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

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

package main

import "github.com/kataras/iris/v12"

func main() {
  app := iris.New()
  app.Use(iris.Compression)

  app.Get("/", func(ctx iris.Context) {
    ctx.HTML("Hello <strong>%s</strong>!", "World")
  })

  app.Listen(":8080")
}

As one Go developer once said, Iris got you covered all-round and standing strong over the years.

Some of the features Iris offers:

  • HTTP/2 (Push, even Embedded data)
  • Middleware (Accesslog, Basicauth, CORS, gRPC, Anti-Bot hCaptcha, JWT, MethodOverride, ModRevision, Monitor, PPROF, Ratelimit, Anti-Bot reCaptcha, Recovery, RequestID, Rewrite)
  • API Versioning
  • Model-View-Controller
  • Websockets
  • gRPC
  • Auto-HTTPS
  • Builtin support for ngrok to put your app on the internet, the fastest way
  • Unique Router with dynamic path as parameter with standard types like :uuid, :string, :int... and the ability to create your own
  • Compression
  • View Engines (HTML, Django, Amber, Handlebars, Pug/Jade and more)
  • Create your own File Server and host your own WebDAV server
  • Cache
  • Localization (i18n, sitemap)
  • Sessions
  • Rich Responses (HTML, Text, Markdown, XML, YAML, Binary, JSON, JSONP, Protocol Buffers, MessagePack, Content Negotiation, Streaming, Server-Sent Events and more)
  • Response Compression (gzip, deflate, brotli, snappy, s2)
  • Rich Requests (Bind URL Query, Headers, Form, Text, XML, YAML, Binary, JSON, Validation, Protocol Buffers, MessagePack and more)
  • Dependency Injection (MVC, Handlers, API Routers)
  • Testing Suite
  • And the most important... you get fast answers and support from the 1st day until now - that's six full years!

Functions

func ConfigureMiddleware added in v12.2.0

func ConfigureMiddleware(handlers ...Handler) router.PartyConfigurator

ConfigureMiddleware is a PartyConfigurator which can be used as a shortcut to add middlewares on Party.PartyConfigure("/path", WithMiddleware(handler), new(example.API)).

func Minify added in v12.2.0

func Minify(ctx Context)

Minify is a middleware which minifies the responses based on the response content type. Note that minification might be slower, caching is advised. Customize the minifier through `Application.Minifier()`. Usage: app.Use(iris.Minify)

func PrefixDir added in v12.2.0

func PrefixDir(prefix string, fs http.FileSystem) http.FileSystem

PrefixDir returns a new FileSystem that opens files by adding the given "prefix" to the directory tree of "fs".

Useful when having templates and static files in the same bindata AssetFile method. This way you can select which one to serve as static files and what for templates. All view engines have a `RootDir` method for that reason too but alternatively, you can wrap the given file system with this `PrefixDir`.

Example: https://github.com/kataras/iris/blob/master/_examples/file-server/single-page-application/embedded-single-page-application/main.go

func PrefixFS added in v12.2.0

func PrefixFS(fileSystem fs.FS, dir string) (fs.FS, error)

APIContainer is a wrapper of a common `Party` featured by Dependency Injection. See `Party.ConfigureContainer` for more.

A shortcut for the `core/router#APIContainer`.

type Application

type Application struct {
	// routing embedded | exposing APIBuilder's and Router's public API.
	*router.APIBuilder
	*router.Router
	router.HTTPErrorHandler // if Router is Downgraded this is nil.

	// Users can wrap it to accept more events.
	OnBuild func() error

	// Hosts contains a list of all servers (Host Supervisors) that this app is running on.
	//
	// Hosts may be empty only if application ran(`app.Run`) with `iris.Raw` option runner,

	//
	// Additional Host Supervisors can be added to that list by calling the `app.NewHost` manually.
	//
	// Hosts field is available after `Run` or `NewHost`.
	Hosts []*host.Supervisor
	// contains filtered or unexported fields
}

Application is responsible to manage the state of the application. It contains and handles all the necessary parts to create a fast web server.

func Default

func Default() *Application

Default returns a new Application. Default with "debug" Logger Level. Localization enabled on "./locales" directory and HTML templates on "./views" or "./templates" directory. CORS (allow all), Recovery and Request ID middleware already registered.

func New

func New() *Application

New creates and returns a fresh empty iris *Application instance.

func (*Application) Build

func (app *Application) Build() error

Build sets up, once, the framework. It builds the default router with its default macros and the template functions that are very-closed to iris.

