• Works in both browser and Node.js environments

Installation

npm install dwk-sse-client

Or include directly in browser:

<script src="https://unpkg.com/dwk-sse-client/dist/index.js"></script>

Usage

Browser Example

<script>
  const deepseek = new DWKSSEClient({
    baseUrl: 'https://your-api-url.com',
    jwt: 'your.jwt.token.here',
    dwk_token: 'your.dwk.token.here'
  });

  // 设置错误处理
  deepseek.onError = (error) => {
    console.error('Error:', error.message);
    if (error.code) {
      console.error('Error code:', error.code);
    }
    if (error.innerExceptions) {
      console.error('Inner exceptions:', error.innerExceptions);
    }
  };

  // Start streaming
  const stream = deepseek.stream('Your prompt here');

  // Handle responses
  for await (const chunk of stream) {
    if (chunk.code === '200') {
      console.log(chunk.data);
    } else {
      console.error(chunk.message);
    }
  }

  // To abort
  deepseek.abort();
</script>

Node.js Example

const { DWKSSEClient } = require('deepseek-stream');

const deepseek = new DWKSSEClient({
  baseUrl: 'https://your-api-url.com',
  jwt: 'your.jwt.token.here',
  dwk_token: 'your.dwk.token.here'
});

// 设置错误处理
deepseek.onError = (error) => {
  console.error('Error:', error.message);
  if (error.code) {
    console.error('Error code:', error.code);
  }
  if (error.innerExceptions) {
    console.error('Inner exceptions:', error.innerExceptions);
  }
};

async function run() {
  const stream = deepseek.stream('Your prompt here');
  
  for await (const chunk of stream) {
    if (chunk.code === '200') {
      process.stdout.write(chunk.data);
    } else {
      console.error(chunk.message);
      break;
    }
  }
}

run();

API

new DWKSSEClient(options)

Constructor options:

• baseUrl: Base API URL (required)
• jwt: JWT token for authentication (optional)
• dwk_token: DWK token for authentication (optional)
• systemPrompt: System prompt for API (optional, default: 'You are a helpful assistant')

Methods

stream(prompt: string): AsyncGenerator<DWKSSEResponse>

Starts a streaming request with the given prompt.

abort(): void

Aborts the current streaming request.

Error Handling

The client provides detailed error information through the onError callback:

client.onError = (error) => {
  console.error('Error:', error.message);
  if (error.code) {
    console.error('Error code:', error.code);
  }
  if (error.innerExceptions) {
    console.error('Inner exceptions:', error.innerExceptions);
  }
};

The error object contains:

• message: The error message
• code: The error code from the server
• innerExceptions: Array of inner business exceptions (if any)
