POSTED ON:

TAGS: javascript

Brilliant! This uses the web APIs URL() - MDN.

const isValidURL = (url) => {
  try {
    new URL(url);
    return true;
  } catch (error) {
    return false;
  }
};

isValidURL("https://dev.to");
// true

isValidURL("https//invalidto");
// false

new URL('/en-US/docs');                        // Raises a TypeError exception as '/en-US/docs' is not a valid URL
new URL('http://www.example.com', );           // => 'http://www.example.com/'
