[Solved]-Change one of params in url with react-router v4-Reactjs

import pathToRegexp from 'path-to-regexp';

const { match: { path, params } } = this.props;

pathToRegexp.compile(path)({
  ...params,
  cityGuid: 'newCityGuid',
})

If you want to keep the full location and change some parameters if you are in a nested route, you can do it with pathToRegexp, url and path from match and pathname from location.

const ParamLink = ({
  children,
  match: { url = '', path = '', params: currentParams = {} } = {},
  location: { pathname = '' } = {},
  params = {}
}) => {
  const urlPartToInsert = pathToRegexp.compile(path)({
    ...currentParams,
    ...params
  });
  const to = pathname.replace(url, urlPartToInsert);
  return <Link to={to}>{children}</Link>;
};

export default ParamLink;
