How can I implement user input validation in Vue.js?

You can use the built-in validation features of Vue.js or libraries like Vuelidate or VeeValidate. What specific input do you want to validate?

I want to validate a form with an email and password.

For email, you can use a regex pattern to check its format. For password, you might want to check for length and special characters. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

data() {
  return {
    email: '',
    password: '',
    emailError: '',
    passwordError: ''
  };
},
methods: {
  validate() {
    this.emailError = this.validateEmail(this.email) ? '' : 'Invalid email';
    this.passwordError = this.validatePassword(this.password) ? '' : 'Password must be at least 6 characters';
  },
  validateEmail(email) {
    const re = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
    return re.test(email);
  },
  validatePassword(password) {
    return password.length >= 6;
  }
}

This will validate the email format and ensure the password is at least 6 characters long.
