Should I upgrade my Iris?

Developers are not forced to upgrade if they don't really need it. Upgrade whenever you feel ready.

How to upgrade: Open your command-line and execute this command: go get github.com/kataras/iris/v12@latest.

This release introduces new features and some breaking changes inside the mvc and hero packages. The codebase for dependency injection has been simplified a lot (fewer LOCs and easier to read and follow up).

The new release contains a fresh new and awesome feature....a function dependency can accept previous registered dependencies and update or return a new value of any type.

The new implementation is faster on both design and serve-time.

The most common scenario from a route to handle is to:

accept one or more path parameters and request data, a payload
send back a response, a payload (JSON, XML,...)

The new Iris Dependency Injection feature is about 33.2% faster than its predecessor on the above case. This drops down even more the performance cost between native handlers and dynamic handlers with dependencies. This reason itself brings us, with safety and performance-wise, to the new Party.ConfigureContainer(builder ...func(*iris.APIContainer)) *APIContainer method which returns methods such as Handle(method, relativePath string, handlersFn ...interface{}) *Route and RegisterDependency.

Look how clean your codebase can be when using Iris':

package main

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

type (
    testInput struct {
        Email string `json:"email"`
    }

    testOutput struct {
        ID   int    `json:"id"`
        Name string `json:"name"`
    }
)

func handler(id int, in testInput) testOutput {
    return testOutput{
        ID:   id,
        Name: in.Email,
    }
}

func main() {
    app := iris.New()
    app.ConfigureContainer(func(api *iris.APIContainer) {
        api.Post("/{id:int}", handler)
    })
    app.Listen(":5000", iris.WithOptimizations)
}

Your eyes don't lie you. You read well, no ctx.ReadJSON(&v) and ctx.JSON(send) neither error handling are presented. It is a huge relief but if you ever need, you still have the control over those, even errors from dependencies. Here is a quick list of the new Party.ConfigureContainer()'s fields and methods:

// Container holds the DI Container of this Party featured Dependency Injection.
// Use it to manually convert functions or structs(controllers) to a Handler.
Container *hero.Container

// OnError adds an error handler for this Party's DI Hero Container and its handlers (or controllers).
// The "errorHandler" handles any error may occurred and returned
// during dependencies injection of the Party's hero handlers or from the handlers themselves.
OnError(errorHandler func(iris.Context, error))

// RegisterDependency adds a dependency.
// The value can be a single struct value or a function.
// Follow the rules:
// * <T> {structValue}
// * func(accepts <T>)                                 returns <D> or (<D>, error)
// * func(accepts iris.Context)                        returns <D> or (<D>, error)
//
// A Dependency can accept a previous registered dependency and return a new one or the same updated.
// * func(accepts1 <D>, accepts2 <T>)                  returns <E> or (<E>, error) or error
// * func(acceptsPathParameter1 string, id uint64)     returns <T> or (<T>, error)
//
// Usage:
//
// - RegisterDependency(loggerService{prefix: "dev"})
// - RegisterDependency(func(ctx iris.Context) User {...})
// - RegisterDependency(func(User) OtherResponse {...})
RegisterDependency(dependency interface{})

// UseResultHandler adds a result handler to the Container.
// A result handler can be used to inject the returned struct value
// from a request handler or to replace the default renderer.
UseResultHandler(handler func(next iris.ResultHandler) iris.ResultHandler)

ResultHandler

type ResultHandler func(ctx iris.Context, v interface{}) error

// Use same as a common Party's "Use" but it accepts dynamic functions as its "handlersFn" input.
Use(handlersFn ...interface{})
// Done same as a common Party's but it accepts dynamic functions as its "handlersFn" input.
Done(handlersFn ...interface{})

// Handle same as a common Party's `Handle` but it accepts one or more "handlersFn" functions which each one of them
// can accept any input arguments that match with the Party's registered Container's `Dependencies` and
// any output result; like custom structs <T>, string, []byte, int, error,
// a combination of the above, hero.Result(hero.View | hero.Response) and more.
//
// It's common from a hero handler to not even need to accept a `Context`, for that reason,
// the "handlersFn" will call `ctx.Next()` automatically when not called manually.
// To stop the execution and not continue to the next "handlersFn"
// the end-developer should output an error and return `iris.ErrStopExecution`.
Handle(method, relativePath string, handlersFn ...interface{}) *Route

// Get registers a GET route, same as `Handle("GET", relativePath, handlersFn....)`.
Get(relativePath string, handlersFn ...interface{}) *Route
// and so on...

