Button

A simple, sizable button.

Features

  • Accepts size prop that works on all styles.

  • Can inverse theme with themeInverse.

  • Place an icon before or after.

Usage

import { Button } from 'tamagui'
export default () => <Button>Lorem ipsum</Button>

Sizing

Sizing buttons provides a unique challenge especially for a compiler, because you need to adjust many different properties - not just on the outer frame, but on the text wrapped inside. Tamagui supports adjusting the padding, border radius, font size and icons sizes all in one with the size prop.

import { Button } from 'tamagui'
export default () => <Button size="$6">Lorem ipsum</Button>

Given your theme defines a size 6, the button will adjust all of the properties appropriately. You can also pass a plain number to get an arbitrary size.

Icon Theming

You can pass icons as either elements or components. If passing components, Tamagui will automatically pass the size and color prop to them based on your theme.

You can use the source of Button itself  to see in more detail what variants you can override, and how we use this pattern internally to create our Button component.

Button props

Buttons extend Stack views inheriting all the Tamagui standard props, plus:

Props

  • size

    string | tokens.size

    Set a size, number or one of the size token values.

  • theme

    string

    Apply a theme just to the button and it's children

  • themeInverse

    boolean

    Helpful for "flipping" any theme between dark and light (including flipping a sub themes defined as [subtheme]-[dark/light]

  • noTextWrap

    boolean

    If true, Button won't wrap content with a Text element.

  • icon

    JSX.Element

    Pass any React element, appears before the text.

  • iconAfter

    JSX.Element

    Pass any React element, appears after the text.

  • scaleIcon

    number

    Scale the icon more than usual by this number.

  • scaleSpace

    number

    Scale the spacing more than usual by this number.

  • spaceFlex

    boolean

    Makes all space elements have a flex.

  • color

    SizableTextProps['color']

    Passes "color" down to the inner text component

  • fontWeight

    SizableTextProps['fontWeight']

    Passes "fontWeight" down to the inner text component

  • letterSpacing

    SizableTextProps['letterSpacing']

    Passes "letterSpacing" down to the inner text component

  • textAlign

    SizableTextProps['textAlign']

    Passes "textAlign" down to the inner text component

  • circular

    boolean

    Forces a circular button.

  • Advanced Button Customization

    Tamagui <Button /> is a React functional component that renders multiple styled() components, not a single Tamagui styled() element itself. This means you can't wrap it with styled(Button) to change variants.

    We'd like to support this feature eventually , but until then we've exported a useButton hook, alongside ButtonFrame, ButtonText, and buttonStaticConfig that make it simple to create your own Button.

    Your custom Button.tsx in your design system would look something like this:

    import { forwardRef } from 'React'
    import { styled, themeable, ButtonFrame, ButtonText, useButton, buttonStaticConfig } from 'tamagui'
    const CustomButtonFrame = styled(ButtonFrame, {
    // ... customize your button frame base styles
    variants: {
    // ... customize your button frame variants
    } as const
    })
    const ButtonComponent = forwardRef<TamaguiElement, ButtonProps>(function Button(props, ref) {
    const { props: buttonProps } = useButton(
    props,
    // optionally customize the inner Text
    { Text: ButtonText }
    )
    return <CustomButtonFrame {...buttonProps} ref={ref} />
    })
    // Wrapping in extractable() lets the compiler run build-time optimizations on your custom Button
    // Wrapping in themable means `<Button theme="" />` properly updates theme before useButton needs it
    export const Button = ButtonFrame.extractable(themeable(ButtonComponent), buttonStaticConfig)
