Common terminology used in web development.

Isomorphic

Isomorphic code (aka universal code) is code that can be loaded and executed on both the client- and server-side.

HMR

HMR (Hot Module Replacement, aka live reload) is a development feature that updates modules in a running application without requiring a full page reload, preserving application state.

SSG

SSG (Static Site Ggeneration, aka pre-rendering) is a web development approach where all pages are pre-rendered to HTML at build time, so that your app consists only of static assets that can be deployed to a static host which is fast, easy, and inexpensive (usually free).

Technically speaking: an SSG app is an app where all pages are pre-rendered (prerender.partial is false).