If error occurred while building the Application, the returns type of error will be an *errgroup.Group which let the callers to inspect the errors and cause, usage:

import "github.com/kataras/iris/v12/core/errgroup"

errgroup.Walk(app.Build(), func(typ interface{}, err error) {
	app.Logger().Errorf("%s: %s", typ, err)
})

func (*Application) ConfigurationReadOnly

func (app *Application) ConfigurationReadOnly() context.ConfigurationReadOnly

ConfigurationReadOnly returns an object which doesn't allow field writing.

func (*Application) Configure

func (app *Application) Configure(configurators ...Configurator) *Application

Configure can called when modifications to the framework instance needed. It accepts the framework instance and returns an error which if it's not nil it's printed to the logger. See configuration.go for more.

Returns itself in order to be used like `app:= New().Configure(...)`

func (*Application) ConfigureHost

func (app *Application) ConfigureHost(configurators ...host.Configurator) *Application

ConfigureHost accepts one or more `host#Configuration`, these configurators functions can access the host created by `app.Run` or `app.Listen`, they're being executed when application is ready to being served to the public.

It's an alternative way to interact with a host that is automatically created by `app.Run`.

These "configurators" can work side-by-side with the `iris#Addr, iris#Server, iris#TLS, iris#AutoTLS, iris#Listener` final arguments("hostConfigs") too.

Note that these application's host "configurators" will be shared with the rest of the hosts that this app will may create (using `app.NewHost`), meaning that `app.NewHost` will execute these "configurators" everytime that is being called as well.

These "configurators" should be registered before the `app.Run` or `host.Serve/Listen` functions.

func (*Application) GetContextErrorHandler added in v12.2.0

func (app *Application) GetContextErrorHandler() context.ErrorHandler

GetContextErrorHandler returns the handler which handles errors on JSON write failures.

func (*Application) GetContextPool added in v12.2.0

func (app *Application) GetContextPool() *context.Pool

GetContextPool returns the Iris sync.Pool which holds the contexts values. Iris automatically releases the request context, so you don't have to use it. It's only useful to manually release the context on cases that connection is hijacked by a third-party middleware and the http handler return too fast.

func (*Application) I18nReadOnly added in v12.1.0

func (app *Application) I18nReadOnly() context.I18nReadOnly

I18nReadOnly returns the i18n's read-only features. See `I18n` method for more.

func (*Application) IsDebug added in v12.2.0

func (app *Application) IsDebug() bool

IsDebug reports whether the application is running under debug/development mode. It's just a shortcut of Logger().Level >= golog.DebugLevel. The same method existss as Context.IsDebug() too.

func (*Application) Listen added in v12.1.7

func (app *Application) Listen(hostPort string, withOrWithout ...Configurator) error

Listen builds the application and starts the server on the TCP network address "host:port" which handles requests on incoming connections.

Listen always returns a non-nil error. Ignore specific errors by using an `iris.WithoutServerError(iris.ErrServerClosed)` as a second input argument.

Listen is a shortcut of `app.Run(iris.Addr(hostPort, withOrWithout...))`. See `Run` for details.

func (*Application) Logger

func (app *Application) Logger() *golog.Logger

Logger returns the golog logger instance(pointer) that is being used inside the "app".

Available levels: - "disable" - "fatal" - "error" - "warn" - "info" - "debug" Usage: app.Logger().SetLevel("error") Or set the level through Configurartion's LogLevel or WithLogLevel functional option. Defaults to "info" level.

