Chaos Engineering for your React applications.
React Chaos is currently a higher order component that will randomly throw Errors in the component it wraps. The likelihood for the error to throw is based on a level you set when you wrap a component.
Blog post: Announcing React Chaos Demo: https://react-chaos.netlify.com/
- This is currently WIP and a proof-of-concept.
- There is nothing in place to help ensure good performance practices. Use at your own risk.
npm i --save-dev react-chaosFirst, import the Chaos:
import withChaos from 'react-chaos';Wrap any component with the Chaos:
const ComponentToWrap = () => <p>I may have chaos.</p>;
const ComponentWithChaos = withChaos(ComponentToWrap);You can optionally set a Chaos level between 1 and 10 (the higher the number, the more Chaos 😈) as well as a custom error message:
const ComponentWithChaos = withChaos(ComponentToWrap);
const ComponentWithChaos = withChaos(
ComponentToWrap,
10,
'This error message will almost certainly be shown since we are at Chaos level 10.'
);Note: The default Chaos level is 5.
By default, React Chaos will not run in production. If you want to override this by passing in true as a 4th parameter like this:
const ComponentWithChaos2 = withChaos(
ComponentWillHaveChaos2,
3,
'a custom error message, level 3',
true
);- Because simple UI errors shouldn't bring down your app.
- This library can help expose areas of your component tree that don't handle errors very gracefully. Used in conjunction with Error Boundaries, this can be a powerful tool to improve the resiliency of your UI components.
Chaos Engineering is the practice of experimenting with entropy on a software system to test its resiliency. You can read more about it here.
