A feature-rich Liquid template engine for Node.js and browsers, with compliance with the Ruby version. New to Liquid? Here's a live demo: http://harttle.com/shopify-liquid/
The Liquid template engine is implemented in Ruby originally, which is used by Jekyll and Github Pages.
Features:
Installation:
npm install --save shopify-liquid
Parse and Render:
var Liquid = require('shopify-liquid');
var engine = Liquid();
engine.parseAndRender('{{name | capitalize}}', {name: 'alice'})
.then(function(html){
// html === 'Alice'
});
Caching templates:
var tpl = engine.parse('{{name | capitalize}}');
engine.render(tpl, {name: 'alice'})
.then(function(html){
// html === 'Alice'
});
var engine = Liquid({
root: path.resolve(__dirname, 'views/'), // for layouts and includes
extname: '.liquid',
cache: false,
strict_filters: false, // default: false
strict_variables: false // default: false
});
engine.renderFile("hello.liquid", {name: 'alice'})
.then(function(html){
// html === 'Alice'
});
// equivalent to:
engine.renderFile("hello", {name: 'alice'})
.then(function(html){
// html === 'Alice'
});
root is a directory or an array of directories to resolve layouts and includes, as well as the filename passed in when calling .renderFile().
If an array, the files are looked up in the order they occur in the array.
Defaults to process.cwd()
extname is used to lookup the template file when filepath doesn't include an extension name. Defaults to .liquid
cache indicates whether or not to cache resolved templates. Defaults to false.
strict_filters is used to enable strict filter existence. If set to false, undefined filters will be rendered as empty string. Otherwise, undefined filters will cause an exception. Defaults to false.
strict_variables is used to enable strict variable derivation.
If set to false, undefined variables will be rendered as empty string.
Otherwise, undefined variables will cause an exception. Defaults to false.
// register liquid engine
app.engine('liquid', engine.express({
strict_variables: true, // Default: fasle
strict_filters: true // Default: false
}));
app.set('views', './views'); // specify the views directory
app.set('view engine', 'liquid'); // set to default
There's an Express demo here.
When using with Express.js, partials(includes and layouts) will be looked up in
both Liquid root and Express views directories.
Download the dist files and import into your HTML.
And window.Liquid is what you want. There's also a demo.
<html lang="en">
<head>
<script src="dist/liquid.min.js"></script>
</head>
<body>
<script>
var engine = window.Liquid();
var src = '{{ name | capitalize}}';
var ctx = {
name: 'welcome to Shopify Liquid'
};
engine.parseAndRender(src, ctx)
.then(function(html) {
// html === Welcome to Shopify Liquid
});
</script>
</body>
</html>
Note: In IE and Android UC browser, you need a Promise implementation registered to any-promise.
// file: color.liquid
color: '{{ color }}' shape: '{{ shape }}'
// file: theme.liquid
{% assign shape = 'circle' %}
{% include 'color' %}
{% include 'color' with 'red' %}
{% include 'color', color: 'yellow', shape: 'square' %}
The output will be:
color: '' shape: 'circle'
color: 'red' shape: 'circle'
color: 'yellow' shape: 'square'
// file: default-layout.liquid
Header
{% block content %}My default content{% endblock %}
Footer
// file: page.liquid
{% layout "default-layout" %}
{% block content %}My page content{% endblock %}
The output of page.liquid:
Header
My page content
Footer
// Usage: {{ name | uppper }}
engine.registerFilter('upper', function(v){
return v.toUpperCase();
});
See existing filter implementations: https://github.com/harttle/shopify-liquid/blob/master/filters.js
// Usage: {% upper name%}
engine.registerTag('upper', {
parse: function(tagToken, remainTokens) {
this.str = tagToken.args; // name
},
render: function(scope, hash) {
var str = Liquid.evalValue(this.str, scope); // 'alice'
return Promise.resolve(str.toUpperCase()); // 'Alice'
}
});
