iris is a web application framework written in Go.
Easy to learn, while it's highly customizable.
Its only sin?
To be the fastest web framework was ever published under open-source circumstances. Companies' offers were rejected, free forever.
Enjoy this framework now, without hesitation.
Quick Start
-----------
The only requirement is the [Go Programming Language](https://golang.org/dl), at least v1.7.
```bash
$ go get -u github.com/kataras/iris
```
> Production? Install the [stable version](https://github.com/kataras/iris/tree/4.0.0#versioning) instead
```bash
$ go get -u gopkg.in/kataras/iris.v4
```
### Hello, World!
```sh
$ cat helloworld.go
```
```go
package main
import "github.com/kataras/iris"
func main(){
iris.Get("/", func(c *iris.Context){
c.HTML(iris.StatusOK, "
Hello World!
")
})
iris.Listen(":8080")
}
```
```sh
$ go run helloworld.go
```
Open your browser at http://localhost:8080 and you should see the `Hello World!`.
### New
```go
// New with default configuration
app := iris.New()
app.Listen(....)
// New with configuration struct
app := iris.New(iris.Configuration{ DisablePathEscape: true})
app.Listen(...)
// Default station
iris.Listen(...)
// Default station with custom configuration
iris.Config.DisablePathEscape = true
iris.Listen(...)
```
### Listening
`Serve(ln net.Listener) error`
```go
ln, err := net.Listen("tcp4", ":8080")
if err := iris.Serve(ln); err != nil {
panic(err)
}
```
`Listen(addr string)`
```go
iris.Listen(":8080")
```
`ListenTLS(addr string, certFile, keyFile string)`
```go
iris.ListenTLS(":8080", "./ssl/mycert.cert", "./ssl/mykey.key")
```
`ListenLETSENCRYPT(addr string, cacheFileOptional ...string)`
```go
iris.ListenLETSENCRYPT("mydomain.com")
```
```go
iris.Serve(iris.LETSENCRYPTPROD("myproductionwebsite.com"))
```
And
```go
ListenUNIX(addr string, mode os.FileMode)
Close() error
Reserve() error
IsRunning() bool
```
### Routing
```go
iris.Get("/products/:id", getProduct)
iris.Post("/products", saveProduct)
iris.Put("products/:id", editProduct)
iris.Delete("/products/:id", deleteProduct)
```
And
```go
iris.Patch("", ...)
iris.Connect("", ...)
iris.Options("", ...)
iris.Trace("", ...)
```
### Path Parameters
```go
func getProduct(ctx *iris.Context){
// Get id from path '/products/:id'
id := ctx.Param("id")
}
```
### Query Parameters
`/details?color=blue&weight=20`
```go
func details(ctx *iris.Context){
color:= ctx.URLParam("color")
weight:= ctx.URLParamInt("weight")
}
```
### Form `application/x-www-form-urlencoded`
`METHOD: POST | PATH: /save`
name | value
:--- | :---
name | Gerasimos Maropoulos
email | kataras2006@homail.com
```go
func save(ctx *iris.Context) {
// Get name and email
name := ctx.FormValueString("name")
email := ctx.FormValueString("email")
}
```
### Form `multipart/form-data`
`POST` `/save`
name | value
:--- | :---
name | Gerasimos Maropoulos
email | kataras2006@hotmail.com
avatar | avatar
```go
func save(ctx *iris.Context) {
// Get name and email
name := ctx.FormValueString("name")
email := ctx.FormValueString("email")
// Get avatar
avatar, err := ctx.FormFile("avatar")
if err != nil {
ctx.EmitError(iris.StatusInternalServerError)
return
}
// Source
src, err := avatar.Open()
if err != nil {
ctx.EmitError(iris.StatusInternalServerError)
return
}
defer src.Close()
// Destination
dst, err := os.Create(avatar.Filename)
if err != nil {
ctx.EmitError(iris.StatusInternalServerError)
return
}
defer dst.Close()
// Copy
if _, err = io.Copy(dst, src); err != nil {
ctx.EmitError(iris.StatusInternalServerError)
return
}
ctx.HTML(iris.StatusOK, "Thanks!")
}
```
### Handling Request
- Bind `JSON` or `XML` or `form` payload into Go struct based on `Content-Type` request header.
- Render response as `JSON` or `XML` with status code.
```go
type User struct {
Name string `json:"name" xml:"name" form:"name"`
Email string `json:"email" xml:"email" form:"email"`
}
iris.Post("/users", func(ctx *iris.Context) {
u := new(User)
if err := ctx.ReadJSON(u); err != nil {
ctx.EmitError(iris.StatusInternalServerError)
return
}
ctx.JSON(iris.StatusCreated, u)
// or
// ctx.XML(iris.StatusCreated, u)
// ctx.JSONP(...)
