Laravel EnvClient
Manage and validate environmental variables with artisan console commands, environmental rules and facades

composer require lionix/envclient

  • To construct the \Lionix\Envclient use Laravel Service Container instead of plain construct.

Signature
Description
env:get {key}
Prints .env variable value
env:set {key} {value}
Sets .env variable if validation rules are passed
env:check
Check all env variables for validness
env:empty
Print empty .env variables
make:envrule {name}
Create a new .env validation rules

Set an environment variable using env:set artisan command.
php artisan env:set EXAMPLE_ENV_VARIABLE 'example value'
The command will modify your environment file by replacing or adding the given key to it.

If you want to apply validation rules to environmental variables before env:set command will modify the file you will have to publish command package configuration files.
php artisan vendor:publish --provider='Lionix\EnvClient\Providers\EnvClientServiceProvider' --tag='config'
The command will create config/env.php
return [
/**
* Validation classes which contain environment rules
* applied by env artisan commands.
*
* Add your validation classes created by
* `php artisan make:envrule` command to apply their rules
*
* @var array
*/
'rules' => [
\App\Env\BaseEnvValidationRules::class
]
];
and app/Env/BaseEnvValidationRules.php
namespace App\Env;
use Lionix\EnvValidator;
class BaseEnvValidationRules extends EnvValidator
{
/**
* Validation rules that apply to the .env variables.
*
* @return array
*/
public function rules() : array
{
return [
//
];
}
}
By adding validation rules into rules method return value you will apply them to env:set command.
...
public function rules() : array
{
return [
'DB_CONNECTION' => 'required|in:mysql,sqlite'
];
}
...
This way if you try to set an invalid value to the DB_CONNECTION variable with env:set command, the console will print out an error
$ php artisan env:set DB_CONNECTION SomeInvalidValue
The selected DB_CONNECTION is invalid.
If your environment file was modified you can run env:check command which will check all variables for validness and print out the results.
$ php artisan env:check
The selected DB_CONNECTION is invalid.

By default, the script will generate a class in App/Env namespace.

php artisan make:envrule DatabaseEnvRules
app/Env/DatabaseEnvRules.php
namespace App\Env;
use Lionix\EnvValidator;
class DatabaseEnvRules extends EnvValidator
{
/**
* Validation rules that apply to the .env variables.
*
* @return array
*/
public function rules() : array
{
return [
//
];
}
}

...
public function rules() : array
{
return [
'DB_CONNECTION' => 'requried|in:mysql,sqlite,pgsql,sqlsrv'
'DB_HOST' => 'requried',
'DB_PORT' => 'requried|numeric',
'DB_DATABASE' => 'requried',
'DB_USERNAME' => 'requried',
'DB_PASSWORD' => 'requried'
];
}
...

You can add the DatabaseEnvRules class to env.php configuration file at the rules key. That way all the rules specified in the class will affect package artisan commands.
config/env.php
return [
/**
* Validation classes which contain environment rules
* applied by env artisan commands.
*
* Add your validation classes created by
* `php artisan make:envrule` command to apply their rules
*
* @var array
*/
'rules' => [
\App\Env\BaseEnvValidationRules::class
\App\Env\DatabaseEnvRules::class // <- our database rules
]
];
Or you can use Lionix\EnvClient Facade to validate the input with given validation rules:
...
$client = app()->make(\Lionix\Envclient::class);
$client->useValidator(new \App\Env\DatabaseEnvRules())->update($databaseCredentials);
if ($client->errors()->isNotEmpty()) {
// handle errors
} else {
// success, the variables are updated
}
...
