The author will guide readers through building a production-ready chat application using Go, starting with setting up a local machine and using ngrok for testing and deployment. The application will be built with Golang for the backend server functions and JavaScript and HTML for the frontend. The chat app's UI will display messages fetched from a JSON file, allowing users to send and receive messages in real-time. After testing on a local machine, ngrok will be used to deploy the app online, providing a publicly accessible URL that can be shared with others. The next part of the series will focus on adding a better classier UI, security, and user tracking functionality to the chat app.
