Folders with multiple files
===========================

This example goes over how to load data from folders with multiple files. The second argument is a map of file extensions to loader factories. Each file will be passed to the matching loader, and the resulting documents will be concatenated together.

Example folder:

    src/document_loaders/example_data/example/├── example.json├── example.jsonl├── example.txt└── example.csv

Example code:

    import { DirectoryLoader } from "langchain/document_loaders/fs/directory";import {  JSONLoader,  JSONLinesLoader,} from "langchain/document_loaders/fs/json";import { TextLoader } from "langchain/document_loaders/fs/text";import { CSVLoader } from "langchain/document_loaders/fs/csv";const loader = new DirectoryLoader(  "src/document_loaders/example_data/example",  {    ".json": (path) => new JSONLoader(path, "/texts"),    ".jsonl": (path) => new JSONLinesLoader(path, "/html"),    ".txt": (path) => new TextLoader(path),    ".csv": (path) => new CSVLoader(path, "text"),  });const docs = await loader.load();console.log({ docs });