Prior to this version the iris.Context was the only one dependency that has been automatically binded to the handler's input or a controller's fields and methods, read below to see what types are automatically binded:

Type	Maps To
*mvc.Application	Current MVC Application
iris.Context	Current Iris Context
*sessions.Session	Current Iris Session
context.Context	ctx.Request().Context()
*http.Request	`ctx.Request()`
http.ResponseWriter	`ctx.ResponseWriter()`
http.Header	`ctx.Request().Header`
time.Time	`time.Now()`
`string`,
`int, int8, int16, int32, int64`,
`uint, uint8, uint16, uint32, uint64`,
`float, float32, float64`,
`bool`,
`slice`	Path Parameter
Struct	Request Body of `JSON`, `XML`, `YAML`, `Form`, `URL Query`, `Protobuf`, `MsgPack`

Here is a preview of what the new Hero handlers look like:

Request & Response & Path Parameters

1. Declare Go types for client's request body and a server's response.

type (
	request struct {
		Firstname string `json:"firstname"`
		Lastname  string `json:"lastname"`
	}

	response struct {
		ID      uint64 `json:"id"`
		Message string `json:"message"`
	}
)

2. Create the route handler.

Path parameters and request body are binded automatically.

id uint64 binds to "id:uint64"
input request binds to client request data such as JSON

func updateUser(id uint64, input request) response {
	return response{
		ID:      id,
		Message: "User updated successfully",
	}
}

3. Configure the container per group and register the route.

app.Party("/user").ConfigureContainer(container)

func container(api *iris.APIContainer) {
    api.Put("/{id:uint64}", updateUser)
}

4. Simulate a client request which sends data to the server and displays the response.

curl --request PUT -d '{"firstanme":"John","lastname":"Doe"}' http://localhost:8080/user/42

{
    "id": 42,
    "message": "User updated successfully"
}

Custom Preflight

Before we continue to the next section, register dependencies, you may want to learn how a response can be customized through the iris.Context right before sent to the client.

The server will automatically execute the Preflight(iris.Context) error method of a function's output struct value right before send the response to the client.

Take for example that you want to fire different HTTP status codes depending on the custom logic inside your handler and also modify the value(response body) itself before sent to the client. Your response type should contain a Preflight method like below.

type response struct {
	ID      uint64 `json:"id,omitempty"`
	Message string `json:"message"`
	Code    int    `json:"code"`
	Timestamp int64 `json:"timestamp,omitempty"`
}

func (r *response) Preflight(ctx iris.Context) error {
	if r.ID > 0 {
		r.Timestamp = time.Now().Unix()
	}

	ctx.StatusCode(r.Code)
	return nil
}

Now, each handler that returns a *response value will call the response.Preflight method automatically.

func deleteUser(db *sql.DB, id uint64) *response {
    // [...custom logic]

    return &response{
        Message: "User has been marked for deletion",
        Code: iris.StatusAccepted,
    }
}

If you register the route and fire a request you should see an output like this, the timestamp is filled and the HTTP status code of the response that the client will receive is 202 (Status Accepted).

{
  "message": "User has been marked for deletion",
  "code": 202,
  "timestamp": 1583313026
}

Register Dependencies

1. Import packages to interact with a database. The go-sqlite3 package is a database driver for SQLite.

import "database/sql"
import _ "github.com/mattn/go-sqlite3"

2. Configure the container (see above), register your dependencies. Handler expects an *sql.DB instance.

localDB, _ := sql.Open("sqlite3", "./foo.db")
api.RegisterDependency(localDB)

3. Register a route to create a user.

api.Post("/{id:uint64}", createUser)

4. The create user Handler.

The handler accepts a database and some client request data such as JSON, Protobuf, Form, URL Query and e.t.c. It Returns a response.

