squaremap is a Minecraft server plugin/mod that renders live top-down world maps to a web interface, similar to Dynmap but with a minimalist design. It supports multiple server platforms (Paper, Fabric, NeoForge, Sponge) through a shared core module with platform-specific adapters, built using Gradle multi-module and a custom build-logic. The backend captures chunk snapshots via mixins/access transformers, renders them into PNG tiles using biome and block color data, and serves them via an embedded Undertow HTTP server. Tiles are generated asynchronously with a FIFO caching system, and the system provides commands for full/radius renders, pause/resume, and visibility controls. The web frontend is a Leaflet-based TypeScript app with player tracking, world selection, layer controls, and coordinate display. The project also exposes a public API for other plugins to add markers, layers, icons, and player managers. The architecture is cleanly separated into API, common, and platform-specific modules, with dependency injection (Guice) and standard libraries (Cloud command framework, Configurate, Adventure). It is actively maintained, with recent commits and support for bleeding-edge Minecraft versions, but the heavy reliance on internal Minecraft code and multiple platform-specific mixins introduces maintenance complexity and drift risk.
Sodium Extra is a client-side Minecraft mod that extends the Sodium performance mod with additional graphical options, visual bug fixes, and performance tweaks. Architecturally, it is a mixin-heavy mod built with the Architectury multi-platform toolchain, supporting both Fabric and NeoForge loaders. It injects into Minecraft's rendering, fog, particle, GUI, and entity systems via over 50 mixin classes, controlled by a custom mixin configuration system (CaffeineConfig). Key entry points include `SodiumExtraClientMod` (initialization, config registration, debug HUD), `SodiumExtraMixinConfigPlugin` (runtime mixin filtering based on user options), and platform-specific initializers (`SodiumExtraFabricClientModInitializer`, `SodiumExtraNeoForgeClientMod`). External dependencies are Sodium (required), Minecraft, and optionally ModMenu and Greenlight (for server-authorised fog). The mod is best described as 'OptiFine's eye-candy options for Sodium', providing fine-grained toggles for animations, particles, fog, sky/clouds, biome colors, toasts, overlays, and many performance-related features. It is not a data or research project.
