trillium handler that rewrites html using lol-html and the
[lol_async] library.
this crate currently requires configuring the runtime,
unfortunately. use one of the "async-std", "smol", or "tokio"
features. do not use the default feature, it may change at any time.
use trillium_html_rewriter::{
html::{element, html_content::ContentType, Settings},
HtmlRewriter,
};
let handler = (
|conn: trillium::Conn| async move {
conn.with_header("content-type", "text/html")
.with_status(200)
.with_body("<html><body><p>body</p></body></html>")
},
HtmlRewriter::new(|| Settings {
element_content_handlers: vec![element!("body", |el| {
el.prepend("<h1>title</h1>", ContentType::Html);
Ok(())
})],
..Settings::default()
}),
);
