Iris vs .NET Core(C#) vs Node.js (Express)

Benchmarks from third-party source over the rest web frameworks

Comparison with other frameworks

Updated at: Tuesday, 21 November 2017

Built with ♥️

We have no doubt you will able to find other web frameworks written in Go and even put up a real fight to learn and use them for quite some time but make no mistake, sooner or later you will be using Iris, not because of the ergonomic, high-performant solution that it provides but its well-documented unique features, as these will transform you to a real rockstar geek.

No matter what you're trying to build, Iris covers every type of application, from micro services to large monolithic web applications. It's actually the best piece of software for back-end web developers you can find online.

Iris may have reached version 8, but we're not stopping there. We have many feature ideas on our board that we're anxious to add and other innovative web development solutions that we're planning to build into Iris.

Accelerated by KeyCDN, a simple, fast and reliable CDN.

We are developing this project using the best code editor for Golang; Visual Studio Code supported by Microsoft.

If you're coming from nodejs world, Iris is the expressjs equivalent for Gophers.

Installation

The only requirement is the Go Programming Language

$ go get -u github.com/kataras/iris

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

Getting Started

package main

import "github.com/kataras/iris"

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
        ctx.View("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.
    app.Run(iris.Addr(":8080"))
}

Quick MVC Tutorial

package main

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

func main() {
    app := iris.New()

    app.Controller("/helloworld", new(HelloWorldController))

    app.Run(iris.Addr("localhost:8080"))
}

type HelloWorldController struct {
    mvc.C

    // [ Your fields here ]
    // Request lifecycle data
    // Models
    // Database
    // Global properties
}

//
// GET: /helloworld

func (c *HelloWorldController) Get() string {
    return "This is my default action..."
}

//
// GET: /helloworld/{name:string}

func (c *HelloWorldController) GetBy(name string) string {
    return "Hello " + name
}

//
// GET: /helloworld/welcome

func (c *HelloWorldController) GetWelcome() (string, int) {
    return "This is the GetWelcome action func...", iris.StatusOK
}

//
// GET: /helloworld/welcome/{name:string}/{numTimes:int}

func (c *HelloWorldController) GetWelcomeBy(name string, numTimes int) {
    // Access to the low-level Context,
    // output arguments are optional of course so we don't have to use them here.
    c.Ctx.Writef("Hello %s, NumTimes is: %d", name, numTimes)
}

The _examples/mvc and mvc/controller_test.go files explain each feature with simple paradigms, they show how you can take advandage of the Iris MVC Binder, Iris MVC Models and many more...

Every exported func prefixed with an HTTP Method(Get, Post, Put, Delete...) in a controller is callable as an HTTP endpoint. In the sample above, all funcs writes a string to the response. Note the comments preceding each method.

An HTTP endpoint is a targetable URL in the web application, such as http://localhost:8080/helloworld, and combines the protocol used: HTTP, the network location of the web server (including the TCP port): localhost:8080 and the target URI /helloworld.

The first comment states this is an HTTP GET method that is invoked by appending "/helloworld" to the base URL. The third comment specifies an HTTP GET method that is invoked by appending "/helloworld/welcome" to the URL.

Controller knows how to handle the "name" on GetBy or the "name" and "numTimes" at GetWelcomeBy, because of the By keyword, and builds the dynamic route without boilerplate; the third comment specifies an HTTP GET dynamic method that is invoked by any URL that starts with "/helloworld/welcome" and followed by two more path parts, the first one can accept any value and the second can accept only numbers, i,e: "http://localhost:8080/helloworld/welcome/golang/32719", otherwise a 404 Not Found HTTP Error will be sent to the client instead.

Quick MVC Tutorial #2

Iris has a very powerful and blazing fast MVC support, you can return any value of any type from a method function and it will be sent to the client as expected.

  • if string then it's the body.
  • if string is the second output argument then it's the content type.
  • if int then it's the status code.
  • if error and not nil then (any type) response will be omitted and error's text with a 400 bad request will be rendered instead.
  • if (int, error) and error is not nil then the response result will be the error's text with the status code as int.
  • if bool is false then it throws 404 not found http error by skipping everything else.
  • if custom struct or interface{} or slice or map then it will be rendered as json, unless a string content type is following.
  • if mvc.Result then it executes its Dispatch function, so good design patters can be used to split the model's logic where needed.

