We're excited to announce the release of Cerberus v0.21! This update brings powerful new components, improved styling capabilities, and several important fixes to make your development experience even smoother.

Our mission continues: make Cerberus easier to use, extend, and customize for every project.

New Components

NumberInput

Introducing the new NumberInput component, designed for seamless numeric input with built-in accessibility and customization. Easily control min/max values, step increments, and styling using the familiar Cerberus API.

1
import { Field } from '@cerberus/react/field';
2
import { NumberInput } from '@cerberus/react/number-input';
3
import { Box } from 'styled-system/jsx';
4

5
function NumberInputDemo() {
6
  return (
7
    <Box w="1/2">
8
      <Field label="How many?" helperText="Choose your quantity.">
9
        <NumberInput />
10
      </Field>
11
    </Box>
12
  )
13
}

PinInput

The new PinInput component makes it simple to build secure PIN or code entry forms. It supports custom lengths, masking, and full style customization.

1
import { PinInput, Field } from '@cerberus-design/react'
2
import { HStack } from 'styled-system/jsx'
3

4
export function StaticPreview() {
5
  return (
6
    <HStack w="1/2">
7
      <Field label="Enter PIN">
8
        <PinInput />
9
      </Field>
10
    </HStack>
11
  )
12
}

Notifications - Subtle Variant

Cerberus Notifications now support a “subtle” variant for less intrusive alerts. Use it for gentle feedback or status updates that blend into your UI.

Just add the -subtle suffix to the toast type.

1
import { toaster } from '@cerberus/react/toaster'
2

3
toaster.create({
4
  type: 'info-subtle',
5
  title: 'Update Available',
6
  description: 'A new version of the app is available',
7
  action: {
8
    label: 'Refresh',
9
    onClick: () => {
10
      window.location.reload()
11
    }
12
  }
13
})

Factory - Universal Style Props

All Cerberus components now inherit style props via the Factory system. This means you can use any CSS style property or the css prop on any component. Customizing appearance is now faster and more consistent across your app.

This applies to all Cerberus APIs (including factory components).

1
import { Button } from '@cerberus/react/button';
2

3
function CustomButtonPreview() {
4
  return (
5
    <Button
6
      bgColor="danger.bg.initial"
7
      color="danger.text.initial"
8
      rounded="md"
9
      transform="skew(-10deg)"
10
      _hover={{
11
        bgColor: 'black',
12
        color: 'yellow',
13
      }}
14
      css={{
15
        '&:is([data-custom=selector])': {
16
          bgColor: 'blue.500',
17
          color: 'white',
18
        }
19
      }}
20
    >
21
      Cerberus Forever
22
    </Button>
23
  )
24
}
