Introduction to Liquid Programming

Liquid is a template language created by Shopify and written in Ruby. It is designed as a flexible and safe way to add dynamic content to web pages, allowing developers to load data without needing to execute arbitrary code on the server. Liquid's syntax divides code into objects, tags, and filters. Objects tell Liquid where to show content on a page. Tags create the logic and control flow for templates, supporting operations like loops and conditions. Filters modify the output of Liquid objects for formatting purposes. An example of Liquid in action is displaying a list of products on a Shopify store's homepage. The template might loop through a collection of products, displaying each one's name, price, and image, formatted according to the shop's design preferences. Powered by ChatGPT-4o
