Discord Background Image

DiscordBackgroundImage.js

(function () {
	var matchStr = "[class^=messagesWrapper] > [class^=scrollerWrap] > [class^=scroller]" // The selection string, Discord might change this...
    var imgURL = "https://i.imgur.com/4TiFTqP.jpg"; // Set your image URL here!
    var delay = 60 // Higher is slower, Lower is faster but may lag. (This value is in milliseconds!)
   
    var buildObserverX = function() {
        let t; // Some micro optimization magic stuff. Is it really needed? Hell if I know...
        let x = new MutationObserver(function (e) {
            if (t) clearTimeout(t);
            t = setTimeout(() => {
                let messagesWrapper = document.querySelector(matchStr);
                if (messagesWrapper && messagesWrapper.hasBackgroundSet !== true) {
                    init();
                }
            }, delay);
        });

        x.observe(document.getElementById("app-mount"), {
            childList: true,
            subtree: true
        });

        buildObserverX = undefined;
    }

    let init = function() {
        let messagesWrapper = document.querySelector(matchStr);

        if (messagesWrapper && typeof messagesWrapper === "object") {
            messagesWrapper.setAttribute("style", "background: linear-gradient( rgba(0, 0, 0, 0.65), rgba(54, 57, 63, 1) ), url(" + imgURL + ")!important;background-size: cover!important;");
            messagesWrapper.hasBackgroundSet = true;
        }

        if (typeof buildObserverX === "function") {
            console.log("Binding Observer...")
            buildObserverX();
            console.log("Observer Bound!")
        }
    }

    init(); // Initial Launch!
})();

This should work on Windows, Mac and Linux!

HOW TO USE

1. Open Discord.
2. Press ctrl+shift+i (command+option+i on Mac). This will be referred to as console.
3. Read the warning and if you decide that you don't trust me, then don't continue.
4. Copy and paste the code above into console.
5. Everything should now work, to remove restart/refresh (ctrl+r) Discord.

PLEASE NOTE

It is highly unlikely that you will get banned or punished in any way for using the code above. However, if something goes wrong and Discord threatens your family by name, or sends a representative to remove your reproductive organs, or if the script has any other undesirable effect. Don't blame the author of this script!

tl;dr Use at your own risk!
