Pattern

regexJS
(?:youtube\.com\/watch\?v=|youtu\.be\/|youtube\.com\/embed\/)([\w\-]{11})   (flags: g)

JavaScript / ECMAScript code

jsJavaScript
const re = new RegExp("(?:youtube\\.com\\/watch\\?v=|youtu\\.be\\/|youtube\\.com\\/embed\\/)([\\w\\-]{11})", "g");
const input = "https://www.youtube.com/watch?v=dQw4w9WgXcQ";
const matches = [...input.matchAll(re)];
console.log(matches.map(m => m[0]));

Uses `String.prototype.matchAll` for global iteration (Node 12+ / all modern browsers).

How the pattern works

Matches any of three URL forms (watch?v=, youtu.be/, embed/) and captures the 11-character video ID that follows. The ID uses word characters and hyphens.

Examples

Input

https://www.youtube.com/watch?v=dQw4w9WgXcQ

Matches

  • youtube.com/watch?v=dQw4w9WgXcQ

Input

https://youtu.be/dQw4w9WgXcQ

Matches

  • youtu.be/dQw4w9WgXcQ

Input

not a youtube url

No match
