For more Info and examples

• All

  • Input[]: Array (Size: Unlimited).
  • Output: Array (Size: Unlimited).
  • Description: It takes an array of inputs and returns them again. It is used to run a list of nested Rules.

• Filter

  • Input[]: Array (Size: 2) {elements: any[], rule: IJsonLangParams}.
  • Output: Any[].
  • Description: It accepts array of elements with any type to filter them using nested/inner rules, the filter rule will pass each elements as a Data with scope Internal, to access it by the inner rules, you will need to use Data Rule with scope local, check this example.

• Map

  • Input[]: Array (Size: 2) {elements: any[], rule: IJsonLangParams}.
  • Output: Any[].
  • Description: It accepts array of elements with any type to map them using nested/inner rules, the filter rule will pass each elements as a Data with scope Internal, to access it by the inner rules, you will need to use Data Rule with scope local.

• Foreach

  • Input[]: Array (Size: 2) {elements: any[], rule: IJsonLangParams}.
  • Output: true.
  • Description: It accepts array of elements with any type to iterate over them using nested/inner rules, the filter rule will pass each elements as a Data with scope Internal, to access it by the inner rules, you will need to use Data Rule with scope local.

• Flatten

  • Input[]: Array (Size: 2) {elements: any[], level?: number}.
  • Output: true.
  • Description: It accepts array of elements with any type to flatten this array with any level.

💻Examples

import { JsonLang } from '@jsonlang/core';
import { LogicRules } from '@jsonlang/logic';
import { ArrayRules } from '@jsonlang/array';
import { ObjectRules } from '@jsonlang/object';

const jsonLang = new JsonLang();

jsonLang.import(LogicRules, ArrayRules, ObjectRules);

const result = jsonLang.execute({ $R: 'All', $I: [
  { 
    $R: 'Filter',
    $I: [[1, 3, 5], { $R: '>', $I: [{ $R: 'Data', $I: ['Internal'] }, 2] }]
  },
  { 
    $R: 'Filter',
    $I: [
      { $R: 'Get', $I: ['data.test', null, { $R: 'Data', $I: ['External'] }] },
      { $R: '<', $I: [{ $R: 'Data', $I: ['Internal'] }, 500] }
    ]
  }
] }, { data: { id: 'test', test: [100, 300, 700] } }, { sync: true });

console.log(result);

// [ [ 3, 5 ], [ 100, 300 ] ]

🔌 Compatibility

This library uses Array.map and Array.reduce, so it's not exactly Internet Explorer 8 friendly.
