Usage

JsonInput is based on Textarea component, it includes json validation logic and option to format input value on blur:

<JsonInput
  label="Your package.json"
  placeholder="Textarea will autosize to fit the content"
  validationError="Invalid json"
  formatOnBlur
  autosize
  minRows={4}
/>

Controlled

import { useState } from 'react';
import { JsonInput } from '@mantine/core';


function Demo() {
  const [value, setValue] = useState('');
  return <JsonInput value={value} onChange={setValue} />;
}

Input props

Component supports all props from Input and InputWrapper components:

Radius
xs
sm
md
lg
xl
Size
xs
sm
md
lg
xl
<JsonInput
  placeholder="Your package.json"
  label="Your package.json"
  required
/>

Get input ref

import { useRef } from 'react';
import { JsonInput } from '@mantine/core';


function Demo() {
  const ref = useRef(null);
  return <JsonInput ref={ref} />;
}

Accessibility

Provide aria-label in case you use component without label for screen reader support:

<JsonInput /> // -> not ok, textarea is not labeled
<JsonInput label="package.json" /> // -> ok, textarea and label is connected
<JsonInput aria-label="package.json" /> // -> ok, label is not visible but will be announced by screen reader
