Iris is a fast, simple yet fully featured and very efficient web framework for Go.

Iris provides a beautifully expressive and easy to use foundation for your next website or API.

Finally, a real expressjs equivalent for the Go Programming Language.

```sh
$ cat example.go
```

```go
package main

import "github.com/kataras/iris"

func main() {
    app := iris.New()
    // Load all templates from the "./views" folder
    // where extension is ".html" and parse them
    // using the standard `html/template` package.
    app.RegisterView(iris.HTML("./views", ".html"))

    // Method:    GET
    // Resource:  http://localhost:8080
    app.Get("/", func(ctx iris.Context) {
        // Bind: {{.message}} with "Hello world!"
        ctx.ViewData("message", "Hello world!")
        // Render template file: ./views/hello.html
        ctx.View("hello.html")
    })

    // Method:    GET
    // Resource:  http://localhost:8080/user/42
    //
    // Need to use a custom regexp instead?
    // Easy,
    // just mark the parameter's type to 'string'
    // which accepts anything and make use of
    // its `regexp` macro function, i.e:
    // app.Get("/user/{id:string regexp(^[0-9]+$)}")
    app.Get("/user/{id:long}", func(ctx iris.Context) {
        userID, _ := ctx.Params().GetInt64("id")
        ctx.Writef("User ID: %d", userID)
    })

    // Start the server using a network address.
    app.Run(iris.Addr(":8080"))
}
```

```html
<!-- file: ./views/hello.html -->
<html>
<head>
    <title>Hello Page</title>
</head>
<body>
    <h1>{{.message}}</h1>
</body>
</html>
```

```sh
$ go run example.go
Now listening on: http://localhost:8080
Application Started. Press CTRL+C to shut down.
_
```

## Installation

The only requirement is the [Go Programming Language](https://golang.org/dl/)

```sh
$ go get -u github.com/kataras/iris
```

Iris takes advantage of the [vendor directory](https://docs.google.com/document/d/1Bz5-UB7g2uPBdOx-rw5t9MxJwkfpx90cqG9AFL0JAYo) feature. You get truly reproducible builds, as this method guards against upstream renames and deletes.

## Learn

First of all, the most correct way to begin with a web framework is to learn the basics of the programming language and the standard `http` capabilities, if your web application is a very simple personal project without performance and maintainability requirements you may want to proceed just with the standard packages. After that follow the guidelines:

- Navigate through **100+1** **[examples](_examples)** and some [iris starter kits](#iris-starter-kits) we crafted for you
- Read the [godocs](https://godoc.org/github.com/kataras/iris) for any details
- Prepare a cup of coffee or tea, whatever pleases you the most, and read some [articles](#articles) we found for you

### Middleware

Iris has a great collection of handlers[[1]](middleware/)[[2]](https://github.com/iris-contrib/middleware) that you can use side by side with your web apps. However you are not limited to them - you are free to use any third-party middleware that is compatible with the [net/http](https://golang.org/pkg/net/http/) package, [_examples/convert-handlers](_examples/convert-handlers) will show you the way.

Iris, unlike others, is 100% compatible with the standards and that's why the majority of the big companies that adapt Go to their workflow, like a very famous US Television Network, trust Iris; it's always up-to-date and it will be aligned with the std `net/http` package which is modernized by the Go Author on each new release of the Go Programming Language forever.
