Dynamically resolve styleName in RN with support for multi-class selectors (for easier modifiers)
Transform JSX styleName
property to style
property in react-native. The styleName
attribute and syntax are based on babel-plugin-react-css-modules.
This is the fork of https://github.com/kristerkari/babel-plugin-react-native-stylename-to-style
The differences are:
import classnames from 'classnames'
function Button ({
variant, // [string] 'primary' | 'secondary'
dark, // [bool]
disabled // [bool]
}) {
return (
<Text
styleName={classnames('button', [variant, { dark, disabled }])}
>CLICK ME</Text>
)
}
.button
background-color: blue
&.primary
color: #ff0000
&.disabled
color: rgba(#ff0000, 0.5)
&.secondary
color: #00ff00
&.disabled
color: rgba(#00ff00, 0.5)
&.disabled
color: #777
.dark
&.button
background-color: purple
&.primary
color: white
&.disabled
color: #ddd
&.disabled
color: #eee
And what's important is that selectors` specificity is properly emulated. For example:
Styles for .button.primary.disabled
(specificity 30) will override styles of .button.disabled
(specificity 20),
even though .button.disabled
is written later in the CSS.
This simple change brings a lot more capabilities in theming your components for a dynamic look.
Convert any *StyleName
attribute to the according *Style
attribute. This is very useful for passing the sub-element styles (which are usually exposed by react-native libraries) directly from CSS.
If the styleName
value is an object or an array, automatically pipe it through the classnames
-like library.
Support for multiple named css file imports is removed
yarn add --dev babel-plugin-react-native-dynamic-stylename-to-style
or
npm install --save-dev babel-plugin-react-native-dynamic-stylename-to-style
.babelrc
You must give one or more file extensions inside an array in the plugin options.
{
"presets": [
"react-native"
],
"plugins": [
["react-native-dynamic-stylename-to-style", {
"extensions": ["css"]
}]
]
}
Anonymous reference can be used when there is only one stylesheet import.
