Rule Definition
An empty catch block defeats the purpose of exceptions. When an exception occurs, nothing happens and the program fails for an unknown reason. The application can be in an unknown state that will affect subsequent processing. Since the reason for the issue (the exception type and potential embedded message) are ignored, it will require more time to fix the issue.

Remediation
The exception must be handled correctly according to its type.

Violation Code Sample

"use strict";
class MyComponentWithErrorBoundary extends React.Component {
    constructor(props) {
        super(props);
        this.state = { hasError: false };
    }
    componentDidCatch(error, info) {
        // empty
    }
    render() {
        if (this.state.hasError) {
            // You can render any custom fallback UI
            return '<h1>Something went wrong.</h1>';
        }
        return this.props.children;
    }
}

Fixed Code Sample

"use strict";
class MyComponentWithErrorBoundary extends React.Component {
    constructor(props) {
        super(props);
        this.state = { hasError: false };
    }
    componentDidCatch(error, info) {
        // Display fallback UI
        this.setState({ hasError: true });
        // You can also log the error to an error reporting service
        logErrorToMyService(error, info);
    }
    render() {
        if (this.state.hasError) {
            // You can render any custom fallback UI
            return '<h1>Something went wrong.</h1>';
        }
        return this.props.children;
    }
}
