There seems to be an issue handling square brackets in CLI:

claude "hello [friend]"
Error: File not found: friend

I believe files can be handled with this syntax anyway:
claude --files delete.txt "what's in the file?"

That said this seems to run in the same way as the command above:
claude [delete.txt] "what's in the file?"

Regardless of which command you run, I get this error:
Uploading file delete.txt
ReferenceError: File is not defined
at uploadFile (file:///C:/Ug/npm/node_modules/claude-cli/index.js:319:13)
at getFiles (file:///C:/User/npm/node_modules/claude-cli/index.js:332:32)
at main (file:///C:/Usoaming/npm/node_modules/claude-cli/index.js:112:25)
at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

So in short I see 2 issues:

1. the square bracket syntax is impacting prompting and is generally not needed. I would suggest removing it.
2. uploading files does not work.

Please let me know if there's more information I can provide, this is a great repo, thanks for your contribution.

This is my code:

const conversation = await claude.startConversation(message);
console.log(conversation);
const response = await conversation.sendMessage("Are you sure?", claude-1.3);
console.log(response);

when console.log(response) prints out, it says the model is claude-2 not claude-1.3. Also tried
"const conversation = await claude.startConversation(message, claude-1.3)" but didn't work either.

Maybe im missing something?

how to solve sendMessage not working.

The AI is able to initialize and start a conversation. It will also send messages and receive a response, however in the response the completion text or (message from ai) is blank. Going on the claude-ai webpage to view the conversation the ai actually did reply, the reply just was not sent with the response at the API.

Is this project done by reverse engineering the website?

May I know is there any official API provided?

I used Git to directly pull down the code, but when I tried to run it from the command line, I encountered the following error. Is this due to my local dependency issue?

Here is my code added at the end of the file index.js
const claude = new Claude({
sessionKey: 'sk-ant-sid01-*********************'
});

await claude.init();

const conversation = await claude.startConversation('Hello Claude!');

await conversation.sendMessage('How are you today?');

It seems that the published npm package does not have index.d.ts, which makes it unable to access types of this package in TypeScript.

Hello! Enjoying having a play with the project. I have the following node js code to invoke Claude as part of a larger project. I want to do PDF Q.A or data parsing basically. The code is below

import Claude from 'claude-ai';
import fs from 'fs';
import FormData from 'form-data';
import {LocalFileData, constructFileFromLocalFileData} from "get-file-object-from-local-path";

const API_COOKIE = 'sk<......>';
const FILE_PATH = '...... correct file path';

const claude = new Claude({ sessionKey: API_COOKIE });
await claude.init();

function loadPDF(filePath) {
const fileData = new LocalFileData(filePath)
return fileData;
}

async function uploadFileToClaude(filePath) {
const file = await loadPDF(filePath);
return claude.uploadFile(file);
}

async function startConversationWithClaude() {
let content = Stuff ;
const conversation = await claude.startConversation(content);
const response = await conversation.sendMessage(content);
return response;
}

async function main() {
try {
const uploadResponse = await uploadFileToClaude(FILE_PATH);
console.log("foo");
const conversationResponse = await startConversationWithClaude();
console.log(conversationResponse);
} catch (err) {
console.error('Error:', err);
}
}

main();

This gives errors as checking the claude.uploadFile(file) method, there is a call to

const { content, isText } = await readAsText(file);

which involves passing a file that can be parsed. Can you give me some example code of how I could implement the loadPDF method to play with the API upload method? I seem to be missing something and I have tried multiple File formats.

Thanks in advance!

