SPA - Single Page Application

An application providing the user a single page.  The page changes DOM elements dynamically typically through the use of a front end framework, like Angular, React, or Vue.  These types of applications do not refresh the entire page alleviating wait times and leave the web browser, rather than the web server, responsible for rendering markup and navigation.

SSE - Server Sent Events

Server Side Rendering

When a browser makes a request for content, the server sends all HTML markup to support the rendering of a page.  This is still common practice for sites that are dynamic in content and need to send markup quickly to the client.  It's good for crawlers too for indexing where it doesn't rely on the browser to render markup as practices would with SPA applications.

Long Polling

A method in which a client makes HTTP requests until a desired response is received or looking to return fresh data after a certain amount of time.

This can be useful in the case of asynchronous operations and no web hook events are available.  See Google Cloud SQL - Import 100k+ Records to MySQL for an example.
