, async events, this component will keep track of a count of active events.
See Demo: http://jbacon.github.io/react-component-progress-indicator
Source: ./src/App.js
Usage
import ProgressIndicatorProvider, { ProgressIndicatorController } from "@jbacon47/react-component-progress-indicator"
function Example() {
const handleSubmit = (loader) => (event) => {
event.preventDefault();
loader.signalLoading();
// Replace timeout with app logic
window.setTimeout(() => {
loader.signalLoaded();
}, 2000);
}
return (
<ProgressIndicatorProvider>
{/* .... */}
<ProgressIndicatorController>
{loader => (
{/* .... */}
<form onSubmit={handleSubmit(loader)}>
<input type="submit" value="Try Me" />
</form>
)}
</ProgressIndicatorController>
{/* .... */}
</ProgressIndicatorProvider>
)
}
Exports:
ProcessIndicatorProvider
- Wraps content with spinner backdropwithProgressIndicator
- Wraps child component with controlsuseProgressIndicator
- Wraps child component with controlsProgressIndicatorController
- The controller context
Available Controls:
context.signalLoading()
- increments number of active loading events (> zero, show spinner)context.signalLoaded()
- decrements number of active loading events (== zero, hide spinner)- If making many parallel async/loading requests, the provider keeps track of the current count
Development
I built this because I did not see any out-of-the-box solutions for progress indicators that support multi/parallel async events. It was also a great learning experience for creating, publish, and deploying standalone components to NPM. Most spinners are simple and require managing properties and visibility state on a single component.
Run Demo
npm install && npm start

Getting Started with Create React App
This project was bootstrapped with Create React App.
Available Scripts
In the project directory, you can run:
npm start
Runs the app in the development mode.\ Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.\ You will also see any lint errors in the console.
npm test
Launches the test runner in the interactive watch mode.\ See the section about running tests for more information.
npm run build
Builds the app for production to the build
folder.\
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.\ Your app is ready to be deployed!
See the section about deployment for more information.
npm run eject
Note: this is a one-way operation. Once you eject
, you can’t go back!
If you aren’t satisfied with the build tool and configuration choices, you can eject
at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject
will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
You don’t have to ever use eject
. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
