How can I implement forms and validation in Vue.js?

How can I implement forms and validation in Vue.js?

You can use Vue's built-in directives for forms and libraries like Vuelidate or VeeValidate for validation.

Can you show me a simple example of a form with validation?

Sure! Here's a basic example:

<template>
  <form @submit.prevent="submitForm">
    <input v-model="name" placeholder="Enter your name" required />
    <span v-if="!isValidName">Name is required.</span>
    <button type="submit">Submit</button>
  </form>
</template>

<script>
export default {
  data() {
    return {
      name: '',
    };
  },
  computed: {
    isValidName() {
      return this.name.trim() !== '';
    },
  },
  methods: {
    submitForm() {
      if (this.isValidName) {
        alert(`Hello, ${this.name}!`);
      }
    },
  },
};
</script>

What libraries do you recommend for more complex validation?

For complex validation, I recommend using VeeValidate or Vuelidate. They offer extensive features and flexibility.

How do I handle form submission errors?

You can handle submission errors by using a try-catch block in your submit method and displaying error messages accordingly.
