How do I handle errors in async functions in Vue.js?

In Vue.js, you can handle errors in async functions using try-catch blocks. Here's a simple example:

async fetchData() {
  try {
    const response = await axios.get('/api/data');
    this.data = response.data;
  } catch (error) {
    console.error('Error fetching data:', error);
    this.errorMessage = 'Failed to load data.';
  }
}

What if I want to show a user-friendly message instead of logging the error?

You can set a data property to hold the user-friendly message and display it in your template. For example:

this.errorMessage = 'Oops! Something went wrong. Please try again later.';

Can I use Vue's errorHandler for global error handling?

Yes, you can use Vue's global errorHandler to catch errors from all components. You can define it like this:

Vue.config.errorHandler = (err, vm, info) => {
  console.error('Global error handler:', err);
};

Are there any libraries that can help with error handling in Vue?

Yes, libraries like Sentry or Rollbar can help you track and report errors in your Vue applications.
