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.

Explore the live demonstration available on CodeSandbox:

To install the package:

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

For CommonJS modules:

const Search = require('@smakss/search');

For ECMAScript modules:

import Search from '@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.

Lets suppose we have the following type:

type Person = { name: string; lastName: string };

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

const obj: Person = { name: 'John', lastName: 'Doe' };

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

const arr: Person[] = [
  { name: 'John', lastName: 'Doe' },
  { name: 'Joe', lastName: 'Doe' }
];

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

const nestedArr: (Person | Person[])[] = [
  { name: 'John', lastName: 'Doe' },
  { name: 'Joe', lastName: 'Doe' },
  [{ name: 'Jane', lastName: 'Doe' }]
];

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

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

const results = 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.

const results = 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.
