What is script-loader?

Script Loader is a browser extension that injects custom JavaScript into a web-based game called TagPro. The practical benefit is that players can run their own scripts or modifications while playing the game, customizing the experience without altering the game itself. At a high level, the extension takes one input: a URL pointing to a JavaScript file that uses a system called RequireJS. When a TagPro game is active, the extension fetches that script and injects it into the page so it runs alongside the game. There is a technical requirement, the server hosting the script must return a specific access-control header, otherwise the extension will not be able to load it due to browser security rules. The people who would use this are TagPro players who want to run custom scripts during their matches. For example, a player might host a script that adds extra UI elements, tracks statistics, or tweaks certain behaviors, then point the extension at that script's URL. Each time a game starts, the extension automatically loads and runs it. The README doesn't go into detail about what kinds of scripts people typically use or what features they add, it only describes the injection mechanism. What's notable is the project's narrow scope. It does exactly one thing: inject a script from a given URL when TagPro is running. There is no built-in configuration beyond that single input, no library of scripts, and no interface for managing multiple scripts. The access-control requirement is a tradeoff of the browser-extension approach, it keeps things simple but means the script must be hosted somewhere that explicitly permits cross-origin loading.
