Integrating OpenAI with Phoenix for Streaming Responses

The article presents a detailed guide on how to use Elixir's Phoenix framework to integrate OpenAI's API into an application. The author explains how to set up the initial environment, perform non-streaming HTTP requests to OpenAI, handle API key authentication, and subsequently parse streaming JSON responses. The article provides code snippets for creating a chat_completion module and parsing the data received from OpenAI. Subsequently, it demonstrates how to properly set up streaming in Phoenix and routes the data as newline-delimited JSON to the clients. The author concludes by highlighting Elixir's effectiveness, exemplifying that less than 70 lines of code were needed to accomplish the streaming task without third-party libraries.
