Iris Web Framework

build status report card vscode-iris chat view examples release

Iris is a fast, simple yet fully featured and very efficient web framework for Go.

Finally, a real expressjs equivalent for the Go Programming Language.

$ cat example.go
package main

import ""

func main() {
    app := iris.New()
    // Load all templates from the "./views" folder
    // where extension is ".html" and parse them
    // using the standard `html/template` package.
    app.RegisterView(iris.HTML("./views", ".html"))

    // Method:    GET
    // Resource:  http://localhost:8080
    app.Get("/", func(ctx iris.Context) {
        // Bind: {{.message}} with "Hello world!"
        ctx.ViewData("message", "Hello world!")
        // Render template file: ./views/hello.html

    // Method:    GET
    // Resource:  http://localhost:8080/user/42
    // Need to use a custom regexp instead?
    // Easy,
    // just mark the parameter's type to 'string'
    // which accepts anything and make use of
    // its `regexp` macro function, i.e:
    // app.Get("/user/{id:string regexp(^[0-9]+$)}")
    app.Get("/user/{id:long}", func(ctx iris.Context) {
        userID, _ := ctx.Params().GetInt64("id")
        ctx.Writef("User ID: %d", userID)

    // Start the server using a network address.

$ go run example.go

The only requirement is the Go Programming Language

$ go get -u

Iris takes advantage of the vendor directory feature. You get truly reproducible builds, as this method guards against upstream renames and deletes.

First of all, the most correct way to begin with a web framework is to learn the basics of the programming language and the standard http capabilities, if your web application is a very simple personal project without performance and maintainability requirements you may want to proceed just with the standard packages. After that follow the guidelines:

  • Navigate through 100+1 examples and some iris starter kits we crafted for you
  • Read the godocs for any details
  • Prepare a cup of coffee or tea, whatever pleases you the most, and read some articles we found for you

Iris starter kits

  1. A basic web app built in Iris for Go
  2. A mini social-network created with the awesome Iris💖💖
  3. Iris isomorphic react/hot reloadable/redux/css-modules starter kit
  4. Demo project with react using typescript and Iris
  5. Self-hosted Localization Management Platform built with Iris and Angular
  6. Iris + Docker and Kubernetes
  7. Quickstart for Iris with Nanobox
  8. A Hasura starter project with a ready to deploy Golang hello-world web app with IRIS

Did you build something similar? Let us know!


Iris has a great collection of handlers[1][2] that you can use side by side with your web apps. However you are not limited to them - you are free to use any third-party middleware that is compatible with the net/http package, _examples/convert-handlers will show you the way.

Iris, unlike others, is 100% compatible with the standards and that's why the majority of the big companies that adapt Go to their workflow, like a very famous US Television Network, trust Iris; it's up-to-date and it will be always aligned with the std net/http package which is modernized by the Go Authors on each new release of the Go Programming Language.
