JSONLines 文件

此示例介绍如何从 JSONLines 或 JSONL 文件加载数据。第二个参数是 JSONPointer，用于从文件中每个 JSON 对象中提取属性。每个 JSON 对象在文件中将创建一个文档。

示例 JSONLines 文件

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

示例代码

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.",
  },
]
