When it comes to expressive web-apps in golang particularly with that django style, nothing can surpass beego the expressive & progressive web framework for golang. Now I've already talked about Fiber previously & no doubt fiber is spectacular when lightweight frameworks are being talked about. Beego is infinitely scalable if you ask me.

Let's make an App

You'll have to install beego with

go get

The $GOPATH/bin must be in your $PATH variable, so that the bee cli can work.

Start by creating a new project.

bee new test

here's the file structure.

├── conf
│   └── app.conf
├── controllers
│   └── default.go
├── main.go
├── models
├── routers
│   └── router.go
├── static
│   ├── css
│   ├── img
│   └── js
├── tests
│   └── default_test.go
└── views
    └── index.tpl

As you can see, it's already pretty expressive.

You can easily run a bee app using

bee run #inside the root directory ( i.e., test here )

Session Caching

Session caching is easy as 1, 2, 3 with beego.

import (
var globalSessions *session.Manager
func init() {
    globalSessions, _ = session.NewManager("memory", `{"cookieName":"gosessionid", "enableSetCookie,omitempty": true, "gclifetime":3600, "maxLifetime": 3600, "secure": false, "sessionIDHashFunc": "sha1", "sessionIDHashKey": "", "cookieLifeTime": 3600, "providerConfig": ""}`)
    go globalSessions.GC()

With this you can easily use sessions in your web-app.

func login(w http.ResponseWriter, r *http.Request) {
    sess, _ := globalSessions.SessionStart(w, r)
    defer sess.SessionRelease(w)
    username := sess.Get("username")
    if r.Method == "GET" {
        t, _ := template.ParseFiles("login.gtpl")
        t.Execute(w, nil)
    } else {
        sess.Set("username", r.Form["username"])

Scaling session caching#

Good question. You want to scale session caching from a memory db to a persistent database. Well that's pretty much a piece of cake with beego. Check out all about it here


So this is one of the more highlighted features of beego, providing an i18n module. This actually helps making internationalized web apps easily.

Install the package using

go get

The format of locale files is very much like the INI format configuration file, which is basically key-value pairs. But this module has some improvements. Every language corresponds to a locale file, for example, under conf directory, there are two files called locale_en-US.ini and locale_zh-CN.ini.

You can now, easily register locale files into your app

langs := strings.Split(beego.AppConfig.String("lang::types"), "|")
names := strings.Split(beego.AppConfig.String("lang::names"), "|")
langTypes = make([]*langType, 0, len(langs))
for i, v := range langs {
    langTypes = append(langTypes, &langType{
        Lang: v,
        Name: names[i],

for _, lang := range langs {
    beego.Trace("Loading language: " + lang)
    if err := i18n.SetMessage(lang, "conf/"+"locale_"+lang+".ini"); err != nil {
        beego.Error("Fail to set message file: " + err.Error())

You can easily set cookies, based on the locale chosen and then use it.

I would love to go about specifying how to internationalize your web app, in another blog!


Yes, beego has it's own drivers for a variety of different databases, making it fast and efficient while developing incredible web applications. I won't go about it this blog, but i'll surely make another blog specifically on the following topic. You can check about the orm here in the meantime.

Important features of beego

Beego is similar to the Django website framework for Python. It offers a plethora of features that are common to the web application.

Apart from the general MVC elements, it moreover incorporates an ORM (Object-Relationship Map) to access session handling tools, data, an in-built cache handler, logging systems, and libraries for general operations with HTTP components.

Beego is familiar to Django in terms of CL (Command Line) Tools. A programmer can use bee command for developing Beego apps from the beginning or deal with the existing ones. Beego,

  • Saves a lot of time
  • Faster web app development
  • Integrates ORM, built-in cache handler
  • No need for third party library

Hope you've understood how beego works, and why it's a good option if you're making an industry standard web application. Till next time! 🦄
