Single code base of website, mobile site and native app

We are offering customer service in all the 3 mediums - Web Site, Mobile Site (PWA) and Native App (Android and iOS). We are maintaing 3 different code base and some parity exists in terms of some features available only in Native App.

Now my business team wants to move in a faster phase and I am thinking of moving to a single code base with which I can cater all the 3 mediums. In this sense which one is best to take :

ReactJS VueJS

I am new to both and completely have no idea about these. Is there any other options please let me know

Thanks in advance!
