Handlebars.js vs Liquid: What are the differences?

Introduction: In web development, Handlebars.js and Liquid are both popular templating languages that allow for dynamic content rendering. While they share some similarities, there are key differences between the two that make them unique and suitable for specific purposes. This article aims to highlight the major differences between Handlebars.js and Liquid.

1. Handlebars.js: Flexibility in templating Handlebars.js is a templating language that focuses on providing flexibility in creating templates. It allows for the execution of JavaScript code within templates, enabling developers to perform complex operations and calculations easily. Handlebars.js supports the use of helpers, which are custom functions that can be utilized within the templates to manipulate data or extend functionality.

2. Liquid: Easier and safer to use Liquid, on the other hand, prioritizes simplicity and safety. It restricts JavaScript execution within templates, eliminating potential security risks. Liquid templates also have a cleaner syntax, making it easier for non-technical users to create and manage templates. It provides a robust set of built-in filters and tags, enabling developers and content creators to manipulate data and control the output effectively.

3. Handlebars.js: Greater control over rendering logic Handlebars.js provides more control over the rendering logic. It supports conditional statements, loops, and partials, allowing developers to create dynamic templates that adapt to different scenarios. With Handlebars.js, developers have the flexibility to define custom logic and control the flow of the template rendering process.

4. Liquid: Enhanced for e-commerce and content management systems Liquid is widely used in e-commerce platforms and content management systems (CMS) such as Shopify. It has specific features tailored towards these domains, including support for product collections, variables related to orders and customers, and built-in functionality for managing e-commerce and CMS-related tasks. Liquid shines when it comes to efficiently handling the unique aspects of these systems.

5. Handlebars.js: Ideal for single-page applications When it comes to single-page applications (SPAs) or heavily client-side rendered applications, Handlebars.js excels. Its flexibility, ability to execute JavaScript code, and support for helpers make it suitable for handling complex rendering requirements in SPAs. Handlebars.js provides a seamless way to integrate with client-side frameworks and libraries, enabling efficient rendering on the front-end.

6. Liquid: Extensive usage across multiple platforms Liquid's popularity and extensive usage can be attributed to its versatility across multiple platforms. It is not limited to web development and has implementations in various programming languages. This allows it to be used in different contexts, including email templating, static site generators, and more, making Liquid a preferred choice for many developers working in diverse environments.

In summary, Handlebars.js offers greater flexibility and control over templating with its support for JavaScript execution and custom helpers, making it a suitable choice for SPAs. On the other hand, Liquid prioritizes simplicity and safety, excelling in e-commerce and CMS domains, while also being widely adopted in various platforms beyond web development.
