Include Handlebars Templates for Rocket Framework

Build Status

This is a crate which provides macros handlebars_resources_initialize! and handlebars_response! to statically include HBS (Handlebars) files from your Rust project and make them be the HTTP response sources quickly.

Example

#![feature(proc_macro_hygiene, decl_macro)]

#[macro_use] extern crate lazy_static;
#[macro_use] extern crate lazy_static_include;

#[macro_use] extern crate handlebars;

#[macro_use] extern crate rocket_include_handlebars;

#[macro_use] extern crate rocket;

use std::collections::HashMap;

use rocket_include_handlebars::{EtagIfNoneMatch, HandlebarsResponse};

handlebars_resources_initialize!(
    "index", "examples/views/index.hbs",
    "index2", "examples/views/index2.hbs"
);

#[get("/")]
fn index() -> HandlebarsResponse {
    let mut map = HashMap::new();

    map.insert("title", "Title");
    map.insert("body", "Hello, world!");

    handlebars_response!("index", &map)
}

#[get("/2")]
fn index_2() -> HandlebarsResponse {
    let mut map = HashMap::new();

    map.insert("title", "Title");
    map.insert("body", "Hello, world!");

    handlebars_response!("index2", &map)
}

#[get("/static")]
fn index_static() -> HandlebarsResponse {
    handlebars_response_static!(
        "index".to_string(),
        {
            let mut map = HashMap::new();

            map.insert("title", "Title");
            map.insert("body", "Hello, world!");

            handlebars_response!("index", &map)
        }
    )
}
  • handlebars_resources_initialize! is used for including HBS files into your executable binary file. You need to specify each file's ID and its path. For instance, the above example uses index to represent the file included-handlebars/index.hbs and index-2 to represent the file included-handlebars/index2.hbs. An ID cannot be repeating.
  • handlebars_response! is used for retrieving and rendering the file you input through the macro handlebars_resources_initialize! as a HandlebarsResponse instance with rendered HTML. When its respond_to method is called, three HTTP headers, Content-Type, Content-Length and Etag, will be automatically added, and the rendered HTML can optionally be minified.
  • handlebars_response_static! is used for in-memory staticizing a HandlebarsResponse instance by a given key.

In order to reduce the compilation time, files are compiled into your executable binary file together, only when you are using the release profile.
