inject

by Brawls

inject is a Fabric library for Minecraft 1.21 – 26.2 that lets other mods inject Netty pipelines and handle raw HTTP requests on a server.

FabricServer-side onlyMIT LicenseOpen source1.21 – 26.2

What it does

Developers use the library to hook Netty, the networking framework behind Minecraft's connections, without writing the injection code themselves. It provides a set of modules for common web stacks, including Spring Boot, Javalin, Ktor and Jetty, so a server can accept HTTP requests alongside game traffic.

Requests can be handled manually through the http module, and the examples module shows how an injector responds with a fixed message. Spigot, Paper and Purpur derivatives use the InjectSpigot class, and the project lists Paper, Spigot, Purpur and Folia as server platforms it can run on. The library runs on the server only, so players join without installing it, and it is released under the MIT License as open source.

Key features

  1. Netty injection

    The library makes it simpler to inject handlers into Netty, so other mods do not need their own low-level code.

  2. Web framework modules

    Separate modules cover Spring Boot, Javalin, Ktor and Jetty, letting a server expose HTTP endpoints with a familiar stack.

  3. Manual request handling

    An http module lets developers process incoming HTTP requests directly, without a framework.

  4. Bundled examples

    An examples module shows a working HTTP injector that replies with a short text message.

This will register an HTTP injector which will respond with Hello, from Minecraft! to any HTTP request to the Minecraft port. Examples can be found in the examples module.
