Vein Miner
Vein Miner breaks a whole connected vein of ore or a full tree when a player breaks a single log or ore block, on a Fabric server.
What it does
When a player breaks one ore block or log, Vein Miner removes every directly connected block of the same kind in a single action. By default only ores and logs are affected, so other blocks stay untouched. Ore veins also count diagonally connected blocks, since ores connect through 26 neighboring positions, while logs connect only through direct face-to-face contact. The result is faster ore mining and tree chopping without accidentally clearing ordinary blocks.
The mod is server-side only, so players join without installing anything and only the server needs Fabric API and Vein Miner. Its configuration file is generated automatically and keeps saved values across updates. Restart the game or server after editing it. Options include a vein limit, which defaults to 64 blocks per break, and an optional all-blocks mode that extends the behavior to any block type. Each block removed costs the held tool durability, just as it does in vanilla, and the chain ends before the tool would break.
Key features
Connected vein mining
One break removes the whole connected group of matching ore or log blocks in a single action.
Diagonal ore detection
Ore blocks connect through faces, edges and corners, so diagonal ore pockets are included in a vein.
Tree mining
Directly connected logs are chopped together, without breaking each block individually.
Optional all-blocks mode
Enabling it lets a matching block type be mined as a vein, for broader behavior than the default.
Durability protection
Durability is spent on the held tool for every block removed, and the chain halts ahead of the point where the tool would break, following vanilla rules.
Configurable vein limit
The number of blocks mined per break is set in the configuration file, with a default of 64.

OreDetector is server-side only but not open source, under All rights reserved, and targets 1.21.11 alone.
