@formzk/mui

@formzk/mui was created to bridge the gap between headless form management and Material-UI's rich component library. While @formzk/core provides the foundation for flexible form logic, developers often need to invest additional effort to integrate UI components. @formzk/mui addresses this by offering a set of ready-to-use, pre-configured Material-UI components that work seamlessly with the core architecture. This reduces the overhead of setting up forms and ensures that developers can leverage the full potential of Material-UI with the powerful form handling capabilities of @formzk/core

Getting Started

@formzk/mui allows developer to seamlessly utilize both the native components from @formzk/core package and providing a robust toolkit for creating and managing forms with Material-UI's component library

To begin using @formzk/mui, ensure that you have @formzk/core set up in your project. If you need guidance on the initial setup, please refer to the @formzk/core documentation

Accessing Components

Native Components

With @formzk/mui package, you can still access the native components provided by @formzk/core without importing the core package separately. Just use the Formzk.Native namespace to access these components:

Namespace	Reference
Formzk.Native.Provider	Checkout
Formzk.Native.Form	Checkout
Formzk.Native.Input	Checkout
Formzk.Native.Submit	Checkout
Formzk.Native.Reset	Checkout
Formzk.Native.Errors	Checkout

Material-UI Components

To access the enhanced Material-UI components, use the Formzk.MUI namespace:

Namespace	Reference
Formzk.MUI.Provider	Checkout
Formzk.MUI.Form	Checkout
Formzk.MUI.Item	Checkout

Using Formzk.MUI.Form

Formzk.MUI.Form works similarly to Formzk.Native.Form or Formzk.Form but includes additional functionality for layout rendering. It allows developer to define the form layout using a config prop that accepts a multi-dimensional array. Each sub-array represents a row, and each object within a sub-array represents a column

Please refer the example below

import { Formzk } from '@formzk/mui';
import { yupResolver } from '@hookform/resolvers/yup';
import * as yup from 'yup';
import { Button } from '@mui/material';

type InputPayload = {
  email: string;
  password: string;
};

const schema = yup.object().shape({
  email: yup.string().required('Email is required').email('Invalid email address'),
  password: yup.string().required('Password is required').min(8, 'Minimum length is 8 characters'),
});

<Formzk.MUI.Form<InputPayload>
  name="login-form"
  options={{
    resolver: yupResolver(schema),
    defaultValues: {
      email: '[e-mail]',
      password: '',
    },
  }}
  onSubmit={(values) => {
    console.log('Formzk.Form submit ---->', values);
  }}
  config={[
    [
      {
        name: 'email',
        label: 'Email Address',
        component: 'TextField',
        disabled: false,
        props: {
          required: true,
          placeholder: 'Email Address',
        },
      },
      {
        name: 'password',
        label: 'Password',
        component: 'TextField',
        disabled: false,
        props: { type: 'password', placeholder: 'Password' },
      },
    ],
    [
      {
        // can do this to render custom component
        content: (
          <>
            <Formzk.Native.Submit render={(e) => <Button type="submit">Submit</Button>} />
            <Formzk.Native.Reset render={(e) => <Button onClick={e}>Reset</Button>} />
          </>
        ),
      },
    ],
  ]}
>
  {/* ANY CONTENT ADDED WILL SHOWS BELOW CONFIG */}
  <Formzk.Native.Submit render={(e) => <Button type="submit">Submit</Button>} />
  <Formzk.Native.Reset render={(e) => <Button onClick={e}>Reset</Button>} />
</Formzk.MUI.Form>;

To customize the width for columns, please use the layoutProps property

config={[
  [
    {
      name: 'email',
      label: 'Email Address',
      component: 'TextField',
      disabled: false,
      props: {
        required: true,
        placeholder: 'Email Address',
      },
      layoutProps: { // <-- this
        sm: 4,
        md: 4,
      },
    },
    {
      name: 'password',
      label: 'Password',
      component: 'TextField',
      disabled: false,
      props: { placeholder: 'Password' },
      layoutProps: { // <-- this
        sm: 8,
        md: 8,
      },
    },
  ],
]}

In this example, the email input field occupies 4 columns in both small (sm) and medium (md) screen sizes, while the password input field occupies 8 columns in the same screen sizes