The example below is not intended to be used in production but it's a good showcase of some of the return types we saw before;

package main

import (
    "github.com/kataras/iris"
    "github.com/kataras/iris/middleware/basicauth"
    "github.com/kataras/iris/mvc"
)

// Movie is our sample data structure.
type Movie struct {
    Name   string `json:"name"`
    Year   int    `json:"year"`
    Genre  string `json:"genre"`
    Poster string `json:"poster"`
}

// movies contains our imaginary data source.
var movies = []Movie{
    {
        Name:   "Casablanca",
        Year:   1942,
        Genre:  "Romance",

var basicAuth = basicauth.New(basicauth.Config{
    Users: map[string]string{
        "admin": "password",
    },
})


func main() {
    app := iris.New()

    app.Use(basicAuth)

    app.Controller("/movies", new(MoviesController))

    app.Run(iris.Addr(":8080"))
}

// MoviesController is our /movies controller.

func (c *MoviesController) PutBy(id int) Movie {
    // get the movie
    m := movies[id]

    // get the request data for poster and genre
    file, info, err := c.Ctx.FormFile("poster")
    if err != nil {
        c.Ctx.StatusCode(iris.StatusInternalServerError)
        return Movie{}
    }
    file.Close()            // we don't need the file
    poster := info.Filename // imagine that as the url of the uploaded file...
    genre := c.Ctx.FormValue("genre")

    // update the poster
    m.Poster = poster
    m.Genre = genre
    movies[id] = m

    return m
}

// DeleteBy deletes a movie
// Demo:
// curl -i -X DELETE -u admin:password http://localhost:8080/movies/1
func (c *MoviesController) DeleteBy(id int) iris.Map {
    // delete the entry from the movies slice
    deleted := movies[id].Name
    movies = append(movies[:id], movies[id+1:]...)
    // and return the deleted movie's name
    return iris.Map{"deleted": deleted}
}

Quick MVC Tutorial #3

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 one typical example below;

folder structure example

Shhh, let's spread the code itself.

Data Model Layer

// file: datamodels/movie.go

package datamodels

// Movie is our sample data structure.
// Keep note that the tags for public-use (for our web app)
// should be kept in other file like "web/viewmodels/movie.go"
// which could wrap by embedding the datamodels.Movie or
// declare new fields instead butwe will use this datamodel
// as the only one Movie model in our application,
// for the shake of simplicty.
type Movie struct {
    ID     int64  `json:"id"`
    Name   string `json:"name"`
    Year   int    `json:"year"`
    Genre  string `json:"genre"`
    Poster string `json:"poster"`
}

Data Source / Data Store Layer

// file: datasource/movies.go

package datasource

import "github.com/kataras/iris/_examples/mvc/overview/datamodels"

// Movies is our imaginary data source.
var Movies = map[int64]datamodels.Movie{
    1: {
        ID:     1,
        Name:   "Casablanca",
        Year:   1942,
        Genre:  "Romance",
        Poster: "https://iris-go.com/images/examples/mvc-movies/1.jpg",
    },
    2: {
        ID:     2,
        Name:   "Gone with the Wind",
        Year:   1939,
        Genre:  "Romance",
        Poster: "https://iris-go.com/images/examples/mvc-movies/2.jpg",
    },
    3: {
        ID:     3,
        Name:   "Citizen Kane",
        Year:   1941,
        Genre:  "Mystery",
        Poster: "https://iris-go.com/images/examples/mvc-movies/3.jpg",
    },
    4: {
        ID:     4,
        Name:   "The Wizard of Oz",
        Year:   1939,
        Genre:  "Fantasy",
        Poster: "https://iris-go.com/images/examples/mvc-movies/4.jpg",
    },
    5: {
        ID:     5,
        Name:   "North by Northwest",
        Year:   1959,
        Genre:  "Thriller",
        Poster: "https://iris-go.com/images/examples/mvc-movies/5.jpg",
    },
}

Repositories

The layer which has direct access to the "datasource" and can manipulate data directly.

// file: repositories/movie_repository.go

package repositories

import (
    "errors"
    "sync"

    "github.com/kataras/iris/_examples/mvc/overview/datamodels"
)

// Query represents the visitor and action queries.
type Query func(datamodels.Movie) bool

// MovieRepository handles the basic operations of a movie entity/model.
// It's an interface in order to be testable, i.e a memory movie repository or
// a connected to an sql database.
type MovieRepository interface {
    Exec(query Query, action Query, limit int, mode int) (ok bool)

    Select(query Query) (movie datamodels.Movie, found bool)
    SelectMany(query Query, limit int) (results []datamodels.Movie)

