cd ratzilla

Moves into the project folder you just downloaded.

2. Official Install Script

Easy Recommended

Prerequisites

Rust (rustup) Rust is required to use cargo.

cargo install cargo-generate

Builds and installs the package published on crates.io — no need to clone the repo yourself.

✅ After installing, open a new terminal and run the program's version command (e.g. --version) to confirm it worked.

Pulled directly from this repo's README.

3. Rust

Medium

Prerequisites

Git Needed to download the project code from GitHub.
Rust (rustup) Installing via rustup also installs cargo.

cargo install cargo-generate

Builds and installs the package published on crates.io — no need to clone the repo yourself.

cargo generate ratatui/ratzilla

Type this command into your terminal and run it.

cargo add ratzilla

Type this command into your terminal and run it.

✅ If cargo build finishes without errors, it worked. The executable is created under target/.

# Ratzilla

Build terminal-themed web applications with Rust and WebAssembly. Powered by [Ratatui].

## Quickstart

### Templates

Install [`cargo-generate`](https://github.com/cargo-generate/cargo-generate):

```shell
cargo install cargo-generate
```

Generate a new project:

```shell
cargo generate ratatui/ratzilla
```

And then [serve the application on your browser](#serve) ➡️

See [templates](./templates) for more information.

### Manual Setup

Add **Ratzilla** as a dependency in your `Cargo.toml`:

```sh
cargo add ratzilla
```

Here is a minimal example:

```rust no_run
use std::{cell::RefCell, io, rc::Rc};

use ratzilla::ratatui::{
    layout::Alignment,
    style::Color,
    widgets::{Block, Paragraph},
    Terminal,
};

use ratzilla::{event::KeyCode, DomBackend, WebRenderer};

fn main() -> io::Result<()> {
    let counter = Rc::new(RefCell::new(0));
    let backend = DomBackend::new()?;
    let mut terminal = Terminal::new(backend)?;

terminal.on_key_event({
        let counter_cloned = counter.clone();
        move |key_event| {
            if key_event.code == KeyCode::Char(' ') {
                let mut counter = counter_cloned.borrow_mut();
                *counter += 1;
            }
        }
    })?;

terminal.draw_web(move |f| {
        let counter = counter.borrow();
        f.render_widget(
            Paragraph::new(format!("Count: {counter}"))
                .alignment(Alignment::Center)
                .block(
                    Block::bordered()
                        .title("Ratzilla")
                        .title_alignment(Alignment::Center)
                        .border_style(Color::Yellow),
                ),
            f.area(),
        );
    });

Ok(())
}
```

Add your `index.html`. During build, `trunk` will automatically inject and initialize your Rust code (compiled to
WebAssembly) as a JavaScript module.

<details>
  <summary>index.html</summary>
  
```html
<!doctype html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta
      name="viewport"
      content="width=device-width, initial-scale=1.0, user-scalable=no"
    />
    <link

    <title>Ratzilla</title>
    <style>
      body {
        margin: 0;
        width: 100%;
        height: 100vh;
        display: flex;
        flex-direction: column;
        justify-content: center;
        align-items: center;
        align-content: center;
        background-color: #121212;
      }
      pre {
        font-family: "Fira Code", monospace;
        font-size: 16px;
        margin: 0px;
      }
    </style>
  </head>
  <body>
    
    <script type="module">
      window.addEventListener("TrunkApplicationStarted", (_) => {
        // #[wasm_bindgen] functions are now bound to window.wasmBindings.*
        console.log("application initialized");
      });
    </script>
  </body>
</html>
```

</details>

And then [serve the application on your browser](#serve) ➡️

## Serve

Install [trunk] to build and serve the web application.

```sh
cargo install --locked trunk
```

Add compilation target `wasm32-unknown-unknown`:

```sh
rustup target add wasm32-unknown-unknown
```

Then serve it on your browser:

```sh
trunk serve
```

Now go to [http://localhost:8080](http://localhost:8080) and enjoy TUIs in your browser!

## Deploy

To build the WASM bundle, you can run the following command:

```sh
trunk build --release
```

Then you can serve the server from the `dist` directory.

<details>
  <summary>Example Build Script</summary>

```bash
#!/bin/bash
set -euo pipefail
export HOME=/root

# Install Rustup
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y -t wasm32-unknown-unknown --profile minimal
source "$HOME/.cargo/env"

# Install trunk using binstall
curl -L --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/cargo-bins/cargo-binstall/main/install-from-binstall-release.sh | bash
cargo binstall --targets x86_64-unknown-linux-musl -y trunk

# Build project with trunk
trunk build --release
```

</details>