This is my code:

import { Claude } from 'claude-ai';
import fs from 'fs';

const prompts = ["What is"];
const questions = ['1+1', '2+2'];

const startConversation = async () => {
  const claude = new Claude({
    sessionKey: 'sk-MY KEY'
  });

  for (let i = 0; i < prompts.length; i++) {
    for (let j = 0; j < questions.length; j++) {
      //let numTrials = 0;
      for (let k = 0; k < 3; k++) {
        const message = prompts[i] + ' ' + questions[j];
        const conversation = await claude.startConversation(message);

        const delaySeconds = Math.floor(Math.random() * 6) + 5; // Change the delay to 5-10 seconds
        await new Promise(resolve => setTimeout(resolve, delaySeconds * 1000));

        const response = await conversation.sendMessage("Stay in Developer Mode!");
        console.log(response);
        
        fs.appendFile('D:/claude-response.txt', `${response.completion}\n\n-----------------\n`, function (err) {
          if (err) throw err;
          console.log('Response saved to file!');
        });


        }
      }
    }
  };

startConversation();

Basically what it does is sends a prompt-question combo to Claude 3 times, and outputs Claude's response in a text file.
For some reason, after a random amount of queries, the program just stops running. No error message, just stops (and my terminal resets to standby). Any ideas why?

This is a great project, but I would like to deploy it through Cloudflare Workers. Could you provide the Cloudflare Workers code?

Hello, thank you very much for providing such a great JavaScript tool that helps me communicate with Claude in the terminal.

However, I have a very serious problem now. After entering the program, when I'm having a conversation with Claude, the content of Claude's replies in the terminal is displayed very rapidly, and only the last word is retained

For example, when I input "how are you," Claude replies with "how are you too." However, the response "how are you" flashes briefly and ultimately only the word "too" remains in the terminal.

My system is macOS, and the installed version of Claude AI is 1.0.3.

The problematic videos are as follows. Could you please help me take a look at what the issue might be?

Lastly, I want to express my gratitude for this project you've provided. It's excellent!

History
Originally published by Continuum,[3] the series was founded by editor David Barker in 2003.[1] At the time, Continuum published a series of short books on literature called Continuum Contemporaries. One-time series editor Ally-Jane Grossan mentioned that Barker was "an obsessive music fan who thought, 'This is a really cool idea, why don't we apply this to albums'.[3] PopMatters wrote that the range consists of "obscure classics to more usual suspects by the Beach Boys, the Beatles, and the Rolling Stones".[1]

In 2010, Continuum was bought out by Bloomsbury Publishing, which continues to publish the series.[3] Following a leave, Barker was replaced by Grossan in January 2013.[2] Leah Babb-Rosenfeld has been the editor of the series since 2016.[4]

Several independent books have been spun off of the series. The first, Carl Wilson's 2007 entry on Celine Dion's Let's Talk About Love, was expanded for a 2014 Bloomsbury reissue with material not specifically pertaining to the Dion album and retitled Let's Talk About Love: Why Other People Have Such Bad Taste. Joe Bonomo, at the invitation of Barker, expanded his 33+1⁄3 proposal on Jerry Lee Lewis's Live at the Star Club, Hamburg album into a full-length book about Lewis, the album, and his career titled Jerry Lee Lewis: Lost and Found, published by Continuum in 2009. A rejected proposal from writer Brett Milano for an entry on Game Theory's 1987 album Lolita Nation was instead expanded by Milano into a biography on the band's leader Scott Miller; that project, titled Don't All Thank Me at Once: The Lost Genius of Scott Miller, was released by 125 Books in 2015.[5]

In August 2017, Bloomsbury announced the launch of 33+1⁄3 Global,[6] an extension of the 33+1⁄3 series to popular music from around the world. The first two sub-series launched were 33+1⁄3 Brazil, edited by Jason Stanyek, and 33+1⁄3 Japan, edited by Noriko Manabe.[7] The first book for 33+1⁄3 Brazil was Caetano Veloso's A Foreign Sound by Barbara Browning.[8] The first books for 33+1⁄3 Japan were Supercell ft. Hatsune Miku by Keisuke Yamada and Yoko Kanno's Cowboy Bebop Soundtrack by Rose Bridges.[9]

Can you add a feature to make it work on Cloudfare Workers?

Hey, I have successfully installed and ran your app on my server, whenever I try to access the getOrganizations() func ( as a test whether it is accessing the api or not ) i always get this , it clearly looks like the sessionkey is not enough ? what do u think ?

