How do I install GuiJS?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on CurseForge — not every file is mirrored on our own servers.

What Minecraft version does GuiJS work with?

The listing gives Minecraft 1.20.1. This is the version stated by the author or source site, not something we verified ourselves.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

GuiJS is a Mod that allows you to create your own GUI on Client Side.

I've tried my hardest while making the Wiki to give a easy time utilizing the mod explaining how features work and giving templates to help with GUI creation.

GuiJS is fairly easy to use, even someone without any KubeJS knoweldge could make a GUI.

For most of the GUI stuff it's all done through the Client Scripts folder, there is one file which needs to be made in the Startup Scripts but other than that all you should need to do is press F3+T to reload your GUI in game.

If you would like to get into contact with me regarding adding new features, updating old ones to function better, or have general ideas or suggestions please send them in my Discord.
