-This is a liquid implementation for both Node.js and browsers. Website: <http://harttle.github.io/liquidjs/>, Live Demo: <https://jsfiddle.net/6u40xbzs/> 
+A simple, expressive, safe and [Shopify][shopify/liquid] 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](https://jekyllrb.com), [Github Pages](https://pages.github.com/) and [Shopify templates](https://themes.shopify.com/) can be ported to Node.js without pain.

-**Features**
+* [Documentation][doc]
+* Please star [LiquidJS on GitHub][github]!
+* Support [LiquidJS on Open Collective][oc] or [Patreon][patreon]

-* Fully compatible to [shopify][shopify/liquid], with all [tags][tags] and [filters][filters] implemented
-* Support layout(extend) and include syntax
-* In pure JavaScript with Promise-based API

-**Differences**
+## Installation

-Though being compatible with [Ruby Liquid](https://github.com/shopify/liquid) is one of our priorities, there're still certain differences. You may need some configuration to get it compatible in these senarios:
-
-* Dynamic file locating (enabled by default), which means layout/partial name can be an variable 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 Rendering. Since JavaScript do not distinguish `float` and `integer`, we cannot either convert between them nor render regarding to their type. See [#59](https://github.com/harttle/liquidjs/issues/59).
-* [.to_liquid()](https://github.com/Shopify/liquid/wiki/Introduction-to-Drops) has a `.toLiquid()` alias and and the JavaScript `.toString()` is aliased to `.to_s()`.
-* [.to_s()](https://www.rubydoc.info/gems/liquid/Liquid/Drop) uses `JSON.prototype.stringify` as default, rather than Ruby's inspect.

-Install as Node.js dependency:
+Install from npm in Node.js:

 ```bash
-# You'll need a promise-polyfill for Node.js < 4
 npm install --save liquidjs
 ```

-Parse and Render:
+Or use the UMD bundle from jsDelivr:

-```javascript
-var Liquid = require('liquidjs');
-var engine = new Liquid();
-
-engine
-    .parseAndRender('{{name | capitalize}}', {name: 'alice'})
-    .then(console.log);
-
-// outputs 'Alice'
+```html
+<script src="https://cdn.jsdelivr.net/npm/liquidjs/dist/liquid.browser.min.js"></script>
 ```

-Caching templates:
+More details, refer to [The Setup Guide][setup].

-```javascript
-var tpl = engine.parse('{{name | capitalize}}');
-engine
-    .render(tpl, {name: 'alice'})
-    .then(console.log);

-## Render from File
+## Backers

-```javascript
-var engine = new Liquid({
-    root: path.resolve(__dirname, 'views/'),  // dirs to lookup layouts/includes
-    extname: '.liquid'          // the extname used for layouts/includes, defaults ""
-});
-engine.renderFile("hello.liquid", {name: 'alice'})
-    .then(console.log)  // outputs "Alice"
+If you love LiquidJS or your company is using LiquidJS? Please consider [support us on Open Collective or Patreon][financial-support].

-// which is equivalent to: 
-engine
-    .renderFile("hello", {name: 'alice'})
-    .then(console.log)  // outputs "Alice"
-```

-## Include Partials
-
-```
-// 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'
-```
-
-## Layout Templates (Extends)
-
-```
-// 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
-```
-
-* It's possible to define multiple blocks.
-* block name is optional when there's only one block.
-
-## Options
-
-The full list of options for `Liquid()` is listed as following:
-
-* `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 `["."]`
-
-* `extname` is used to lookup the template file when filepath doesn't include an extension name. Eg: setting to `".html"` will allow including file by basename. Defaults to `""`.
-
-* `cache` indicates whether or not to cache resolved templates. Defaults to `false`.
-
-* `dynamicPartials`: if set, treat `<filepath>` parameter in `{%include filepath %}`, `{%layout filepath%}` as a variable, otherwise as a literal value. Defaults to `true`.
-
-* `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`.
-
-* `trim_tag_right` is used to strip blank characters (including ` `, `\t`, and `\r`) from the right of tags (`{% %}`) until `\n` (inclusive). Defaults to `false`.
-
-* `trim_tag_left` is similiar to `trim_tag_right`, whereas the `\n` is exclusive. Defaults to `false`. See [Whitespace Control][whitespace control] for details.
-
-* `trim_output_right` is used to strip blank characters (including ` `, `\t`, and `\r`) from the right of values (`{{ }}`) until `\n` (inclusive). Defaults to `false`.
-
-* `trim_output_left` is similiar to `trim_output_right`, whereas the `\n` is exclusive. Defaults to `false`. See [Whitespace Control][whitespace control] for details.
-
-* `tag_delimiter_left` and `tag_delimiter_right` are used to override the delimiter for liquid tags.
-
-* `output_delimiter_left` and `output_delimiter_right` are used to override the delimiter for liquid outputs.
-
-* `greedy` is used to specify whether `trim_left`/`trim_right` is greedy. When set to `true`, all consecutive blank characters including `\n` will be trimed regardless of line breaks. Defaults to `true`.
-
-## Register Filters
-
-```javascript
-// Usage: {{ name | uppper }}
-engine.registerFilter('upper', v => v.toUpperCase())
-```
-
-Filter arguments will be passed to the registered filter function, for example:
-
-```javascript
-// Usage: {{ 1 | add: 2, 3 }}
-engine.registerFilter('add', (initial, arg1, arg2) => initial + arg1 + arg2)
-```
-
-See existing filter implementations here: <https://github.com/harttle/liquidjs/tree/master/src/builtin/filters>
-
-## Register Tags
-
-```javascript
-// 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'
-    }
-});
-```
-
-* `parse`: Read tokens from `remainTokens` until your end token.
-* `render`: Combine scope data with your parsed tokens into HTML string.
-
-See existing tag implementations here: <https://github.com/harttle/liquidjs/tree/master/src/builtin/tags>
-
-## Plugin API
-
-A pack of tags or filters can be encapsulated into a **plugin**, which will be typically installed via npm.
-
-```javascript
-engine.plugin(require('./some-plugin'));
-
-// some-plugin.js
-module.exports = function (Liquid) {
-    // here `this` refers to the engine instance
-    // `Liquid` provides facilities to implement tags and filters
-    this.registerFilter('foo', x => x);
-}
-```

+# Security Policy
+
+## Supported Versions
+
+Only the latest major version is supported with security updates. It can be changed if many people are relying on a specific version for some reason. If this is the case, welcome to file an issue.
+
+## Reporting a Vulnerability
+
+Please contact yangjvn@126.com to report a vulnerability.
+
+- It will be fixed very soon (maybe within 1 week or couple of days) if that vulnerability obviously affects common use cases.
+- Otherwise, it'll be scheduled with a priority just like requested features (which is lower than bugs).
+- If it's declined, you'll receive an email (more oftenly there will be a discuss).
