JSONLines files

This example goes over how to load data from JSONLines or JSONL files. The second argument is a JSONPointer to the property to extract from each JSON object in the file. One document will be created for each JSON object in the file.

Example JSONLines file:

{"html": "This is a sentence."}
{"html": "This is another sentence."}

Example code:

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",
},
"pageContent": "This is another sentence.",
},
]
