zmilan/perseus

A high-level web development framework for Rust with full support for server-side rendering and static generation.

Perseus

Perseus is a blazingly fast frontend web development framework built in Rust with support for major rendering strategies, reactivity without a virtual DOM, and extreme customizability. It wraps the lower-level capabilities of Sycamore!

• 📕 Supports static generation (serving only static resources)
• 🗼 Supports server-side rendering (serving dynamic resources)
• 🔧 Supports revalidation after time and/or with custom logic (updating rendered pages)
• 🛠️ Supports incremental regeneration (build on demand)
• 🏭 Open build matrix (use any rendering strategy with anything else)
• 🖥️ CLI harness that lets you build apps with ease and confidence
• 🌐 Full i18n support out-of-the-box with Fluent

Usage

Here's a taste of Perseus (see the tiny example for more):

use perseus::{define_app, ErrorPages, Template};
use sycamore::template;
define_app! {
    templates: [
        Template::<G>::new("index").template(|_| {
            template! {
                p { "Hello World!" }
            }
        })
    ],
    error_pages: ErrorPages::new(|url, status, err, _| {
        template! {
            p { (format!("An error with HTTP code {} occurred at '{}': '{}'.", status, url, err)) }
        }
    })
}

Aim

Support every major rendering strategy and provide developers the ability to efficiently create super-fast apps with Rust and a fantastic developer experience!

Motivation

There is a sore lack of Rust frameworks for frontend development that support more than just SPAs and client-side rendering, and so Perseus was born. We need something like NextJS for Wasm.

Roadmap

Pre-stable

These tasks still need to be done before Perseus can be pushed to v1.0.0.

• Create a custom CLI as a harness for apps without ridiculous amounts of configuration needed

• Support i18n out of the box
• Implement custom router
• Allow direct modification of the document head
• Improve SEO and initial load performance
• Support custom template hierarchies
• Pre-built integrations
  • Actix Web
  • Warp
  • AWS Lambda

Beyond

These tasks will be done after Perseus is stable.

• Integrations for other platforms
