The config directory, as the name implies, contains all of your application's configuration files. In this directory, you will find various files needed to configure database, session, mail, application, services etc.

Basic Configuration

  • After installing Laravel, the first thing we need to do is to set the write permission for the directory storage and bootstrap/cache.

  • Generate Application key to secure session and other encrypted data. If the root directory doesn’t contain the .env file then rename the .env.example to .env file and execute the following command where you have installed Laravel. The newly generated key can be seen in the .env file.

  • You can also configure the locale, time zone, etc. of the application in the config/app.php file.

Environmental Configuration

Laravel provides facility to run your application in different environment like testing, production etc. You can configure the environment of your application in the .env file of the root directory of your application. If you have installed Laravel using composer, this file will automatically be created.

In case you haven’t installed Laravel, you can simply rename the .env.example file to .env file. A sample of Laravel.env file is shown below.

Database Configuration

The database of your application can be configured from config/database.php file. You can set configuration parameters that can be used by different databases and you can also set the default one to use.

Naming the Application

The App Directory, by default, is namespaced under App. To rename it, you can execute the following command and rename the namespace.

Replace the <name-of-your-application> with the new name of your application that you want to give.
