Tutorial on File Uploads with Req and Multipart Libraries in Elixir

Source: samrat.me

Samrat Man Singh shares a neat trick on how to manage file uploads in Elixir using the Req library, which doesn’t natively support file uploads. Instead, he uses the Multipart library to construct the HTTP request. He provides a specific example where an mp3 file is sent to the OpenAI audio transcription API (Whisper). The example code involves reading the file, constructing the multipart form data, setting proper headers including authorization, and sending the request using the Req library.
