## What it is
LuaSocket is a Lua extension library providing TCP and UDP transport support via C modules, plus Lua modules for common Internet protocols like SMTP, HTTP, and FTP. It also includes utility modules for MIME encoding, URL manipulation, and LTN12 filters, sinks, and sources.

## Use cases
- make http requests from lua
- send email via smtp in lua
- upload and download files over ftp
- open tcp and udp sockets in lua
- encode and decode mime in lua
- parse and build urls in lua

## When to choose
- you need low-level TCP/UDP networking in a Lua application
- you want simple HTTP, SMTP, or FTP client functionality in Lua
- you need a mature, MIT-licensed networking library compatible with Lua 5.1 through 5.4

## When to avoid
- you need asynchronous or high-concurrency networking with an event loop
- you need modern TLS/HTTPS support out of the box
- you are not working in the Lua ecosystem

## Facets
- artifact type: library
- maturity: stable
- function: http-client, networking, email, websocket
- domain: networking, developer-tools, web-development
- platform: lua, cross-platform, windows
- tags: tcp, udp, smtp, ftp, mime, url, lua-extension, linux, macos
