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 _examples/cookies/basic/main.go
```

```go
package main

import "github.com/kataras/iris"

func newApp() *iris.Application {
    app := iris.New()

    // Set A Cookie.
    app.Get("/cookies/{name}/{value}", func(ctx iris.Context) {
        name := ctx.Params().Get("name")
        value := ctx.Params().Get("value")

        ctx.SetCookieKV(name, value)

        ctx.Writef("cookie added: %s = %s", name, value)
    })

    // Retrieve A Cookie.
    app.Get("/cookies/{name}", func(ctx iris.Context) {
        name := ctx.Params().Get("name")

        value := ctx.GetCookie(name)

        ctx.WriteString(value)
    })

    // Delete A Cookie.
    app.Delete("/cookies/{name}", func(ctx iris.Context) {
        name := ctx.Params().Get("name")

        ctx.RemoveCookie(name)

        ctx.Writef("cookie %s removed", name)
    })

    return app
}

func main() {
    app := newApp()

    // GET:    http://localhost:8080/cookies/my_name/my_value
    // GET:    http://localhost:8080/cookies/my_name
    // DELETE: http://localhost:8080/cookies/my_name
    app.Run(iris.Addr(":8080"))
}
```

* Alternatively, use a regular `http.Cookie`: `ctx.SetCookie(&http.Cookie{...})`
* If you want to set custom the path: `ctx.SetCookieKV(name, value, iris.CookiePath("/custom/path/cookie/will/be/stored"))`.
* If you want to be available only to the current request path: `ctx.SetCookieKV(name, value, iris.CookieCleanPath /* or iris.CookiePath("") */)`
    * `iris.CookieExpires(time.Duration)`
    * `iris.CookieHTTPOnly(false)`
* `ctx.Request().Cookie(name)` is also available, it's the `net/http` approach

### Testing your Application? Easy with Iris

```go
package main

import (
    "fmt"
    "testing"

    "github.com/kataras/iris/httptest"
)

// go test -v -run=TestCookiesBasic$
func TestCookiesBasic(t *testing.T) {
    app := newApp()
    e := httptest.New(t, app, httptest.URL("http://example.com"))

    cookieName, cookieValue := "my_cookie_name", "my_cookie_value"

    // Test Set A Cookie.
    t1 := e.GET(fmt.Sprintf("/cookies/%s/%s", cookieName, cookieValue)).Expect().Status(httptest.StatusOK)
    t1.Cookie(cookieName).Value().Equal(cookieValue) // validate cookie's existence, it should be there now.
    t1.Body().Contains(cookieValue)

    path := fmt.Sprintf("/cookies/%s", cookieName)

    // Test Retrieve A Cookie.
    t2 := e.GET(path).Expect().Status(httptest.StatusOK)
    t2.Body().Equal(cookieValue)

    // Test Remove A Cookie.
    t3 := e.DELETE(path).Expect().Status(httptest.StatusOK)
    t3.Body().Contains(cookieName)

    t4 := e.GET(path).Expect().Status(httptest.StatusOK)
    t4.Cookies().Empty()
    t4.Body().Empty()
}
```

### Serve your Application

```sh
$ go run main.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 up-to-date and it will be always aligned with the std `net/http` package which is modernized by the Go Authors on each new release of the Go Programming Language.
