What is Composer?

Composer is a general-purpose Fabric library mod developed under Project Codex.
It provides shared systems, utilities, and architectural building blocks used across multiple mods, with a focus on clean APIs, long-term stability, and multi-version support.

Composer does not add gameplay content on its own (except for a plushie). It exists to support other mods at runtime and during development.

For more details, take a look at the wiki!

Development Usage

If you want to use Composer as a library in your mod, add the Composer Maven repository and Cardinal Components
repository to your build file, then add Composer as a dependency.

Replace (latest_version) with the latest Composer version compatible with your Minecraft version.

Gradle (Groovy DSL) – build.gradle

# gradle.properties
composer_version = (latest_version)

// build.gradle

repositories {
    // Before 3.0
    maven {
        name = "Composer Maven"
        url = "https://dl.cloudsmith.io/public/lilbrocodes/composer-reloaded/maven/"
    }
    
    // After 3.0
    maven {
        name = "Composer Maven"
        url = "https://dl.cloudsmith.io/public/project-codex/composer/maven/"
    }
    
    // After 3.0.4
    maven {
        name "Constructive"
        url "https://dl.cloudsmith.io/public/lilbrocodes/constructive/maven/"
    }
    
    maven {
        name = "Cardinal Components"
        url = "https://maven.ladysnake.org/releases"
    }
    maven {
        name "Fuzzy Hamsters"
        url "https://maven.fzzyhmstrs.me/"
    }
}

dependencies {
    // <2.0
    modImplementation "org.lilbrocodes:composer-reloaded:$composer_version"

    // >=2.0 <3.0
    modImplementation "org.lilbrocodes:composer-reloaded:$composer_version+mc$minecraft_version"

    // >=3.0
    modImplementation "com.codex:composer:$composer_version+mc$minecraft_version"
}

Gradle (Kotlin DSL) – build.gradle.kts

# gradle.properties
composer_version = (latest_version)

// build.gradle.kts

repositories {
    // Before 3.0
    maven("https://dl.cloudsmith.io/public/lilbrocodes/composer-reloaded/maven/") {
        name = "Composer Maven"
    }
    
    // After 3.0
    maven("https://dl.cloudsmith.io/public/project-codex/composer/maven/") {
        name = "Composer Maven"
    }

    // After 3.0.4
    maven("https://dl.cloudsmith.io/public/lilbrocodes/constructive/maven/") {
        name = "Constructive"
    }
    
    maven("https://maven.ladysnake.org/releases") {
        name = "Cardinal Components"
    }
    maven("https://maven.fzzyhmstrs.me/") {
        name = "Fuzzy Hamsters"
    }
}

dependencies {
    // <2.0
    modImplementation("org.lilbrocodes:composer-reloaded:$composer_version")
    
    // >=2.0 <3.0
    modImplementation("org.lilbrocodes:composer-reloaded:$composer_version+mc$minecraft_version")
    
    // >=3.0
    modImplementation("com.codex:composer:$composer_version+mc$minecraft_version")
}
