Building a Rust app with Perseus

Rust, renowned for its memory safety and high performance, is increasingly being utilized beyond system programming to include web application development, thanks to frameworks like Rocket, Axum, and Actix. The language is also gaining traction in building reactive frontends through the combination of Rust and WebAssembly. Perseus, a new Rust framework, offers a robust solution for frontend development by providing built-in support for reactivity and server-side rendering, leveraging the Sycamore library to build interactive user interfaces. This article walks through the process of creating a to-do application using Perseus, detailing the setup of the environment, structuring the app, defining state, and integrating interactive features like adding and removing tasks. It explains Perseus's integration with the Axum web framework and the importance of creating custom error views for production deployment. Perseus stands out by not using a virtual DOM, potentially enhancing performance and offering Rust developers a solid alternative for developing secure and efficient applications.
