Package Exports

css-selector-extract

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (css-selector-extract) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

css-selector-extract

With selector extracting, it is possible to extract only certain CSS selectors form (S)CSS code. This is especially useful if you want to extract only a few CSS classes from a huge library or framework.

Demos

const cssSelectorExtract = require('css-selector-extract');

// CSS source code as string.
let css = '.btn { ... } .btn-alert { ... } .btn-success { ... }';
// Array of selectors which should be extracted.
let selectors = ['.btn'];

// Asynchronous:
cssSelectorExtract.process(css, selectors).then((css) => {
  console.log(css); // Outputs: `.btn { ... }`.
});

// Synchronous:
css = cssSelectorExtract.processSync(css, selectors);
console.log(css); // Outputs: `.btn { ... }`.

Rename extracted selectors

const cssSelectorExtract = require('css-selector-extract');

// CSS source code as string.
let css = '.btn { ... } .btn-alert { ... } .btn-success { ... }';
// Array of selectors which should be extracted.
let selectors = ['.btn'];
// Define replacements for extracted selectors.
let replacementSelectors = { '.btn': '.button' };

// Asynchronous:
cssSelectorExtract.process(css, selectors, replacementSelectors).then((css) => {
  console.log(css); // Outputs: `.button { ... }`.
});