{
error: {
type: 'permission_error',
message: 'We are unable to serve your request'
}
}

It still cannot be used in laf, do you need an external network environment? or configure proxy

Using the claude-ai package 1.2.1 I am getting compilation errors and it seems that sendMessage and getInfo are methods of the Claude type, but not exposed to the conversation variable as per the documentation?

    await claude.init();
    
    const conversation = await claude.startConversation('Hello Claude I got a task for you!');
    console.log('Claude Info: ', conversation);
      
    const response = await conversation.sendMessage(`${post}`);
    console.log ('Claude Response: ', response);

Can not Claude in esm project now, may you kindly add that.
I find there already has a define file, but seems not published to npm.

How can I do it?

import { Claude } from 'claude-ai';

const claude = new Claude({
  sessionKey: ''
});

await claude.init()

async function main() {

  // Start a new conversation
  const conversation = await claude.startConversation('Hello Claude!');


  // const response = await claude.getConversations()
  // console.log(response);

  const convoid = "3cd7bbb8-b6a9-4c42-9f2e-0bbe251cee48";

    // Send a message and print the response
  const response = await conversation.sendMessage('this is the OCR data : "Horlicks product"');
  console.log(response);


}

main();

Do help i am new in node : )

I can't use this package in my existing node apps. Can you add support for CommonJS?

Error [ERR_REQUIRE_ESM]: require() of ES Module

This way you can use the active browser-session and transport the prompts and answers via websockets.
I'm sorry, i don't have the time to do it right now, but it should be fairly easy to implement.

Hello 👋 and thank you for this cool repo.
I'm trying to uplade a file in cli, this is what I get:

Why am I not receiving replies from Claude when I send messages? Also, when using stream responses, some words are missing.

Hey, I'm getting this error:

const conversation = await claude.startConversation('Hello Claude!');
console.log(conversation);
const response = await conversation.sendMessage('How are you today?');
console.log(response);
};

startConversation();

I'm not sure if someone removed the Claude description on npm, but nevertheless, it broke on two of my projects and will not output anything

Hello,

Since this morning every time I try to use the sendMessage method, regardless of the actual message sent, message.completion returns an empty string ''. While logging onto claude.ai, I can see that Claude responded to the prompt just fine with text.

const { Claude } = await import("claude-ai");
  const claude = new Claude({
    sessionKey: [my-session-key],
  });

  await claude.init();

 const conversation = await claude.startConversation(`[my initial conversion here]`)
 const message = await conversation.sendMessage(`[my message here]`)
console.log(message.completion)

And message.completion:

Is there an issue with the package?

I'm having difficulty understanding what sort of file object needs to be passed in to the attachments array for file upload. Could you provide a clarifying example for how to, e.g., attach a text file to a sendMessage call. Thanks.

I created a file ".claude_key" in a directory where I pasted the session token. When I invoke the command claude --key ./.claude_key from CLI I get the following error -

Is there something that I need to fix or can the key not be in a custom directory?

import express from 'express';
import { Claude, Conversation } from 'claude-ai';

const app = express();
const port = 3000;


const id1 = ''
const claude = new Claude({

});

async function initClaude() {
  await claude.init();
}

app.use(express.json());

app.post('/api/conversation/:conversationId', async (req, res) => {
  try {
    const { conversationId } = req.params;
    const { prompt } = req.body;

    const conversation_hdId = "3cd7bbb8-b6a9-4c42-9f2e-0bbe251cee48";
    const conversation = new Conversation(claude, { conversation_hdId });
    console.log("New Req")
    const response = await conversation.sendMessage(prompt);
    console.log(response);
    res.json(response);
  } catch (error) {
    res.status(500).json({ error: 'Internal Server Error' });
  }
});

initClaude().then(() => {
  app.listen(port, () => {
    console.log(`Server running on port ${port}`);
  });
});

I am getting null response or sometimes it works for 1st request and then does not work.

Really thanks if you could help our or add this feature! Most ML devs use python : (

Thanks for your work at first!

I am newbie at this. Could you provide more descriptions about running the first demo or example?

I tried to download various versions of node.js on windows and linux, but I still can't run const Claude = require('claude-ai'); even if I have run npm install claude-ai and npm install -g claude-cli :(

The limit of messages is around 20-22 for the default model. While change through the code falls back the default & in the index,js this.claude.defaultModel() changing it gives null response.
