It also includes some convenience functions to compare, sort, and filter an array of specificity values. + +Supports [Selectors Level 4](https://www.w3.org/TR/selectors-4/), including those special cases `:is()`, `:where()`, `:not()`, etc. + +Demo: [https://codepen.io/bramus/pen/WNXyoYm](https://codepen.io/bramus/pen/WNXyoYm) + +## Installation + +```bash +npm i @bramus/specificity +``` + +## Usage / Example + +At its core, `@bramus/specificity` exposes a `Specificity` class. Its static `calculate` method can be used to calculate the specificity of a given CSS [Selector List](https://www.w3.org/TR/selectors-4/#grouping) string. + +```js +import Specificity from '@bramus/specificity'; + +const specificities = Specificity.calculate('header:where(#top) nav li:nth-child(2n), #doormat'); +``` + +Because `calculate` accepts a [Selector List](https://www.w3.org/TR/selectors-4/#grouping) — which can contain more than 1 [Selector](https://www.w3.org/TR/selectors-4/#selector) — it will always return an array, with each entry being a `Specificity` instance — one per found selector. + +```js +const specificities = Specificity.calculate('header:where(#top) nav li:nth-child(2n), #doormat'); +specificities.map((s) => s.toString()); // ~> ["(0,1,3)","(1,0,0)"] +``` + +💡 If you know you’re passing only a single Selector into `calculate()`, you can use JavaScript’s built-in destructuring to keep your variable names clean. + +```js +const [s] = Specificity.calculate('header:where(#top) nav li:nth-child(2n)'); +s.toString(); // ~> "(0,1,3)" +``` + +💡 Under the hood, `@bramus/specificity` uses [CSSTree](https://github.com/csstree/csstree) to do the parsing of strings to Selectors. As a result, the `calculate` method also accepts a [CSSTree AST](https://github.com/csstree/csstree/blob/master/docs/ast.md) of the types `Selector` and `SelectorList`. + +If you have a pre-parsed CSSTree AST of the type `Selector` you can pass it into `Specificity.calculateForAST()`. It [performs slightly better](#benchmark) than `Specificity.calculate()` as it needs to check fewer things. It differs from `Specificity.calculate()` in that it does not return an array of `Specificity` instances but only a single value. + +## The Return Format + +A calculated specificity is represented as an instance of the `Specificity` class. The `Specificity` class includes methods to get the specificity value in a certain format, along with some convenience methods to compare it against other instances. + +```js +// 🚀 Thunderbirds are go! +import Specificity from '@bramus/specificity'; + +// ✨ Calculate specificity for each Selector in the given Selector List +const specificities = Specificity.calculate('header:where(#top) nav li:nth-child(2n), #doormat'); + +// 🚚 The values in the array are instances of the Specificity class +const s = specificities[0]; // Instance of Specificity + +// 👀 Read the specificity value using one of its accessors +s.value; // { a: 0, b: 1, c: 3 } +s.a; // 0 +s.b; // 1 +s.c; // 3 + +// 🛠 Convert the calculated value to various formats using one of the toXXX() instance methods +s.toString(); // "(0,1,3)" +s.toArray(); // [0, 1, 3] +s.toObject(); // { a: 0, b: 1, c: 3 } + +// 💡 Extract the matched selector string +s.selectorString(); // "header:where(#top) nav li:nth-child(2n)" + +// 🔀 Use one of its instance comparison methods to compare it to another Specificity instance +s.isEqualTo(specificities[1]); // false +s.isGreaterThan(specificities[1]); // false +s.isLessThan(specificities[1]); // true + +// 💻 Don’t worry about JSON.stringify() +JSON.stringify(s); +// { +// "selector": 'header:where(#top) nav li:nth-child(2n)', +// "asObject": { "a": 0, "b": 1, "c": 3 }, +// "asArray": [0, 1, 3], +// "asString": "(0,1,3)", +// } +``` + +## Utility Functions (Static Methods) + +This package also exposes some utility functions to work with specificities. These utility functions are all exposed as static methods on the `Specificity` class. + +- Comparing: + + - `Specificity.compare(s1, s2)`: Compares s1 to s2. Returns a value that can be: + - `> 0` = Sort s2 before s1 _(i.e. s1 is more specific than s2)_ + - `0` = Keep original order of s1 and s2 _(i.e. s1 and s2 are equally specific)_ + - `< 0` = Sort s1 before s2 _(i.e. s1 is less specific than s2)_ + - `Specificity.equals(s1, s2)`: Returns `true` if s1 and s2 have the same specificity. If not, `false` is returned. + - `Specificity.greaterThan(s1, s2)`: Returns `true` if s1 has a higher specificity than s2. If not, `false` is returned. + - `Specificity.lessThan(s1, s2)`: Returns `true` if s1 has a lower specificity than s2. If not, `false` is returned. + +- Sorting: + + - `Specificity.sortAsc(s1, s2, …, sN)`: Sorts the given specificities in ascending order _(low specificity to high specificity)_ + - `Specificity.sortDesc(s1, s2, …, sN)`: Sorts the given specificities in descending order _(high specificity to low specificity)_ + +- Filtering: + - `Specificity.min(s1, s2, …, sN)`: Filters out the value with the lowest specificity + - `Specificity.max(s1, s2, …, sN)`: Filters out the value with the highest specificity + +A specificity passed into any of these utility functions can be any of: + +- An instance of the included `Specificity` class +- A simple Object such as `{'a': 1, 'b': 0, 'c': 2}` + +## Utility Functions (Standalone) + +All static methods the `Specificity` class exposes are also exported as standalone functions using [Subpath Exports](https://nodejs.org/api/packages.html#subpath-exports). + +If you're only interested in including some of these functions into your project you can import them from their Subpath. As a result, your bundle size will be reduced greatly _(except for including the standalone `calculate`, as it returns an array of `Specificity` instances that relies on the whole lot)_ + +```js +import { calculate, calculateForAST } from '@bramus/specificity/core'; +import { compare, equals, greaterThan, lessThan } from '@bramus/specificity/compare'; +import { min, max } from '@bramus/specificity/filter'; +import { sortAsc, sortDesc } from '@bramus/specificity/sort'; +``` + +## Type Definitions + +Although `@bramus/specificity` is written in Vanilla JavaScript, it does include [Type Definitions](https://www.typescriptlang.org/docs/handbook/2/type-declarations.html) which are exposed via its `package.json`. + +## Binary/CLI + +`@bramus/specificity` exposes a binary named `specificity` to calculate the specificity of a given selector list on the CLI.
