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

Source

packages/llamaindex/src/Node.ts:174

---

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.
