How do I connect with the global error handling in Vue?

Within my Vue2 application, I am seeking a method to capture global Vue errors and transmit them to a logging or monitoring service such as Sentry.

After attempting to overwrite the global error handler of Vue, I noticed that console logs were no longer appearing. Is it feasible to attach to the global error handler rather than replacing it entirely?

const plugin: PluginObject<never> = {
    install(Vue: typeof _Vue): void {
        Vue.config.errorHandler = (err, vm, info) => {
            // integrating with Sentry        
        }
    })
}

typescript vue.js vuejs2

To ensure you can capture and log errors while still preserving the default error handling process, it is essential to store a reference to the original error handler and then invoke it within your custom error handler function. This way, you can effectively transfer errors to your designated logging or monitoring service.

const plugin: PluginObject<never> = {
install(Vue: typeof _Vue): void {
    // Store the original error handler
    const originalErrorHandler = Vue.config.errorHandler;

    Vue.config.errorHandler = (err, vm, info) => {
        // Your Sentry or other logging/monitoring code
        // ...

        // Call the original error handler, if it exists
        if (originalErrorHandler) {
            originalErrorHandler.call(this, err, vm, info);
        } else {
            // If there wasn't an original error handler, you can log the error to the console
            console.error(err);
        }
    };
}

};
