A simple, expressive and safe Shopify / Github Pages compatible template engine in pure JavaScript.
LiquidJS is a JavaScript implementation of the Liquid templating language, which was originally created by Shopify. It allows you to render dynamic content in your web applications by using a simple and readable syntax. LiquidJS is highly extensible and can be used both on the server-side with Node.js and in the browser.
Basic Template Rendering
This feature allows you to render basic templates with dynamic content. In this example, the template 'Hello, {{name}}!' is rendered with the variable 'name' set to 'World', resulting in 'Hello, World!'.
const { Liquid } = require('liquidjs');
const engine = new Liquid();
const template = 'Hello, {{name}}!';
engine.parseAndRender(template, { name: 'World' }).then(console.log);Loops
This feature allows you to iterate over arrays and render each item. In this example, the template iterates over the 'items' array and renders each item, resulting in 'apple banana cherry '.
const { Liquid } = require('liquidjs');
const engine = new Liquid();
const template = '{% for item in items %}{{ item }} {% endfor %}';
engine.parseAndRender(template, { items: ['apple', 'banana', 'cherry'] }).then(console.log);Conditionals
This feature allows you to use conditional statements in your templates. In this example, the template checks if the 'user' variable exists and renders 'Hello, Alice!' if it does, otherwise it renders 'Hello, Guest!'.
const { Liquid } = require('liquidjs');
const engine = new Liquid();
const template = '{% if user %}Hello, {{ user.name }}!{% else %}Hello, Guest!{% endif %}';
engine.parseAndRender(template, { user: { name: 'Alice' } }).then(console.log);Filters
This feature allows you to use filters to transform output. In this example, the 'upcase' filter is used to convert the string 'hello' to uppercase, resulting in 'HELLO'.
const { Liquid } = require('liquidjs');
const engine = new Liquid();
const template = '{{ "hello" | upcase }}';
engine.parseAndRender(template).then(console.log);Nunjucks is a powerful templating engine for JavaScript, inspired by Jinja2. It offers a similar feature set to LiquidJS, including template inheritance, macros, and filters. Nunjucks is known for its flexibility and ease of use, making it a strong alternative to LiquidJS.
Handlebars is a popular templating engine that provides a simple way to build semantic templates. It supports features like nested templates, partials, and helpers. Handlebars is known for its simplicity and performance, making it a good choice for projects that require straightforward templating.
EJS (Embedded JavaScript) is a templating engine that lets you generate HTML with plain JavaScript. It supports features like partials and includes, and is known for its simplicity and ease of integration with Express.js. EJS is a good option for developers who prefer a more JavaScript-centric approach to templating.
A simple, expressive and safe Shopify / Github Pages compatible template engine in pure JavaScript. The purpose of this repo is to provide a standard Liquid implementation for the JavaScript community so that Jekyll sites, Github Pages and Shopify templates can be ported to Node.js without pain.
Basically there're two types of Liquid syntax: tags enclosed by {% %} and outputs enclosed by {{ }}. A Liquid template looks like:
{% if username %}
{{ username | append: ", welcome to LiquidJS!" | capitalize }}
{% endif %}
A live demo is also available and here's a quick tutorial for Liquid syntax.
Install from npm in Node.js:
npm install liquidjs
Or use the UMD bundle from jsDelivr:
<script src="https://cdn.jsdelivr.net/npm/liquidjs/dist/liquid.browser.min.js"></script>
Or render directly from CLI using npx:
npx liquidjs --template 'Hello, {{ name }}!' --context '{"name": "Snake"}'
