Evue is a high-performance gui application framework based on html/css, independent of platform and ui engine.

Users only need to understand simple html and css knowledge to quickly develop beautiful UI programs,

• Hardware independent and OS independent

The underlying UI engine of EVUE is based on Flutter and LVGL, and an EVUE application can run perfectly on multiple platforms such as windows/linux/macos/web/ios/android/RTOS, regardless of hardware and OS

• Develop once, run on multiple terminals

One-time development, multi-terminal operation means that users only need one-time development to realize multi-terminal operation of evue applets on different devices, and efficiently build multi-platform exquisite applications through a set of code libraries, which greatly improves user development efficiency and saves development cost

• Native performance, efficiency first
  • The underlying UI rendering engine of EVUE is based on Flutter and LVGL, with excellent performance
  • Flutter is Google’s open source toolkit for building user interface (UI). The underlying drawing engine is based on Skia, and its performance is comparable to that of native applications;
  • LVGL is a lightweight UI engine for IOT. The bottom layer is developed based on C language, with low memory usage and excellent performance. It is widely used in the IOT field
  • The EVUE framework itself adopts compile-time code generation technology and non-runtime dynamic rendering technology, which greatly reduces runtime performance consumption;
  • The EVUE framework natively supports MVVM, data-driven UI, and users do not need to care about manual UI operations, greatly improving development efficiency
• Component programming, free expansion

The EVUE framework itself is built on components, and everything is a component. Any evue file is a component. Based on the built-in native components, users can freely combine them into various custom advanced components, which can be reused in any project. Users are free design.

evue designer is a low-code designer developed based on evue. Users can simply drag and drop to realize automatic generation and preview of evue code, which greatly improves user development efficiency.