func createUser(db *sql.DB, user request) *response {
    // [custom logic using the db]
    userID, err := db.CreateUser(user)
    if err != nil {
        return &response{
            Message: err.Error(),
            Code: iris.StatusInternalServerError,
        }
    }

	return &response{
		ID:      userID,
		Message: "User created",
		Code:    iris.StatusCreated,
	}
}

5. Simulate a client to create a user.

# JSON
curl --request POST -d '{"firstname":"John","lastname":"Doe"}' \
--header 'Content-Type: application/json' \
http://localhost:8080/user

# Form (multipart)
curl --request POST 'http://localhost:8080/users' \
--header 'Content-Type: multipart/form-data' \
--form 'firstname=John' \
--form 'lastname=Doe'

# Form (URL-encoded)
curl --request POST 'http://localhost:8080/users' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'firstname=John' \
--data-urlencode 'lastname=Doe'

# URL Query
curl --request POST 'http://localhost:8080/users?firstname=John&lastname=Doe'

Response:

{
    "id": 42,
    "message": "User created",
    "code": 201,
    "timestamp": 1583313026
}

Other Improvements:

gRPC features:
- New Router Wrapper.
- New MVC .Handle(ctrl, mvc.GRPC{...}) option which allows to register gRPC services per-party (without the requirement of a full wrapper) and optionally strict access to gRPC clients only, see the example here.
Improved tracing (with app.Logger().SetLevel("debug")) for routes. Example:

DBUG Routes (1)

DBUG Routes (2)

Fix #1552.
Proper listing of root directories on Party.HandleDir when its DirOptions.ShowList was set to true.
Socket Sharding as requested at #1544. New iris.WithSocketSharding Configurator and SocketSharding bool setting.
Versioned Controllers feature through the new mvc.Version option. See _examples/mvc/versioned-controller.
Fix #1539.
New rollbar example.
New builtin requestid middleware.
New builtin JWT middleware based on square/go-jose featured with optional encryption to set claims with sensitive data when necessary.
New iris.RouteOverlap route registration rule. Party.SetRegisterRule(iris.RouteOverlap) to allow overlapping across multiple routes for the same request subdomain, method, path. See 1536#issuecomment-643719922. This allows two or more MVC Controllers to listen on the same path based on one or more registered dependencies (see _examples/mvc/authenticated-controller).
Context.ReadForm now can return an iris.ErrEmptyForm instead of nil when the new Configuration.FireEmptyFormError is true (when iris.WithEmptyFormError is set) on missing form body to read from.
Configuration.EnablePathIntelligence | iris.WithPathIntelligence to enable path intelligence automatic path redirection on the most closest path (if any), [example]((https://github.com/kataras/iris/blob/master/_examples/routing/intelligence/main.go)
Enhanced cookie security and management through new Context.AddCookieOptions method and new cookie options (look on New Package-level functions section below), securecookie example has been updated.
Context.RemoveCookie removes also the Request's specific cookie of the same request lifecycle when iris.CookieAllowReclaim is set to cookie options, example.
iris.TLS can now accept certificates in form of raw []byte contents too.
iris.TLS registers a secondary http server which redirects "http://" to their "https://" equivalent requests, unless the new iris.TLSNoRedirect host Configurator is provided on iris.TLS (or iris.AutoTLS), e.g. app.Run(iris.TLS("127.0.0.1:443", "mycert.cert", "mykey.key", iris.TLSNoRedirect)).
Fix an issue about i18n loading from path which contains potential language code.
Server will not return neither log the ErrServerClosed error if app.Shutdown was called manually via interrupt signal(CTRL/CMD+C), note that if the server closed by any other reason the error will be fired as previously (unless iris.WithoutServerError(iris.ErrServerClosed)).
Finally, Log level's and Route debug information colorization is respected across outputs. Previously if the application used more than one output destination (e.g. a file through app.Logger().AddOutput) the color support was automatically disabled from all, including the terminal one, this problem is fixed now. Developers can now see colors in their terminals while log files are kept with clear text.
New iris.WithLowercaseRouting option which forces all routes' paths to be lowercase and converts request paths to their lowercase for matching.
New app.Validator { Struct(interface{}) error } field and app.Validate method were added. The app.Validator = can be used to integrate a 3rd-party package such as go-playground/validator. If set-ed then Iris Context's ReadJSON, ReadXML, ReadMsgPack, ReadYAML, ReadForm, ReadQuery, ReadBody methods will return the validation error on data validation failures. The read-json-struct-validation example was updated.
A result of can implement the new hero.PreflightResult interface which contains a single method of Preflight(iris.Context) error. If this method exists on a custom struct value which is returned from a handler then it will fire that Preflight first and if not errored then it will cotninue by sending the struct value as JSON(by-default) response body.
ctx.JSON, JSONP, XML: if iris.WithOptimizations is NOT passed on app.Run/Listen then the indentation defaults to " " (four spaces) and " " respectfully otherwise it is empty or the provided value.
Hero Handlers (and app.ConfigureContainer().Handle) do not have to require iris.Context just to call ctx.Next() anymore, this is done automatically now.
Improve Remote Address parsing as requested at: #1453. Add Configuration.RemoteAddrPrivateSubnets to exclude those addresses when fetched by Configuration.RemoteAddrHeaders through context.RemoteAddr() string.
Fix #1487.
Fix #1473.

