How can you handle environment-specific configuration in Laravel deployment?

In Laravel, you can handle environment-specific configuration by utilizing the environment configuration files and the .env file. Here are the steps to handle environment-specific configuration in Laravel deployment:

1. Create a new environment-specific configuration file: Laravel allows you to create environment-specific configuration files in the config/ directory. For example, if you have a development environment, you can create a config/development directory and place the environment-specific configuration files inside it.
2. Copy the default configuration files: Inside the new environment-specific configuration directory, copy the configuration files from your config/ directory that need to be modified for the specific environment. Make any necessary changes to these files according to your environment.
3. Update the .env file: The .env file in the root directory of your Laravel project is used to store environment-specific variables. Update this file with the appropriate values for the environment you are deploying to. You can set variables like database credentials, API keys, etc. in this file.
4. Use environment-specific configuration files: In your application's bootstrap process, Laravel loads the configuration files based on the environment. By default, it loads the files from the default config/ directory. To load the environment-specific configuration, modify the bootstrap/app.php file and update the Application class instantiation to use the environment-specific configuration directory. For example:

1
2
3
4
5
6
7
8

$app = new Illuminate\Foundation\Application(
    realpath(__DIR__.'/../')
);

// Replace 'production' with environment-specific configuration directory
$app->useEnvironmentPath(__DIR__.'/../config/production');

// ...

1. Set environment variables on the server: When deploying your Laravel application, make sure to set the APP_ENV variable on your server to match the environment you are deploying to. This can be done via server configuration or using a service like .env file for server environment.

By following these steps, you can handle environment-specific configuration effectively in Laravel deployment.
