All the required configurations can be found in config folder and .env file.

.env file

Environment file can contain your confidential info, database credentials, api keys etc., because it is placed in .gitignore, therefore it will not be published on git, nor be publicaly available.
Properties inside are writted in the key=value way.

Using env function

So how are we suppose to use the .env file values? Global function env is used inside of configuration files in order to get the value from .env.

  "port": env('PORT', 3000),

When we try to get the port property from the config file, it will first try to get PORT key from .env file, if there isnt .env file, or the PORT key isnt set, second argument represents the default value, so the 3000 would be used instead.

To set the port value in the .env, it should look like


Get config value

Config service is used to get data from config files. You can access it by using its namespace use('Config');.
So lets say that we are looking for the application port. Path to that config value should be joined with . (dot).
First, we are looking for the file name where property is stored, and in this case, its app.js, we will only use the name of the file, without the extension.
After that, every level in config file object should be separated with dot.

Getting the port value:

let Config = use('Config');
let port = Config.get('app.port');

What if we have multiple levels like:

database.js > adapter > mysql > user

let Config = use('Config');
let user = Config.get('database.adapter.mysql.user');
