Data-Star is a tool that allows for real-time progress bar updates in GoLang using SSE (Server-Sent Events).With Data-Star, developers can easily provide users with real-time feedback on what is happening during heavy on-demand jobs.Data-Star leverages SSE to send updates to the frontend, allowing users to see the progress of the ongoing task.By using SSE with Data-Star, each request can respond with an N events stream in real-time, enabling continuous progress updates for the user.
