Getsnapshot mobx-state-tree



Snapshots don't contain any type information and are stripped from all actions, etc., so they are perfectly suitable for transportation. Central to MST is the concept of a living tree. The tree consists of mutable, but strictly protected objects enriched with run-time type information. In other words; each tree has a shape (type information) and state (data). From this living tree, immutable and structurally shared snapshots are generated automatically. In MobX state tree, the result of serialization is called a ‘snapshot’.