// ctx.HTML(iris.StatusCreated, "Hi "+u.Name+"")
// ctx.Markdown(iris.StatusCreated, "## Name: "+u.Name)
})
```

### HTTP Errors
You can define your own handlers when http error occurs.
```go
package main
import (
"github.com/kataras/iris"
)
func main() {
iris.OnError(iris.StatusInternalServerError, func(ctx *iris.Context) {
ctx.Write("CUSTOM 500 INTERNAL SERVER ERROR PAGE")
// or ctx.Render, ctx.HTML any render method you want
ctx.Log("http status: 500 happened!")
})
iris.OnError(iris.StatusNotFound, func(ctx *iris.Context) {
ctx.Write("CUSTOM 404 NOT FOUND ERROR PAGE")
ctx.Log("http status: 404 happened!")
})
// emit the errors to test them
iris.Get("/500", func(ctx *iris.Context) {
ctx.EmitError(iris.StatusInternalServerError) // ctx.Panic()
})
iris.Get("/404", func(ctx *iris.Context) {
ctx.EmitError(iris.StatusNotFound) // ctx.NotFound()
})
iris.Listen(":80")
}
```
### Static Content
Serve files or directories, use the correct for your case, if you don't know which one, just use the `Static(relative string, systemPath string, stripSlashes int)`.
```go
// StaticHandler returns a HandlerFunc to serve static system directory
// Accepts 5 parameters
//
// first param is the systemPath (string)
// Path to the root directory to serve files from.
//
// second is the stripSlashes (int) level
// * stripSlashes = 0, original path: "/foo/bar", result: "/foo/bar"
// * stripSlashes = 1, original path: "/foo/bar", result: "/bar"
// * stripSlashes = 2, original path: "/foo/bar", result: ""
//
// third is the compress (bool)
// Transparently compresses responses if set to true.
//
// The server tries minimizing CPU usage by caching compressed files.
// It adds FSCompressedFileSuffix suffix to the original file name and
// tries saving the resulting compressed file under the new file name.
// So it is advisable to give the server write access to Root
// and to all inner folders in order to minimze CPU usage when serving
// compressed responses.
//
// fourth is the generateIndexPages (bool)
// Index pages for directories without files matching IndexNames
// are automatically generated if set.
//
// Directory index generation may be quite slow for directories
// with many files (more than 1K), so it is discouraged enabling
// index pages' generation for such directories.
//
// fifth is the indexNames ([]string)
// List of index file names to try opening during directory access.
//
// For example:
//
// * index.html
// * index.htm
// * my-super-index.xml
//
StaticHandler(systemPath string, stripSlashes int, compress bool,
generateIndexPages bool, indexNames []string) HandlerFunc
// Static registers a route which serves a system directory
// this doesn't generates an index page which list all files
// no compression is used also, for these features look at StaticFS func
// accepts three parameters
// first parameter is the request url path (string)
// second parameter is the system directory (string)
// third parameter is the level (int) of stripSlashes
// * stripSlashes = 0, original path: "/foo/bar", result: "/foo/bar"
// * stripSlashes = 1, original path: "/foo/bar", result: "/bar"
// * stripSlashes = 2, original path: "/foo/bar", result: ""
Static(relative string, systemPath string, stripSlashes int)
// StaticFS registers a route which serves a system directory
// generates an index page which list all files
// uses compression which file cache, if you use this method it will generate compressed files also
// think this function as small fileserver with http
// accepts three parameters
// first parameter is the request url path (string)
// second parameter is the system directory (string)
// third parameter is the level (int) of stripSlashes
// * stripSlashes = 0, original path: "/foo/bar", result: "/foo/bar"
// * stripSlashes = 1, original path: "/foo/bar", result: "/bar"
// * stripSlashes = 2, original path: "/foo/bar", result: ""
StaticFS(relative string, systemPath string, stripSlashes int)
// StaticWeb same as Static but if index.html e
// xists and request uri is '/' then display the index.html's contents
// accepts three parameters
// first parameter is the request url path (string)
// second parameter is the system directory (string)
// third parameter is the level (int) of stripSlashes
// * stripSlashes = 0, original path: "/foo/bar", result: "/foo/bar"
// * stripSlashes = 1, original path: "/foo/bar", result: "/bar"
// * stripSlashes = 2, original path: "/foo/bar", result: ""
StaticWeb(relative string, systemPath string, stripSlashes int)
// StaticServe serves a directory as web resource
// it's the simpliest form of the Static* functions
// Almost same usage as StaticWeb
// accepts only one required parameter which is the systemPath
// (the same path will be used to register the GET&HEAD routes)
// if the second parameter is empty, otherwise the requestPath is the second parameter
// it uses gzip compression (compression on each request, no file cache)
StaticServe(systemPath string, requestPath ...string)
```
```go
iris.Static("/public", "./static/assets/", 1)
//-> /public/assets/favicon.ico
```
```go
iris.StaticFS("/ftp", "./myfiles/public", 1)
```
```go
iris.StaticWeb("/","./my_static_html_website", 1)
```
```go
StaticServe(systemPath string, requestPath ...string)
```
#### Manual static file serving
```go
// ServeFile serves a view file, to send a file
// to the client you should use the SendFile(serverfilename,clientfilename)
// receives two parameters
// filename/path (string)
// gzipCompression (bool)
//
// You can define your own "Content-Type" header also, after this function call
ServeFile(filename string, gzipCompression bool) error
```
Serve static individual file
```go
iris.Get("/txt", func(ctx *iris.Context) {
ctx.ServeFile("./myfolder/staticfile.txt", false)
}
```
### Templates
**HTML Template Engine, defaulted**
```html
Hi Iris
Hi {{.Name}}
```
```go
// file ./main.go
package main
import "github.com/kataras/iris"
func main() {
iris.Config.IsDevelopment = true // this will reload the templates on each request
iris.Get("/hi", hi)
iris.Listen(":8080")
}
func hi(ctx *iris.Context) {
ctx.MustRender("hi.html", struct{ Name string }{Name: "iris"})

### Sessions
If you notice a bug or issue [post it here](https://github.com/kataras/go-sessions).
