ChatDebug
by TriPledOp
ChatDebug lets a player inspect the raw JSON of chat messages the client receives, which helps when a chat component behaves unexpectedly.
What it does
The mod opens a popup that shows the JSON of each chat message the client receives, with syntax highlighting. The view is useful for debugging complex chat components and for seeing how the text is built behind the scenes, including on other servers. The JSON can be copied to the clipboard directly from the popup. ChatDebug is a client-side only mod for Fabric, with a single file for 1.21.5 released under the MIT License, and it is open source. It requires Cloth Config API and Fabric API, and Mod Menu is optional.
