This repository contains a range of examples, so you can get up and running easily with Vert.x. 4
Vert.x 3 examples can be found here https://github.com/vert-x3/vertx-examples/tree/3.x
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.
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).
The Vert.x core examples contains a wide range of examples using just Vert.x Core.
Vert.x-Web is a toolkit for building web applications using Vert.x
The Vert.x-Web examples contains a wide range of examples using Vert.x-Web
Vert.x Web Client that provides an easy-to-use web client for Vert.x.
The Vert.x Web Client examples contains a wide range of examples using the Vert.x Web Client
Vertx-Unit is a library for writing asynchronous tests. We include some examples of how to use this tool to test your Vert.x (or other asynchronous) applications.
The Vert.x Unit examples shows how to use Vert.x Unit.
The virtual-threads-examples module shows how to use Vert.x with virtual threads.
The vertx-junit5 modules allow testing Vert.x asynchronous operations with JUnit 5.
Vert.x Opentracing examples contains a wide range of examples using Vert.x Opentracing.
Vert.x Zipkin examples contains a wide range of examples using Vert.x Zipkin.
Vert.x for RxJava provides most of its APIs as RxJava, so you can use those if you prefer.
RxJava is a great choice when you want to perform complex operations on multiple asynchronous streams of data.
The Vert.x RxJava 2 examples contains a wide range of examples using Vert.x for RxJava 2 The Vert.x RxJava 3 examples contains a wide range of examples using Vert.x for RxJava 3
The Vert.x gRPC Examples show how you can implement a gRPC service and invoke a gRPC service with Vert.x.
The Vert.x Kotlin Examples shows a few examples with Kotlin such a REST application, Kotlin coroutines and usage of KotlinTest.
The 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.
