Can you do function calls with streaming enabled in node?

Hi @worldly garden. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Yes, you can perform function calls with streaming enabled. However, it requires careful handling of the streamed responses and the function calls. Here's a general approach based on the information from the OpenAI community forum:

  1. Enable streaming in your API call by setting stream: true.

  2. As the responses come in chunks, you need to handle each chunk separately. If a chunk contains a function call, you need to process it accordingly.

  3. For each function call, extract the function name and arguments. Check if the function exists in your available functions, and if it does, call the function with the provided arguments.

  4. After processing the function call, you can feed the function output back to the chat.

Here's a simplified example of how you might handle the chunks and function calls:

// Example tool definitions
const tools = {
  'order-single-item': (args) => {
    // Logic to handle a single item order
    console.log('Ordering Single Item:', args);
    // Implement the ordering logic here
  },
  'order-menu-item': (args) => {
    // Logic to handle a menu item order
    console.log('Ordering Menu Item:', args);
    // Implement the ordering logic here
  },
  'order-drink-item': (args) => {
    // Logic to handle a drink item order
    console.log('Ordering Drink Item:', args);
    // Implement the ordering logic here
  },
};

// Assume `stream` is the stream of responses from the API
for (let chunk of stream) {
  if (chunk.choices[0].delta.tool_calls) {
    for (let tc of chunk.choices[0].delta.tool_calls) {
      if (tc.function.name in tools) {
        tools**tc.function.name** (tc.function.arguments);
      }
    }
  }
}

Please note that this is a simplified example and the actual implementation may vary based on your specific use case and the structure of the responses from the API.
