Install: npm install @mantine/core@9.7.1 @mantine/hooks@9.7.1

Version and compatibility

Pinned Mantine Core 9.7.1 requires React and React DOM ^19.2.0 and matching @mantine/hooks@9.7.1, from the installed npm package's peerDependencies. Do not force it into React 18 or another incompatible version. Explain upgrade impact and agree on a plan with the project owner; do not hide conflicts with --force/--legacy-peer-deps. The native Provider enables theme.respectReducedMotion and uses forceColorScheme for light/dark.

Use case

Render responsive images with fallback support.

Native props used by this example

These props are extracted from the local typechecked JSX and grouped by their owning native component. This is not an exhaustive prop list; see pinned source signatures and inheritance below.

Component propExplanation
Image.wMantine width style prop.
Image.hMantine height style prop.
Image.srcImage source; provide loading/error behavior for real remote content.
Image.altImage alternative text.

Interaction and state checks

Current scenarios: Default. Check actual behavior after selecting supported disabled/error/read-only scenarios; components without those native states do not receive invented universal props. Verify keyboard focus and exits, then connect changed values through the native callback signature.

Business integration boundary

Demo content/state is local, without server persistence, authorization or fetching. A static display component is not a completed business workflow.

Host setup

Install pinned @mantine/core and @mantine/hooks, import @mantine/core/styles.css at the entry and use MantineProvider. The example's theme/variant are JGuang-authored host props, not universal native component APIs; forceColorScheme synchronizes the app theme. Native implementation source is a reading reference: use npm exports rather than copying internal engines. This batch covers Core, not dates/charts/forms extension packages. Detailed upstream prose remains English.

Runnable usage

import { useState } from 'react';
import * as M from '@mantine/core';
import '@mantine/core/styles.css';


function ComponentPreview({ variant = 'Default' }: { variant?: string }) {

return <M.Image w={240} h={120} src="data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='240' height='120'%3E%3Crect width='240' height='120' rx='12' fill='%232F67FF'/%3E%3C/svg%3E" alt="Blue color sample" />;
}
export default function Example({ variant = 'Default', theme = 'light' }: { variant?: string; theme?: 'light' | 'dark' }) {
return <M.MantineProvider forceColorScheme={theme} theme={{ respectReducedMotion: true }}><ComponentPreview variant={variant} /></M.MantineProvider>;
}

Preview states

Default

The example uses the native Mantine API. For supported input demos, change the local variant to Disabled, Invalid or Read only; these are example labels, not new component props. Keep the documented data, controlled values, stores and compound children when adapting the example.

Usage

Image is a wrapper for img with minimal styles. By default, the image will take 100% of the parent width. The image size can be controlled with w and h style props.

Image height

In most cases, you will need to set the image height to prevent layout jumps when the image is loading. You can do so with the h style props.

Image fit

By default the image has object-fit: cover style - it will resize to cover the parent element. To change this behavior, set w="auto" and fit="contain" props.

Fallback image

Set the fallbackSrc prop to display a fallback image when the image fails to load:

Usage with Next.js Image

The Image component is a polymorphic component, its root element can be changed with the component prop. You can use it with next/image and other similar components.

import NextImage from 'next/image';
import { Image } from '@mantine/core';
import myImage from './my-image.jpg';

function Demo() {
  return <Image component={NextImage} src={myImage} alt="My image" />;
}

Source-backed parameter reference

Implementation signatures and types are generated from the pinned local source. Optional props, native inherited types, union branches and never exclusions are preserved. A forwardRef implementation's ref is a React reference, not an additional business prop.

Native and external types

External types remain defined by React or native dependencies, not manually expanded into guessed props. The installed version's TypeScript definitions are authoritative.
