handlebars-iron 0.7.1

Handlebars templating middleware for Iron.
Documentation

handlebars-iron

Handlebars middleware for the Iron web framework.

Build Status

The most recent version of handlebars-iron, like Iron and Handlebars-rust, now compiles on nightly, beta and 1.0 channel. Our travis task will track the compatibility on all three channels.

Usage

Add HandlebarsEngine to your Iron middleware chain as an "after" middleware.

  /// HandlebarsEngine will look up all files with "./examples/templates/**/*.hbs"
  chain.link_after(HandlebarsEngine::new("./examples/templates/", ".hbs"));

In your handler, set Template to response. As required by Handlebars-rust, your data should impl serialize::json::ToJson. If you are on nightly channel, it is highly recommended to use tojson_macros to generate default ToJson implementation without repeating yourself.

/// render data with "index" template
/// that is "./examples/templates/index.hbs"
fn hello_world(_: &mut Request) -> IronResult<Response> {
    let mut resp = Response::new();

    let data = ...
    resp.set_mut(Template::new("index", data)).set_mut(status:Ok);
    Ok(resp)
}

Since this is simple library, you may run this example with cargo run --example server first, and documentation then.

Since Rust and its ecosystem are still in early stage, this project might been broken for various reasons. I will try my best to keep this library compiles with latest Rust nightly before the 1.0 final release. If you find anything bad, pull requests and issue reporting are always welcomed.

Live reload

During development you may want to live-reload your templates without having to restart your web server. Here comes the live-reload feature.

    let template_engine_ref = Arc::new(HandlebarsEngine::new("./examples/templates/", ".hbs"));
    template_engine_ref.watch();

    chain.link_after(template_engine_ref);

Check examples/watch_server.rs for further information.
