🚀 Installation
The only requirement is the Go Programming Language, at least version 1.8
$ go get -u github.com/kataras/iris
iris takes advantage of the vendor directory feature. You get truly reproducible builds, as this method guards against upstream renames and deletes.
// file: main.go
package main
import (
"github.com/kataras/iris"
"github.com/kataras/iris/context"
)
func main() {
app := iris.New()
// Load all templates from the "./templates" folder
// where extension is ".html" and parse them
// using the standard `html/template` package.
app.RegisterView(iris.HTML("./templates", ".html"))
// Method: GET
// Resource: http://localhost:8080
app.Get("/", func(ctx context.Context) {
// Bind: {{.message}} with "Hello world!"
ctx.ViewData("message", "Hello world!")
// Render template file: ./templates/hello.html
ctx.View("hello.html")
})
// Start the server using a network address and block.
app.Run(iris.Addr(":8080"))
}
<!-- file: ./templates/hello.html -->
<html>
<head>
<title>Hello Page</title>
</head>
<body>
<h1>{{.message}}</h1>
</body>
</html>
$ go run main.go
> Now listening on: http://localhost:8080
> Application started. Press CTRL+C to shut down.
Hello World with Go 1.9
If you've installed Go 1.9 then you can omit the github.com/kataras/iris/context package from the imports statement.
// +build go1.9
package main
import "github.com/kataras/iris"
func main() {
app := iris.New()
app.RegisterView(iris.HTML("./templates", ".html"))
app.Get("/", func(ctx iris.Context) {
ctx.ViewData("message", "Hello world!")
ctx.View("hello.html")
})
app.Run(iris.Addr(":8080"))
}
We expect Go version 1.9 to be released in August, however you can install Go 1.9 beta today.
Installing Go 1.9beta2
- Go to https://golang.org/dl/#go1.9beta2
- Download a compatible, with your OS, archieve, i.e
go1.9beta2.windows-amd64.zip - Unzip the contents of
go1.9beta2.windows-amd64.zip/gofolder to your $GOROOT, i.eC:\Go - Open a terminal and execute
go version, it should output the go1.9beta2 version, i.e:
C:\Users\hiveminded>go version
go version go1.9beta2 windows/amd64
Why a new web framework
Why
Go is a great technology stack for building scalable, web-based, back-end systems for web applications.
When you think about building web applications and web APIs, or simply building HTTP servers in Go, does your mind go to the standard net/http package? Then you have to deal with some common situations like dynamic routing (a.k.a parameterized), security and authentication, real-time communication and many other issues that net/http doesn't solve.
The net/http package is not complete enough to quickly build well-designed back-end web systems. When you realize this, you might be thinking along these lines:
- Ok, the net/http package doesn't suit me, but there are so many frameworks, which one will work for me?!
- Each one of them tells me that it is the best. I don't know what to do!
The truth
I did some deep research and benchmarks with 'wrk' and 'ab' in order to choose which framework would suit me and my new project. The results, sadly, were really disappointing to me.
I started wondering if golang wasn't as fast on the web as I had read... but, before I let Golang go and continued to develop with nodejs, I told myself:
'Makis, don't lose hope, give at least a chance to Golang. Try to build something totally new without basing it off the "slow" code you saw earlier; learn the secrets of this language and make others follow your steps!'.
These are the words I told myself that day [13 March 2016].
The same day, later the night, I was reading a book about Greek mythology. I saw an ancient goddess' name and was inspired immediately to give a name to this new web framework (which I had already started writing) - Iris.
I'm still here because Iris has succeed in being the fastest go web framework
iris is easy, it has a familiar API while in the same has far more features than Gin or Martini.
You own your code —it will never generate (unfamiliar) code for you, like Beego, Revel and Buffalo do.
It's not just-another-router but its overall performance is equivalent with something like httprouter.
Unlike fasthttp, iris provides full HTTP/2 support for free.
Compared to the rest open source projects, this one is very active and you get answers almost immediately.

📖 Learn
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 apache+nginx itself.
iris does not force you to use any specific ORM. With support for the most popular template engines, websocket server and a fast sessions manager you can quickly craft your perfect application.
The awesome iris community is always adding new examples, _examples is a great place to get started!
Read the godocs for a better understanding.

📌 Version
Current: 8.0.4
Each new release is pushed to the master. It stays there until the next version. When a next version is released then the previous version goes to its own branch with gopkg.in as its import path (and its own vendor folder), in order to keep it working "for-ever".
Changelog of the current version can be found at the HISTORY file.
Should I upgrade my iris?
Developers are not forced to use the latest iris version, they can use any version in production, they can update at any time they want.
Testers should upgrade immediately, if you're willing to use iris in production you can wait a little more longer, transaction should be as safe as possible.
Where can I find older versions?
Previous versions can be found at releases page.
