Minecraft:Java Edition protocol/Slot data

The Slot data structure defines how an item is represented when inside an inventory window of any kind, such as a chest or furnace.

This page presents the new Slot data structure, using structured components. You can find the documentation of the old structure, that utilizes raw NBT data, here.

Format

Name		Type		Meaning
Item Count		Template:Type		The item count. Every following field is only present if this value is greater than zero.
Item ID		Template:Type Template:Type		ID in the minecraft:item registry. Item IDs are distinct from block IDs; see Data Generators for more information.
Number of components to add		Template:Type Template:Type		Number of elements present in the first data component array
Number of components to remove		Template:Type Template:Type		Number of elements present in the second data component array. This serve as a way to remove the default component values that are present on some items.
Components to add	Component type	Template:Type Template:Type	Template:Type Template:Type	ID in the minecraft:data_component_type registry, indicating the type of the component and the format of data to follow.
	Component data		Varies	The component-dependent data. See structured components for more detail.

Hashed format

Similar to the usual slot format, but with the notable difference that data component values are encoded as CRC32C (note: CRC32C is not the same thing as CRC32) checksums. The way the checksum is generated is currently undocumented. It's currently only used in the click container packet.