New Package-level Variables:

iris.DirListRich to override the default look and feel if the DirOptions.ShowList was set to true, can be passed to DirOptions.DirList field.
iris.DirListRichOptions to pass on iris.DirListRich method.
iris.ErrGzipNotSupported to export the context.ErrGzipNotSupported when trying to write gzip but client does not support.
iris.GzipReader middleware to decode gzip requests on next read actions.
iris.B, KB, MB, GB, TB, PB, EB for byte units.
TLSNoRedirect to disable automatic "http://" to "https://" redirections (see below)
CookieAllowReclaim, CookieAllowSubdomains, CookieSameSite, CookieSecure and CookieEncoding to bring previously sessions-only features to all cookies in the request.

New Context Methods:

Context.Clone() Context returns a copy of the Context.
Context.IsCanceled() bool reports whether the request has been canceled by the client.
Context.IsSSL() bool reports whether the request is under HTTPS SSL (New Configuration.SSLProxyHeaders and HostProxyHeaders fields too).
Context.GzipReader(enable bool) method and iris.GzipReader middleware to enable future request read body calls to decompress data using gzip, example.
Context.RegisterDependency(v interface{}) and Context.UnregisterDependency(typ reflect.Type) to register/remove struct dependencies on serve-time through a middleware.
Context.SetID(id interface{}) and Context.GetID() interface{} added to register a custom unique indetifier to the Context, if necessary.
Context.GetDomain() string returns the domain.
Context.AddCookieOptions(...CookieOption) adds options for SetCookie, SetCookieKV, UpsertCookie and RemoveCookie methods for the current request.
Context.ClearCookieOptions() clears any cookie options registered through AddCookieOptions.
Context.SetLanguage(langCode string) force-sets a language code from inside a middleare, similar to the app.I18n.ExtractFunc
Context.ServeContentWithRate, ServeFileWithRate and SendFileWithRate methods to throttle the "download" speed of the client
Context.IsHTTP2() bool reports whether the protocol version for incoming request was HTTP/2
Context.IsGRPC() bool reports whether the request came from a gRPC client
Context.UpsertCookie(*http.Cookie, cookieOptions ...context.CookieOption) upserts a cookie, fixes #1485 too
Context.StopWithStatus(int) stops the handlers chain and writes the status code
Context.StopWithText(int, string) stops the handlers chain, writes thre status code and a plain text message
Context.StopWithError(int, error) stops the handlers chain, writes thre status code and the error's message
Context.StopWithJSON(int, interface{}) stops the handlers chain, writes the status code and sends a JSON response
Context.StopWithProblem(int, iris.Problem) stops the handlers, writes the status code and sends an application/problem+json response
Context.Protobuf(proto.Message) sends protobuf to the client (note that the Context.JSON is able to send protobuf as JSON)
Context.MsgPack(interface{}) sends msgpack format data to the client
Context.ReadProtobuf(ptr) binds request body to a proto message
Context.ReadJSONProtobuf(ptr, ...options) binds JSON request body to a proto message
Context.ReadMsgPack(ptr) binds request body of a msgpack format to a struct
Context.ReadBody(ptr) binds the request body to the "ptr" depending on the request's Method and Content-Type
Context.ReflectValue() []reflect.Value stores and returns the []reflect.ValueOf(ctx)
Context.Controller() reflect.Value returns the current MVC Controller value.

