Leptos

Leptos is a full-stack, isomorphic Rust web framework designed for building fast web applications. It leverages fine-grained reactivity to create declarative user interfaces, which allows for highly performant code with minimal overhead. Leptos can be used for client-side rendering, server-side rendering, or a combination of both, including support for HTTP streaming of data and HTML.

The framework supports writing isomorphic server functions that can be called from the client-side but run on the server, streamlining the development process by eliminating the need for separate REST APIs. Built on web standards, Leptos aims to integrate seamlessly with the Web platform, providing a router that leverages fundamental web concepts like links and forms.

Leptos offers a comprehensive toolkit for web development, including a reactive system, templating library, and a router that works on both the server and client sides. The reactive system allows for efficient updates to the DOM by changing only the necessary parts without the overhead of a virtual DOM.

For those new to the framework, Leptos provides a book, examples, and API documentation to help developers get started. It also supports the use of nightly Rust for advanced features and provides a build tool called cargo-leptos for seamless integration of client and server-side code.

Leptos distinguishes itself from other frameworks such as Yew, Dioxus, and Sycamore through its fine-grained reactivity, performance optimizations, and holistic approach to web performance. The framework is actively developed and has a growing community and ecosystem.

Leptos is suitable for building modern web applications and can even be adapted for native GUI development, offering a versatile solution for developers looking to leverage Rust's performance and safety in web development.
