ConfigAPI
ConfigAPI is a library that lets other mods and plugins create JSON configuration files from a single class, and it reloads those files when they change.
What it does
ConfigAPI is a library for building JSON configuration files for mods and plugins. A developer declares the configuration in one class, and the API creates and initializes the file when the mod or plugin starts. The author notes describe it as a tool that the author's Banned Studios projects mostly use, so the design is shaped around those projects' needs.
An automatic reload system watches the configuration file and applies changes made to it, whether they come from a text edit or from a method call or command. Developers can also add actions that trigger a reload on demand. The library supports String, Integer, Long, Boolean, List and Map values, so a configuration can hold nested structures as well as plain settings.
ConfigAPI runs on Fabric, Forge and NeoForge, and it is also available for the Paper, Spigot, Bukkit and Purpur server platforms. Its files cover 1.16 – 26.2, with the latest builds for 26.2 on each loader. It is released under the Creative Commons Attribution 4.0 license and is not open source, though its source code and issue tracker are public. KeybindHider requires it.
Key features
Single-class setup
A configuration is defined in one class that initializes when the mod or plugin starts, with no separate loader code to write.
Automatic reload
Edits to the JSON file are picked up without a restart, and reload actions can be triggered from code.
Typed values
Strings, integers, longs, booleans, lists and maps can all be stored, including maps of lists and nested values.
Server platform support
Besides the three mod loaders, the library is available for Paper, Spigot, Bukkit and Purpur servers.