- Cleans the temp memory when a session is idle, and re-allocates it to the temp memory when it's necessary.
The most used sessions are optimized to be in the front of the memory's list.
- Supports any type of database, currently only [Redis](https://github.com/kataras/go-sessions/tree/master/sessiondb/redis) and [LevelDB](https://github.com/kataras/go-sessions/tree/master/sessiondb/leveldb).
**A session can be defined as a server-side storage of information that is desired to persist throughout the user's interaction with the web application**.
Instead of storing large and constantly changing data via cookies in the user's browser (i.e. CookieStore),
**only a unique identifier is stored on the client side** called a "session id".
This session id is passed to the web server on every request.
The web application uses the session id as the key for retrieving the stored data from the database/memory. The session data is then available inside the iris.Context.
```go
iris.Get("/", func(ctx *iris.Context) {
ctx.Write("You should navigate to the /set, /get, /delete, /clear,/destroy instead")
})
iris.Get("/set", func(ctx *iris.Context) {
//set session values
ctx.Session().Set("name", "iris")
//test if setted here
ctx.Write("All ok session setted to: %s", ctx.Session().GetString("name"))
})
iris.Get("/get", func(ctx *iris.Context) {
// get a specific key as a string.
// returns an empty string if the key was not found.
name := ctx.Session().GetString("name")
ctx.Write("The name on the /set was: %s", name)
})
iris.Get("/delete", func(ctx *iris.Context) {
// delete a specific key
ctx.Session().Delete("name")
})
iris.Get("/clear", func(ctx *iris.Context) {
// removes all entries
ctx.Session().Clear()
})
iris.Get("/destroy", func(ctx *iris.Context) {
// destroy/removes the entire session and cookie
ctx.SessionDestroy()
ctx.Log("You have to refresh the page to completely remove the session (on browsers), so the name should NOT be empty NOW, is it?\n ame: %s\n\nAlso check your cookies in your browser's cookies, should be no field for localhost/127.0.0.1 (or whatever you use)", ctx.Session().GetString("name"))
ctx.Write("You have to refresh the page to completely remove the session (on browsers), so the name should NOT be empty NOW, is it?\nName: %s\n\nAlso check your cookies in your browser's cookies, should be no field for localhost/127.0.0.1 (or whatever you use)", ctx.Session().GetString("name"))
})
iris.Listen(":8080")

Support
------------
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
- [Donate](https://github.com/kataras/iris/blob/master/DONATIONS.md)
- :earth_americas: spread the word
- [Contribute](#contributing) to the project
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, you can quickly craft the perfect application.
Benchmarks
------------
This Benchmark test aims to compare the whole HTTP request processing between Go web frameworks.
**The results have been updated on July 21, 2016**
The second is an article I just found(**3 October 2016**) which compares Iris vs Nginx vs Nodejs express, it was written in Thai, so I used google to translate it to english.
The results showed that the req / sec iris do best at around 70k-50k, followed by nginx and nginx-php-fpm and nodejs respectively.
The error golang-iris and nginx work equally, followed by the final nginx and php-fpm at a ratio of 1: 1.
You can read the full article [here](https://translate.google.com/translate?sl=auto&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=http://webcache.googleusercontent.com/search?q=cache:https%3A%2F%2Fwww.ntossapo.me%2F2016%2F08%2F13%2Fnginx-vs-nginx-php-fpm-vs-go-iris-vs-express-with-wrk%2F&edit-text=&act=url).
Testing
