Official Laravel package connecting your Manifold secrets into your Laravel application.

Introduction

The Manifold Laravel package allows you to connect to your Manifold account and pull your credentials, keys, configurations, etc. from your Manifold account into your Laravel application.

Installation

  1. Install the package
composer require manifoldco/manifold-laravel
  1. Publish the config file and select manifoldco\manifold-laravel from the vendor list.
php artisan vendor:publish
  1. Add, at the very least, your Manifold Bearer token to your .env file as follows: MANIFOLD_API_TOKEN=YOUR-TOKEN-HERE

  2. You may optionally specify a Project by providing the label in your .env file.

MANIFOLD_PROJECT=YOUR-PROJECT-LABEL

Usage

Once installed and configured, your project/resource credentials from Manifold will be pulled into your Laravel application as configurations. Your credentials can be accessed using the config helper, using the label of the resource and the key of credential, as they exist in Manifold, using dot-notation. For example, if you have a Mailgun resource setup with a credential named API_KEY, it can be accessed using config('mailgun.API_KEY') (where mailgun is the resource's label).

Note that keys are case sensitive. Also note that when configurations conflict with other Laravel configs, the Manifold configurations will take priority.

Aliases

In some cases, you may wish to use credentials from Manifold within configuration files (inside your /config directory). The most obvious use case would be database credentials that are needed within /config/database.php. Since you cannot reliably access configurations from within configuration files using the config() helper, aliases may be defined in your config/manifold.php file. Aliases can be defined in arrays (as with standard configurations) or using dot-notation for array keys. Define the existing config as the key and the Manifold credential as the value. For example, pulling a PostgreSQL password from a custom PostgreSQL service in Manifold could look like this: 'database.connections.pgsql.password' => 'custom-pgsql.DB_PASSWORD'. This will pull the DB_PASSWORD credential from the custom-pgsql resource and assign its value to database.connections.pgsql.password, so there is no need to manipulate your existing config/database.php file.

Examples

  1. You have a project in Manifold with a label of my-project. You want your Mailgun API key available in a controller method. Your Mailgun resource is named mailgun and the API key credential is API_KEY.

Add the following to .env

MANIFOLD_API_TOKEN=0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF0123456789AB
MANIFOLD_PROJECT=my-project

In your controller's php file:

class MyController extends Controller{
    public function process_mail(){

        $mailgun_key = config('mailgun.API_KEY');

        //mail processing logic here
    }
}
  1. You have a project in Manifold with a label of my-project. You want your PostgreSQL credentials from your custom service stored in Manifold. Your custom service is named custom-pgsql and the PostgreSQL credential keys are DB_HOST, DB_DATABASE, DB_USERNAME, and DB_PASSWORD.

Add the following to .env

MANIFOLD_API_TOKEN=0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF0123456789AB
MANIFOLD_PROJECT=my-project

In your config/manifold.php:

return [
    'token' => env('MANIFOLD_API_TOKEN', null),
    'project' => env('MANIFOLD_PROJECT', null),
    'aliases' => [
        /*
            note that while you can mix and match array syntax and dot-notation
            it's best to use one or the other, this merely illustrates that both
            are possible
        */
        'database.connections.pgsql.password' => 'custom-pgsql.DB_PASSWORD',
        'database' => [
            'connections' => [
                'pgsql' => [
                    'host' => 'custom-pgsql.DB_HOST',
                    'database' => 'custom-pgsql.DB_DATABASE',
                    'username' => 'custom-pgsql.DB_USERNAME',
                ]
            ]
        ]
    ],
];
  1. You have a project in Manifold with a label of my-project. You want your MySQL credentials from your JAWS stored in Manifold. Your JAWS service is named jaws-mysql and the connection credentials are in URL syntax as JAWSDB_URL. The URL syntax does not work with Laravel out of the box and must be parsed. For this you can pass a closure as the value of an alias. The closure receives no parameters, but all configs are loaded so you can access and Manifold stored credentials and manipulate them as necessary.

Add the following to .env

MANIFOLD_API_TOKEN=0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF0123456789AB
MANIFOLD_PROJECT=my-project

In your config/manifold.php:

return [
    'token' => env('MANIFOLD_API_TOKEN', null),
    'project' => env('MANIFOLD_PROJECT', null),
    'aliases' => [
        'database' => [
            'connections' => [
                'mysql' => [
                    'host' => function(){
                        $url = parse_url(config('custom-service.jaws'));
                        return $url['host'];
                    },
                    'password' => function(){
                        $url = parse_url(config('custom-service.jaws'));
                        return $url['pass'];
                    },
                    'username' => function(){
                        $url = parse_url(config('custom-service.jaws'));
                        return $url['user'];
                    },
                    'database' => function(){
                        $url = parse_url(config('custom-service.jaws'));
                        return substr($url["path"], 1);
                    }
                ]
            ]
        ]
    ],
];

Cautions

  1. Laravel's current process for loading config files it to load them alphabetically. This package relies on that feature to make sure configurations from your Manifold project are available within other configuration files. If you create a configuration file whose name comes alphabetically before the Manifold configuration files (00-manifold.php and 01-manifold.php), you may experience unexpected results. If Laravel changes it's load order, what for updates to this package.
  2. This package now uses the local file system to store API caches instead of Laravel's cache system, this is to allow the package to cache data from the API before the entire application is loaded (meaning before the Cache and Storage drivers are available). If you are in an environment where you cannot write to the local disk, you will not have caching features and every boot will require and API request. Similarly, if the user running the application does not have write permissions to storage/.manifold.cache.key you will not have caching features until this is remedied.
