How can I handle error messages in Vue 3 with VeeValidate?

You can handle error messages in Vue 3 using VeeValidate by utilizing the useForm and useField composables. They allow you to manage form state and validation easily.

Can you show me a code example?

Sure! Here's a simple example:

import { useForm, useField } from 'vee-validate';

const { handleSubmit } = useForm();
const { value, errorMessage } = useField('email', 'required|email');

const onSubmit = handleSubmit((values) => {
  console.log(values);
});

How do I display the error messages in the template?

You can display error messages in your template like this:

<form @submit="onSubmit">
  <input v-model="value" type="email" />
  <span>{{ errorMessage }}</span>
  <button type="submit">Submit</button>
</form>

What if I want to customize the error messages?

You can customize error messages by passing a second argument to useField. For example:

const { value, errorMessage } = useField('email', {
  validate: value => !!value || 'Email is required',
});
