PHP Luminova: Nova-Kit Command Patterns and Integrations
Need to manage environment variables or create a sitemap? NovaKit has got you covered. Perform database operations, execute scripts, or start a development server seamlessly—all from the command line.
The Luminova framework includes NovaKit, a Command Line Utility Tool designed to simplify application development. This tool allows for the extension and implementation of custom command-line logic tailored to your application's needs through the Base Command Class and Base Console
classes. By extending Base Command
, you can create command-line tools that operate similarly to HTTP Controller
methods, supporting command routing using Route Attributes.
What Is NovaKit?
NovaKit is a powerful tool provided by the Luminova framework to simplify command-line operations. It facilitates the development of console-level tools that can be executed directly as novakit
commands. NovaKit offers various functionalities, including:
- Generating boilerplate code.
- Creating scaffolds and templates.
- Managing environment variables.
- Handling database operations like migration, versioning and seeding.
- Managing application logs.
- Executing cron tasks on production environment.
- Running a PHP development server.
- And more.
Listing Available NovaKit Commands
To display the list of available NovaKit commands, open your command line tool, navigate to your project directory where the novakit
file is located, and run:
php novakit list
Novakit Help Command
To show general help information related to novakit
commands.
Print novakit
help information.
php novakit --help
Print help all novakit
commands help information.
php novakit --help --all
To print help information related to a specific novakit
command.
php novakit log --help
Basic NovaKit Generators Commands
The generator commands allow you to easily generate a skeleton for a controller class, utils class, or a view file.
Utils Class
To create a utility class for your application use the below example command.The class will be saved in /app/Utils/
php novakit create:class "myClass" --extend "baseClassName" --implement "myClassInterface"
Model Class
To create a database model class for your application use the below example command.The class will be saved in /app/Models/
php novakit create:model "myModel"
Controllers
To create a new controller class for your application use the below example command.The class will be saved in /app/Controllers/
php novakit create:controller 'PayStackController' --type 'view'
You can pass the type of
API
to extend\Luminova\Base\BaseController
orview
to extend\Luminova\Base\BaseViewController
.For command controller class extend and implement will ignore, use flag
--type "command"
View File
To create a utility class for your application use the below example command.The class will be saved in /resources/views/
php novakit create:view "blog"
To create a view file in a subdirectory in
/resources/views/
folder, use flag--dir "mySubDir"
Routing Context
To install a new routing context use the below example command.
php novakit context "test"'
The above command will create a file in
/routes/
directory and update your/public/index.php
with a new context.To disable adding an error handler in
index.php
use flag--no-error
Note: If the error handler is not disabled, you need to manually create the method name in your View errors class in
/app/Controllers/Errors/ViewErrors.php
.
Sitemap
To generate your website sitemap use the below command.
php novakit generate:sitemap
To configure the sitemap domain and ignore list, it can be done here
/app/Config/Sitemap.php
.
Application Cryptic Key
To generate your application encryption and decryption key use the below command.
php novakit generate:key
If you wish to generate without saving the key to env file, use flag
--no-save
.
Add/Update Environment Variables
To add new or update value to your env file use the below command.
php novakit env:add --key='my_new_key' --value='my key value'
If you wish to generate without saving the key to env file, use flag
--no-save
.
Remove Environment Variable
To remove key from your env file use the below command.
php novakit env:remove --key='my_old_key'
Build Exportable Project Files
To package your application for publishing, use the below command to archive the project files required for production.
php novakit build:project --type zip
Managing Application Log Files
To manage your application log files, you will need to specify the log level you want to view or manage.In this example we will be using debug
.
Display the 5 Most Recent Entries
To view the 5 most recent entries in the debug log:
php novakit log --level=debug
Display Log Entries Using offset and limit
To display debug log entries starting from line 5
and showing only the next 20
entries:
php novakit log --level=debug --start=5 --end=20
Clear the Entire Log File
To clear all entries from the debug log file:
php novakit log --level=debug --clear
Building Command Line Tools
Creating command-line tools in Luminova is straightforward, thanks to its intuitive routing system, which resembles HTTP routing. This familiarity makes it easy to apply known logic to your CLI commands.
Command Controllers
To create a new command controller in Luminova:
- Create Your Command Controller: Place your command controller classes in the
/app/Controllers/
directory, alongside your HTTP controller classes. Ensure these classes extendLuminova\Base\BaseCommand
. - Define Your Method: Use either PHP Attributes or code-based routing with the Router class methods for command implementations.
- Optional Help Display: Implement a command help display with styling and formatting as desired, or use the default display implementation.
Command Execution Pattern:
To execute a custom controller command, open your command line tool, navigate to your application's public directory with cd path/to/your-project/public
, and run the command following this pattern:
php index.php <group-name> <command-name> <arguments>
Print help information related to a command controller group.
php index.php <group-name> --help
The group-name
should be immediately after php index.php
, followed by the command-name
and any parameters. Arguments can be passed in any order after the command group name.
Routing Command Controllers
Example: Blog Command with Code-Based Routing
To define your commands using code-based routing, you can configure your routes in the routing file as follows:
// /routes/cli.php
<?php
$router->group('blog', static function(Router $router) {
// Command with argument
$router->command('list', 'BlogCommand::blogs');
// Command with method argument
$router->command('list/limit/(:int)', 'BlogCommand::blogs');
});
Example: Blog Command with Attribute-Based Routing
For attribute-based routing, you can directly annotate the blogs
method in your command class:
// app/Controllers/BlogCommand.php
<?php
namespace App\Controllers;
use Luminova\Base\BaseCommand;
class BlogCommand extends BaseCommand
{
// Command with argument
#[Route('list', group: 'blog')]
public function blogs(): int {
$limit = $this->getAnyOption('limit', 'l', 10);
echo $limit;
return STATUS_SUCCESS;
}
// Command with method argument
#[Route('list/limit/(:int)', group: 'blog')]
public function blogs(int $limit = 10): int {
echo $limit;
return STATUS_SUCCESS;
}
}
Note: Both implementations achieve the same result.
Executing Commands with Arguments
You can specify arguments for your commands in various ways. For example, to list blogs with a limit of 3:
php index.php blog list --limit=3
Displaying Command Help
To print help for the blog
command, use the following command:
php index.php blog --help
Catching Exceptions
In the Luminova framework, exceptions in CLI operations are managed effectively. To enable exception handling, follow these guidelines:
Enable Exception Handling
Environment Configuration:You can enable exception handling globally by setting the following option in your environment file:
throw.cli.exceptions = true
Temporary Enablement:If you want to enable exception handling temporarily for the current script execution, you can use the following global function. Call it before your script runs or within the controller's
__construct
,onCreate
, or any executing controller method:setenv('throw.cli.exceptions', 'true');
