Compose API
Compose API is an API that imports the dependencies required for JetBrains' technology called Compose. Required for the Voxel Studio Pro project.
Quick answer
Which Compose API release matches 26.1.2?
Compose API 1.3.0 targets 26.1.2 with Fabric. It must be installed on the client. Do not install it on the dedicated server. All 1 required mods have matching files.
Where it goes
Is Compose API required on the client, server, or both?
It must be installed on the client. Do not install it on the dedicated server.
This file is marked client-only.
What else does Compose API 1.3.0 need?
1.3.0 on 26.1.2. Every mod below is checked against that same setup.
Install Fabric Language Kotlin first. We found matching files for this game-version and loader setup.
We only count dependency files that match this setup. A file for another loader does not fill the gap.
Before you install it
Add Compose API without breaking your instance.
Built for Compose API 1.3.0 on 26.1.2. Pick another file and the loader, install side or required mods may change.

About this project
What does Compose API add?
Compose API - Fabric
Compose API, imports the dependencies required for JetBrains technology called Compose.
This mod does not add any features on its own.

Why ?
Compose is a technology I'll be using in a major upcoming mod that has been in development for years.
With the following benefits :
- No need to include it in your mods.
- Can be reused by multiple mods.
- Supports MacOS ARM, Windows x64, and Linux x64.
- Includes a minimal API that disables Compose if unavailable.
- Avoids re-downloading Compose entirely when mods that use it are updated.
- Compose has an interesting Vulkan-compatible backend

Voxel Studio Pro :
In future mods it will allow integrating an in-game interface similar to Hytale's asset editor, or to Unity/Unreal Engine. A game editor built into the game, which can be used either:
- For players, Customize your gameplay experience.
- For developers, making it much easier to develop datapack/resource pack/mods content and manage modpacks.
- For game designer, Easily adjust the game balancing without bothering the developers, Amazing for a server.

How to install
JetBrains Compose uses Kotlin, so don't forget to install the mods.
Step one - Add Modrinth to your gradle repository :
repositories {
maven {
name = "Modrinth"
url = "https://api.modrinth.com/maven"
content {
includeGroup "maven.modrinth"
}
}
}
Step two - Add Compose to your Gradle Dependencies
compose.desktop.currentOs is a helper from the Compose Gradle plugin that resolves to the Compose Desktop artifact matching the host OS at build time, pulling in the right native Skia/Skiko
// Change the version if needed
modImplementation "maven.modrinth:compose-api:1.2.0"
implementation compose.desktop.currentOs
If you prefer to specify the Compose API versions in gradle.properties, you can use a variable modImplementation "maven.modrinth:compose-api:${project.compose_api_version}"
With the version in gradle.properties compose_api_version=1.2.0
Step three - Add Jetbrains Plugin in Grandle
plugins {
// ... Your Kotlin/Loom
id 'org.jetbrains.kotlin.plugin.compose' version '2.3.10'
id 'org.jetbrains.compose' version '1.9.1'
}

What does it contain?
This mod contains all the dependencies required for Compose to work on MacOS ARM, Windows x64, and Linux x64. It can be used by any other modder.
It does not include Kotlin dependencies to avoid downloading them twice, with the Fabric Kotlin mods.
This mod gives you access to :
- The
androidx.compose.*API. - The Jetbrains Skia
org.jetbrains.skiaAPI
ComposeAPI.isAvailable function, which checks whether the operating system is compatible. This allows mod developers to simply disable their composite interfaces if the user's system is not compatible.
Everything else is available in the documentation from Google and JetBrains, the creators of Compose.
You'll find tons of tutorials on YouTube or on Claude/Codex.
