Usage

First of all, initialize form-bunch. Assume that you would like to use components of antd, the components should match two rules: 1. it has two fields —— value, onChange 2. the param(e) of onChange(e) => void must be corresponding to value. if one component has no value or onChange key, or it doesn't match form-bunch, you should replace them like following.

// index.tsx 
import { DatePicker, Input, Switch } from 'antd';

const extensions = {
  datePick: DatePicker,
  input: [
    Input,
    {
      // change the `e.target.value` to `value`
      // assume that original filed `onChange` is `onSelect`, 
      // then it should be `onChange: ['onSelect', 'e.target.value']`
      onChange: ['onChange', 'e.target.value'],
    },
  ],
  switch: [
    Switch,
    {
      // change the field `checked` to `value`
      value: 'checked'
    }
  ]
};

export type TExtensions = typeof extensions;

const MyFormBunch = formBunchInit<TExtensions>(extensions);

export default MyFormBunch;

And then, set style after verification failed in form-bunch-error-box className, then import it.

/* index.css */
.form-bunch-error-box .ant-input {
    border: 1px solid red;
    box-shadow: none
}

.form-bunch-error-box .ant-input:hover {
    border: 1px solid red;
}

.form-bunch-error-box .ant-input:active {
    border: 1px solid red;
}

// index.tsx
import './index.css'

...

export default MyFormBunch;

Finally, config form-bunch, and there are many apis for usage.

<MyFormBunch
  ref={formBunchRef}
  value={value}
  items={[
    {
      key: 'a',
      type: 'input',
    },
    {
      labelCol: '80px',
      offset: '40px',
      key: 'b',
      defaultValue: 'test',
      type: 'input',
      verify: (value) => value.length > 5,
    },
  ]}
  onChange={(value) => {
    setValue(value);
  }}
/>
