Editor to share with you vue how to deal with errors and warnings, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

A better way to deal with errors (and warnings)

You can provide custom handlers for errors and warnings in Vue:

/ Vue 3const app = createApp (App); app.config.errorHandler = (err) = > {alert (err);}; / / Vue 2Vue.config.errorHandler = (err) = > {alert (err);}

Error tracking services such as Bugsnag and Rollbar are hooked into these handlers to log errors, but you can also use them to handle errors more elegantly for a better user experience.

For example, if the error is not handled, the application not only crashes, but can also display a full-page error screen and let the user refresh or try something else.

In Vue 3, error handlers are only available for templates and observers, but Vue 2 error handlers can capture almost everything. The warning handlers in both versions are for development only.
