Usage

In your component file:

import { ref } from '@vue/composition-api';
import { useForm, useField } from 'vue-use-form';

export default {
  setup() {
    const fname = ref('');
    const { form, submit } = useForm({
      onSubmit () {
        console.log('Submitting!', {
          fname: fname.value
        });
      }
    });

    const { errors } = useField('firstName', {
      rules: 'required',
      value: fname,
      form
    });

    return { fname, errors, submit };
  }
};

In your Template:

<form @submit.prevent="submit">
  <input v-model="fname">
  <span>{{ errors[0] }}</span>
  <button>Submit</button>
</form>

API

useForm(object)

The useForm function accepts options to configure the form.

const { form, submit } = useForm({
  onSubmit () {
    // this will only run when the form is valid.
    // send to server!
  }
});

It returns an object containing two properties:

form: A form controller object, which can be used with useField to associate fields in the same form.
submit: A safe form submit handler to bind to your submission handler, it will validate all the fields before it runs the given onSubmit handler.

useField(string, string | object)

The useField function accepts a string which is the input name, and options to configure the field:

const field = useField('firstName', {
  rules: 'required', // vee-validate style rules, can be a Ref<string>.
  value: fname, // the initial field value, optional.
  form // a form controller object returned from "useForm", used to group fields. optional.
});

It returns the following members:

Prop	Type	Description
flags	`ValidationFlags`	Object containing vee-validate flags for that field.
errors	`string[]`	list of validation errors
validate	`() => ValidationResult`	Triggers validation for the field.
reset	`() => void`	Resets validation state for the field.
onInput	`() => void`	Updates some flags when the user inputs, you should bind it to the element.
onBlur	`() => void`	Updates some flags when the user focuses the field, you should bind it to the element.
value	`Ref<string>`	A default ref in-case you didn't pass the initial value
