Summary
Since 2.14.0, the building block architecture relies on passing the store as the first parameter to internal functions. This store was used as a WeakMap key to access building blocks. WeakMap access is not super performant so in certain heavy applications, performance was impacted.
This PR reworks the building block architecture to directly pass buildingBlocksContext
readonly [...buildingBlocks, store]instead ofstore. This eliminates the WeakMap access per call site.The breaking change is that BUILDING_BLOCK functions now accept buildingBlocksContext instead of store as the first parameter.
What was done
