Hi there folks!
I'm creating an app with the help of Langchain and OpenAI. I'm loading my data with JSONLoader and want to store it in a vectorstore, so I can retrieve on user request to answer questions specific to my data. The Langchain docs are describing HNSWLib as a possible store for ONLY Node.js apps.
In my understanding is that NEXT is built up on top of Node.js so it can run SS javascript, so I should be able to use it. I should also mention that the JSONLoader also only works on NodeJS, which works perfectly, so I reckon should be all set.

I've created an API route in app/api/llm/route.ts following the docs of the new Route Handlers, and also installed the hnswlib-nodepackage

import everything I need

export const GET = async (req: NextRequest) => {
  const apiKey = process.env.NEXT_PUBLIC_OPENAI_API_KEY;
  const model = new OpenAI({ openAIApiKey: apiKey, temperature: 0.5, modelName: 'gpt-3.5-turbo' });
  const loader = new JSONLoader(path.join(process.cwd(), '/assets/surfspots.json'));
  const docs = await loader.load();

  const vectorStore = await HNSWLib.fromDocuments(docs, new OpenAIEmbeddings({ openAIApiKey: apiKey }));

  const chain = RetrievalQAChain.fromLLM(model, vectorStore.asRetriever());
  const res = await chain.call({
    query: 'Which is the best longboard wave in Fuerteventura?',
  });
  console.log({ res });
};

which I'm calling on the front-end inside of a client-side react component.

When I'm trying to run this, I get the following error:

error Error: Please install hnswlib-node as a dependency with, e.g. `npm install -S hnswlib-node`
    at HNSWLib.imports (webpack-internal:///(sc_server)/./node_modules/langchain/dist/vectorstores/hnswlib.js:184:19)

Anybody worked with these libraries or have any direction I could consider to debug this?
Thank you in advance!
