# Openrarity

openRerity core algorithm JS implementation

use sky personal js lib

## 安装 Install

```js

npm i openrarity

```

## 测试 Test

```js

npm test

// normal rank

// same rank

```

## 基线测试 Benchmark

```js

npm run benchmark

/* gen Collection items: 100,000   Rarity calc time: 651 ms -- Mac M2

  { v: 1.010524265698629, toeknId: 53076, rank: 1 },

  { v: 1.009992300140172, toeknId: 10548, rank: 2 },

  '.....',

  { v: 0.9894947869513546, toeknId: 44396, rank: 100000 }

*/

```

## 覆盖率 Coverage

```js

npm run cov

/*

----------------|---------|----------|---------|---------|-------------------

File            | % Stmts | % Branch | % Funcs | % Lines | Uncovered Line #s

----------------|---------|----------|---------|---------|-------------------

All files       |     100 |      100 |     100 |     100 |

----------------|---------|----------|---------|---------|-------------------

*/

```

## 测试用例 Test Case

```js

const tokenScore = require('openrarity')

let metaData2 = [

  {

    trait1: 'value1',

    trait2: 'value1',

    trait3: 'value1'

  },

  {

    trait1: 'value1',

    trait2: 'value1',

    trait3: 'value1'

  },

  {

    trait1: 'value2',

    trait2: 'value1',

    trait3: 'value3'

  },

  {

    trait1: 'value2',

    trait2: 'value2',

    trait3: 'value3'

  },

  {

    trait1: 'value3 ',

    trait2: 'value3',

    trait3: 'value3'

  }

]

let r = tokenScore(metaData2)

/*

=>

  [

    { v: 1.3926137488801251, toeknId: 4, rank: 1 },

    { v: 1.1338031424711967, toeknId: 3, rank: 2 },

    { v: 0.8749925360622679, toeknId: 0, rank: 3 },

    { v: 0.8749925360622679, toeknId: 1, rank: 3 },

    { v: 0.7235980365241422, toeknId: 2, rank: 4 }

  ]

*/

```

## 算法步骤 Algorithm Step

- Generate trait value map without undefined(blank) trait

- Generate undefined(blank) trait for every token

- Generate trait value stats include traitEntropy

- Generate token trait probability list
