Examples
Please do learn how net/http std package works, first.
This folder provides easy to understand code snippets on how to get started with iris web framework.
It doesn't always contain the "best ways" but it does cover each important feature that will make you so excited to GO with iris!
Running the examples
- Install the Go Programming Language, version 1.12+ from https://golang.org/dl.
- Install Iris
- Install any external packages that required by the examples
External packages
cd _examples && go get ./...
And run each example you wanna see, e.g.
$ cd $GOPATH/src/github.com/kataras/iris/_examples/overview
$ go run main.go
Test the examples by opening a terminal window and execute:
go test -v ./...

Structuring
Nothing stops you from using your favorite folder structure. Iris is a low level web framework, it has got MVC first-class support but it doesn't limit your folder structure, this is your choice.
Structuring depends on your own needs. We can't tell you how to design your own application for sure but you're free to take a closer look to the examples below; you may find something useful that you can borrow for your app;
- Bootstrapper
- MVC with Repository and Service layer Overview
- Login (MVC with Single Responsibility package)
- Login (MVC with Datamodels, Datasource, Repository and Service layer)
HTTP Listening
- Common, with address
- UNIX socket file
- TLS
- Letsencrypt (Automatic Certifications)
- Notify on shutdown
- Custom TCP Listener
- Custom HTTP Server
- Graceful Shutdown
Configuration
Routing, Grouping, Dynamic Path Parameters, "Macros" and Custom Context
app.Get("{userid:int min(1)}", myHandler)app.Post("{asset:path}", myHandler)app.Put("{custom:string regexp([a-z]+)}", myHandler)
Note: unlike other routers you'd seen, iris' router can handle things like these:
// Matches all GET requests prefixed with "/assets/"
app.Get("/assets/{asset:path}", assetsWildcardHandler)
// Matches only GET "/"
app.Get("/", indexHandler)
// Matches only GET "/about"
app.Get("/about", aboutHandler)
// Matches all GET requests prefixed with "/profile/"
// and followed by a single path part
app.Get("/profile/{username:string}", userHandler)
// Matches only GET "/profile/me" because
// it does not conflict with /profile/{username:string}
// or the root wildcard {root:path}
app.Get("/profile/me", userHandler)
// Matches all GET requests prefixed with /users/
// and followed by a number which should be equal or bigger than 1
app.Get("/user/{userid:int min(1)}", getUserHandler)
// Matches all requests DELETE prefixed with /users/
// and following by a number which should be equal or bigger than 1
app.Delete("/user/{userid:int min(1)}", deleteUserHandler)
// Matches all GET requests except "/", "/about", anything starts with "/assets/" etc...
// because it does not conflict with the rest of the routes.
app.Get("{root:path}", rootWildcardHandler)

The httptest package is your way for end-to-end HTTP testing, it uses the httpexpect library created by our friend, gavv.
Caching
iris cache library lives on its own package.
- Simple
- Client-Side (304) - part of the iris context core
You're free to use your own favourite caching package if you'd like so.

Typescript Automation Tools
typescript automation tools have their own repository: https://github.com/kataras/iris/tree/master/typescript it contains examples
I'd like to tell you that you can use your favourite but I don't think you will find such a thing anywhere else.
Hey, You
Developers should read the godocs and https://docs.iris-go.com for a better understanding.
Psst, I almost forgot; do not forget to star or watch the project in order to stay updated with the latest tech trends, it never takes more than a second!

Package main shows how you can use the `WriteWithExpiration` based on the "modtime", if it's newer than the request header then it will refresh the contents, otherwise will let the client (99.9% the browser) to handle the cache mechanism, it's faster than iris.Cache because server-side has nothing to do and no need to store the responses in the memory.

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.

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.
