SI: Essentials
The main API, library and toolkit by Soncresity Industries.
Quick answer
Which SI: Essentials release matches Fabric?
SI: Essentials 2.3.2 targets 1.21.10 with Fabric. Installation on the client is optional. Installation on the dedicated server is optional. 1 required mod needs a matching file.
Where it goes
Is SI: Essentials required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does SI: Essentials 2.3.2 need?
2.3.2 on Fabric. Every mod below is checked against that same setup.
Install Fabric API first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match.
We only count dependency files that match this setup. A file for another loader does not fill the gap.
Before you install it
Add SI: Essentials without breaking your instance.

About this project
What does SI: Essentials add?
🌐 SI: Essentials
The main API, library and toolkit by Soncresity Industries.
✨ Overview
SI: Essentials is an API, library and toolkit, all in one mod. It's a great pick for anyone looking to improve their modpack or developing their own mod.
🔧 Features
Remover Module
The Remover submdule allows you to disable certain items in the game. You can do that through IDs, Components and regular expressions (regex). You can either disable the item completely or only disable specific operations/features such as attacking/interacting with the item or its recipes.
Logger
SI: Essentials comes with a custom logger, that is based on the slf4j logger that is commonly used in Minecraft Mods. With our setup, we allow to create separate log files for each world that only contain the output of your mod. This makes finding issues in your code faster.
Our logger also comes with a debug option that is controlled with the global debug_enabled value of the SI: Essentials Common Cnfg. While debug output is only visible depending on that value in the Minecraft logs, debug output will always be logged to your custom logfile that was explained above.
Configuration API
Our Configuration API allows you, as a developer, to create multiple configurations in your projects and access and set configuration keys and values. Currently, you can choose the cnfg or the objt file type.
Command Utilities
The Command Utilities class allows you to execute commands as a player while being able to customize the permissions, position and rotation.
Decimal Utilities
The Decimal Utilities class allows you to round a decimal value to a set number of decimal points / places after the comma.
File Hash Utilities
The File Hash Utilities class allows you get the SHA256 file hash / checksum of a file as a String.
Item Utilities
The Item Utilities class allows you parse Items and Item Stacks from Strings or vice versa.
Message Utilities
The Message Utilities class allows you to send (privately and broadcast) messages (in the chat or Action Bar) with the Adventure/MiniMessage API.
Registry Utilities
The Registry Utilities class makes the process of registering Items and Blocks easier by providing useful helper methods.
Singleplayer Utilities
The Singleplayer Utilities class allows check whether a ServerPlayer is the host of a Singleplayer World. This may be useful when your Mod includes banning players but you don't want to ban the world host as otherwise their world wouldn't get saved properly and other players would get kicked.
Slot Utilities
The Slot Utilities class allows you to get the x and y position of a slot in a large chest GUI. This is useful for our Slot presets
Sound Utilities
The Sound Utilities class allows you to parse Sound IDs to a SoundEvent which you can then use to either play a sound privately for one player or broadcast it.
Title Utilities
The Decimal Utilities class allows you to show and broadcast fully customizable Titles to players using the Adventure/MiniMessage API.
