Storage

Storage in LlamaIndex.TS works automatically once you've configured a StorageContext object.

Local Storage​

You can configure the persistDir and attach it to an index.

import {
  Document,
  VectorStoreIndex,
  storageContextFromDefaults,
} from "llamaindex";

const storageContext = await storageContextFromDefaults({
  persistDir: "./storage",
});

const document = new Document({ text: "Test Text" });
const index = await VectorStoreIndex.fromDocuments([document], {
  storageContext,
});

PostgreSQL Storage​

You can configure the schemaName, tableName, namespace, and connectionString. If a connectionString is not provided, it will use the environment variables PGHOST, PGUSER, PGPASSWORD, PGDATABASE and PGPORT.

import {
  Document,
  VectorStoreIndex,
  PostgresDocumentStore,
  PostgresIndexStore,
  storageContextFromDefaults,
} from "llamaindex";

const storageContext = await storageContextFromDefaults({
  docStore: new PostgresDocumentStore(),
  indexStore: new PostgresIndexStore(),
});

const document = new Document({ text: "Test Text" });
const index = await VectorStoreIndex.fromDocuments([document], {
  storageContext,
});
