Overview

A Laravel package that allows you to add 47 different styles of loading spinners to your Artisan commands.

Installation

Requirements

The package has been developed and tested to work with the following minimum requirements:

PHP 8
Laravel 8

Install the Package

You can install the package via Composer:

composer require ashallendesign/laravel-command-spinner

Usage

Adding Loading Spinners to Commands

Using a loading spinner can be useful for when executing long-running commands, such as fetching data from an API.

To add a loading spinner to your command, first start by adding HasSpinner trait to your command. After that, you can then use the withSpinner() method like shown in the example below:

use AshAllenDesign\CommandSpinner\Traits\HasSpinner;

class YourCommand extends Command
{
    use HasSpinner;

    public function handle(): int
    {
        $this->withSpinner(function () {
            // Run your code here.
        });
    }
}

Adding Text to the Spinner

When you're displaying a loading spinner in your console command, you may wish to also display a message.

The example below shows how you can add some text to be displayed alongisde the loading spinner:

use AshAllenDesign\CommandSpinner\Traits\HasSpinner;

class YourCommand extends Command
{
    use HasSpinner;

    public function handle(): int
    {
        $this->withSpinner(function () {
            // Run your code here.
        }, 'Fetching data from API...');
    }
}

Customising the Spinner Type

The package comes with many types of loading spinners out of the box that you can use. To view all of the different possible loading spinners, check out the SpinnerType class.

The example below shows how you can choose a different spinner type:

use AshAllenDesign\CommandSpinner\Classes\SpinnerType;
use AshAllenDesign\CommandSpinner\Traits\HasSpinner;

class YourCommand extends Command
{
    use HasSpinner;

    public function handle(): int
    {
        $this->withSpinner(function () {
            // Run your code here.
        }, 'Fetching data from API...', SpinnerType::BLOCK_VARIANT_1);
    }
}

Examples

The below example shows you can use the PHP 8 named parameters to add a spinner to your command:

use AshAllenDesign\CommandSpinner\Classes\SpinnerType;
use AshAllenDesign\CommandSpinner\Traits\HasSpinner;

class YourCommand extends Command
{
    use HasSpinner;

    public function handle(): int
    {
        $this->withSpinner(
            closure: function () {
                $this->fetchDataFromAPI();
            },
            outputText: 'Fetching data from API...',
            spinnerType: SpinnerType::BLOCK_VARIANT_1
        );
    }
}

In the below example, let's imagine that we have a class that calculates something for us and returns it. So, we'll display a loading spinner while it's calculating and then output the result when it's returned.

use AshAllenDesign\CommandSpinner\Traits\HasSpinner;

class YourCommand extends Command
{
    use HasSpinner;

    public function handle(): int
    {
        $result = $this->withSpinner(function () {
            return (new Calculator)->calculate();
        });
        
        $this->line($result);
    }
}

Gotchas

Here's a list of a few gotchas that I'm currently aware of at the time of writing this:

This package's functionality is based on the spatie/fork package which is currently under active development. Therefore, it's possible that the functionality of this package may change if the fork package is updated before it's initial release.
Due to the fact that the package is based on the fork package, 2 child PHP processes are created for each spinner that is created. One of them handles the spinning animation, while the other executes the closure that is passed in. This means that because the closure is executed in a child process, it won't be able to directly change any data in the command class itself.
The withSpinner() method currently only allows for primitive types to be returned. Therefore, you can't currently return objects.
