CharacterTextSplitter

Besides the RecursiveCharacterTextSplitter, there is also the more standard CharacterTextSplitter. This splits only on one type of character (defaults to "\n\n"). You can use it in the exact same way.

import { Document } from "langchain/document";
import { CharacterTextSplitter } from "langchain/text_splitter";

const text = "foo bar baz 123";
const splitter = new CharacterTextSplitter({
  separator: " ",
  chunkSize: 7,
  chunkOverlap: 3,
});
const output = await splitter.createDocuments([text]);
