Expand description

Extension trait that provides handlebar rendering capabilities to [trillium::Conn]s.

Required Methods§

Source

fn assign(self, key: impl Into<Cow<'static, str>>, data: impl Serialize) -> Self

Registers an “assigns” value on this Conn for use in a template. See example usage at Handlebars::new

Source

fn render_with(self, template: &str, data: &impl Serialize) -> Self

renders a registered template by name with the provided data as assigns. note that this does not use any data accumulated by HandlebarsConnExt::assign

use trillium_handlebars::{HandlebarsHandler, Handlebars, HandlebarsConnExt};

#[derive(serde::Serialize)]
struct User { name: &'static str };

let mut handlebars = Handlebars::new();
handlebars.register_template_string("greet-user", "Hello {{name}}")?;

let handler = (
    HandlebarsHandler::new(handlebars),
    |mut conn: trillium::Conn| async move {
        conn.render_with("greet-user", &User { name: "handlebars" })
    }
);

use trillium_testing::prelude::*;
assert_ok!(get("/").on(&handler), "Hello handlebars");
