webSAF - front-end architecture and design

webSAF is an easy-to-use, web-based tool for simulation-supported, two-sided wargaming. It consists of a server that communicates with a graphical user interface (GUI) in the browser using WebSocket. It currently has functionality for controlling indirect fire entities, maneuver entities and air defence entities. webSAF is designed to be independent of the simulation tools in use, and can be used to control entities in a federation of different simulation tools. The web-based user interface (UI) is written in TypeScript, a superset of JavaScript, and is based on a selection of web technologies, the most important being React, Redux and OpenLayers. This report describes the technologies, decisions that were made and experiences related to development of the GUI.
