= Vert.x 5 examples
This repository contains a range of examples, so you can get up and running easily with Vert.x. 5
Vert.x 4 examples can be found here https://github.com/vert-x3/vertx-examples/tree/4.x
== The examples
The examples demonstrate how to use all different bits of Vert.x including Vert.x core, Vert.x-Web and various other services and features.
Most of the examples have been written as verticles. For more information on verticles please consult the Vert.x core manual.
Using verticles allows you to scale and run your code from the command line more easily, but if you prefer the same code in the verticles can also be run embedded. It's really up to you. Verticles are entirely optional in Vert.x.
=== Running the examples
==== Running in your IDE
Most of the Java examples can be run directly in your IDE.
We provide a main() method in most of the example classes which allows you to conveniently run them directly in your IDE.
Just right-click the main method or class in your IDE and run as... application (supported by all major IDEs).

=== Mail examples
The link:mail-examples/README.adoc[Vert.x Mail examples] contains a few examples using Vert.x Mail
The mail examples show different ways to create the mail message and send it via
tls, ssl etc. The examples either use localhost:25 to send a mail or use host
mail.example.com. To actually run the examples you will have to change the
mail server and the user credentials in the MailLogin example.