    InsertOrUpdate(movie datamodels.Movie) (updatedMovie datamodels.Movie, err error)
    Delete(query Query, limit int) (deleted bool)
}

// NewMovieRepository returns a new movie memory-based repository,
// the one and only repository type in our example.
func NewMovieRepository(source map[int64]datamodels.Movie) MovieRepository {
    return &movieMemoryRepository{source: source}
}

// movieMemoryRepository is a "MovieRepository"
// which manages the movies using the memory data source (map).
type movieMemoryRepository struct {
    source map[int64]datamodels.Movie
    mu     sync.RWMutex
}

const (
    // ReadOnlyMode will RLock(read) the data .
    ReadOnlyMode = iota
    // ReadWriteMode will Lock(read/write) the data.
    ReadWriteMode
)

func (r *movieMemoryRepository) Exec(query Query, action Query, actionLimit int, mode int) (ok bool) {
    loops := 0

    if mode == ReadOnlyMode {
        r.mu.RLock()
        defer r.mu.RUnlock()
    } else {
        r.mu.Lock()
        defer r.mu.Unlock()
    }

    for _, movie := range r.source {
        ok = query(movie)
        if ok {
            if action(movie) {
                loops++
                if actionLimit >= loops {
                    break // break
                }
            }
        }
    }

    return
}

// Select receives a query function
// which is fired for every single movie model inside
// our imaginary data source.
// When that function returns true then it stops the iteration.
//
// It returns the query's return last known "found" value
// and the last known movie model
// to help callers to reduce the LOC.
//
// It's actually a simple but very clever prototype function
// I'm using everywhere since I firstly think of it,
// hope you'll find it very useful as well.
func (r *movieMemoryRepository) Select(query Query) (movie datamodels.Movie, found bool) {
    found = r.Exec(query, func(m datamodels.Movie) bool {
        movie = m
        return true
    }, 1, ReadOnlyMode)

    // set an empty datamodels.Movie if not found at all.
    if !found {
        movie = datamodels.Movie{}
    }

    return
}

// SelectMany same as Select but returns one or more datamodels.Movie as a slice.
// If limit <=0 then it returns everything.
func (r *movieMemoryRepository) SelectMany(query Query, limit int) (results []datamodels.Movie) {
    r.Exec(query, func(m datamodels.Movie) bool {
        results = append(results, m)
        return true
    }, limit, ReadOnlyMode)

    return
}

// InsertOrUpdate adds or updates a movie to the (memory) storage.
//
// Returns the new movie and an error if any.
func (r *movieMemoryRepository) InsertOrUpdate(movie datamodels.Movie) (datamodels.Movie, error) {
    id := movie.ID

    if id == 0 { // Create new action
        var lastID int64
        // find the biggest ID in order to not have duplications
        // in productions apps you can use a third-party
        // library to generate a UUID as string.
        r.mu.RLock()
        for _, item := range r.source {
            if item.ID > lastID {
                lastID = item.ID
            }
        }
        r.mu.RUnlock()

        id = lastID + 1
        movie.ID = id

        // map-specific thing
        r.mu.Lock()
        r.source[id] = movie
        r.mu.Unlock()

        return movie, nil
    }

    // Update action based on the movie.ID,
    // here we will allow updating the poster and genre if not empty.
    // Alternatively we could do pure replace instead:
    // r.source[id] = movie
    // and comment the code below;
    current, exists := r.Select(func(m datamodels.Movie) bool {
        return m.ID == id
    })

    if !exists { // ID is not a real one, return an error.
        return datamodels.Movie{}, errors.New("failed to update a nonexistent movie")
    }

    // or comment these and r.source[id] = m for pure replace
    if movie.Poster != "" {
        current.Poster = movie.Poster
    }

    if movie.Genre != "" {
        current.Genre = movie.Genre
    }

    // map-specific thing
    r.mu.Lock()
    r.source[id] = current
    r.mu.Unlock()

    return movie, nil
}

func (r *movieMemoryRepository) Delete(query Query, limit int) bool {
    return r.Exec(query, func(m datamodels.Movie) bool {
        delete(r.source, m.ID)
        return true
    }, limit, ReadWriteMode)
}

Services

The layer which has access to call functions from the "repositories" and "models" (or even "datamodels" if simple application). It should contain the most of the domain logic.

