JSONLines 文件

这个例子演示了如何从 JSONLines 或 JSONL 文件加载数据。第二个参数是一个 JSONPointer，用于从文件中的每个 JSON 对象中提取属性。每个 JSON 对象都将创建一个文档。

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.",

  },

]
