toJSON()​

toJSON(): Record<string, any>

Called by built in JSON.stringify (see https://javascript.info/json) Properties are read-only as they are not deep-cloned (not necessary for stringification).

Returns​

Record<string, any>

See​

toMutableJSON - use to return a mutable JSON instead

Inherited from​

BaseNode.toJSON

Defined in​

packages/core/dist/schema/index.d.ts:76

toMutableJSON()​

toMutableJSON(): Record<string, any>

Converts the object to a JSON representation. Properties can be safely modified as a deep clone of the properties are created.

Returns​

Record<string, any>

  • The JSON representation of the object.
