Overview

This library is purpose of do array / object operation like merge, clone, loop and some other processes. We always confuse to choose the best practices, performance and maintaining the common source from different developers.

This is very simple library written in typescript to resolve those conflicts. Since, it is written in typescript & npm combo will gave you extra feature like we can use it in typescript, javascript, angular, react and vuejs applications.

Installing Packages

Install the package from npm library.


npm install @azdreamic/data-lib --save

Sample Snippet to Use

import { ArrayProcessor } from '@azdreamic/data-lib';

const arr = [{ key: 1, value: 1 }, { key: 2, value: 2 }, { key: 3, value: 3 }];

let result = ArrayProcessor<{key:number,value:number}>(arr).filterByKeyValue('key', 2);

result.get();

Array Processor

Array Processor is to process the array. We can perform the array operation with ease.

The below function are available to use.

Reference API Docs link

Function Name	Description
deleteItemByIndex	To delete array item based on specified index.
deleteItemByKeyValue	To delete array item based on key and value.
filterByKeyValue	To filter an array items baded on key and value.
filterHasKey	To filter array items if has specified property.
forEach	To loop the each array.
get	To get final output after chained completed.
getActualArray	Get actual array from the after processed data from the instance.
getFirstObject	Return the first item of an array.
getIndexByKeyValue	To get the index number based on key and value.
groupBy	To group the array based on reviver logic.
insertItem	Add / insert item into an array.
insertItems	Add / Insert multiple items into an array.
map	Map is to transform object or modify the objects.
mergeByKeyValue	Merge object based on key & value.
operateByKey	This function used to perform the match calculation over the fields in array applicable for numbers
process	Process is similar to for each but here you can get along with instance
sortByKey	This function is to sort the array based on key
transformModelByKeys	This function is used to transform one object model to another by passing field mapping

Implementation Steps

Step 1

import the library


import { ArrayProcessor } from '@azdreamic/data-lib';

Step 2

Create the processor object based by passing array object to the array processor function.

let result = ArrayProcessor<{key:number,value:number}>(arr).filterByKeyValue('key', 2);

Step 3 Access the all methods continuos by using dot operator

result.filterByKeyValue('key','value').sortByKey('key');

Step 4

Get the final result by using get function

result.get();

Example

import { ArrayProcessor } from '@azdreamic/data-lib';

const arr = [{ key: 1, value: 1 }, { key: 2, value: 2 }, { key: 3, value: 3 }];

let result = ArrayProcessor<{key:number,value:number}>(arr).filterByKeyValue('key', 2);

result.get();
