Tokens
Managing design decisions in your app using tokens.
Overview
Design tokens are the platform-agnostic way to manage design decisions in your application or website. It is a collection of attributes that describe any fundamental/atomic visual style. Each attribute is a key-value pair.
A design token consists of the following properties:
value
: The value of the token. This can be any valid CSS value.description
: An optional description of what the token can be used for.
Defining Tokens
Tokens are defined in the under the theme
key in your system config.
theme.ts
import { createSystem, defineConfig } from "@chakra-ui/react"
const config = defineConfig({
theme: {
tokens: {
colors: {
primary: { value: "#0FEE0F" },
secondary: { value: "#EE0F0F" },
},
fonts: {
body: { value: "system-ui, sans-serif" },
},
},
},
})
export const system = createSystem(config)
Token values need to be nested in an object with a value
key. This is to
allow for additional properties like description
and more in the future.
Using Tokens
After defining tokens, we recommend using the Chakra CLI to generate theme typings for your tokens.
npx @chakra-ui/cli typegen ./src/theme.ts
This will provide autocompletion for your tokens in your editor.
<Box color="primary" fontFamily="body">
Hello World
</Box>
Token Nesting
Tokens can be nested to create a hierarchy of tokens. This is useful when you want to group related tokens together.
DEFAULT
key to define the default value of a nested token.theme.ts
import { defineConfig } from "@chakra-ui/react"
const config = defineConfig({
theme: {
tokens: {
colors: {
red: {
DEFAULT: { value: "#EE0F0F" },
100: { value: "#EE0F0F" },
},
},
},
},
})
export default createSystem(config)
<Box
// 👇🏻 This will use the `DEFAULT` value
bg="red"
color="red.100"
>
Hello World
</Box>
