如何在本机应用程序和网站中实现位置的实时跟踪？

I have an ecommerce website and ecommerce app. We sells different products. What I want to do is like uber or grab app that can track real time location of the taxi going to my location. So in my app, everytime the delivery boy delivers the product to the customer, the delivery boy will see the exact location and direction of his destination. The same as the customer, he/she can see the exact location of the delivery boy. Is it possible to do in react native app and website? Please help, I am really new to this. Thank you!I have an ecommerce website and ecommerce app.