Breaking Changes:

Party.HandleDir now returns a list of []*Route (GET and HEAD) instead of GET only.
Context.OnClose and Context.OnCloseConnection now both accept an iris.Handler instead of a simple func() as their callback.
Context.StreamWriter(writer func(w io.Writer) bool) changed to StreamWriter(writer func(w io.Writer) error) error and it's now the Context.Request().Context().Done() channel that is used to receive any close connection/manual cancel signals, instead of the deprecated ResponseWriter().CloseNotify() one. Same for the Context.OnClose and Context.OnCloseConnection methods.
Fixed handler's error response not be respected when response recorder or gzip writer was used instead of the common writer. Fixes #1531. It contains a BREAKING CHANGE of: the new Configuration.ResetOnFireErrorCode field should be set to true in order to behave as it used before this update (to reset the contents on recorder or gzip writer).
Context.String() (rarely used by end-developers) it does not return a unique string anymore, to achieve the old representation you must call the new Context.SetID method first.
iris.CookieEncode and CookieDecode are replaced with the iris.CookieEncoding.
sessions#Config.Encode and Decode are removed in favor of (the existing) Encoding field.
versioning.GetVersion now returns an empty string if version wasn't found.
Change the MIME type of Javascript .js and JSONP as the HTML specification now recommends to "text/javascript" instead of the obselete "application/javascript". This change was pushed to the Go language itself as well. See https://go-review.googlesource.com/c/go/+/186927/.
Remove the last input argument of enableGzipCompression in Context.ServeContent, ServeFile methods. This was deprecated a few versions ago. A middleware (app.Use(iris.Gzip)) or a prior call to Context.Gzip(true) will enable gzip compression. Also these two methods and Context.SendFile one now support Content-Range and Accept-Ranges correctly out of the box (net/http had a bug, which is now fixed).
Context.ServeContent no longer returns an error, see ServeContentWithRate, ServeFileWithRate and SendFileWithRate new methods too.
route.Trace() string changed to route.Trace(w io.Writer), to achieve the same result just pass a bytes.Buffer
var mvc.AutoBinding removed as the default behavior now resolves such dependencies automatically (see [FEATURE REQUEST] MVC serving gRPC-compatible controller).
mvc#Application.SortByNumMethods() removed as the default behavior now binds the "thinnest" empty interface{} automatically (see MVC: service injecting fails).
mvc#BeforeActivation.Dependencies().Add should be replaced with mvc#BeforeActivation.Dependencies().Register instead
REMOVE the kataras/iris/v12/typescript package in favor of the new iris-cli. Also, the alm typescript online editor was removed as it is deprecated by its author, please consider using the designtsx instead.

Breaking Changes

Minor as many of you don't even use them but, indeed, they need to be covered here.

Old i18n middleware(iris/middleware/i18n) was replaced by the i18n sub-package which lives as field at your application: app.I18n.Load(globPathPattern string, languages ...string) (see below)
Community-driven i18n middleware(iris-contrib/middleware/go-i18n) has a NewLoader function which returns a loader which can be passed at app.I18n.Reset(loader i18n.Loader, languages ...string) to change the locales parser
The Configuration's TranslateFunctionContextKey was replaced by LocaleContextKey which Context store's value (if i18n is used) returns the current Locale which contains the translate function, the language code, the language tag and the index position of it
The context.Translate method was replaced by context.Tr as a shortcut for the new context.GetLocale().GetMessage(format, args...) method and it matches the view's function {{tr format args}} too
If you used Iris Django view engine with import _ github.com/flosch/pongo2-addons you must change the import path to _ github.com/iris-contrib/pongo2-addons or add a go mod replace to your go.mod file, e.g. replace github.com/flosch/pongo2-addons => github.com/iris-contrib/pongo2-addons v0.0.1.

Fixes

All known issues.

New Features

Internationalization and localization

Support for i18n is now a builtin feature and is being respected across your entire application, per say sitemap and views.

Refer to the wiki section: https://github.com/kataras/iris/wiki/Sitemap for details.

Sitemaps
