Iris Web Framework

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

It provides a beautifully expressive and easy to use foundation for your next website or API.

Simple Handler

package main

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

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

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

func main() {
  app := iris.New()
  app.Handle("PUT", "/users/{id:uint64}", updateUser)
  app.Listen(":8080")
}

func updateUser(ctx iris.Context) {
  id, _ := ctx.Params().GetUint64("id")

  var req request
  if err := ctx.ReadJSON(&req); err != nil {
    ctx.StopWithError(iris.StatusBadRequest, err)
    return
  }

  resp := response{
    ID:      id,
    Message: req.Firstname + " updated successfully",
  }
  ctx.JSON(resp)
}

MVC

package main

import (
  "github.com/kataras/iris/v12"
  "github.com/kataras/iris/v12/mvc"
)

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

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

func main() {
  app := iris.New()
  mvc.Configure(app.Party("/users"), configureMVC)
  app.Listen(":8080")
}

func configureMVC(app *mvc.Application) {
  app.Handle(new(userController))
}

type userController struct {
  // [...dependencies]
}

func (c *userController) PutBy(id uint64, req request) response {
  return response{
    ID:      id,
    Message: req.Firstname + " updated successfully",
  }
}
