Hello, FullStack Vaadin (14-23+) – Practical Solutions

welcome to the ‘FullStack Vaadin (23+) – Practical Solutions’ course. With this course you are going to add a value to your existing JAVA and Vaadin 23+ (with SpringBoot) knowledge by getting familiar with several techniques for solving specifically selected areas of JAVA application development. Each topic involves project configuration section but mostly covers practical solutions being split into several steps.

We will focus on several topics often useful in corporate JAVA development but not exclusively. SpringBoot is being used here as an underlying framework, but solutions presented here are not specific to this platform and can be reused e.g. with recent Quarkus support etc. Java 11 is used in this course (required by Vaadin 23+), but solutions provided here are Java 8 compatible and reusable with legacy applications.

Primary idea of this course is to help existing Vaadin developers to adopt certain knowledge in easy way. Solutions presented are being used for several years in production grade Vaadin applications and libraries used are well known for stability and active development. This will protect the value invested into adopting some libraries or projects.

Topics covered by this course:
During a course we create basic Vaadin single page application and each lecture will add a new enhancement to it. Eventually we create single application with many different features.

  • create a full featured single page application using VAADIN
  • collaboration using server @Push technology
  • export application data in MS Excel format with formatting and some other features
  • export application data in PDF format with formatting, embedded images or bar-codes
  • including MongoDB as persistent data storage
  • using GridFS as an attachment/file uploads data storage

Important part of this course is to realize ‘what we don’t need to do’ when using Vaadin. Simplification can be huge and old saying that ‘the best code is the code you don’t have to write’ proves here.
