⚛️ React Error Guard Component ⚛️

Setup your consuming project

Firs install the package with yarn add react-error-guard (or npm i --save). Then you can consume the component like bellow.

const MyReactContainer = ({ children }) => {
  let ErrorBoundaryContainer = null;

  if (process.env.NODE_ENV !== 'production') {
    ErrorBoundaryContainer = require('react-error-guard').DeveloperErrorBoundary;
  } else {
    ErrorBoundaryContainer = require('react-error-guard').ProductionErrorBoundary;
  }

  return <ErrorBoundaryContainer>{children}</ErrorBoundaryContainer>;
}

ℹ️ Notice: This component right now is only compatible with React 16. But there are plans to support React 15 but much more limited version, unstable_handleError.

<DeveloperErrorBoundary />

It is meant to be used as a drop-in helper on development environments. It is a declarative component, abstracted from the react-error-overlay. The error screen from the development server from create-react-app.

DeveloperErrorBoundary preview

<ProductionErrorBoundary />

It is meant to be used on production environments, as a helper to provide a fallback error screen and also automated reports to your preferred tool via the dispatchErrorReporting prop.

Customizing <ProductionErrorBoundary />

ProductionErrorBoundary is highly customisable through its props.

Default ProductionErrorBoundary preview (with no dispatchErrorReporting provided)

<ProductionErrorBoundary>
  {children}
</ProductionErrorBoundary>

The code above will produce the following default error message component render:

Default ProductionErrorBoundary preview (with dispatchErrorReporting provided)

<ProductionErrorBoundary dispatchErrorReporting={dispatchErrorReporting}>
  {children}
</ProductionErrorBoundary>

The code above will produce the following default error message component render:

You can even replace the default error message by passing errorMessageComponent prop.

const ErrorMessageComponent = (
  <div className="error-message">
    <h1>🚨 Whoopsie, we crashed 🚨</h1>
    <p>Don't worry, an automated error report has been sent to our team of cats to handle this.</p>
  </div>
);

const IconClose = <span>❌</span>;

const dispatchErrorReporting = ({ error, info }) => {
  Raven.captureException(error, {
    extra: {
      ...info, reactVersion: React.version
    },
    tags: { version, reactVersion: React.version }
  });
}

const MyReactContainer = ({ children }) => (
  <ProductionErrorBoundary
    errorMessageComponent={ErrorMessageComponent}
    closeIcon={<IconClose />}
    dispatchErrorReporting={dispatchErrorReporting}
  >
    {children}
  </ProductionErrorBoundary>
)

▶️ The example above uses raven-js but any reporting tool can be used.

🌟 This project started, and still is, an abstraction taken from the amazing works of the create-react-app team.
