npm install @csstools/media-query-list-parser @csstools/css-parser-algorithms @csstools/css-tokenizer --save-devMedia Query List Parser depends on our CSS tokenizer and parser algorithms.
It must be used together with @csstools/css-tokenizer and @csstools/css-parser-algorithms.
import { parse } from '@csstools/media-query-list-parser';
export function parseCustomMedia() {
const mediaQueryList = parse('screen and (min-width: 300px), (50px < height < 30vw)');
mediaQueryList.forEach((mediaQuery) => {
mediaQuery.walk((entry, index) => {
// Index of the current Node in `parent`.
console.log(index);
// Type of `parent`.
console.log(entry.parent.type);
// Type of `node`
{
// Sometimes nodes can be arrays.
if (Array.isArray(entry.node)) {
entry.node.forEach((item) => {
console.log(item.type);
});
}
if ('type' in entry.node) {
console.log(entry.node.type);
}
}
// stringified version of the current node.
console.log(entry.node.toString());
// Return `false` to stop the walker.
return false;
});
});
