Default props

You can define default props for every Mantine component by setting theme.components on MantineProvider:

import { MantineProvider, Group, Button, Switch } from '@mantine/core';


function Demo() {
  return (
    <>
      <MantineProvider
        theme={{
          components: {
            Button: {
              defaultProps: {
                size: 'xs',
                color: 'cyan',
              },
            },


            Switch: {
              defaultProps: {
                size: 'xs',
                onLabel: 'ON',
                offLabel: 'OFF',
              },
            },
          },
        }}
      >
        <Group position="center">
          <Button>Within provider</Button>
          <Switch label="Within provider" />
        </Group>
      </MantineProvider>


      <Group position="center" mt="md">
        <Button>Outside of provider</Button>
        <Switch label="Outside of provider" />
      </Group>
    </>
  );
}

Overriding default props

Default props defined on MantineProvider will be overridden with props that you set on component itself:

import { MantineProvider, Button } from '@mantine/core';


function Demo() {
  return (
    <MantineProvider
      theme={{
        components: {
          Button: {
            defaultProps: { color: 'red' },
          },
        },
      }}
    >
      <Button>Red color, defined with defaultProps</Button>
      <Button color="cyan">Cyan color, overridden by prop</Button>
    </MantineProvider>
  );
}

Usage with TypeScript

MantineProvider uses Record<string, any> type for default props types to improve TypeScript performance. If you need more strict type checks or want to have IDE autocomplete, you should define default props separately:

import { MantineProvider, ButtonProps, SwitchProps } from '@mantine/core';


const ButtonDefaultProps: Partial<ButtonProps> = {
  size: 'xs',
  color: 'cyan',
};


const SwitchDefaultProps: Partial<SwitchProps> = {
  size: 'xs',
  onLabel: 'ON',
  offLabel: 'OFF',
};


function Demo() {
  return (
    <MantineProvider
      theme={{
        components: {
          Button: { defaultProps: ButtonDefaultProps },
          Switch: { defaultProps: SwitchDefaultProps },
        },
      }}
    >
      <App />
    </MantineProvider>
  );
}
