Phospho is a powerful and easy-to-use analytics platform for large language model (LLM) applications. It provides developers with the tools to log, analyze, and understand the interactions between users and their LLM applications.

To use Phospho in your Node.js project, install it via npm:

npm install phospho

You need to have a Phospho account to use this library. If you don't have one, you can sign up for free at phospho.ai.

import { phospho } from "phospho";
phospho.init({
  apiKey: "...", // Get your API key on phospho.ai
  projectId: "...",
});
// Log a task
phospho
  .log({ input: "User Query", output: "LLM Response" })
  .then((response) => console.log("Log successful:", response))
  .catch((error) => console.error("Error:", error));

You only need to do phospho.init() once in your app, then you can reuse it accross you whole codebase.
