Fighting for simplicity with end-to-end ownership

#168体彩开奖官网计划现场结果直播查询 #澳洲5官方开奖结果体彩 #手机app看澳洲5开奖现场直播视频 Full-stack way of thinking

We believe that a full-stack approach is the most productive way of crafting high-quality applications: A development team should own a feature from the back-end to the front-end, rather than dividing tasks between separate front-end and back-end teams. By avoiding communication barriers, a team can iterate drastically faster - not only shipping faster, but also with better quality.


The chosen software stack should align with this organization structure: reducing complexity through a unified full-stack framework.

PRODUCTIVITY
CONTROL

Flow

Components
Flow
Spring Boot
Vaadin Flow boosts developer productivity for web apps with Spring backends. Write UIs with Vaadin components in 100% Java, no JS or HTML. Vaadin handles rendering, events and comms.

Hilla

Components
React
Hilla
Spring Boot
Vaadin Hilla connects React with a Spring backend, automating comms and generating TypeScript APIs for Java services. It also fully integrates Vaadin's powerful UI components with React.

Next.js

Components
React
Next.js
Node.js
Vaadin suits teams using Java backends, while Next.js is popular for those using TypeScript on Node.js. Next.js enables frontend teams to become full-stack by expanding into backend services.

Decoupled

Components
React or Angular
REST or GraphQL
Backend of choice
A fully decoupled stack requires choosing technologies for each layer. This may be preferred by organizations with separate backend and frontend teams, or when control over layers is limited.
Secure by default
Vaadin secures and automates all communication between the browser and server. Safeguards like automated session keys, input type checking, and server-side validation are on by default. Support for Spring Security and optional SSO simplify building security on all levels of your app.
Batteries included
Vaadin is a complete platform that works out of the box. It includes web frameworks, UI components, a Figma-based design system, and tools for building and testing UIs. It speeds up development and scales easily, ensuring well-tested and integrated dependencies you can build on.
Real-time communication
Vaadin enables real-time communication, pushing UI updates and feeding data-hungry UIs from the backend through websockets and lazy loading. Built-in features allow for functionality like Google Docs-style multiplayer editing, enhancing real-time user collaboration.
Vaadin UI Components

Powerful UI Components are the foundation for a great UX

Accessible , Beautiful, Consistent

Optimize developer productivity by building from a set of feature rich web components built-in to Vaadin. They are optimized for data heavy business applications and include API for both Java or with React.

Based on web standards
Based on the open W3C Web Components standard, ensuring that they work natively in all modern browsers and can be used with virtually any front-end framework.
Accessible
Vaadin components work with screen readers and assistive devices so everyone can use your app. Conforms to the WCAG 2.1 AA standard, and EU and US accessibility regulations.
Themable
Easy theming through a set of global CSS properties. Additionally, a powerful CSS injection mechanism is available for advanced custom styling.
Figma library
The high quality, high fidelity Figma library makes it easy to create mockups and prototypes of Vaadin-based UIs.
Java and Typescript APIs
Use Java APIs with Vaadin Flow, or TypeScript APIs with Hilla and other front-end frameworks.
Design systems
A good base for your own design system, complete with a toolkit for setting up a documentation website.