// file: services/movie_service.go

package services

import (
    "github.com/kataras/iris/_examples/mvc/overview/datamodels"
    "github.com/kataras/iris/_examples/mvc/overview/repositories"
)

// MovieService handles some of the CRUID operations of the movie datamodel.
// It depends on a movie repository for its actions.
// It's here to decouple the data source from the higher level compoments.
// As a result a different repository type can be used with the same logic without any aditional changes.
// It's an interface and it's used as interface everywhere
// because we may need to change or try an experimental different domain logic at the future.
type MovieService interface {
    GetAll() []datamodels.Movie
    GetByID(id int64) (datamodels.Movie, bool)
    DeleteByID(id int64) bool
    UpdatePosterAndGenreByID(id int64, poster string, genre string) (datamodels.Movie, error)
}

// NewMovieService returns the default movie service.
func NewMovieService(repo repositories.MovieRepository) MovieService {
    return &movieService{
        repo: repo,
    }
}

type movieService struct {
    repo repositories.MovieRepository
}

// GetAll returns all movies.
func (s *movieService) GetAll() []datamodels.Movie {
    return s.repo.SelectMany(func(_ datamodels.Movie) bool {
        return true
    }, -1)
}

// GetByID returns a movie based on its id.
func (s *movieService) GetByID(id int64) (datamodels.Movie, bool) {
    return s.repo.Select(func(m datamodels.Movie) bool {
        return m.ID == id
    })
}

// UpdatePosterAndGenreByID updates a movie's poster and genre.
func (s *movieService) UpdatePosterAndGenreByID(id int64, poster string, genre string) (datamodels.Movie, error) {
    // update the movie and return it.
    return s.repo.InsertOrUpdate(datamodels.Movie{
        ID:     id,
        Poster: poster,
        Genre:  genre,
    })
}

// DeleteByID deletes a movie by its id.
//
// Returns true if deleted otherwise false.
func (s *movieService) DeleteByID(id int64) bool {
    return s.repo.Delete(func(m datamodels.Movie) bool {
        return m.ID == id
    }, 1)
}

View Models

There should be the view models, the structure that the client will be able to see.

Example:

import (
    "github.com/kataras/iris/_examples/mvc/overview/datamodels"

    "github.com/kataras/iris/context"
)

type Movie struct {
    datamodels.Movie
}

func (m Movie) IsValid() bool {
    /* do some checks and return true if it's valid... */
    return m.ID > 0
}

Iris is able to convert any custom data Structure into an HTTP Response Dispatcher, so theoretically, something like the following is permitted if it's really necessary;

// Dispatch completes the `kataras/iris/mvc#Result` interface.
// Sends a `Movie` as a controlled http response.
// If its ID is zero or less then it returns a 404 not found error
// else it returns its json representation,
// (just like the controller's functions do for custom types by default).
//
// Don't overdo it, the application's logic should not be here.
// It's just one more step of validation before the response,
// simple checks can be added here.
//
// It's just a showcase,
// imagine the potentials this feature gives when designing a bigger application.
//
// This is called where the return value from a controller's method functions
// is type of `Movie`.
// For example the `controllers/movie_controller.go#GetBy`.
func (m Movie) Dispatch(ctx context.Context) {
    if !m.IsValid() {
        ctx.NotFound()
        return
    }
    ctx.JSON(m, context.JSON{Indent: " "})
}

However, we will use the "datamodels" as the only one models package because Movie structure doesn't contain any sensitive data, clients are able to see all of its fields and we don't need any extra functionality or validation inside it.

Controllers

Handles web requests, bridge between the services and the client.

// file: web/controllers/movie_controller.go

package controllers

import (
    "errors"

    "github.com/kataras/iris/_examples/mvc/overview/datamodels"
    "github.com/kataras/iris/_examples/mvc/overview/services"

    "github.com/kataras/iris"
    "github.com/kataras/iris/mvc"
)

// MovieController is our /movies controller.
type MovieController struct {
    mvc.C

    // Our MovieService, it's an interface which
    // is binded from the main application.
    Service services.MovieService
}

// Get returns list of the movies.
// Demo:
// curl -i http://localhost:8080/movies
//
// The correct way if you have sensitive data:
// func (c *MovieController) Get() (results []viewmodels.Movie) {
//  data := c.Service.GetAll()
//
//  for _, movie := range data {
// 	  results = append(results, viewmodels.Movie{movie})
//  }
//  return
// }
// otherwise just return the datamodels.
func (c *MovieController) Get() (results []datamodels.Movie) {
    return c.Service.GetAll()
}

// GetBy returns a movie.
// Demo:
// curl -i http://localhost:8080/movies/1
func (c *MovieController) GetBy(id int64) (movie datamodels.Movie, found bool) {
    return c.Service.GetByID(id) // it will throw 404 if not found.
}