Callers can use the application's logger which is the same `golog.Default.LastChild()` logger, to print custom logs too. Usage: app.Logger().Error/Errorf("...") app.Logger().Warn/Warnf("...") app.Logger().Info/Infof("...") app.Logger().Debug/Debugf("...")

Setting one or more outputs: app.Logger().SetOutput(io.Writer...) Adding one or more outputs : app.Logger().AddOutput(io.Writer...)

Adding custom levels requires import of the `github.com/kataras/golog` package:

First we create our level to a golog.Level
in order to be used in the Log functions.
var SuccessLevel golog.Level = 6
Register our level, just three fields.
golog.Levels[SuccessLevel] = &golog.LevelMetadata{
	Name:    "success",
	RawText: "[SUCC]",
	// ColorfulText (Green Color[SUCC])
	ColorfulText: "\x1b[32m[SUCC]\x1b[0m",
}

Usage: app.Logger().SetLevel("success") app.Logger().Logf(SuccessLevel, "a custom leveled log message")

func (*Application) Minifier added in v12.2.0

func (app *Application) Minifier() *minify.M

Minifier returns the minifier instance. By default it can minifies: - text/html - text/css - image/svg+xml - application/text(javascript, ecmascript, json, xml). Use that instance to add custom Minifiers before server ran.

func (*Application) NewHost

func (app *Application) NewHost(srv *http.Server) *host.Supervisor

NewHost accepts a standard *http.Server object, completes the necessary missing parts of that "srv" and returns a new, ready-to-use, host (supervisor).

func (*Application) RegisterView

func (app *Application) RegisterView(viewEngine view.Engine)

RegisterView registers a view engine for the application. Children can register their own too. If no Party view Engine is registered then this one will be used to render the templates instead.

func (*Application) Run

func (app *Application) Run(serve Runner, withOrWithout ...Configurator) error

Run builds the framework and starts the desired `Runner` with or without configuration edits.

Run should be called only once per Application instance, it blocks like http.Server.

If more than one server needed to run on the same iris instance then create a new host and run it manually by `go NewHost(*http.Server).Serve/ListenAndServe` etc... or use an already created host: h := NewHost(*http.Server) Run(Raw(h.ListenAndServe), WithCharset("utf-8"), WithRemoteAddrHeader("CF-Connecting-IP"))

The Application can go online with any type of server or iris's host with the help of the following runners: `Listener`, `Server`, `Addr`, `TLS`, `AutoTLS` and `Raw`.

func (*Application) SetContextErrorHandler added in v12.2.0

func (app *Application) SetContextErrorHandler(errHandler context.ErrorHandler) *Application

SetContextErrorHandler can optionally register a handler to handle and fire a customized error body to the client on JSON write failures.

ExampleCode:

 type contextErrorHandler struct{}
 func (e *contextErrorHandler) HandleContextError(ctx iris.Context, err error) {
	 errors.InvalidArgument.Err(ctx, err)
 }
 ...
	app.SetContextErrorHandler(new(contextErrorHandler))

func (*Application) SetName added in v12.2.0

func (app *Application) SetName(appName string) *Application

SetName sets a unique name to this Iris Application. It sets a child prefix for the current Application's Logger. Look `String` method too.

It returns this Application.

func (*Application) Shutdown

func (app *Application) Shutdown(ctx stdContext.Context) error

Shutdown gracefully terminates all the application's server hosts and any tunnels. Returns an error on the first failure, otherwise nil.

func (*Application) String added in v12.2.0

func (app *Application) String() string

String completes the fmt.Stringer interface and it returns the application's name. If name was not set by `SetName` or `IRIS_APP_NAME` environment variable then this will return an empty string.

func (*Application) SubdomainRedirect

func (app *Application) SubdomainRedirect(from, to router.Party) router.Party

SubdomainRedirect registers a router wrapper which redirects(StatusMovedPermanently) a (sub)domain to another subdomain or to the root domain as fast as possible, before the router's try to execute route's handler(s).

