Document loaders provide a standard interface for reading data from different sources (such as Slack, Notion, or Google Drive) into LangChain’s Document format.
This ensures that data can be handled consistently regardless of the source.
All document loaders implement the BaseLoader interface.
Interface Each document loader may define its own parameters, but they share a common API:
load(): Loads all documents at once.loadAndSplit(): Loads all documents at once and splits them into smaller documents.
import { CSVLoader } from "@langchain/community/document_loaders/fs/csv" ; const loader = new CSVLoader ( ... // <-- Integration specific parameters here ) ; const data = await loader . load () ;
By category LangChain.js categorizes document loaders in two different ways:
File loaders , which load data into LangChain formats from your local filesystem.Web loaders , which load data from remote sources.
