## 👉👉👉 Star LiquidJS  [![harttle/liquidjs](https://img.shields.io/github/stars/harttle/liquidjs?style=flat-square)][liquidjs]

Starring LiquidJS is the most important and easiest way to support us: boost its rank and expose it to more people, which in turn makes it better.

## Show Me Your Code

Getting started and building is described in [CONTRIBUTING.md](https://github.com/harttle/liquidjs/blob/master/CONTRIBUTING.md).

**Code Style**: LiquidJS applies [standard](https://github.com/standard/eslint-config-standard) and [@typescript-eslint/recommended](https://github.com/typescript-eslint/typescript-eslint/blob/master/packages/eslint-plugin/src/configs/recommended.json) rules.

**Testing**: Make sure test cases pass with your patch merged by running `npm test`

**Commit Message**: Please align to [the Angular Commit Message Guidelines](https://github.com/angular/angular.js/blob/master/DEVELOPERS.md#commits), especially note the [type identifier](https://github.com/angular/angular.js/blob/master/DEVELOPERS.md#type), on which semantic-release bot depends.

**Backward-Compatibility**: please be backward-compatible. LiquidJS is used by multiple layers of softwares, including underlying libraries, compilers, site generators and Web servers. It's not easy to do a major upgrade for most of them.
