Using the Helicone SDK (recommended)

​
Walkthrough: logging chat completions

1

To get started, install the `@helicone/helicone` package

npm install @helicone/helicone
2

Setup the logger

  import { HeliconeManualLogger } from "@helicone/helicone";

  const logger = new HeliconeManualLogger({
    apiKey: process.env.HELICONE_API_KEY
  });
3

Register the request and call your LLM

const reqBody = {
  "model": "phi3:mini",
  "messages": [{
  "role": "user",
    "content": "Why is the sky blue?"
  }],
  "stream": false
}

logger.registerRequest(reqBody);

const r = await fetch("http://localhost:11434/api/chat", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
  },
  body: JSON.stringify(reqBody)
})
4

Decode and send the logs!

  const res = await r.json();
  console.log(res);
  logger.sendLog(res);
5

Go to the Helicone Requests pgae and see your request!

​
Example: logging completion request

The above example uses phi3:mini model and the Chat Completion interface. The same can be done with a regular completion request:

// ...
const reqBody = {
  model: "llama3.1",
  prompt: "Why is the sky blue?",
  stream: false,
};

logger.registerRequest(reqBody);

const r = await fetch("http://localhost:11434/api/generate", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
  },
  body: JSON.stringify(reqBody),
});

logger.sendLog(res);
