Co-nested-hbs NPM

co-nested-hbs

Generator-based Handlebars templates for nested layouts.

koa-hbs is really great, but doesn't support nested layouts. Adding nested layouts to koa-hbs would unfortunately be a complete rewrite.

co-nested-hbs supports (nested) layouts, helpers, and partials.

Installation

$ npm install co-nested-hbs

Example

views/overall_layout.hbs

<html>
  <head>
    <title>{{title}}</title>
  </head>
  <body>
    {{{body}}}
  </body>
</html>

views/simple_theme.hbs

<header>
  Simple Theme!
</header>

<div class="simple_theme">
  {{{body}}}
</div>

<footer>
  Footer!
</footer>

views/home.hbs

<p>Welcome {{name}}!<p>

var r = require('rethinkdb');
var view = require('co-nested-hbs');

var html = await view.render('home', 'simple_theme', 'overall_layout', { title: 'Hello World!' });

html output would be:

<html>
  <head>
    <title>Hello World!</title>
  </head>
  <body>
    <header>
      Simple Theme!
    </header>

    <div class="simple_theme">
      <p>Welcome Bob!<p>
    </div>

    <footer>
      Footer!
    </footer>
  </body>
</html>

Usage

Partials are automatically registered if their filename matches _*.hbs, directory is ignored.

function *() {
  var view = require('co-nested-hbs')('view_path/goes/here', {
    layout: 'layout_file', // specify implied layout (or layouts) to be added to each render() call.
    partialsPath: 'path_to_partials',
    cache: true
  });

  // single template rendering
  var html = yield view.render('template', {local: 'variable'});

  // register helper
  view.registerHelper('link-to', function(url, text) {
    return "<a href='" + this.url + "'>" + this.text + "</a>";
  });

  // render the following templates in a chain, building the 'nest'
  var html = yield view.render('first_render', 'second_render', 'third_render');

  // locals can be applied to all templates when they are rendered
  var html = yield view.render('first_render', 'second_render', 'third_render', {title: 'Hello World!'}, {global_local: 'applied to all templates'});
}
