How can I handle file upload errors in Vue 3?

In Vue 3, you can handle file upload errors by using the try-catch block in your upload method. You can also check the response from the server for specific error messages.

Can you show me a code example?

Sure! Here's a simple example:

async uploadFile(file) {
  try {
    const response = await this.$http.post('/upload', file);
    // Handle success
  } catch (error) {
    // Handle error
    console.error('Upload failed:', error);
  }
}

What kind of errors should I expect?

You might encounter errors like file size limits, unsupported file types, or network issues. Always check the server response for detailed error messages.

How can I display these errors to the user?

You can use a reactive property in your Vue component to store the error message and display it in your template using a conditional rendering.
