Provide a simple lookup to check if a provided selector targets a pseudo class or element.
Although there are already some projects which refer towards a list of pseudo classes or elements - they are not convenient to use for a simple lookup. On the contrary this library provides a simple validation function which also include browser vendor specific selectors and common extensions defined by jQuery & CSS Select.
npm install --save is-pseudo
import isPseudo from 'is-pseudo'
if (isPseudo('div a.super:hover')) {
// true
}
if (isPseudo('div span:has(a)', { customs: true })) {
// true
}- add strict comparison option for selectors with brackets (e.g.
:nth-child(3))
To build your own version run npm run dev for development (incl. watch) or npm run build for production (minified).
