A [shopify][shopify/liquid] compatible [Liquid][tutorial] template engine in pure JavaScript.
**The purpose of this repo** is to provide a standard Liquid implementation for the JavaScript community.
All features, filters and tags in [shopify/liquid](https://github.com/Shopify/liquid) are supposed to be built in LiquidJS,
though there are still some differences and limitations (see below).
> Version 9 has published, [see how to migrate to 9.0.0](https://github.com/harttle/liquidjs/wiki/Migrate-to-9)!
## Get Started
Install via npm:
```bash
npm install --save liquidjs
```
```javascript
var { Liquid } = require('liquidjs');
var engine = new Liquid();
engine
.parseAndRender('{{name | capitalize}}', {name: 'alice'})
.then(console.log); // outputs 'Alice'
```
Or include the UMD build, a live demo is available on jsfiddle: . You may need a [Promise polyfill][pp] for Node.js < 4 and ES5 browsers like [IE and Android UC][caniuse-promises].
```html
```
Also available from CLI:
```bash
echo '{{"hello" | capitalize}}' | npx liquidjs
```
For detailed documents, see:
* The [Wiki Page](https://github.com/harttle/liquidjs/wiki) contains tutorials and advanced topics.
* The [API Reference](https://harttle.github.io/liquidjs/classes/_liquid_.liquid.html) provides detailed descriptions for classes, methods and properties.
## Differences and Limitations
* Dynamic file locating (enabled by default), that means layout/partial names are treated as variables in liquidjs. See [#51](https://github.com/harttle/liquidjs/issues/51).
* Truthy and Falsy. All values except `undefined`, `null`, `false` are truthy, whereas in Ruby Liquid all except `nil` and `false` are truthy. See [#26](https://github.com/harttle/liquidjs/pull/26).
* Number. In JavaScript we cannot distinguish or convert between `float` and `integer`, see [#59](https://github.com/harttle/liquidjs/issues/59). And when applied `size` filter, numbers always return 0, which is 8 for integer in ruby, cause they do not have a `length` property.
* [.to_liquid()](https://github.com/Shopify/liquid/wiki/Introduction-to-Drops) is replaced by `.toLiquid()`
* [.to_s()](https://www.rubydoc.info/gems/liquid/Liquid/Drop) is replaced by JavaScript `.toString()`
Features that available on shopify website but not on shopify/liquid repo will not be implemented in this repo,
