From e4f162b3ca3d7646851282ac4cd340022e605251 Mon Sep 17 00:00:00 2001 From: stijnnjakobs Date: Fri, 14 Nov 2025 13:04:05 +0100 Subject: [PATCH] fix(mongo): disable implicit player document initialization in NetworkDataAPI Prevent automatic creation of default MongoDB documents on player join. NetworkDataAPI should only expose a shared MongoDB connection layer, without managing or provisioning plugin data. Removed implicit initialization logic so custom plugins retain full control over their own schemas and document creation. --- API_DOCUMENTATION.md | 394 ++++++++++++++++-- EXAMPLE_PLUGIN_GUIDE.md | 17 +- IMPLEMENTATION_NOTES.md | 294 +++++++++++++ README.md | 173 +++++++- .../networkdataapi/bungee/NetworkDataAPI.java | 12 - .../bungee/PlayerConnectionListener.java | 26 +- .../core/service/PlayerDataService.java | 18 +- .../networkdataapi/paper/NetworkDataAPI.java | 12 - .../paper/PlayerConnectionListener.java | 26 +- 9 files changed, 866 insertions(+), 106 deletions(-) create mode 100644 IMPLEMENTATION_NOTES.md diff --git a/API_DOCUMENTATION.md b/API_DOCUMENTATION.md index 165e52c..91046bd 100644 --- a/API_DOCUMENTATION.md +++ b/API_DOCUMENTATION.md @@ -16,7 +16,26 @@ ## Overview -NetworkDataAPI is an enterprise-grade data synchronization solution for large Minecraft networks (similar to Hypixel or CubeCraft).

IMPORTANT: This listener is NOT automatically registered by NetworkDataAPI. + * It serves as an example implementation for custom plugins that want to manage player data.

+ * + *

NetworkDataAPI is a database connection layer only. Custom plugins should implement + * their own listeners if they need to track player joins/quits.

+ * + *

This example listener demonstrates how to:

*
    - *
  • Loads player data when they join the server
    • - *
  • Updates last login timestamp
    • - *
  • Pre-caches player data for instant access

Usage in your custom plugin:

+ * 
{@code
+ * NetworkDataAPIProvider api = APIRegistry.getAPI();
+ * PlayerDataService playerDataService = api.getPlayerDataService();
+ * getServer().getPluginManager().registerEvents(
+ *     new PlayerConnectionListener(playerDataService),
+ *     this
