How can I validate multiple file uploads in Vue?

How can I validate multiple file uploads in Vue?

You can use the v-model directive to bind your file input to a data property and then validate the files in a method.

What kind of validations can I perform on the files?

You can check for file types, sizes, and even the number of files uploaded. For example, you can restrict uploads to images only.

Can you show me a code example for that?

Sure! Here's a simple example:

methods: {
  validateFiles(event) {
    const files = event.target.files;
    for (let file of files) {
      if (file.size > 2000000) { // 2MB limit
        alert('File is too large!');
      }
      if (!file.type.startsWith('image/')) {
        alert('Only image files are allowed!');
      }
    }
  }
}

You can call this method on the file input's change event.

What if I want to show error messages on the UI instead of alerts?

You can create an array to store error messages and display them in your template. Update the array in your validation method.
