A simple JavaScript utility for conditionally joining inline styles together.
This is a fork of the unmaintained stylenames package
In one short sentence: "stylenames converts an object to a css style string."
Think classNames but for inline styles.
From CDN: Add the following script to the end of your <head> section.
<script src="https://cdn.jsdelivr.net/npm/@shat/stylenames@v1.x.x/lib/index.umd.js"></script>That's it. It will initialize itself as styleNames().
From NPM: Install the package from NPM.
npm install @shat/stylenamesInclude it in your script.
import styleNames from '@shat/stylenames';Standalone:
styleNames({
backgroundColor: 'red',
width: '120px',
'height':{
// If the condition is false the style does not get used.
'200px': false,
// Only the first value with true condition is used.
'300px': true,
'400px': true
},
});With Alpine.js:
<script src="https://cdn.jsdelivr.net/gh/alpinejs/alpine@v2.x.x/dist/alpine.min.js" defer></script>
<div x-data="{}">
<button :style="styleNames({ backgroundColor: 'red', padding: '20px' })">
A red button
</button>
</div>
<script src="https://cdn.jsdelivr.net/npm/@shat/stylenames@v1.x.x/lib/index.umd.js"></script>let styles1 = styleNames({
height: '120px',
width: '100px'
});
console.log(styles1); //--> 'height:120px;width:100px;'let styles1 = styleNames({
height: '120px',
width: {
'200px': false
}
});
console.log(styles1); //--> 'height:120px '
let styles2 = styleNames({
height: '120px',
width: {
'200px': true
}
});
console.log(styles2); //--> 'height:120px;width:200px;'const styles = styleNames({
'height:120px;width:100px;': true
});
console.log(styles); //--> 'height:120px;width:100px;'const styles = styleNames({backgroundColor: 'red'});
console.log(styles); //--> 'background-color:red;'const styles = styleNames(['height:120px', 'width:100px']);
console.log(styles); //--> 'height:120px;width:100px;'let itemCount = 0;
let styleNamesConfig = {
display: {
'none': () => itemCount === 0
},
height: '120px',
width: {
'100px': () => itemCount <= 1,
'200px': () => itemCount <= 2,
'400px': () => itemCount <= 4,
'100%': () => itemCount > 4
}
};
console.log(styleNames(styleNamesConfig)); //--> 'display:none;height:120px;width:100px;'
itemCount++; //1
console.log(styleNames(styleNamesConfig)); //--> 'height:120px;width:100px;'
itemCount++; //2
console.log(styleNames(styleNamesConfig)); //--> 'height:120px;width:200px;'
itemCount++; //3
console.log(styleNames(styleNamesConfig)); //--> 'height:120px;width:400px;'
itemCount += 12; //15
console.log(styleNames(styleNamesConfig)); //--> 'height:120px;width:100%;'- Node 10
