Attempted import error: 'PGVectorStore' is not exported from 'llamaindex' (imported as 'PGVectorStore').

[Djmcflush]

Describe the bug
When attempting to import PGVectorStore from the llamaindex package in a Next.js project, an error occurs indicating that PGVectorStore is not exported from llamaindex. I have tried various Node.js versions (v18 and v20) using nvm, and this issue persists across the last 8 releases of llamaindex. The bug blocks the ability to use PGVectorStore despite it being referenced in other examples and documentation.

To Reproduce
Code to reproduce the behavior:

import { PGVectorStore } from 'llamaindex';

// Expected behavior: no import error and successful instantiation of PGVectorStore
// Actual behavior: "Attempted import error: 'PGVectorStore' is not exported from 'llamaindex'"

Expected behavior
I expected PGVectorStore to be exported from llamaindex, allowing it to be imported and used as part of my Next.js project, as referenced in example code found in the documentation.

Desktop (please complete the following information):

• OS: macOS Ventura 13.4.1
• JS Runtime / Framework / Bundler (select all applicable)
  • Node.js
  • Deno
  • Bun
  • Next.js
  • ESBuild
  • Rollup
  • Webpack
  • Turbopack

  • Edge Runtime
  • AWS Lambda
  • Cloudflare Worker
  • Others (please elaborate on this)
• Version: Node v18.20.4 and v20 (via nvm), Next.js v13.4.5

Additional context
I have tested this on both Node.js v18 and v20 (using nvm) across multiple releases of llamaindex (the last 8 versions). The error persists regardless of the version, preventing usage of PGVectorStore. I have also explored submodule imports, but none of them work. Other vector stores like PostgresDocumentStore work fine, but I specifically need the functionality provided by PGVectorStore.

This is expected behavior, please import from llamaindex/vector-store/PGVector ….

I cannot expose it to top level at this time, but will work to fix this by decouple modules in this week

@Djmcflush as @himself65 mentions you better should use import { PGVectorStore } from "llamaindex/vector-store" as we don't export vector stores to root for edge run-times.

We're moving now the vector store implementations to each package to avoid confusion, see #1587

closing this for now

[marcusschiesser]

sorry, we'll keep it open to update the documentation

[marcusschiesser]

@himself65 I think we should then also remove

LlamaIndexTS/packages/llamaindex/src/index.ts

Line 19 in d6c270e

export * from "./vector-store.js";

to avoid further confusion between edge and nodejs runtime
