Vaadin
Vaadin (Finnish pronunciation: [ˈʋɑːdin]) is an open-source web application development platform for Java. Vaadin includes a set of Web Components, a Java web framework, and a set of tools that enable developers to implement modern web graphical user interfaces (GUI) using the Java programming language only (instead of HTML and JavaScript), TypeScript only, or a combination of both.
Development was first started as an adapter on top of the Millstone 3 open-source web framework released in the year 2002. It introduced an Ajax-based client communication and rendering engine. During 2006 this concept was then developed separately as a commercial product. As a consequence of this, a large part of Vaadin's server-side API is still compatible with Millstone's Swing-like APIs.
In early 2007 the product name was changed to IT Mill Toolkit and version 4 was released. It used a proprietary JavaScript Ajax-implementation for the client-side rendering, which made it rather complicated to implement new widgets. By the end of the year 2007 the proprietary client-side implementation was abandoned and GWT was integrated on top of the server-side components. At the same time, the product license was changed to the open source Apache License 2.0. The first production-ready release of IT Mill Toolkit 5 was made on March 4, 2009, after an over one year beta period.
On September 11, 2008, it was publicly announced that Michael Widenius–the main author of the original version of MySQL–invested in IT Mill, the Finnish developer of Vaadin. The size of the investment is undisclosed.
On May 20, 2009, IT Mill Toolkit changed its name to Vaadin Framework. The name originates from the Finnish word for doe, more precisely put, a female reindeer. It can also be translated from Finnish as "I insist". In addition to the name change, a pre-release of version 6 along with a community website was launched. Later, IT Mill Ltd, the company behind the open source Vaadin Framework, changed its name to Vaadin Ltd.
On March 30, 2010, Vaadin Directory was opened. It added a channel for distributing add-on components to the core Vaadin Framework, both for free or commercially. On launch date, there were 95 add-ons already available for download.
Vaadin Flow (formerly Vaadin Framework) is a Java web framework for building web applications and websites. Vaadin Flow's programming model allows developers to use Java as the programming language for implementing User Interfaces (UIs) without having to directly use HTML or JavaScript. Vaadin Flow features a server-side architecture which means that most of the UI logic runs securely on the server reducing the exposure to attackers. On the client-side, Vaadin Flow is built on top of Web Component standards. The client/server communication is automatically handled through WebSocket or HTTP with light JSON messages that update both, the UI in the browser and the UI state in the server.
Vaadin Flow's Java API includes classes such as TextField, Button, ComboBox, Grid, and many others that can be configured, styled, and added into layout objects instances of classes such as VerticalLayout, HorizontalLayout, SplitLayout, and others. Behaviour is implemented by adding listeners to events such as clicks, input value changes, and others. Views are created by custom Java classes that implement another UI component (custom or provided by the framework). This view classes are annotated with @Route to expose them to the browser with a specific URL. The following example illustrates these concepts:
