Please use this regex

\b(?:https?:\/\/|www\.|ftp:\/\/)[^\s]*

Explanation

  • \b Word boundary
  • (?: Non-capturing group
    • https?:\/\/|www\.|ftp:\/\/ Match either http:// or https:// or www. or ftp://
  • ) Close non-capturing group
  • \S* Anything except the space

Also, see the demo

Python Example

import re

text = """http://google.com is same as google.com.
https://stackoverflow.com is my favorite community.
Visit www.stackoverflow.com every day.
ftp://google.com/photos/upload"""

re.findall(r"\b(?:https?:\/\/|www\.|ftp:\/\/)\S*", text)  # ['http://google.com', 'https://stackoverflow.com', 'www.stackoverflow.com', 'ftp://google.com/photos/upload']

JavaScript Example

let text = `http://google.com is same as google.com.
https://stackoverflow.com is my favorite community.
Visit www.stackoverflow.com every day.
ftp://google.com/photos/upload`

text.match(/\b(?:https?:\/\/|www\.|ftp:\/\/)\S*/g)  // ['http://google.com', 'https://stackoverflow.com', 'www.stackoverflow.com', 'ftp://google.com/photos/upload']
