There are many solutions for pushing data from a server to a (web) client. Some examples from Firebase:

Firebase's Realtime Database SDKs use Web Sockets for maintaining its connection between client and server.
When you access Firebase Realtime Database using its REST API, you can use server-sent events (SSE) to accomplish streaming updates.
Cloud Firestore uses long-polling requests over HTTP/2. There are many solutions for this type of connection.
