rhf-mantine v2.0.4

rhf-mantine

A thin wrapper around the Mantine input components to use with react-hook-form.

Requires only a name prop added to the components and lets react-hook-form handle the rest, even automatically setting the error prop when react-hook-form triggers a validation error on the field.

Installation

npm install rhf-mantine
# or
yarn add rhf-mantine

Requires react-hook-form and @mantine/core as peer dependencies.

Install with peers:

npm install rhf-mantine react-hook-form @mantine/core
# or
yarn add rhf-mantine react-hook-form @mantine/core

If you indend to use the Date/Time inputs, you also need the dayjs and @mantine/dates as peers

npm install dayjs @mantine/dates
# or
yarn add dayjs @mantine/dates

Usage

Replace your import statments from @mantine/core with rhf-mantine.

Import FormProvider from react-hook-form and wrap around your form.

import { TextInput } from "rhf-mantine"
import { useForm, FormProvider } from "react-hook-form"

function MyComponent() {
  const formMethods = useForm()
  return (
    <FormProvider {...formMethods}>
      <TextInput
        name="myInput" // required
        rules={{ required: "This field is required" }}
        label="My Input"
        placeholder="Enter something"
      />
    </FormProvider>
  )
}

Most, but not all Mantine input components are supported. PRs welcome!

TypeScript Support

If you type your form values, you can pass the type to the components to get autocomplete suggestions on the required name prop

You can automatically infer the form types and avoid passing it everywhere if you use the createFormProvider method exposed by this package.

import { createFormProvider } from "rhf-mantine"
import { useForm, SubmitHandler } from "react-hook-form"

type FormValues = { name: string }

// create a Form Provider component with the types embedded
// be sure to do this OUTSIDE of your page/component to avoid re-renders
const Form = createFormProvider<FormValues>()

function MyComponent() {
  const form = useForm<FormValues>()

  const onSubmit: SubmitHandler<FormValues> = (data) => console.log(data)

  return (
    <Form {...form} onSubmit={onSubmit}>
      <Form.TextInput
        name="name"  {/* type is inferred from FormValues */}
        rules={{ required: "This field is required" }}
        label="My name"
      />
    </Form>
  )
}
