It not only makes the system secure but also robust to handle the request and response system efficiently.

Security – Slim comes with a flexible router system which routes the calls and requests to different HTTP methods through independent secure channels. You can pass through the parameters and authentic patterns effortlessly. This helps in creating URL with SEO keywords for better ranking. It also uses AES-256 encrypted cookies which makes it difficult for the hackers to use a fake cookie or fetch the original cookie in decoded condition.

If you are looking forward to creating REST API and allow third-party access to your web application, the Slim framework is the best choice for perfect and faster development with prototyping. Slim has a great logging system for errors and warnings. It is very easy to handle the errors and do proper debugging effortlessly.

New Concepts Introduced in Slim Framework –

You have to liberty to alter its default objects with third-party implementation. You can transform request and response objects with the library methods provided.

Middleware – A middleware is a new concept that exists in the Slim framework. It is created to manipulate the objects in Request and Response. This is going to protect your application for cross-site forged requests. Its layer of authentication completely surrounds your core application.

Dependency Container – While most of the frameworks use third-party containers like PHP-Di, Slim framework comes with a built-in dependency container. It is useful in maintaining all the operations of application dependencies efficiently.

Extra Components –
