Clement Escoffier

Who am I? That’s a good question. I had several professional lives, from academic positions to management. Currently, I’m working for Red Hat as Vert.x core developer. I have been involved in projects and products touching many domains and technologies such as OSGi, mobile app development, continuous delivery, DevOps… My main point of interest? Software engineering, so processes, methods, tools that make the development of software more efficient and also more fun. I’m also an active contributor to many open source projects such as Apache Felix, iPOJO, Wisdom Framework, and obviously, Eclipse Vert.x.

Continuously Building a Book

I’m thrilled to announce the availability of a mini-book about Eclipse Vert.x. This book focuses on the development of reactive microservices in Java and covers reactive systems and reactive programming.

Writing a book, even for a mini-book is a tough task. While writing code and writing a book are very different experiences, you can apply the same process and good practice. I would like to list a couple of tips I’ve used to make the writing a bit easier.

Eclipse Vert.x Core Cheat Sheet

Eclipse Vert.x is a toolkit used to build reactive and distributed systems on the Java Virtual Machine. Vert.x supports a variety of languages letting you choose which one you’d prefer. The Vert.x Core cheat sheet covers the creation of a project using Apache Maven, Gradle or the Vert.x CLI, and references most common Vert.x Core APIs, in 3 different languages (Java, JavaScript, and Groovy). Forgot how to create an HTTP server, use the HTTP client, implement a request-response on the event bus?  Just check the cheat sheet. Together with the Red Hat Developer Team, I’ve put together this handy cheat sheet – hopefully, you’ll find it useful too!
