Calculate the Code Quality score of your CSS based on a range of different quality guards.

---

This package analyzes your CSS on a high level and comes up with a score, divided into three areas:

- **Maintainability**: how difficult is it for someone looking at the CSS from a high level to find the exact spot to fix a bug?
- **Complexity**: how difficult is it for someone to make a change and be confident that they can make that change without side effects?
- **Performance**: How likely is the CSS to have a negative impact on performance, based on high-level metrics? (Not including using hardware accelerated transforms and the like, because other tools are more suited for that.)

## Installation

```bash
npm install @projectwallace/css-code-quality
```

## Usage

```js
import { calculate } from "@projectwallace/css-code-quality";

let css = `my_css { /* ... */ }`;
let result = calculate(css);

/*
The result shape looks something like this:

{
"violations": [ ],
"passes": [ ],
"performance": {
"score": 90,
"violations": [ ],
"passes": [ ]
},
"maintainability": {
"score": 100,
"violations": [ ],
"passes": [ ]
},
"complexity": {
"score": 97,
"violations": [ ],
"passes": [ ]
}
}

Each `passes` or `violations` array contains an object that looks like this:

{
"id": "EmptyRules",
"score": 0,
"value": 0
},
{
"id": "AverageSelectorsPerRule",
"score": 0,
"value": 1.5,
"actuals": [
2,
1
]
}

etc. etc.

```
