const match = str.match(rgbaRegex());
console.log(match); // ['rgba(255, 99, 71, 0.5)']

Validate RGBA color strings

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

const rgbaRegex = require('rgba-regex');
const isValidRgba = rgbaRegex().test('rgba(255, 99, 71, 0.5)');
console.log(isValidRgba); // true
