Shortcodes #

Various template engines can be extended with shortcodes for easy reusable content. This is sugar around Template Language Custom Tags. Shortcodes are supported in JavaScript, Liquid, Nunjucks, Handlebars templates. Here are a few examples:

Language: Nunjucks Liquid Handlebars 11ty.js
Filename sample.njk
{% user firstName, lastName %}

The comma between arguments is required in Nunjucks templates.

Filename sample.liquid
{% user firstName, lastName %}

The comma between arguments is optional in Liquid templates.

Filename sample.liquid
{% user firstName lastName %}
Filename sample.hbs
<!-- Note the three opening and closing curly brackets (the triple-stash) -->
{{{ user firstName lastName }}}
Note that if you return HTML in your Handlebars shortcode, you need to use the Handlebars triple-stash syntax (three opening and three closing curly brackets, e.g. {{{ shortcodeName }}}) to avoid double-escaped HTML. If it’s double-escaped a paragraph tag may render as &lt;p&gt;
Filename sample.11ty.js
module.exports = function({ firstName, lastName }) {
  return `<h1>${this.user(firstName, lastName)}</h1>`;
};
Markdown files are pre-processed as Liquid templates by default. This means that shortcodes available in Liquid templates are also available in Markdown files. Likewise, if you change the template engine for Markdown files, the shortcodes available for that templating language will also be available in Markdown files.
Filename .eleventy.js
module.exports = function(eleventyConfig) {
  // Liquid Shortcode
  eleventyConfig.addLiquidShortcode("user", function(firstName, lastName) { … });

  // Nunjucks Shortcode
  eleventyConfig.addNunjucksShortcode("user", function(firstName, lastName) { … });

  // Handlebars Shortcode
  eleventyConfig.addHandlebarsShortcode("user", function(firstName, lastName) { … });

  // JavaScript Template Function
  eleventyConfig.addJavaScriptFunction("user", function(firstName, lastName) { … });

  // Universal Shortcodes are added to:
  // * Liquid
  // * Nunjucks
  // * Handlebars
  // * JavaScript
  eleventyConfig.addShortcode("user", function(firstName, lastName) { … });
};

A shortcode returns content (a JavaScript string or template literal) that is injected into the template. You can use these however you’d like—you could even think of them as reusable components.

Paired Shortcodes #

The shortcodes we saw above were nice, I suppose. But really, they are not all that different from a filter. The real ultimate power of Shortcodes comes when they are paired. Paired Shortcodes have a start and end tag—and allow you to nest other template content inside!

Syntax Liquid, Nunjucks
{% user firstName, lastName %}
  Hello {{ someOtherVariable }}.

  Hello {% anotherShortcode %}.
{% enduser %}

The comma between arguments is required in Nunjucks but is optional in Liquid templates.

Syntax Handlebars
{{# user firstName lastName }}
  Hello {{ someOtherVariable }}.

  Hello {{ anotherShortcode }}.
{{/ user }}
Syntax JavaScript
module.exports = function(data) {
  let userContent = `Hello ${data.someOtherVariable}

Hello ${this.anotherShortCode()}`;

  return `<h1>${this.user(userContent, data.firstName, data.lastName)}</h1>`;
};

When adding paired shortcodes using the Configuration API, the first argument to your shortcode callback is the nested content.

Filename .eleventy.js
module.exports = function(eleventyConfig) {
  // Liquid Shortcode
  eleventyConfig.addPairedLiquidShortcode("user", function(content, firstName, lastName) { … });

  // Nunjucks Shortcode
  eleventyConfig.addPairedNunjucksShortcode("user", function(content, firstName, lastName) { … });

  // Handlebars Shortcode
  eleventyConfig.addPairedHandlebarsShortcode("user", function(content, firstName, lastName) { … });

  // JavaScript Template Function
  eleventyConfig.addJavaScriptFunction("user", function(content, firstName, lastName) { … });

  // Universal Shortcodes are added to:
  // * Liquid
  // * Nunjucks
  // * Handlebars
  // * JavaScript
  eleventyConfig.addPairedShortcode("user", function(content, firstName, lastName) { … });
};

Universal Shortcodes #

Universal shortcodes are added in a single place and subsequently available to multiple template engines, simultaneously. This is currently supported in JavaScript, Nunjucks, Liquid, and Handlebars template types.

Filename .eleventy.js
module.exports = function(eleventyConfig) {
  // Universal Shortcodes are added to:
  // * Liquid
  // * Nunjucks
  // * Handlebars
  // * JavaScript

  // Single Universal Shortcode
  eleventyConfig.addShortcode("myShortcode", function(firstName, lastName) { … });

  // Paired Universal Shortcode
  eleventyConfig.addPairedShortcode("user", function(content, firstName, lastName) { … });
};
