Match HSLA color strings

This feature allows you to match HSLA color strings within a larger string. The code sample demonstrates how to use the hsla-regex package to find an HSLA color string in a CSS declaration.

const hslaRegex = require('hsla-regex');
const str = 'background-color: hsla(120, 100%, 50%, 0.3);';
const match = str.match(hslaRegex());
console.log(match); // ['hsla(120, 100%, 50%, 0.3)']

Validate HSLA color strings

This feature allows you to validate whether a given string is a valid HSLA color string. The code sample shows how to use the hsla-regex package to check if a string is a valid HSLA color.

const hslaRegex = require('hsla-regex');
const isValidHsla = (str) => hslaRegex().test(str);
console.log(isValidHsla('hsla(120, 100%, 50%, 0.3)')); // true
console.log(isValidHsla('rgb(255, 0, 0)')); // false
