Minecraft | How to install custom Fabric Version and Fabric API

Installing Fabric on your server

Fabric is a lightweight, experimental modding toolchain for Minecraft.

It is always good practice to back up your files before making changes, so we recommend backing up files

Installing Fabric Version

Open FabricMC website: https://fabricmc.net/use/server/
Select the Minecraft Java version you prefer. Do not touch the Installer Version & Fabric Loader Version, keep it default unless you know what it is.
Click on Executable Server (.jar) button to download the Fabric Jar
After downloading rename the file you downloaded to server.jar
Upload the server.jar to your server in the main directory

Depending on your specific goals, you may need to either delete all the files on your server for a fresh Fabric installation or simply replace the jar files in the main directory of your server to update your Fabric version. In general, a complete deletion of all server files is necessary when downgrading the version, while a version update only requires replacing the jar file. As mentioned previously, it is advisable to create a backup before making any changes. This way, you can easily undo them and keep your files safe to prevent data loss.

Start your server.

Installing Fabric API

Fabric API is the core library for the most common hooks and intercompatibility measures utilized by mods using the Fabric toolchain
