Handlebars precompiler for sbt-web

sbt-hbs Build Status

sbt-web plugin for precompiling handlebars templates to javascript files, using the handlebarsjs compiler.


To use this plugin use the addSbtPlugin command within your project's plugins.sbt file:

resolvers += Resolver.sbtPluginRepo("releases")

addSbtPlugin("com.bicou.sbt" % "sbt-hbs" % "1.0.5")

Your project's build file also needs to enable sbt-web plugins. For example with build.sbt:

lazy val root = (project in file(".")).enablePlugins(SbtWeb)

Install handlebarsjs, either globally with npm:

npm install handlebars -g

Or locally in your project with a package.json file:

  "devDependencies": {
    "handlebars": "^3.0.0"

Supported settings

Option Description Default
amd When set, generates JavaScript with the AMD wrapper false
commonjs Exports CommonJS style, path to Handlebars module ""
handlebarPath Path to handlebar.js (only valid for amd-style) ""
known Known helpers []
knownOnly Known helpers only false
namespace Template namespace ""
root Template root (base value that will be stripped from template names) ""

The following sbt code illustrates how to generate templates with AMD wrapper

HbsKeys.amd := true


Once configured, any *.hbs or *.handlebars files placed in src/main/assets will be compiled to JavaScript code in target/web/public, the handlebars name is build from file path, relative to root option.

For example the name of the template located in app/assets/javascripts/templates/index.hbs will be javascripts/templates/index, unless you set HbsKeys.root := "javascripts/templates/" then it will be index (it's the handlebars id, not the javascript path).

If a file name begins with an underscore, it will be handled as a partial.

Don't forget to include the handlebars runtime via "org.webjars" % "handlebars" % "3.0.0-1" or by copying/linking in your public javascripts (node_modules/handlebars/dist/handlebars.runtime.js with npm).
