metalsmith-register-helpers

A Metalsmith plugin for registering Handlebars helpers.

CLI Usage

Install via npm and then add the metalsmith-register-helpers key to your metalsmith.json plugins, like so:

{
  "plugins": {
    "metalsmith-register-helpers": {
      "directory": "path/to/helpers"
    }
  }
}

This will register all helpers in the specified directory, and use the first part of the filename as the helper name. As a simple (and admittedly contrived) example, you could add a helper that wraps everything in <strong> tags, stored in the file strong.js:

module.exports = function (content) {
  return '<strong>' + content + '</strong>'
}

And then access it in your templates:

<pre><code>{{ strong myJSONMetadata }}</code></pre>

Adding Handlebars Helpers

There are lots of helpers you could try this with in the Handlebars Helpers library. For example, add the capitalizeFirst helper into _helpers/capitalizeFirst.js:

/**
 * capitalizeFirst.js
 * http://git.io/vUJU2
 */
 
module.exports = function (str) {
  if (str && typeof str === "string") {
    return str.charAt(0).toUpperCase() + str.slice(1)
  }
}

Now, you can access it in your templates:

<h1>{{ capitalizeFirst "the lost typo devision." }}</h1>

You may also include multiple helpers in a single file:

module.exports = {
  capitalizeFirst: function (str) {
    if (str && typeof str === "string") {
      return str.charAt(0).toUpperCase() + str.slice(1)
    }
  },
  json: function (context) {
    return JSON.parse(context);
  },
  someOtherHelper: function () {
    // Etc.
  }
}

Adding devDependencies as helpers

If you’d prefer, this is another way to include helpers installed as dependencies in your package.json file into your Metalsmith project. For example, you can install the Moment Handlebars helper:

npm install --save helper-moment

Then, add it as a helper in _helpers/moment.js:

var helperMoment = require('helper-moment');
 
module.exports = function (str, pattern){
  return helperMoment(str, pattern)
}

You can now access it in your template:

<time date-time="{{ date }}">{{ moment date format="MMMM Do, YYYY"}}</time>
