generates a .env.gen file based on the existing project source code. Analises for not used .env variables and variables used that are not defined on the .env file

Laravel Dot Env Generator

A Laravel 5 command that generates a .env.gen file containing all environment variables defined in .env as well as any undefined variables that are being used throughout the project.


Install the package using composer:

composer require mathiasgrimm/laravel-dot-env-gen:dev-master

Add the service provider:

// config/app.php

'providers' => [

Add .env.gen to your .gitignore


You can control which directories are scanned by providing exclusion rules in the dotenvgen.php config file. For a fresh Laravel install, we suggest that all subdirectories inside vendor are ignored except for vendor/laravel.

Publish the config file:

php artisan vendor:publish --provider="Vendor\Providers\DotEnvGenServiceProvider" --tag="config"

Example config:

// config/dotenvgen.php

'rules' => [
    // Ignores all files inside `vendor` except for those in `vendor/laravel`
    'vendor' => ['laravel'],

    // Ignores the `database/seeds` directory
    'database/seeds' => [],


From the command line, run php artisan env:gen.

A .env.gen file will be generated in your project's root folder. Make any changes you may need, then rename the file to .env.

Along with generating the .env.gen file, the command will notify you if a defined environment variable is unused as well as alert you if an undefined environment variable is being used.
