# 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 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.
index.html
```html
Ratzilla
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;
}
window.addEventListener("TrunkApplicationStarted", (_) => {
// #[wasm_bindgen] functions are now bound to window.wasmBindings.*
console.log("application initialized");
});
```
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.
Example Build Script
```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
```
