import { JSONLinesLoader } from "langchain/document_loaders/fs/json";

const loader = new JSONLinesLoader(
  "src/document_loaders/example_data/example.jsonl",
  "/html"
);

const docs = await loader.load();
/*
[
  Document {
    "metadata": {
      "blobType": "application/jsonl+json",
      "line": 1,
      "source": "blob",
    },
    "pageContent": "This is a sentence.",
  },
  Document {
    "metadata": {
      "blobType": "application/jsonl+json",
      "line": 2,
      "source": "blob",
    },
