Overview
package main
import (
"gopkg.in/kataras/iris.v6"
"gopkg.in/kataras/iris.v6/adaptors/httprouter"
"gopkg.in/kataras/iris.v6/adaptors/view"
)
func main() {
app := iris.New()
app.Adapt(iris.Devlogger()) // adapt a logger which prints all errors to the os.Stdout
app.Adapt(httprouter.New()) // adapt the adaptors/httprouter or adaptors/gorillamux
// 5 template engines are supported out-of-the-box:
//
// - standard html/template
// - amber
// - django
// - handlebars
// - pug(jade)
//
// Use the html standard engine for all files inside "./views" folder with extension ".html"
templates := view.HTML("./views", ".html")
app.Adapt(templates)
// http://localhost:6200
// Method: "GET"
// Render ./views/index.html
app.Get("/", func(ctx *iris.Context) {
ctx.Render("index.html", nil)
})
// Group routes, optionally: share middleware, template layout and custom http errors.
userAPI := app.Party("/users", userAPIMiddleware).
Layout("layouts/userLayout.html")
{
// Fire userNotFoundHandler when Not Found
// inside http://localhost:6200/users/*anything
userAPI.OnError(404, userNotFoundHandler)
// http://localhost:6200/users
// Method: "GET"
userAPI.Get("/", getAllHandler)
// http://localhost:6200/users/42
// Method: "GET"
userAPI.Get("/:id", getByIDHandler)
// http://localhost:6200/users
// Method: "POST"
userAPI.Post("/", saveUserHandler)
}
// Start the server at 127.0.0.1:6200
app.Listen(":6200")
}
func getByIDHandler(ctx *iris.Context) {
// take the :id from the path, parse to integer
// and set it to the new userID local variable.
userID, _ := ctx.ParamInt("id")
// userRepo, imaginary database service <- your only job.
user := userRepo.GetByID(userID)
// send back a response to the client,
// .JSON: content type as application/json; charset="utf-8"
// iris.StatusOK: with 200 http status code.
//
// send user as it is or make use of any json valid golang type,
// like the iris.Map{"username" : user.Username}.
ctx.JSON(iris.StatusOK, user)
}
TIP: Execute
iris run main.goto enable hot-reload on .go source code changes.

Philosophy
The Iris philosophy is to provide robust tooling for HTTP, making it a great solution for single page applications, web sites, hybrids, or public HTTP APIs. Keep note that, today, iris is faster than nginx itself.
Iris does not force you to use any specific ORM or template engine. With support for the most used template engines (6+), you can quickly craft the perfect application.

The Success of Iris belongs to YOU with your bug reports and feature requests that made this Framework so Unique.
Who is kataras?
Hi, my name is Gerasimos Maropoulos and I'm the author of this project, let me put a few words about me.
I started to design Iris the night of the 13 March 2016, some weeks later, iris started to became famous and I have to fix many issues and implement new features, but I didn't have time to work on Iris because I had a part time job and the (software engineering) colleague which I studied.
I wanted to make iris' users proud of the framework they're using, so I decided to interrupt my studies and colleague, two days later I left from my part time job also.
Today I spend all my days and nights coding for Iris, and I'm happy about this, therefore I have zero incoming value.
- Star the project, will help you to follow the upcoming features.
- Donate, if you can afford any cost.
- Write an article about Iris or even post a Tweet.
- Do Pull Requests on the iris-contrib organisation's repositories, like book and examples.
If you are interested in contributing to the Iris project, please see the document CONTRIBUTING.
