| `undefinied iris.Context` | caused of using the **optional type alias**`iris.Context` instead of the `context.Context` when building with Go 1.8 | import the original package `github.com/kataras/iris/context` and declare as `func(context.Context){})`**or** download and install the [latest go version](https://golang.org/dl) |
Type alias is a new feature, introduced at Go version 1.9, so if you want to use Iris' type aliases you have to build using the latest Go version. Nothing really changes for your application if you use type alias or not, Iris' type aliases helps you to omit import statements -- to reduce lines of code, nothing more.
Go version 1.9 introduced the [type alias](https://golang.org/doc/go1.9#language) feature.
Iris uses the `type alias` feature to help you writing less code by omitting some package imports. The examples and documentation are written using Go 1.9 as well.
If you build your Go app with Go 1.9 you can, optionally, use all Iris web framework's features by importing one single package, the `github.com/kataras/iris`.
Available type aliases;
| Go 1.8 | Go 1.8 usage | Go 1.9 usage (optionally) |
Iris may have reached version 8, but we're not stopping there. We have many feature ideas on our board that we're anxious to add and other innovative web development solutions that we're planning to build into Iris.
