	// Examples can be found at:
	Cache = cache.Handler
	// NoCache is a middleware which overrides the Cache-Control, Pragma and Expires headers
	// in order to disable the cache during the browser's back and forward feature.
	// A good use of this middleware is on HTML routes; to refresh the page even on "back" and "forward" browser's arrow buttons.

	NoCache = cache.NoCache
	// StaticCache middleware for caching static files by sending the "Cache-Control" and "Expires" headers to the client.
	// It accepts a single input parameter, the "cacheDur", a time.Duration that it's used to calculate the expiration.
	// If "cacheDur" <=0 then it returns the `NoCache` middleware instaed to disable the caching between browser's "back" and "forward" actions.
	// Usage: `app.Use(iris.StaticCache(24 * time.Hour))` or `app.Use(iris.StaticCache(-1))`.

	// for better performance.
	// Clients that are compatible with the http RCF (all browsers are and tools like postman)
	// will handle the caching.
	// The only disadvantage of using that instead of server-side caching
	// is that this method will send a 304 status code instead of 200,
	// So, if you use it side by side with other micro services
	// you have to check for that status code as well for a valid response.
	// Developers are free to extend this method's behavior
	// by watching system directories changes manually and use of the `ctx.WriteWithExpiration`
	// with a "modtime" based on the file modified date,

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 ""

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 *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) I18nReadOnly

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

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

func (*Application) Listen

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` 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 `` 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) 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 should be used to register view engines mapping to a root directory and the template file(s) extension.

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) 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) 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):// to http(s)://

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.


func (*Application) Validate

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):// will be redirect to http(s):// 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").

ExecutionRules gives control to the execution of the route handlers outside of the handlers themselves. Usage:

Party#SetExecutionRules(ExecutionRules {
  Done: ExecutionOptions{Force: true},

See `core/router/Party#SetExecutionRules` for more. Example:

type Filter

type Filter = context.Filter

Filter is just a type of func(Handler) bool which reports whether an action must be performed based on the incoming request.

See `NewConditionalHandler` for more. An alias for the `context/Filter`.

type Handler

type Handler = context.Handler

A Handler responds to an HTTP request. It writes reply headers and data to the Context.ResponseWriter() and then return. Returning signals that the request is finished; it is not valid to use the Context after or concurrently with the completion of the Handler call.

Depending on the HTTP client software, HTTP protocol version, and any intermediaries between the client and the iris server, it may not be possible to read from the Context.Request().Body after writing to the context.ResponseWriter(). Cautious handlers should read the Context.Request().Body first, and then reply.

Except for reading the body, handlers should not modify the provided Context.

If Handler panics, the server (the caller of Handler) assumes that the effect of the panic was isolated to the active request. It recovers the panic, logs a stack trace to the server error log, and hangs up the connection.

An alias for the `context.N`.

type Party

type Party = router.Party

Party is just a group joiner of routes which have the same prefix and share same middleware(s) also. Party could also be named as 'Join' or 'Node' or 'Group' , Party chosen because it is fun.

Look the `core/router#APIBuilder` for its implementation.

A shortcut for the `core/router#Party`, useful when `PartyFunc` is being used.

type Runner

type Runner func(*Application) error

Runner is just an interface which accepts the framework instance and returns an error.

It can be used to register a custom runner with `Run` in order to set the framework's server listen action.

Currently `Runner` is being used to declare the builtin server listeners.

See `Run` for more.

func Addr

func Addr(addr string, hostConfigs Runner

Addr can be used as an argument for the `Run` method. It accepts a host address which is used to build a server and a listener which listens on that host and port.

Addr should have the form of host:port, i.e localhost:8080 or :8080.

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: Look at the `ConfigureHost` too.

See `Run` for more.

func AutoTLS

func AutoTLS(
	addr string,
	domain string, email string,
	hostConfigs Runner

AutoTLS can be used as an argument for the `Run` method. It will start the Application's secure server using certifications created on the fly by the "autocert" golang/x package, so localhost may not be working, use it at "production" machine.

Addr should have the form of host:port, i.e

The whitelisted domains are separated by whitespace in "domain" argument, i.e "", 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: Look at the `ConfigureHost` too.

Usage: app.Run(iris.AutoTLS("", "", ""))

See `Run` and `core/host/Supervisor#ListenAndServeAutoTLS` for more.

Listener can be used as an argument for the `Run` method. It can start a server with a custom net.Listener via server's `Serve`.

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: Look at the `ConfigureHost` too.

See `Run` for more.

func Raw

func Raw(f func() error) Runner

Raw can be used as an argument for the `Run` method. It accepts any (listen) function that returns an error, this function should be block and return an error only when the server exited or a fatal error caused.

With this option you're not limited to the servers that iris can run by-default.

See `Run` for more.

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: Look at the `ConfigureHost` too.

See `Run` for more.

func TLS

func TLS(addr string, certFileOrContents, keyFileOrContents string, hostConfigs Runner

TLS can be used as an argument for the `Run` method. It will start the Application's secure server.

Use it like you used to use the http.ListenAndServeTLS function.

Addr should have the form of host:port, i.e localhost:443 or :443. "certFileOrContents" & "keyFileOrContents" should be filenames with their extensions or raw contents of the certificate and the private key.

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: Look at the `ConfigureHost` too.
