Elmio

A lightweight, proof-of-concept web framework loosely inspired by The Elm Architecture. It's built using the Rust programming language and compiles to WebAssembly.

What is Elmio?

A simple web framework that helps you build websites with Rust.

Elmio is like building with LEGO® blocks. You have different pieces that fit together to make a website:

• A place to store information (like a toy box)
• A way to handle actions (like pressing buttons)
• A way to show things on screen (like arranging LEGO® pieces)
• A way to make changes (like following LEGO® instructions)

Getting Started

1. Install Prerequisites:

cargo install elmio-cli wasm-pack

2. Create your first project:

elmio new my-website
cd my-website

3. Start your website:

elmio serve

How Elmio Works

Every Elmio website has four main parts:

1. State - Information your website remembers

   struct Model {
       count: isize,  // Remembers a number
   }
   

2. Messages - Things that can happen

   enum Msg {
       Increment,  // Add one
       Decrement,  // Subtract one
   }
   

3. View - What people see

   fn view(model: &Model) -> Markup {
       html! {
           button { "−" }
           span { (model.count) }
           button { "+" }
       }
   }
   

4. Update - How things change

   fn update(msg: &Msg, model: &mut Model) {
       match msg {
           Msg::Increment => model.count += 1,
           Msg::Decrement => model.count -= 1,
       }
   }
