Vigowebs / controller-action.php
Created January 2, 2023 14:51
This route will match a GET request to the /users URL and will call the index method of the UserController class. The index method retrieves a list of all users from the database using the User model and then returns a view file located at resources/views/users/index.blade.php, passing the $users variable to the view.
Route::get('/users', 'UserController@index');
class UserController extends Controller
{
public function index()
{
$users = User::all();
return view('users.index', compact('users'));
}

Vigowebs / Intl-segmentor.js
Created December 4, 2022 04:32
The Intl.Segmenter object enables locale-sensitive text segmentation, enabling you to get meaningful items (graphemes, words or sentences) from a string. Currently Intl.Segmenter is not supported in Firefox and Firefox for Android browsers.
const segmenterEn = new Intl.Segmenter('en', { granularity: 'word' });
const string1 = 'Split JavaScript Strings!';
[...segmenterEn.segment(string1)]
// [
// {segment: 'Split', index: 0, input: 'Split JavaScript Strings!', isWordLike: true}
// {segment: ' ', index: 5, input: 'Split JavaScript Strings!', isWordLike: false}
// {segment: 'JavaScript', index: 6, input: 'Split JavaScript Strings!', isWordLike: true}
// ...
// ]

Vigowebs / get-or-put-collection.php
Created October 12, 2022 06:40
getOrPut() can be used to fetch an item if it already exists, or insert it and fetch it if it doesn't. This can be really useful when building up a Collection with data from multiple sources and don't want duplicate items in our data.
// ❌
if (! $collection->has($key)) {
$collection->put($key, $this->builtItem($data));
}
return $collection->get($key);
// ✔️
return $collection->getOrPut($key, fn () => $this->buildItem($data));
