--- title: Recipes description: Learn how to customize recipes and slot recipes in Chakra UI --- :::info Please read the [overview](/docs/theming/customization/overview) first to learn how to properly customize the styling engine, and get type safety. ::: ## Recipes ### Extending variants Use the `defineRecipe` function to define a recipe override. Here's an example of extending the `Button` to add a new `xl` size ```tsx title="theme.ts" const buttonRecipe = defineRecipe({ variants: { size: { xl: { fontSize: "lg", px: 6, py: 3, }, }, }, }) const customConfig = defineConfig({ theme: { recipes: { button: buttonRecipe, }, }, }) export const system = createSystem(defaultConfig, customConfig) ``` Then you can use the new size variant in your components. ```tsx ``` ### Adding new variant Use the `defineRecipe` function to define a new recipe variant. Here's an example of defining a boolean variant called `raised`. ```tsx title="theme.ts" const buttonRecipe = defineRecipe({ variants: { raised: { true: { boxShadow: "md", }, }, }, }) const customConfig = defineConfig({ theme: { recipes: { button: buttonRecipe, }, }, }) export const system = createSystem(defaultConfig, customConfig) ``` Then you can use the new variant in your components. ```tsx ``` ### Custom recipe Use the `defineRecipe` function to define a custom recipe all together. Here's an example of defining a custom recipe called `Title` ```tsx title="theme.ts" const titleRecipe = defineRecipe({ baseStyle: { fontWeight: "bold", letterSpacing: "tight", }, variants: { size: { md: { fontSize: "xl" }, lg: { fontSize: "2xl" }, }, }, }) const customConfig = defineConfig({ theme: { recipes: { title: titleRecipe, }, }, }) export const system = createSystem(defaultConfig, customConfig) ``` Then, use the new recipe to create a components ```tsx const Title = (props) => { const recipe = useRecipe({ key: "title" }) const styles = recipe({ size: "lg" }) return } ``` ## Slot Recipes To effectively override an existing slot recipe, we recommend connecting to its anatomy. Slot recipes are added to the `theme.slotRecipes` object. ### Extending variants Here's an example of how to extend the `Alert` slot recipe to create an `xl` size. ```tsx title="theme.ts" import { alertAnatomy } from "@chakra-ui/react/anatomy" const alertSlotRecipe = defineSlotRecipe({ slots: alertAnatomy.keys(), variants: { size: { xl: { root: { fontSize: "lg", px: 6, py: 3, }, }, }, }, }) const customConfig = defineConfig({ theme: { slotRecipes: { alert: alertSlotRecipe, }, }, }) export const system = createSystem(defaultConfig, customConfig) ``` Then you can use the new size variant in your components. ```tsx /size="xl"/ ``` ### Adding new variant Here's an example of how to extend the `Alert` slot recipe to add a new variant called `shape`. ```tsx title="theme.ts" import { alertAnatomy } from "@chakra-ui/react/anatomy" const alertSlotRecipe = defineSlotRecipe({ slots: alertAnatomy.keys(), variants: { shape: { rounded: { root: { borderRadius: "full" }, }, }, }, }) const customConfig = defineConfig({ theme: { slotRecipes: { alert: alertSlotRecipe, }, }, }) export const system = createSystem(defaultConfig, customConfig) ``` Then you can use the new variant in your components. ```tsx /shape="rounded"/ ``` ### Custom recipe Here's an example of how to define a custom slot recipe called `Navbar`. ```tsx title="theme.ts" const navbarSlotRecipe = defineSlotRecipe({ slots: ["root", "badge", "icon"], base: { root: { bg: "blue.500", color: "white", px: 4, py: 2, }, badge: { borderRadius: "full", px: 2, py: 1, }, }, }) const customConfig = defineConfig({ theme: { slotRecipes: { navbar: navbarSlotRecipe, }, }, }) export const system = createSystem(defaultConfig, customConfig) ``` Then you can use the new recipe to create a components ```tsx const Navbar = (props) => { const recipe = useSlotRecipe({ key: "navbar" }) const styles = recipe() return ( {props.children} ) } ```
