✨ Astrel Laravel

Integrate Astrel to your Laravel applications.

Astrel is a remote config orchestration application that enables you to change anything in your apps without touching your code.

🍿 Are you a visual learner? Here a quick video tutorial to help you get started with Astrel and Laravel.

Installation

Install this package via composer.

composer require sustainable-hustle/astrel-laravel

Add your Astrel API key in your .env file.

ASTREL_API_KEY="sxjTgBJAxkT2TNyKf9vabFI0L07AyItM5o3iiloS"

Finally, listen for Astrel's webhooks to clear the cache.

// routes/web.php
use SustainableHustle\Astrel\Facades\Astrel;
Astrel::webhookRoute('astrel/webhook');

// Make sure CSRF verification is disabled on that route.
class VerifyCsrfToken extends Middleware
{
    protected $except = [
        '/astrel/webhook',
    ];
}

Optionally, publish the astrel config file.

php artisan vendor:publish --tag="astrel-config"

Basic usage

This package provides a facade you can use to retrieve one or many aspects. An aspect is a key/value pair that you configure and updates directly on your Astrel dashboard.

use SustainableHustle\Astrel\Facades\Astrel;

Astrel::all();                        // Returns all aspects.
Astrel::get('slug');                  // Returns the value of an aspect by giving its slug.
Astrel::get('slug', 'default value'); // Returns the default value if the given aspect has no value.

Alternatively, you may use the astrel helper method to access the Astrel manager or to access a value directly.

astrel()->all();                 // Equivalent to Astrel::all();
astrel('slug');                  // Equivalent to Astrel::get('slug');
astrel('slug', 'default value'); // Equivalent to Astrel::get('slug', 'default value');

Note that if you'd like to fallback to an environment variable you may also use the astrel_env helper function like so.

astrel_env('my-slug');                           // Equivalent to astrel('my-slug', env('MY_SLUG'));
astrel_env('my-slug', 'MY_ENV_SLUG');            // Equivalent to astrel('my-slug', env('MY_ENV_SLUG'));
astrel_env('my-slug', 'MY_ENV_SLUG', 'default'); // Equivalent to astrel('my-slug', env('MY_ENV_SLUG', 'default'));

Caching

This package automatically caches all retrieved aspects. This ensure your application does not make API calls every single time a value from Astrel is required.

You may use the flush and refetch methods from the Astrel facade to clear the cache as well as refetching its content immediately.

use SustainableHustle\Astrel\Facades\Astrel;

Astrel::flush()   // Flush the cache for all aspects.
Astrel::refetch() // Flush the cache and refetch all aspects immediately.

By default, the cache never expires meaning you will have to manually flush it when necessary. This is because Astrel will send you a webhook whenever something changes so you can flush the cache only when necessary (see section below).

However, if you'd like to customize the cache's lifetime, you may update the cache_lifetime variable in your config/astrel.php file.

Clear the cache when receiving a webhook

As mentioned above, you can configure Astrel to send you a webhook whenever any value gets updated. That means you can use this webhook to clear and immediately refetch all of your aspects.

This package provides a helper method webhookRoute on the Astrel facade that does just that. Simply add this to your routes file and chain any route configuration you might like.

use SustainableHustle\Astrel\Facades\Astrel;

Astrel::webhookRoute();                 // Register a route that calls `Astrel::refetch()` when triggered.
Astrel::webhookRoute('astrel/webhook'); // Provide a custom path to that route.
Astrel::webhookRoute('astrel/webhook')  // This method returns a Route object so you can chain anything you want.
    ->name('webhooks.astrel')
    ->middleware('web');

Additionally, if you're using the default web middleware group, make sure to disable CSRF verification for that route in the VerifyCsrfToken middleware.

class VerifyCsrfToken extends Middleware
{
    protected $except = [
-       //
+      '/astrel/webhook',
    ];
}
