canopy-react-error-boundary

A higher order component / decorator for creating error boundaries in React code at Canopy. The decorator implements componentDidCatch and will render a modal explaining to the user that a Canopy feature is having problems.

Note that using the decorator will also, by default, put your react component tree and single-spa application into React Strict Mode. You can disable this behavior if you so wish by setting the noStrictMode opt.

When to use this

All single-spa applications should implement componentDidCatch in the root component. So this decorator should at least be applied to the top-level component for each single-spa application.

In addition to the top level component, you can add error boundaries wherever you'd like.

Usage

yarn add canopy-react-error-boundary

import ErrorBoundary from 'canopy-react-error-boundary';

@ErrorBoundary({featureName: 'calendar'})
class Root extends React.Component {
}

Opts

• featureName (required): A string name for the feature. This is shown to the user when componentDidCatch is called, so it should be user friendly.
• noStrictMode (optional): A boolean that defaults to false. When true, this turns of react strict mode. Note that canopy-react-error-boundary is compatible with react@<=15 and will not try to use React.StrictMode if it is not available.
