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 micro 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!

Overview

• Hello world!
• Glimpse
• Tutorial: Online Visitors
• Tutorial: URL Shortener using BoltDB
• Tutorial: How to turn your Android Device into a fully featured Web Server

HTTP Listening

• Common, with address
  • omit server errors
• UNIX socket file
• TLS
• Letsencrypt (Automatic Certifications)
• Notify on shutdown
• Custom TCP Listener
  • common net.Listener
  • SO_REUSEPORT for unix systems
• Custom HTTP Server
  • easy way
  • std way
  • multi server instances
• Graceful Shutdown
  • using the RegisterOnInterrupt
  • using a custom notifier

Configuration

• Functional
• From Configuration Struct
• Import from YAML file
• Import from TOML file

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)

You can serve quicktemplate files too, simply by using the context#ResponseWriter, take a look at the http_responsewriter/quicktemplate example.

• OAUth2
• JWT
• Sessions

How to Read from context.Request() *http.Request

• Bind JSON
• Bind Form
• Upload/Read Files

The context.Request() returns the same *http.Request you already know, these examples show some places where the Context uses this object. Besides that you can use it as you did before iris.

How to Write to context.ResponseWriter() http.ResponseWriter

• Write valyala/quicktemplate templates
• Text, Markdown, HTML, JSON, JSONP, XML, Binary
• Stream Writer
• Transactions

The context.ResponseWriter() returns an enchament version of a http.ResponseWriter, these examples show some places where the Context uses this object. Besides that you can use it as you did before iris.

Miscellaneous

  • log requests to a file
• Localization and Internationalization
• Recovery
