DriveChatbot

The Chatbot returns Async Promises.

Chatbot's minimal initalization is like so: chatbot = new langdrive.DriveChatbot({model_config:{HuggingFaceAPIKey:<KEY>}}) or like so: chatbot = new langdrive.Chatbot({model_config:{openAIApiKey:<KEY>}})

Chatbot Example Script

Get started with a sample script by created the following files:

npm install langdrive dotenv
node test.js

.env File:

OPENAI_API_KEY=<YOUR_KEY_HERE>
GOOGLE_DESKTOP_CLIENT_KEYFILE_PATH=<YOUR_KEY_HERE>

test.js File:

require("dotenv").config();
const langdrive = require("langdrive");

// LangDrive returns promises
(async()=>{
  // To initialize Langdrive, give it a model to use and any associated config information.
  // Here we select openAi and pass it an API key (hidden behind .env)
  let chatbot = await new langdrive.DriveChatbot({
    verbose: true,
    drive: {
      verbose: false,
      ...(!GOOGLE_DESKTOP_KEYFILE_PATH
        ? {}
        : {
            server: {
              embed_from_folder: "chatbot",

              // OR
              desktopKeyFile: __dirname + GOOGLE_DESKTOP_KEYFILE_PATH
              // ( Alternately:) desktopKeyFileContents: GOOGLE_DESKTOP_CLIENT_KEYFILE_CONTENTS
              // OR
              // desktopTokenFile: GOOGLE_DESKTOP_CLIENT_TOKEN_PATH:

            }
          })
    },

            openAIApiKey: OPENAI_API_KEY,
            temperature: 0.9
          }
    },
    agent: {
      type: "chat-conversational-react-description",
      memory_length: 2,
      vector_length: 2,
      verbose: false,
      tools: [],
      agent_config: {}
      // prefix
      // suffix
    }
  });
  // LangDrive returns a promise, so let's await those.
  let prompt = "My name is Michael, What can you do for me.";
  console.log("> " , await chatbot.sendMessage(prompt));

  prompt = "What can you do for me in google drive?";
  console.log("> " , await chatbot.sendMessage(prompt));
