shopify-liquid
Advanced tools
A feature-rich Liquid implementation for Node.js, with compliance with Jekyll and Github Pages. See:
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 partials
extname: '.liquid',
cache: false
});
engine.renderFile("hello.liquid", {name: 'alice'})
.then(function(html){
// html === 'Alice'
});
// equivalent to:
engine.renderFile("hello", {name: 'alice'})
.then(function(html){
// html === 'Alice'
});
cache default to false, extname default to .liquid, root default to "".
Undefined filters and variables will be rendered as empty string by default. Enable strict rendering to throw errors upon undefined variables/filters:
var opts = {
strict_variables: true,
strict_filters: true
};
engine.parseAndRender("{{ foo }}", {}, opts).catch(function(err){
// err.message === undefined variable: foo
});
engine.parseAndRender("{{ 'foo' | filter1 }}", {}, opts).catch(function(err){
// err.message === undefined filter: filter1
});
// Note: the below opts also work:
// engine.render(tpl, ctx, opts)
// engine.renderFile(path, ctx, opts)
// 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.
Download the dist files and import into your HTML.
And window.Liquid is what you want.
<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>
There's also a demo.
// 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'
}
});
