What is this?
Vert.x Core is a toolkit for building reactive, event-driven applications on the JVM, providing low-level support for HTTP, TCP, file system access, and more.

Many higher-level Vert.x components are built on top of this core module.

It provides built-in support for HTTP (including HTTP/2), TCP, UDP, and file system access, built on top of Netty's non-blocking I/O.Why would I use Vert.x instead of writing raw Netty code?Vert.x wraps Netty with a higher-level, event-driven API (the Vert.x event loop model) so you get reactive, non-blocking networking without managing Netty's lower-level details directly, while still being usable by other Vert.x ecosystem components built on top of it.
