This repository includes ready-to-use Lua modules, tools, Lua scripts, and Lua Server Pages (LSP) examples intended to be dropped directly into real applications or used as practical reference material. The examples span common web and device use cases such as form handling, REST services, AJAX and WebSocket interaction, authentication and session management, database access, IoT messaging, and embedded-specific workflows used with the Barracuda App Server, Mako Server, and Xedge-based systems.

Most of the examples include hidden files and/or directories. With the Barracuda App Server, resources starting with a dot are hidden and cannot be accessed by an HTTP client such as a browser. The resources can only be accessed on the server side. To make sure you see all resources, use the Linux command: ls -a
