Spark Web API

A small plugin that will host a Web API for Spark.

This plugin is made for Paper. You are free to fork
this on GitHub and port this to other mod loaders.

This README is a simplified version of the Project's GitHub README.

Installation

First, Install Spark to your Paper server.
Even though Paper servers for Minecraft 1.21 and up
has Spark built-in, a standalone plugin version is
required for this plugin.

Then, Install Spark Web API. You generally would download
the JAR with -all at the end of the file name.

When starting your server, Please remember to set the
paper.preferSparkPlugin system property to true

Here's an example on how to do so:

java -Dpaper.preferSparkPlugin=true -jar paper-1.21-129.jar

Configuration

When starting the server for the first time with the
plugin, The plugin will generate a config file.
The config file allows you to change the port of the
server, which routes are enabled, and add additional
headers to responses.

port: 3000
routes:
  tps: true
  mspt: true
  sys_cpu: false
  proc_cpu: false
  gc: false
headers:
  enabled: false