Custom Layout

If you prefer to create your own layout without using the config props, you can structure your form in the traditional manner. Here’s an example:

import { Formzk } from '@formzk/mui';
import { yupResolver } from '@hookform/resolvers/yup';
import * as yup from 'yup';
import { Button } from '@mui/material';
import { useRef } from 'react';

const schema = yup.object().shape({
  email: yup.string().email().required(),
  password: yup.string().required(),
});

<Formzk.MUI.Form
  name="login-form"
  options={{
    resolver: yupResolver(schema),
    defaultValues: {
      email: '[e-mail]',
      password: '',
      rememberMe: false,
    },
  }}
  onSubmit={(values) => {
    console.log('Formzk.Form submit values ---->', JSON.stringify(values, null, 2));
  }}
>
  <Formzk.MUI.Item
    name="email"
    label="Email Address"
    component="TextField"
    props={{
      required: true,
      placeholder: 'Email Address',
    }}
  />
  <Formzk.MUI.Item
    name="password"
    label="Password"
    component="TextField"
    props={{
      type: 'password',
      placeholder: 'Password',
    }}
  />

  <Formzk.MUI.Item name="rememberMe" valueKey="checked" component="Checkbox" label="Remember me?" />

  <Formzk.Native.Reset
    render={(e) => (
      <Button onClick={e} variant="outlined">
        Reset
      </Button>
    )}
  />
  <Formzk.Native.Submit
    render={(e) => (
      <Button type="submit" variant="contained">
        Submit
      </Button>
    )}
  />
</Formzk.MUI.Form>;

In this example, the form components are arranged manually without relying on configuration properties. This approach allows you to freely design the form layout as per your requirements

Available Components

While developers can create their own input components, @formzk/mui comes with several built-in components designed to integrate seamlessly with the package. These components are tailored to provide a smooth and efficient form-building experience

Input Components

The following input components are included and optimized for use with @formzk/mui

• Checkbox: A standard checkbox input. (documentation)
• CheckboxGroup: A group of checkboxes for selecting multiple options (documentation)
• RadioGroup: A group of radio buttons for selecting one option from multiple choices (documentation)
• Switch: A toggle switch input for binary choices (documentation)

These components are designed to work effortlessly with @formzk/mui, ensuring consistency and ease of use. In the future, more input components will be added to expand the library's capabilities.

To consume the component, can register components at the entry point of your application (e.g: app.tsx) or any other preferred location

import { Checkbox, CheckboxGroup, CheckboxGroupProps, CheckboxProps, Formzk, RadioGroup, RadioGroupProps, Switch, SwitchProps } from '@formzk/mui';
import TextField, { TextFieldProps } from '@mui/material/TextField';

<Formzk.Native.Provider
  config={[
    {
      name: 'TextField',
      component: TextField,
      props: {
        fullWidth: true,
        variant: 'outlined',
        margin: 'normal',
      } as TextFieldProps,
    },
    {
      name: 'Checkbox',
      component: Checkbox,
      props: {} as CheckboxProps,
    },
    {
      name: 'Switch',
      component: Switch,
      props: {} as SwitchProps,
    },
    {
      name: 'RadioGroup',
      component: RadioGroup,
      props: {} as RadioGroupProps,
    },
    {
      name: 'CheckboxGroup',
      component: CheckboxGroup,
      props: {} as CheckboxGroupProps,
    },
  ]}
>
  {/* ... your component */}
</Formzk.Native.Provider>;

For module Augmentation

import { ComponentPropsMap as LibraryComponentPropsMap } from '@formzk/core';
import { CheckboxGroupProps, CheckboxProps, RadioGroupProps, SwitchProps } from '@formzk/mui';
import { TextFieldProps } from '@mui/material/TextField';

declare module '@formzk/core' {
  export interface ComponentPropsMap extends LibraryComponentPropsMap {
    TextField: TextFieldProps;
    Checkbox: CheckboxProps;
    Switch: SwitchProps;
    RadioGroup: RadioGroupProps;
    CheckboxGroup: CheckboxGroupProps;
  }
}

Other Components

In addition to input components, the package includes components focused on view rendering

• GridRenderView: A component for rendering views in a grid layout. (documentation)
• StackRenderView: A component for rendering views in a stack layout. (documentation)

These view rendering components help structure and organize your form layouts effectively, providing flexibility in design.
