# KappaEssentials Extension Loader<\/p>\n
A **_lightweight_** and **_secure_** extension system for KappaEssentials
\n> Supports Paper 1.21+ \u00b7 Java 21
\n# What is it?<\/p>\n
KappaEssentials Extension Loader allows you to safely load modular .jar extensions for the KappaEssentials plugin.<\/p>\n
It’s a separate plugin that reads .jar files from a specific folder and loads them only if they are explicitly allowed by their internal ID.
\n# How it works<\/p>\n
– On startup, the loader looks inside:
\nplugins\/KappaEssentials\/extensions\/<\/p>\n
– Each .jar must contain an extension.yml file with:<\/p>\n
– id: my-extension
\nmain: my.package.MyExtensionClass<\/p>\n
– The loader only enables .jar files with IDs that are hardcoded in its whitelist.<\/p>\n
– It loads the main class, initializes it, and calls onEnable() and onDisable() on shutdown.<\/p>\n
# Features<\/p>\n
– Modular, keep KappaEssentials clean and minimal<\/p>\n
– Simple API, just implement KappaExtension<\/p>\n
– Supports Paper 1.21+, built for modern servers<\/p>\n
– Open design, more extensions coming soon!
\n# For Extension Developers<\/p>\n
Extensions must:<\/p>\n
– Be valid .jar files<\/p>\n
– Contain an extension.yml at root:
\n“`
\nid: example-extension
\nmain: net.example.MyExampleExtension
\n“`<\/p>\n
**More dev tools, examples, and extension templates will follow.**<\/p>\n
