From Browser

import from FilterData object. And others are the same with From npm

const { filterData, SearchType } = FilterData;
.
.
.

From npm

1. search single key only.

   import { filterData, SearchType } from 'filter-data';
   
   // search firstName contains 'dan' and age < 20
   const searchConditions = [
     {
       key: 'firstName',
       value: 'dan',
       type: SearchType.LK,
     },
     {
       key: 'age',
       value: 20,
       type: SearchType.LT,
     },
   ];
   
   const result = filterData(data, searchConditions);
   // output:
   <!-- [
     { firstName: 'Daniel', age: 14 },
     { firstName: 'Dan', age: 18 },
   ] -->

2. search multiple keys.

   import { filterData, SearchType } from 'filter-data';
   
   // search firstName&lastName contains 'dan' and age < 20
   const searchConditions = [
     {
       key: ['firstName', 'lastName'],
       value: 'dan',
       type: SearchType.LK,
     },
     {
       key: 'age',
       value: 20,
       type: SearchType.LT,
     },
   ];
   
   const result = filterData(data, searchConditions);
   // output:
   <!-- [
     { firstName: 'Daniel', lastName: 'Johnson', age: 13 },
     { firstName: 'Jack', lastName: 'Danny', age: 19 },
   ] -->

3. caseSensitive.

   import { filterData, SearchType } from 'filter-data';
   
   // search firstName contains 'dan'
   const searchConditions = [
     {
       key: 'firstName',
       value: 'dan',
       type: SearchType.LK,
     },
   ];
   
   const result = filterData(data, searchConditions, { caseSensitive: true });
   // output:
   <!-- [
     { firstName: 'Jordan', age: 17 },
   ] -->

4. offset & limit.

   import { filterData, SearchType } from 'filter-data';
   
   // search firstName contains 'dan'
   const searchConditions = [
     {
       key: 'firstName',
       value: 'dan',
       type: SearchType.LK,
     },
   ];
   
   const result = filterData(data, searchConditions, { caseSensitive: true, offset: 10, limit: 10 });
   // output:
   <!-- [
     { firstName: 'Jordan', age: 17 },
     .
     .
     .
     max 10 records
   ] -->

5. search nested object.

   import { filterData, SearchType } from 'filter-data';
   
   // search firstName in father's sub object equals to 'dan'
   const searchConditions = [
     {
       key: 'father.firstName', // or key: [['father', 'firstName']]
       value: 'dan',
       type: SearchType.EQ,
     },
   ];
   
   const result = filterData(data, searchConditions);
   // output:
   <!-- [
     { firstName: 'Jordan', age: 17, father: { firstName: 'dan', age: 50 } },
   ] -->
