Sane Chain

An attempt to make langchainjs easier to work with

WIP - nothing works yet, just saving the name Some things work, just um - not tested, no warranties 🥇

Adds the following loaders:

1. Utility Classes
   1. DocumentLoader
2. Loaders
   1. ChatGPT Loader
   2. Simpler GithubRepoLoader
   3. Roadmap

Utility Classes

DocumentLoader

This class essentially packages up all of langchainjs (plus sanechain) and creates a class: DocumentLoader that can basically load up all your documents regardless of type.

Example:

const filesAndDirectories = [
  'path/to/somefile.md',
  'path/to/somefile.pdf',
  'path/to/somefile.text',
  'path/to/somefile.html',
  'path/to/somedirectory',
  'https://github.com/some/repo',
  'https://github.com/some/other_repo',
  'path/to/chatgpt.json'
]

const documentLoader = new DocumentLoader(filesAndDirectories)
const documents = documentLoader.loadDocuments()
const splitDocuments = documentLoader.splitDocuments()
// Might take time, probably gonna implement a queue system to speed things up, already using async though.
// also @todo add full parity with all langchain python loaders.

Loaders

ChatGPT Loader

import { ChatGPTLoader } from './chat_gpt_loader.js';

const loader = new ChatGPTLoader('path/to/chat/log.json', 10);
const documents = await loader.load();

Simpler GithubRepoLoader

Insert github link, get repo documents.

  import {GithubRepoLoader} from 'sanechain'
  const loader = new GithubRepoLoader("https://github.com/owner/repo", { /*params*/ });
  const documents = await loader.load();