It receives two arguments, they are the from and to/target locations, 'from' can be a wildcard subdomain as well (app.WildcardSubdomain()) 'to' is not allowed to be a wildcard for obvious reasons, 'from' can be the root domain(app) when the 'to' is not the root domain and visa-versa.

Usage: www := app.Subdomain("www") <- same as app.Party("www.") app.SubdomainRedirect(app, www) This will redirect all http(s)://mydomain.com/%anypath% to http(s)://www.mydomain.com/%anypath%.

One or more subdomain redirects can be used to the same app instance.

If you need more information about this implementation then you have to navigate through the `core/router#NewSubdomainRedirectWrapper` function instead.

Example: https://github.com/kataras/iris/tree/master/_examples/routing/subdomains/redirect

func (*Application) Validate added in v12.2.0

func (app *Application) Validate(v interface{}) error

Validate validates a value and returns nil if passed or the failure reason if does not.

func (*Application) View

func (app *Application) View(writer io.Writer, filename string, layout string, bindingData interface{}) error

View executes and writes the result of a template file to the writer.

First parameter is the writer to write the parsed template. Second parameter is the relative, to templates directory, template filename, including extension. Third parameter is the layout, can be empty string. Forth parameter is the bindable data to the template, can be nil.

Use context.View to render templates to the client instead. Returns an error on failure, otherwise nil.

func (*Application) WWW

func (app *Application) WWW() router.Party

WWW creates and returns a "www." subdomain. The difference from `app.Subdomain("www")` or `app.Party("www.")` is that the `app.WWW()` method wraps the router so all http(s)://mydomain.com will be redirect to http(s)://www.mydomain.com. Other subdomains can be registered using the app: `sub := app.Subdomain("mysubdomain")`, child subdomains can be registered using the www := app.WWW(); www.Subdomain("wwwchildSubdomain").

type Attachments added in v12.2.0

type Attachments = router.Attachments

Attachments options for files to be downloaded and saved locally by the client. See `DirOptions`.

The whitelisted domains are separated by whitespace in "domain" argument, i.e "iris-go.com", can be different than "addr". If empty, all hosts are currently allowed. This is not recommended, as it opens a potential attack where clients connect to a server by IP address and pretend to be asking for an incorrect host name. Manager will attempt to obtain a certificate for that host, incorrectly, eventually reaching the CA's rate limit for certificate requests and making it impossible to obtain actual certificates.

For an "e-mail" use a non-public one, letsencrypt needs that for your own security.

Note: `AutoTLS` will start a new server for you which will redirect all http versions to their https, including subdomains as well.

Last argument is optional, it accepts one or more `func(*host.Configurator)` that are being executed on that specific host that this function will create to start the server. Via host configurators you can configure the back-end host supervisor, i.e to add events for shutdown, serve or error. An example of this use case can be found at: https://github.com/kataras/iris/blob/master/_examples/http-server/notify-on-shutdown/main.go Look at the `ConfigureHost` too.

Usage: app.Run(iris.AutoTLS("iris-go.com:443", "iris-go.com www.iris-go.com", "mail@example.com"))

See `Run` for more.

func Server

func Server(srv *http.Server, hostConfigs ...host.Configurator) Runner

Server can be used as an argument for the `Run` method. It can start a server with a *http.Server.

Second argument is optional, it accepts one or more `func(*host.Configurator)` that are being executed on that specific host that this function will create to start the server. Via host configurators you can configure the back-end host supervisor, i.e to add events for shutdown, serve or error. An example of this use case can be found at: https://github.com/kataras/iris/blob/master/_examples/http-server/notify-on-shutdown/main.go Look at the `ConfigureHost` too.

Last argument is optional, it accepts one or more `func(*host.Configurator)` that are being executed on that specific host that this function will create to start the server. Via host configurators you can configure the back-end host supervisor, i.e to add events for shutdown, serve or error. An example of this use case can be found at: https://github.com/kataras/iris/blob/master/_examples/http-server/notify-on-shutdown/main.go Look at the `ConfigureHost` too.
