bookmark_borderInject Storage in Laravel

Posted on by Kenny

How do you inject Storage in Laravel? I’ve noticed in my Google searches that all the examples I come across on how to use the various components of Laravel only show how to use Facades. But what if you want to use constructor injection?

If you would like to know how to inject the Storage Facade in Laravel, or more accurately, the FileSystem component, read on…

If you’re programming tests, you’ll come across cases where in order to test, you must inject. You don’t actually need to inject in the case of Storage, because the Facade has a “fake” method. However, what if you still want to so that you can remain consistent with the rest of your app?

It took me some serious searching to find the solution, but here it is:

<?php declare(strict_types = 1);

namespace App\Modules\Saver;

use Illuminate\Contracts\Filesystem\Factory as Filesystem;

class Saver
{
    /** @var Filesystem */
    private $storage;

    public function __construct(Filesystem $storage)
    {
        $this->storage = $storage;
    }

    /**
     * Save
     *
     * @param string $content
     */
    public function save(string $content): void
    {
        $this->storage->disk('local')->put('filename.txt', $content);
    }

Of course, you can override the disk name and filename dynamically if you need to. The test for this would look like:

    /** @test  */
    public function it_saves()
    {
        Storage::fake('local');

        /** @var Saver $saver */
        $saver = $this->app->make(Saver::class);
        $saver->save('some text');

        Storage::disk('local')->assertExists('filename.txt');
    }

You can still use the Storage facade in your test to make things simple.

I have been programming for over 20 years, most recently with Laravel. My goal is 100% test coverage wherever possible, and I’ve found that injection and mocking is necessary to do this in most cases. It’s interesting to see how differently you have to code in order to make testing possible. If you’re not testing your code, learn as much as you can about testing, then begin practicing. You’ll be surprised how much you’ll learn as you try to write tests and find you simply can’t because of the way your code is written.

Posted on by Kenny

In PHP 8, you can use named arguments, which allows you to provide the parameters of a function in any order:

PHP 7.x

// haystack must come first
$pos = strpos('Hello World', 'World');

PHP 8

// I can tell it what each param is, so the order is up to me
$pos = strpos(needle: 'World', haystack: 'Hello World');

Even if you choose not to reorder the params, it will make the code clearer and easier to read.

bookmark_borderA fast way to reformat code in PHPStorm

Posted on by Kenny

Today I found a way to do a regex find that makes reformatting code easy.

Let’s say we have some code like this:

<p>{{$variable}}</p>

and you want it formatted like this:

<p>{{ $variable }}</p>

This is what I prefer because it gives more breathing room and makes the code easier to read. But these can be scattered in many places in your code.

By doing a global find/replace using this regex, you can replace them all in one shot:

\{\{(?! )

It uses a negative lookahead, which means it will find all occurrences of {{ that are not followed by a space. You could find the closing portion by reversing it. Then use the global replace function and make your commit.

Get in, get it done, move on to the next task!
