Sanity UI

When you're creating new tools and custom inputs, it's important for your editor experience to make sure your customizations match the overall design of the studio. To create this consistency, you can use the Sanity UI component library to create custom experiences without creating custom designs or adding custom CSS.

The Sanity UI package comes bundled for most studio usage, but if you're creating a plugin or tool, you'll want to install the package via NPM.

npm install @sanity/ui

From there, you can import the various components into your custom inputs, tools, or widgets. For example, if you wish to apply a tooltip to a string input, you can create a custom input that uses the Stack, Box, and TextInput design primitives to create one with all the design elements of your studio built right in.

// /components/MyCustomStringInput.jsx
import React, {useCallback} from 'react'
import {Stack, Text, TextInput} from '@sanity/ui'
import {set, unset} from 'sanity'

export const MyCustomStringInput = (props) => {
  const {elementProps, onChange, value = ''} = props

  const handleChange = useCallback((event) => {
    const nextValue = event.currentTarget.value
    onChange(nextValue ? set(nextValue) : unset())
	}, [onChange])

  return (
    <Stack space={2}>
      <TextInput
        {...elementProps}
        onChange={handleChange}
        value={value}
      />
      <Text>Characters: {value.length}</Text>
    </Stack>
  )
}

See this guide on creating custom inputs and tools with Sanity UI.

Sanity UI comes with a full set of UI primitives that can be mixed, matched, and composed into many different design patterns. The full list of components can be found in the official Sanity UI documentation. To get a better feel for creating design patterns, you can also experiment with all the components in this interactive component playground.
