Learning Iris

Quick start
# assume the following code in example.go file
$ cat example.go
package main

import "github.com/radiantrfid/iris"

func main() {
    app := iris.Default()
    app.Get("/ping", func(ctx iris.Context) {
        ctx.JSON(iris.Map{
            "message": "pong",
        })
    })

    app.Run(iris.Addr(":8080"))
}
# run example.go and
# visit http://localhost:8080/ping on browser
$ go run example.go

Routing is powered by muxie, the most powerful and fastest trie-based software written in Go.

Iris contains extensive and thorough wiki making it easy to get started with the framework.

	// NoCache is a middleware which overrides the Cache-Control, Pragma and Expires headers

	// 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`

Functions

func WithTunneling

func WithTunneling(app *Application)

WithTunneling is the `iris.Configurator` for the `iris.Configuration.Tunneling` field. It's used to enable http tunneling for an Iris Application, per registered host

Alternatively use the `iris.WithConfiguration(iris.Configuration{Tunneling: iris.TunnelingConfiguration{ ...}}}`.

Types

type Application

type Application struct {
	// routing embedded | exposing APIBuilder's and Router's public API.
	*router.APIBuilder
	*router.Router
	ContextPool *context.Pool

	// 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,
	// otherwise it contains a single host (`app.Hosts[0]`).
	//
	// 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 instance which, unlike `New`, recovers on panics and logs the incoming http requests.

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.

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`, 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) 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") 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 `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) NewHost

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

NewHost accepts a standar *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. 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)://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/radiantrfid/iris/tree/master/_examples/subdomains/redirect

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").

See `core/router/Party#SetExecutionRules` for more. Example: https://github.com/radiantrfid/iris/tree/master/_examples/mvc/middleware/without-ctx-next

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.

type JSON

type JSON = context.JSON

JSON the optional settings for JSON renderer.

It is an alias of the `context#JSON` type.

type Map

type Map = context.Map

A Map is an alias of map[string]interface{}.

type N = context.N

N is a struct which can be passed on the `Context.Negotiate` method. It contains fields which should be filled based on the `Context.Negotiation()` server side values. If no matched mime then its "Other" field will be sent, which should be a string or []byte. It completes the `context/context.ContentSelector` interface.

An alias for the `context/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 Problem

type Problem = context.Problem

Problem Details for HTTP APIs. Pass a Problem value to `context.Problem` to write an "application/problem+json" response.

Read more at: https://github.com/radiantrfid/iris/wiki/Routing-error-handlers

It is an alias of the `context#Problem` type.

type ProblemOptions

type ProblemOptions = context.ProblemOptions

ProblemOptions the optional settings when server replies with a Problem. See `Context.Problem` method and `Problem` type for more details.

It is an alias of the `context#ProblemOptions` type.

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 ...host.Configurator) 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: https://github.com/radiantrfid/iris/blob/master/_examples/http-listening/notify-on-shutdown/main.go Look at the `ConfigureHost` too.

See `Run` for more.

func AutoTLS

func AutoTLS(
	addr string,
	domain string, email string,
	hostConfigs ...host.Configurator) 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 mydomain.com:443.

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/radiantrfid/iris/blob/master/_examples/http-listening/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` and `core/host/Supervisor#ListenAndServeAutoTLS` for more.

func Listener

func Listener(l net.Listener, hostConfigs ...host.Configurator) Runner

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: https://github.com/radiantrfid/iris/blob/master/_examples/http-listening/notify-on-shutdown/main.go 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.

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/radiantrfid/iris/blob/master/_examples/http-listening/notify-on-shutdown/main.go Look at the `ConfigureHost` too.

See `Run` for more.

func TLS

func TLS(addr string, certFile, keyFile string, hostConfigs ...host.Configurator) 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. CertFile & KeyFile should be filenames with their extensions.

