Modify the page with React jsx tags in any component. Set title, metadata, etc.
WARNING: This does not work for Facebook or Twitter sharing metadata! Those tags must be added server-side - dynamic tags don't get picked up by the scrapers. If you have a dynamic site, this can be a pain. One solution is to share a different url, where the server includes the og: meta tags
Example:
<Title title='Hello World :)' />
