livid

livid is a lightweight frontend Rust crate for creating web apps via webassembly. It's a thin wrapper around web-sys and also light on macros!

Requirements

The wasm32-unknown-unknown target: rustup target add wasm32-unknown-unknown

Usage

Install the trunk crate (to simplify building and bundling your web app): cargo install trunk
Create an index.html file in your root directory: html <html> <head> <meta charset="utf-8"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> </head> </html>
You can add links to CSS files/urls, and use Widget::setclassname() to benefit from CSS styling.
Create a project: toml [dependencies] livid = "0.1"

In your Rust source file:

```rust use livid::{Document, Event, Style, Widget, WidgetType, IsElementIterable};

fn div() -> Widget { Widget::new(WidgetType::Div) }

fn btn(i: i32) -> Widget { let btn = Widget::new(WidgetType::Button); let (label, col) = if i > 0 { ("Increment", "green") } else { ("Decrement", "red") }; btn.settextcontent(Some(label)); btn.setstyle(Style::Color, col); btn.addcallback(Event::Click, move || { let result = Widget::fromid("result").unwrap(); let mut old: i32 = result.textcontent().unwrap().parse().unwrap(); old += i; result.settextcontent(Some(&old.tostring())); }); btn }

fn main() { Document::get().set_title("Counter");

let btn_inc = btn(1);
let btn_dec = btn(-1);

let main_div = div();
main_div.append(&btn_inc);
main_div.append(&btn_dec);

let result = div();
result.set_id("result");
result.set_text_content(Some("0"));
result.set_style(Style::FontSize, "22px");

let btns = Document::get().get_elements_by_tag_name("BUTTON");
for btn in btns.iter() {
    // set their fontSize to 22 pixesl
    btn.set_style(Style::FontSize, "22px");
}

} ```

Build and serve using Trunk: trunk build or trunk serve

Example with CSS

```rust use livid::{Document, Widget, WidgetType::{self, *}};

fn w(typ: WidgetType) -> Widget { Widget::new(typ) }

fn main() { Document::get().settitle("Form"); Document::addcsslink("https://cdn.jsdelivr.net/npm/bulma@0.9.3/css/bulma.min.css"); Document::addcss_link("https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css");

let form = w(Form);
form.set_class_name("box");
form.append(&{
    let div = w(Div);
    div.set_class_name("field");
    div.append(&{
        let label = w(Label);
        label.set_class_name("label");
        label.set_inner_html(r#"<span class='fa fa-envelope'></span> Email"#);
        label
    });
    div.append(&{
        let div = w(Div);
        div.set_class_name("control");
        div.append(&{
            let inp = w(Input);
            inp.set_class_name("input");
            inp.set_attribute("type", "email").unwrap();
            inp.set_attribute("placeholder", "m@gmail.com").unwrap();
            inp
        });
        div
    });
    div
});

} ```
