Vuetale

🧙 Sponsord by Hytale Modding Grant Program

Build Hytale mod UIs with Vue 3, TypeScript, and Kotlin/Java.

Vuetale is a Hytale mod library that brings modern frontend development to Hytale mod interfaces. Write reactive, component-based UIs in Vue SFCs, compile them through Vite, and drive them from your Kotlin/Java mod code — all with full type safety.

How It Works

Vuetale embeds a Node.js/V8 engine inside your mod's JVM process. Vue components are compiled by Vite at build time and output as JavaScript bundles into your mod's src/main/resources/vuetale/ folder. At runtime, Vue's render output is translated through a custom bridge into native Hytale UI elements — no HTML, no CSS parsing, no browser involved.

Vue SFC  →  Vite build  →  resources/vuetale/<module>/  →  loaded by JVM mod  →  native Hytale UI

Features

Vue 3 SFCs — write .vue files with <script setup>, composables, and full reactivity
Kotlin/Java API — open pages and push reactive data from server-side mod code
TypeScript types — companion CLI extracts type definitions from JARs for IDE support
Hot reload — iterate on UI without restarting the server
Tailwind CSS — Tailwind v4 supported out of the box in the starter project
Per-player isolation — each player gets their own Vue app instance

Quick Start

For an in-depth guide, see the Getting Started Guide.

1. Get Vuetale

Download from either

2. Clone the starter project

git clone git@github.com:KelpyCode/vuetale-starter.git --recurse-submodules my-mod-project
cd my-mod-project
rm -rf .git
rm -rf src/ui/.git

3. Place the JAR

Copy Vuetale-*.jar to lib/Vuetale.jar.

4. Validate the server (IntelliJ)

Sync Gradle dependencies.
Run runServer.
Copy Vuetale.jar into run/mods/.
Rerun the server and type /vuetale in chat — you should see the test UI.

5. Set up the UI project (VS Code → `src/ui`)

pnpm install
pnpm vt config server-mods <absolute-path-to-run/mods>
pnpm vt config resources <path-to-src/main/resources>
pnpm vt extract
pnpm vt dev true
pnpm watch

That's it. Vite watches your Vue files and outputs compiled bundles into src/main/resources/vuetale/<module>/, which the server picks up automatically.

Usage

Register your module (Kotlin)

// In your plugin setup function
ModuleRegistry.registerModule("myMod", Plugin::class.java)

Open a UI page for a player

val ui = PlayerUiManager.openPage(
    playerRef,
    ref as Ref<EntityStore>,
    store as Store<EntityStore>,
    "myMod",   // matches vuetale-plugin.json name
    "TestPage" // matches src/ui/lib/pages/TestPage.vue
)

// Push data to the Vue page
ui.setData("playerName", "Steve")
ui.setData("health", 20)
ui.setData("items", listOf("Sword", "Shield", "Potion"))

Any serializable value works — primitives, lists, maps, and data classes.

Consume data in Vue

<script setup lang="ts">
    import { useData } from 'vt:@core/composables/useData'
    import { Common } from 'vt:@core/components/Common'

    const playerName = useData<string>('playerName', 'Unknown')
    const items = useData<string[]>('items', [])
</script>

<template>
    <Common.DecoratedContainer :anchor="{ Width: 500, Height: 300 }">
        <template #title>
            <Common.Title :text="`${playerName}'s Inventory`"/>
        </template>
        <template #content>
            <Group layout-mode="TopScrolling" :anchor="{ Full: 1 }">
                <Common.TextButton
                        v-for="item in items"
                        :key="item"
                        :text="item"
                        @activating="() => console.log(item)"
                />
            </Group>
        </template>
    </Common.DecoratedContainer>
</template>
