# Dify Node.js SDK

This is the Node.js SDK for the Dify API, which allows you to easily integrate Dify into your Node.js applications.

## Install

```bash
npm install dify-client
```

## Usage

After installing the SDK, you can use it in your project like this:

```js
import { DifyClient, ChatClient, CompletionClient } from 'dify-client'

const API_KEY = 'your-api-key-here'
const user = `random-user-id`
const query = 'Please tell me a short story in 10 words or less.'
const remote_url_files = [{
    type: 'image',
    transfer_method: 'remote_url',
    url: 'your_url_address'
}]

// Create a completion client
const completionClient = new CompletionClient(API_KEY)
// Create a completion message
completionClient.createCompletionMessage({'query': query}, user)
// Create a completion message with vision model
completionClient.createCompletionMessage({'query': 'Describe the picture.'}, user, false, remote_url_files)

// Create a chat client
const chatClient = new ChatClient(API_KEY)
// Create a chat message in stream mode
const response = await chatClient.createChatMessage({}, query, user, true, null)
const stream = response.data;
stream.on('data', data => {
    console.log(data);
});
stream.on('end', () => {
    console.log('stream done');
});
// Create a chat message with vision model
chatClient.createChatMessage({}, 'Describe the picture.', user, false, null, remote_url_files)
// Fetch conversations
chatClient.getConversations(user)
// Fetch conversation messages
chatClient.getConversationMessages(conversationId, user)
// Rename conversation
chatClient.renameConversation(conversationId, name, user)


const client = new DifyClient(API_KEY)
// Fetch application parameters
client.getApplicationParameters(user)
// Provide feedback for a message
client.messageFeedback(messageId, rating, user)

```

Replace 'your-api-key-here' with your actual Dify API key.Replace 'your-app-id-here' with your actual Dify APP ID.
