TextNode is the default node type for text. Most common node type in LlamaIndex.TS

Extends

• BaseNode<T>

Extended by

• IndexNode
• Document
• ImageNode

Type Parameters

T

T extends Metadata = Metadata

Constructors

Constructor

new TextNode<T>(init): TextNode<T>

Defined in: packages/core/src/schema/node.ts:227

Parameters

init

TextNodeParams<T> = {}

Returns

TextNode<T>

Overrides

BaseNode.constructor

Properties

id_

id_: string

Defined in: packages/core/src/schema/node.ts:64

The unique ID of the Node/Document. The trailing underscore is here to avoid collisions with the id keyword in Python.

Set to a UUID by default.

toJSON()

toJSON(): Record<string, any>

Defined in: packages/core/src/schema/node.ts:181

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

clone()

clone(): BaseNode

Returns

BaseNode

---

toMutableJSON()

toMutableJSON(): Record<string, any>

Defined in: packages/core/src/schema/node.ts:200

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.

Inherited from

BaseNode.toMutableJSON

---

generateHash()

generateHash(): string

Defined in: packages/core/src/schema/node.ts:247
