In this tutorial, you will learn how to build traditional web applications and microservices in Go using the Gin framework. Gin is a framework that reduces boilerplate code that would normally go into building these applications. It also lends itself very well to creating reusable and extensible pieces of code.

this tutorial demonstrates how you can create your own simple RESTful JSON api using Go(Lang)

This tutorial introduces the basics of writing a RESTful web service API with Go and the Gin Web Framework (Gin). You'll get the most out of this tutorial if you have a basic familiarity with Go and its tooling. If this is your first exposure to Go, please see Tutorial: Get started with Go for a quick introduction.

Gin is a HTTP web framework written in Go (Golang). It features a Martini-like API with much better performance -- up to 40 times faster. If you need smashing performance, get yourself some Gin. - GitHub - gin-gonic/gin: Gin is a HTTP web framework written in Go (Golang).

Web servers are always a really cool and relatively simple project to get up and running when trying to learn a new language. In Go, this is no different, and building a web server using the net/http package is an excellent way to come to grips with some of the basics.

Go is a great language for creating simple yet efficient web servers and web services. It provides a built-in HTTP package that contains utilities for quickly creating a web or file server. The goal of this tutorial is to create a web server that can accept a GET request and serve a response.

Writing a basic HTTP server is easy using the net/http package. package main import ( "fmt" "net/http" ) A fundamental concept in net/http servers is handlers. A handler is an object implementing the http.Handler interface. A common way to write a handler is by using the http.HandlerFunc adapter on functions with the appropriate signature.

If you access the URL http://localhost:8080/world on a machine where the program below is running, you will be greeted by this page. package main import ( "fmt" "net/http" ) func main() { http.HandleFunc("/", HelloServer) http.ListenAndServe(":8080", nil) } func HelloServer(w http.ResponseWriter, r *http.Request) { fmt.Fprintf(w, "Hello, %s!", r.URL.Path[1:]) } The call to http.HandleFunc tells thenet.http package to handle all requests to the web root with theHelloServer function.

I have no clue what I'm doing wrong, I look up steps online what to do and they all tell me to just go to CMD, type in go get ___ and then just import the github link into my file but I constantly ...

This paper mainly introduces the example code of Golang to implement web file sharing service, which is shared to you as follows: It's very simple. It only takes two lines of code. Http. Handle ("/"), http. FileServer (http. Dir (". /"))// Make the current file directory a shared directory http.ListenAndServe(":8080", nil) At this point, open [...]

Welcome! Since my article talking about how to implement a Golang microservice using MVC from scratch I had a lot of questions about design patterns in Go so in this lesson I'm showing you different microservice design patterns in Golang.

Good morning, Gophers. In working with Golang, if you've ever found yourself frustrated when downloading files from the internet, saving them individually to a directory, and then opening that file in Go code, then you've come to the right place.

This article mainly introduces the Golang implementation web file sharing service sample code, to share with you, specific as follows: Very simple, just two lines of code. http.Handle("/", http.FileServer(http.Dir("./"))) // Treat the current file directory as a Shared directory http.ListenAndServe(":8080", nil) At this point, open http://ip address :8080 in your browser.

In this article I want to talk about how to structure your MVC based app so its reusable and robust. Much of the style you are going to see in this article is based on Django (Python web framework). Let's start, are we going to use a framework ?

The MVC module type integrates ASP.NET MVC 5 with the DNN platform. Note: Incompatibilities between ASP.NET MVC and ASP.NET Web Forms cause conflicts with pre-existing Web Forms features in the DNN platform. Therefore, DNN implementations of some ASP.NET features, such as MVC routing, are limited.

MVC is a well-known way to structure web applications, but it is often shunned in Go. In this article we explore how MVC can be effectively implement in Go as well as how to avoid all of the issues that many people associate with MVC.

Go offers built-in support for JSON encoding and decoding, including to and from built-in and custom data types. package main import ( "encoding/json" "fmt" "os" ) func main () { You can use tags on struct field declarations to customize the encoded JSON key names.

Package http provides HTTP client and server implementations. Get, Head, Post, and PostForm make HTTP (or HTTPS) requests: resp, err := http.Get("http://example.com/") ... resp, err := http.Post("http://example.com/upload", "image/jpeg", &buf) ... resp, err := http.PostForm("http://example.com/form", url.Values{"key": {"Value"}, "id": {"123"}}) The client must close the response body when finished with it: resp, err := http.Get("http://example.com/") if err != nil { // handle error } defer resp.Body.Close() body, err := io.ReadAll(resp.Body) // ...