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/radiantrfid/iris/blob/master/_examples/http-listening/notify-on-shutdown/main.go Look at the `ConfigureHost` too.

type Supervisor

type Supervisor = host.Supervisor

Supervisor is a shortcut of the `host#Supervisor`. Used to add supervisor configurators on common Runners without the need of importing the `core/host` package.

type Tunnel

type Tunnel struct {
	// Name is the only one required field,
	// it is used to create and close tunnels, e.g. "MyApp".
	// If this field is not empty then ngrok tunnels will be created
	// when the iris app is up and running.
	Name string `json:"name" yaml:"Name" toml:"Name"`
	// Addr is basically optionally as it will be set through
	// Iris built-in Runners, however, if `iris.Raw` is used
	// then this field should be set of form 'hostname:port'
	// because framework cannot be aware
	// of the address you used to run the server on this custom runner.
	Addr string `json:"addr,omitempty" yaml:"Addr" toml:"Addr"`
}

Tunnel is the Tunnels field of the TunnelingConfiguration structure.

type TunnelingConfiguration

type TunnelingConfiguration struct {
	// AuthToken field is optionally and can be used
	// to authenticate the ngrok access.
	// ngrok authtoken <YOUR_AUTHTOKEN>
	AuthToken string `json:"authToken,omitempty" yaml:"AuthToken" toml:"AuthToken"`

	// Bin is the system binary path of the ngrok executable file.
	// If it's empty then the framework will try to find it through system env variables.
	Bin string `json:"bin,omitempty" yaml:"Bin" toml:"Bin"`

	// WebUIAddr is the web interface address of an already-running ngrok instance.
	// Iris will try to fetch the default web interface address(http://127.0.0.1:4040)
	// to determinate if a ngrok instance is running before try to start it manually.
	// However if a custom web interface address is used,
	// this field must be set e.g. http://127.0.0.1:5050.
	WebInterface string `json:"webInterface,omitempty" yaml:"WebInterface" toml:"WebInterface"`

	// Region is optionally, can be used to set the region which defaults to "us".
	// Available values are:
	// "us" for United States
	// "eu" for Europe
	// "ap" for Asia/Pacific
	// "au" for Australia
	// "sa" for South America
	// "jp" forJapan
	// "in" for India
	Region string `json:"region,omitempty" yaml:"Region" toml:"Region"`

	// Tunnels the collection of the tunnels.
	// One tunnel per Iris Host per Application, usually you only need one.
	Tunnels []Tunnel `json:"tunnels" yaml:"Tunnels" toml:"Tunnels"`
}

TunnelingConfiguration contains configuration for the optional tunneling through ngrok feature. Note that the ngrok should be already installed at the host machine.

type UnmarshalerFunc

type UnmarshalerFunc = context.UnmarshalerFunc

UnmarshalerFunc a shortcut, an alias for the `context#UnmarshalerFunc` type which implements the `context#Unmarshaler` interface for reading request's body via custom decoders, most of them already implement the `context#UnmarshalerFunc` like the json.Unmarshal, xml.Unmarshal, yaml.Unmarshal and every library which follows the best practises and is aligned with the Go standards.

See 'context#UnmarshalBody` for more.

Example: https://github.com/radiantrfid/iris/blob/master/_examples/http_request/read-custom-via-unmarshaler/main.go

type XML

type XML = context.XML

XML the optional settings for XML renderer.

It is an alias of the `context#XML` type.

mvc/middleware/per-method
If you want to use it as middleware for the entire controller you can use its router which is just a sub router to add it as you normally do with standard API: I'll show you 4 different methods for adding a middleware into an mvc application, all of those 4 do exactly the same thing, select what you prefer, I prefer the last code-snippet when I need the middleware to be registered somewhere else as well, otherwise I am going with the first one: “`go // 1 mvc.Configure(app.Party("/user"), func(m *mvc.Application) { m.Router.Use(cache.Handler(10*time.Second)) }) “` “`go // 2 // same: userRouter := app.Party("/user") userRouter.Use(cache.Handler(10*time.Second)) mvc.Configure(userRouter, ...) “` “`go // 3 // same: userRouter := app.Party("/user", cache.Handler(10*time.Second)) mvc.Configure(userRouter, ...) “` “`go // 4 // same: app.PartyFunc("/user", func(r iris.Party){ r.Use(cache.Handler(10*time.Second)) mvc.Configure(r, ...) }) “` If you want to use a middleware for a single route, for a single controller's method that is already registered by the engine and not by custom `Handle` (which you can add the middleware there on the last parameter) and it's not depend on the `Next Handler` to do its job then you just call it on the method: “`go var myMiddleware := myMiddleware.New(...) // this should return an iris/context.Handler type UserController struct{} func (c *UserController) GetSomething(ctx iris.Context) { // ctx.Proceed checks if myMiddleware called `ctx.Next()` // inside it and returns true if so, otherwise false.

mvc/middleware/without-ctx-next
Package main is a simple example of the behavior change of the execution flow of the handlers, normally we need the `ctx.Next()` to call the next handler in a route's handler chain, but with the new `ExecutionRules` we can change this default behavior.
