MVC Pattern

It’s true that Go developers are missing real MVC support. Net Core and Microsoft did an amazing job to provide that concepts into Production. Iris comes to do the same for Go developers, without the performance cost than .NET team had to sacrifice over it. Iris MVC and Dependency Injection feature is very powerful, giving you even more features and freedom than both Java EE and .NET Core provide today: bind services, models, request data, persistence data, sub controllers into your Controller’s fields and its methods. Hijack responses, requests, error handling per controller or per group of controllers.

Where the standard http.FileServer is not enough. Iris comes to complete the blank between simplicity and production-level file serving. With automatic HTTP/2 Index Assets Push. Support of Embedded files. In-memory cache of static assets like css, javascript and images. On-fly or cached compression based on client’s needs. You can rest by knowning your assets will be delivered as fast and safe as possible.
