circus-handlebars

Implements Handlebars precompilation that is aware of Circus component dependencies when resolving helpers and partials.

Usage

Helpers

Helpers are implemented as simple CommonJS modules and circus-handlebars will handle registration of the helper, utilizing the filename.

module.exports = function() {
  return 'Content';
};

Implements the most basic helper method.

Programatically Loading Modules

Libraries that do not use a particular helper or partial directly may register the object via the partial and helper loaders.

require('helper!./helpers/i18n');
require('partial!./footer');

Will register the i18n helper and footer partial for use in any dependent projects, without having to reference either directly in a template within the hosting component.

Configuration

Used as a preprocessor for the Circus.config method:

var Circus = require('circus'),
    CircusHandlebars = require('circus-handlebars');

var config = {};
config = CircusHandlebars.config(config);
config = Circus.config(config);

circus-handlebars defines optional config values on the handlebars config key. These are:

  • helpersDir: Path to lookup helpers on. All javascript files within this directory are candidates for being automatically linked to helper candidate methods defined within templates. Defaults to ./src/lib/helpers.
  • extension: Extension used to resolve partial names. Defaults to .hbs.
  • knownHelpers: an array of strings defining helpers that are registered via registerHelper manually by libraries that are loaded into the application.