I'm trying to add some values from my database to a []string in Go. Some of these are timestamps. I get the error: cannot use U.Created_date (type time.Time) as type string in array element Can I convert time.Time to string?

I am trying to restore the context with it's data after performing validation on it's data.I need the data to keep moving as need it later on in the next function. I am new to golang and the below ...

Go provides built-in support for base64 encoding/decoding. package main This syntax imports the encoding/base64 package with the b64 name instead of the default base64. It'll save us some space below. import ( b64 "encoding/base64" "fmt" ) func main () { Here's the string we'll encode/decode. data := "abc123!?$*&()'-=@~" Go supports both standard and URL-compatible base64.

Add a docker-compose.yml file on your root directory: And run it by using this command: docker-compose up -d Don't forget to add the .env in the root directory for database configuration, example below: We will write our JWT & user service on service directory.Jwt will have JwtGenerate and JwtValidate .User will have UserCreate , UserGetByID, and UserGetByEmail Auth will have UserRegister and UserLogin .

init() wil be triggered before the main() function, and follow this order of execution: init() will run only once. init() will run after global variable initialization of each package and before main() function. init() will only run if the package is imported.

When I first started writing Golang applications in 2014, I ran head first into the quirkier, more interesting parts of the language - concurrency and channels. After many lines of buggy, hard-to-reason-about code, I learned some patterns that leverage the benefits of concurrency while greatly improving code readability and reducing errors.

Make sure to tidy up your belonging and stop your activity when arrived at the destination before you leaving the train. Or else, you will lose your favorite toy (except if you all sleeping during the trip). We should do the same thing when stopping the application.

Golang is an open-source programming language made by a team at Google. It is one of the fastest-growing languages in terms of popularity, so now is an excellent time to learn its basic concepts. Go is a great choice since it was created by some of the same people who created C, Unix, and UTF-8 - three of the most influential contributions to computer science.

There is a myth that API's written in golang cannot be simple and idiomatic, like in other languages. Actually, I've come across a lot of REST API codebases that turned into a complicated mess with so many abstractions with ended up hurting both readability and maintainability.

Now the title is OK, request for comments only about the content of this post. We known the tools we're using daily like bundler(webpack), code-formatter become obstacle to our work since they are too slow to match our now days productivity.

Microservices have become a very popular approach to build software in recent years. Microservices are used to build scalable and flexible software. However, randomly building microservices across many teams can cause a big frustration and complexity. It wasn't long ago that I hadn't heard about Domain-Driven Design - DDD, but now it seems everyone is talking about it, everywhere I virtually go.

Hello there 😀 In this brief article I will explain how I write a REST API using Golang trying to follow some best practices. The source code to follow along if needed is here. As an example we'll be creating a very simple Post API.

Watermill is a Golang library for working efficiently with message streams. It is intended for building event-driven applications. It can be used for event sourcing, RPC over messages, sagas, and whatever else comes to your mind. You can use conventional pub/sub implementations like Kafka or RabbitMQ, but also HTTP or MySQL binlog, if that fits your use case.

Have you ever written an event-driven application and found out that some native libraries are kinda complex to use? I'll introduce you to a Golang library called Watermill for working efficiently with message streams and building event-driven applications. Here are some advantages of using Watermill: Simple.

A few months ago, a really nice Go package vektah/gqlgen for GraphQL became popular. This article describes how GraphQL is implemented in "Spidey", an exemplary microservices based online store. Some parts listed below are missing, but complete source code is available on GitHub. Spidey encompasses three services that are exposed to the user through a GraphQL gateway.

This tutorial will take you through the process of building a GraphQL server with gqlgen that can: Return a list of todos Create new todos Mark off todos as they are completed You can find the finished code for this tutorial here Create a directory for your project, and initialise it as a Go Module: $ mkdir gqlgen-todos $ cd gqlgen-todos $ go mod init github.com/[username]/gqlgen-todos $ go get github.com/99designs/gqlgen $ go run github.com/99designs/gqlgen init This will create our suggested package layout.

hey I was getting the same problem I figured it out how it can be done. I have two way of writing the code choose as per your choice.

At 99designs we've been on a journey to deconstruct our PHP monolith into a microservice architecture, with most new services being written in Go. During this period, our front-end team also adopted type safety, transitioning from Javascript to TypeScript & React.

GraphQL has been around for about 4 years and yet I still don't know what it does despite I read the entire product tagline from the website (yes, I'm joking). The website defines GraphQL as: GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data.
