Liquid Introduction
Introduction to Shopify Liquid
Liquid is Shopify's templating language for dynamic e-commerce theme rendering.
What is Liquid?
Liquid is a powerful templating language developed by Shopify to facilitate the creation of dynamic e-commerce websites. It acts as a bridge between the HTML of your Shopify themes and the data stored in Shopify's backend, allowing you to create personalized and data-driven content for your online store.
Liquid files have the extension .liquid and are used in Shopify themes to render static and dynamic content. By utilizing Liquid's tags, filters, and objects, developers can create highly customized and functional storefronts.
Basic Syntax of Liquid
Liquid syntax consists of three main components: objects, tags, and filters.
- Objects: These are used to output dynamic content. Objects are enclosed in double curly braces, e.g.,
{{ product.title }}. - Tags: Tags control the logic and flow of templates. They are enclosed in curly braces and percentage signs, e.g.,
{% if user %}Welcome, {{ user.name }}!{% endif %}. - Filters: Filters modify the output of objects and are placed within an object tag, e.g.,
{{ product.price | money }}.
Using Liquid Objects
Liquid objects are placeholders for the data that comes from Shopify's store. They allow you to dynamically display content based on the store's products, collections, and other attributes.
For example, to display a product's title, you would use:
Implementing Liquid Tags
Liquid tags are used to implement logic within templates. They help in controlling the template's flow based on conditions or loops.
Here is an example of using an if tag to check if a user is logged in:
Modifying Output with Liquid Filters
Filters in Liquid are used to alter the output of objects. They can format text, convert data types, and apply various transformations.
For instance, to format a product's price to display as currency, you can use the | money filter:
