Search

Searching through arrays, nested arrays, or objects for specific keywords can often be cumbersome, especially when dealing with deeply nested structures. This package simplifies that process by offering a lightweight, flexible search utility that delves into every key of an object or array elements to find matches. It utilizes ES6+ syntax, so if your codebase uses older standards, a transpiler might be required.

How it works?

To install the package:

npm i @smakss/search
# or
yarn add @smakss/search

For CommonJS modules:

constSearch=require('@smakss/search');

For ECMAScript modules:

importSearchfrom'@smakss/search';

Then, to utilize the search function within your application:

The Search function accepts an options object with the following properties:

• searchText (String): The string to search for.
• searchItems (Array|Object): The items or structure to search within.
• keys (Array): An array of keys to include or exclude from the search.
• include (Boolean): Determines whether to include (true) or exclude (false) the keys specified. Defaults to true.
• exact (Boolean): Determines whether to perform an exact match search. Defaults to false.

The search function can take a generic type to specify the type of the search items.

Examples of Usage

Lets suppose we have the following type:

typePerson={name: string;lastName: string};

Searching Within an Object

When the match is found in an object, the entire object is returned:

constobj: Person={name: 'John',lastName: 'Doe'};constresults=Search<Person>({searchText: 'john',searchItems: [obj]});// Results: [{ name: 'John', lastName: 'Doe' }]

Searching Within an Array

constarr: Person[]=[{name: 'John',lastName: 'Doe'},{name: 'Joe',lastName: 'Doe'}];constresults=Search<Person>({searchText: 'john',searchItems: arr});// Results: [{ name: 'John', lastName: 'Doe' }]

Searching Within a Nested Array

constnestedArr: (Person|Person[])[]=[{name: 'John',lastName: 'Doe'},{name: 'Joe',lastName: 'Doe'},[{name: 'Jane',lastName: 'Doe'}]];constresults=Search<Person|Person[]>({searchText: 'jane',searchItems: nestedArr});// Results: [{ name: 'Jane', lastName: 'Doe' }]

Including Specific Keys

constresults=Search<Person>({searchText: 'jane',searchItems: nestedArr,keys: ['name']});// Results: [{ name: 'Jane', lastName: 'Doe' }]

Excluding Specific Keys

constresults=Search<Person>({searchText: 'jane',searchItems: nestedArr,keys: ['lastName'],include: false});// Results: []

Note: The result is an empty array because 'lastName' is excluded from the search.

Performing an Exact Match Search

constresults=Search<Person>({searchText: 'jane',searchItems: nestedArr,exact: true});// Results: [{ name: 'Jane', lastName: 'Doe' }]

Note: Only the exact term 'Jane' is matched, not 'Janet' or other partial matches.
