You can override a .liquid file’s template engine. Read more at Changing a Template’s Rendering Engine.

Liquid Options #

Default Options #

Rather than constantly fixing outdated documentation, find getLiquidOptions in Liquid.js. These options are different than the default liquidjs options.

Optional: Use your own options New in v0.2.15 #

It’s recommended to use the Configuration API to set override the default options above.

module.exports = function(eleventyConfig) {
eleventyConfig.setLiquidOptions({
dynamicPartials: true,
strict_filters: true
});
};

Optional: Set your own Library instance New in v0.3.0 #

As an escape mechanism for advanced usage, pass in your own instance of the Liquid library using the Configuration API. See all liquidjs options.

Not compatible with setLiquidOptions above—this method will override any configuration set there.
module.exports = function(eleventyConfig) {
let liquidJs = require("liquidjs");
let options = {
extname: ".liquid",
dynamicPartials: true,
strict_filters: true,
root: ["_includes"]
};

eleventyConfig.setLibrary("liquid", liquidJs(options));
};

Supported Features #

FeatureSyntax
✅ Include{% include user %} looks for _includes/user.liquid. Does not process front matter in the include file.
✅ Includes (Relative Path) New in v0.9.0Relative paths use ./ (template’s directory) or ../ (template’s parent directory): {% include ./included %} looks for included.liquid in the template’s current directory. Does not process front matter.

If _includes/included.liquid also exists, Liquid will use this file instead.
✅ Include (Quoted)
Liquid includes that use quotation marks require dynamicPartials: true—Read more at Quoted Include Paths.
{% include 'user' %} looks for _includes/user.liquid. Does not process front matter in the include file.
✅ Include (Relative Path, Quoted) New in v0.9.0
Liquid includes that use quotation marks require dynamicPartials: true—Read more at Quoted Include Paths.
Relative paths use ./ (template’s directory) or ../ (template’s parent directory): {% include './dir/user' %} looks for ./dir/user.liquid from the template’s current directory. Does not process front matter in the include file.

If _includes/dir/user.liquid also exists, Liquid will use this file instead.
✅ Include (pass in Data){% include 'user' with 'Ava' %}. Does not process front matter in the include file.
✅ Include (pass in Data){% include 'user', user1: 'Ava', user2: 'Bill' %}. Does not process front matter in the include file.

Quoted Include Paths #

This is a common pitfall if you’re using Liquid templates.

If you’d like to use quoted include paths, you must enable dynamicPartials: true in your Liquid options. This default may change in a future major version. Read more about this limitation at Issue #72.

Default behavior, dynamicPartials: false #

{% include user %} looks for _includes/user.liquid

Quoted includes with dynamicPartials: true #

{% include 'user' %} looks for _includes/user.liquid

Filters #

Filters are used to transform or modify content. You can add Liquid specific filters, but you probably want to add a Universal filter instead.

Read more about LiquidJS Filter syntax

module.exports = function(eleventyConfig) {
// Liquid Filter
eleventyConfig.addLiquidFilter("myLiquidFilter", function(myVariable) {});

// Universal filters (Adds to Liquid, Nunjucks, and Handlebars)
eleventyConfig.addFilter("myFilter", function(myVariable) {});
};

Usage #

<h1>{{ myVariable | myFilter }}</h1>

Multiple Filter Arguments #

module.exports = function(eleventyConfig) {
// Liquid Filter
eleventyConfig.addLiquidFilter("concatThreeStrings", function(arg1, arg2, arg3) {
return arg1 + arg2 + arg3;
});
};
<h1>{{ "first" | concatThreeThings: "second", "third" }}</h1>

Shortcodes #

Shortcodes are basically reusable bits of content. You can add Liquid specific shortcodes, but you probably want to add a Universal shortcode instead.

Shortcode #

Filename .eleventy.js
module.exports = function(eleventyConfig) {
  // Liquid Shortcode
  // These can be async functions too
  eleventyConfig.addLiquidShortcode("user", function(name, twitterUsername) { … });

  // Universal Shortcodes (Adds to Liquid, Nunjucks, Handlebars)
  eleventyConfig.addShortcode("user", function(name, twitterUsername) {
    return `<div class="user">
<div class="user_name">${name}</div>
<div class="user_twitter">@${twitterUsername}</div>
</div>`;
  });
};

liquidjs is already Promise-based internally, so an async function for a shortcode function works out of the box here.

Usage #

{% user "Zach Leatherman", "zachleat" %}

<!-- The comma between arguments is optional in Liquid templates -->
{% user "Zach Leatherman" "zachleat" %}
Outputs
<div class="user">
<div class="user_name">Zach Leatherman</div>
<div class="user_twitter">@zachleat</div>
</div>

Paired Shortcode #

module.exports = function(eleventyConfig) {
  // Liquid Shortcode
  // These can be async functions too
  eleventyConfig.addPairedLiquidShortcode("user2", function(bioContent, name, twitterUsername) { … });
  
  // Universal Shortcodes (Adds to Liquid, Nunjucks, Handlebars)
  eleventyConfig.addPairedShortcode("user2", function(bioContent, name, twitterUsername) {
    return `<div class="user">
<div class="user_name">${name}</div>
<div class="user_twitter">@${twitterUsername}</div>
<div class="user_bio">${bioContent}</div>
</div>`;
  });
};

liquidjs is already Promise-based internally, so an async function for a shortcode function works out of the box here.

Usage #

Note that you can put any Liquid tags or content inside the {% user %} shortcode! Yes, even other shortcodes!

{% user2 "Zach Leatherman" "zachleat" %}
Zach likes to take long walks on Nebraska beaches.
{% enduser %}
Outputs
<div class="user">
<div class="user_name">Zach Leatherman</div>
<div class="user_twitter">@zachleat</div>
<div class="user_bio">Zach likes to take long walks on Nebraska beaches.</div>
</div>

Asynchronous Shortcodes #

Liquid is already promise-based internally so async functions with await work fine out of the box.

Filename .eleventy.js
module.exports = function(eleventyConfig) {
eleventyConfig.addLiquidShortcode("user", async function(name, twitterUsername) {
return await fetchAThing();
});

eleventyConfig.addPairedShortcode("user2", async function(content, name, twitterUsername) {
return await fetchAThing();
});
};

Usage #

(It’s the same.)

{% user "Zach Leatherman" "zachleat" %}

{% user2 "Zach Leatherman" "zachleat" %}
Zach likes to take long walks on Nebraska beaches.
{% enduser2 %}
