TangoWebAPI

A single shared webserver mod for Fabric/NeoForge that removes boilerplate for other mods. TangoWebAPI provides one embedded HTTP server that mods can use to expose their own endpoints or static assets.

Features

• Shared HTTP server (Java HTTP) for all mods, start/stop in common code.
• Simple API for routes: get/post/registerRoute with mod namespace (/modid/...).
• Static file serving per mod (serveStatic with safe path handling).
• Built-in health/info/route listing: /tango-webapi/health, /tango-webapi/info, /tango-webapi/routes.
• Configuration via file (config/tango-webapi.properties) or env/system props.
• Error pages (404/405/503) with simple HTML templates.

Configuration

File: config/tango-webapi.properties

host=0.0.0.0
port=8080
maxRequestBytes=1000000

Or via env/system properties:

• TANGO_WEBAPI_HOST / tango.webapi.host
• TANGO_WEBAPI_PORT / tango.webapi.port
• TANGO_WEBAPI_MAX_BYTES / tango.webapi.max_bytes

API for other mods (examples)

// Simple text route at /mymod/ping
TangoWebAPI.get("mymod", "/ping", ctx -> ctx.sendText(200, "pong"));

// JSON response
TangoWebAPI.post("mymod", "/data", ctx -> ctx.sendJson(200, "{\"ok\":true}"));

// Static assets from config/mymod/static under /mymod/static/**
TangoWebAPI.serveStatic("mymod", "static", Path.of("config", "mymod", "static"));

Built-in endpoints

• GET /tango-webapi/health – status
• GET /tango-webapi/info – host/port/max-bytes
• GET /tango-webapi/routes – all registered routes incl. prefix routes

Testing

• After game start: http://localhost:8080/tango-webapi/health / info / routes
• Register your own route and hit it via browser/curl.
• Serve a static page under your mod path and verify it loads.
