= Vert.x 4 examples



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



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).



=== Vert.x core examples



The link:core-examples/README.adoc[Vert.x core examples] contains a wide range of examples using just Vert.x Core.



=== Vert.x-Web examples



Vert.x-Web is a toolkit for building web applications using Vert.x



The link:web-examples/README.adoc[Vert.x-Web examples] contains a wide range of examples using Vert.x-Web



=== Vert.x Web Client examples



Vert.x Web Client that provides an easy-to-use web client for Vert.x.



The link:web-client-examples/README.adoc[Vert.x Web Client examples] contains a wide range of examples using the Vert.x Web Client



=== Vertx Unit examples



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 link:unit-examples/README.adoc[Vert.x Unit examples] shows how to use Vert.x Unit.



=== Virtual Threads



The `virtual-threads-examples` module shows how to use Vert.x with virtual threads.



See link:virtual-threads-examples/README.adoc[Vert.x Virtual Threads 5 examples].



=== Vert.x JUnit 5 examples



The `vertx-junit5` modules allow testing Vert.x asynchronous operations with JUnit 5.



See link:junit5-examples/README.adoc[Vert.x JUnit 5 examples].



=== Vert.x Opentracing examples



link:opentracing-examples/README.adoc[Vert.x Opentracing examples] contains a wide range of examples using Vert.x Opentracing.



=== Vert.x Zipkin examples



link:zipkin-examples/README.adoc[Vert.x Zipkin examples] contains a wide range of examples using Vert.x Zipkin.



=== RxJava examples



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 link:rxjava-2-examples/README.adoc[Vert.x RxJava 2] examples contains a wide range of examples using Vert.x for RxJava 2

The link:rxjava-3-examples/README.adoc[Vert.x RxJava 3] examples contains a wide range of examples using Vert.x for RxJava 3



=== gRPC examples



The link:grpc-examples/README.adoc[Vert.x gRPC Examples] show how you can implement a gRPC service and invoke a gRPC service with Vert.x.



=== Kotlin examples



The link:kotlin-examples/README.adoc[Vert.x Kotlin Examples] shows a few examples with Kotlin such a REST application,

Kotlin coroutines and usage of https://github.com/kotlintest/kotlintest[KotlinTest].



=== 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.



=== Service Proxy Examples



The link:service-proxy-examples/README.adoc[Vert.x Service Proxy examples] contains an example of service proxy usage.

It depicts how a service provider can be implemented and how the published service can be consumed.



=== Spring Examples



The link:spring-examples/README.adoc[Vert.x Spring Examples] shows how vert.x application can be integrated inside a Spring

ecosystem.



=== Redis example



The link:redis-examples/README.adoc[Vert.x Redis Example] shows how you can interact with Redis using the vert.x Redis client.



=== Mongo example



The link:mongo-examples/README.adoc[Vert.x Mongo Example] shows how you can interact with MongoDB using the vert.x Mongo client.



=== SQL client example



The link:sql-client-examples/README.adoc[Vert.x SQL Client Examples] shows how you can interact PostgreSQL or MySQL Databases using the Reactive SQL client.



=== Kafka example



The link:kafka-examples/README.adoc[Vert.x Kafka Examples] shows how you can interact Kafka using the vert.x Kafka

client.

=== Service Proxy Examples



The link:service-proxy-examples/README.adoc[Vert.x Service Proxy examples] contains an example of service proxy usage.

It depicts how a service provider can be implemented and how the published service can be consumed.



=== JPMS examples



This link:jpms-examples/README.adoc[JPMS examples] shows how a simple Java (11) modular application using Vert.x as automatic modules.



=== HTTP/2 Showcase
