This covers most LinkedIn profile URLs (Javascript RegEx):

• http://www.linkedin.com/in/username

• https://linkedin.com/in/username

• http://www.linkedin.com/mwlite/in/username

• https://www.linkedin.com/mwlite/in/username

• http://linkedin.com/mwlite/in/username

• https://linkedin.com/mwlite/in/username

• http://www.linkedin.com/m/in/username

• https://www.linkedin.com/m/in/username

• http://linkedin.com/m/in/username

• https://linkedin.com/m/in/username

// Generic RegEx exact match validator
export const isRegexExactMatch = (value, regexp) => {
  const res = value.match(regexp);
  return res && res[0] && res[0] === res.input;
};

const isLinkedinProfileUrl = (value) => {
  const linkedInProfileURLRegExp =
    '(https?:\\/\\/(www.)?linkedin.com\\/(mwlite\\/|m\\/)?in\\/[a-zA-Z0-9_.-]+\\/?)';
  return !!isRegexExactMatch(value, linkedInProfileURLRegExp);
};
