Laravel switch mysql to mongodb - php

Question

After completed my project I deiced switch mysql to mongodb. I am using Laravel 5.4 version and for mongodb use jenssegers. For laravel mongdb installation I follow jenssegers installation documentations and installation successfully completed. But after installation I go for migration and use command php artisan migrate. When I use this command shown error InvalidArgumentException in /vendor/mongodb/mongodb/src/Database.php line 83: $databaseName is invalid:
My database.php
'default' => env('DB_CONNECTION', 'mongodb'),
'connections' => [
'sqlite' => [
'driver' => 'sqlite',
'database' => env('DB_DATABASE', database_path('database.sqlite')),
'prefix' => '',
],
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
'pgsql' => [
'driver' => 'pgsql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '5432'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'prefix' => '',
'schema' => 'public',
'sslmode' => 'prefer',
],
'mongodb' => [
'driver' => 'mongodb',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', 27017),
'database' => env('DB_DATABASE', 'project_db'),
'username' => env('DB_USERNAME'),
'password' => env('DB_PASSWORD'),
'options' => [
'database' => 'admin' // sets the authentication database required by mongo 3
]
],
],
My .env
DB_CONNECTION=mongodb
DB_HOST=localhost
DB_PORT=27017
DB_DATABASE=admin
DB_USERNAME=
DB_PASSWORD=
And I also facing one more problem if whatever I change in .env and database.php like if I change port 27017 to 3303 but on browser shows 27017. I cleared cache and all. I don't know what is problem in my code.

These are the steps Envoyer (made by Laravel's creator) takes to deploy an app on production -- I've annotated them below:
# Clear the old boostrap/cache/compiled.php
php artisan clear-compiled
# Recreate boostrap/cache/compiled.php
php artisan optimize
# Migrate any database changes
php artisan migrate
