AdonisJs allows you to define reference to an existing value inside the config files. For example.

// config/app.js

module.exports = {
   appKey: Env.get('APP_KEY')
}

Now you can make use of the above value inside any other config file using the following syntax.

// config/auth.js

module.exports = {
   jwt: {
     secret: 'self::app.appKey'
   }
}

In order to resolve self references, each Config.get call has to recursively parse the return value and make sure all references to self are resolved.

This behavior causes an unnecessary performance overhead, without any major gains.

[email protected] has marked this behavior as depreciated and will be removed in another minor release of the framework ( 4.1.0 ).
