Golang might be a relatively young programming language, however it is gaining significant exposure due to the number of things we can create with it. In this tutorial blog, we will focus on creating Ethereum DApp for block chain.

? Well, in short, Go is optimized for distributed services, handling large scalable servers and multi-core CPU architecture. This allows developers to create several goroutines without any hindrance.

So, without further ado, we will focus on the connection of Golang to an Ethereum client.


How to Establish a Connection to Ethereum Using Golang?

Golang is well-known for its CSP concurrency paradigm and robust libraries. In addition to this, there is also an Ethereum client that is implemented using Golang. You will find it by the name of geth. If you wish to know more about Go Ethereum, you should visit the link 

In this section, we will use Go to make a connection to the Ethereum client. In this regard, we will be using Infura. It is a service that is provided to the developers by consensus that allows you to connect to the Ethereum node. You can also connect to test nets as well.

Now, I’ll create a new directory in order to start the project. I usually save all my projects in go-workspace. Since I’m on a Windows system, I’ll be using the Command Prompt. In case you are using a Mac or Linux, then you have to use Terminal.

The last statement leads to the launching of VS Code. Yes, this is the IDE that I’m using for my project. You might use any other IDEs like GoLand, Zeus IDE, Vim-go, etc.

Meanwhile, if you are facing issues creating a ledger, NFT marketplace, tokens, then you should not lose hope. All you have to do is get in touch with the developers associated with Golang.company and you will get the much required assistance with 

The entire program is available on Github. All you have to do is click on the link: 

In this section, we will get started with the programming. In the VS Code, under the directory ethDApp, we will create a Go source file titled ‘main.go’. This will be the entry point to the Go application that will get connected to the Ethereum node.

The first thing that we are doing is define that this is the main package. The second thing that we will do is import a bunch of libraries. These are “context”, “fmt” for outputting, “log”. Next, we will import the Go Ethereum client from Github: github.com/ethereum/go-ethereum/common and github.com/ethereum/go-ethereum/ethclient.

Before we go on to code further, we have to trigger the go mod init in order to initialize the project. So, we will type in the Terminal:

go mod init github.com/golang-company/ethDApp


This will lead to the creation of the go.mod file.

Next, what we will have to do is get or install the packages and dependencies: github.com/ethereum/go-ethereum/common and github.com/ethereum/go-ethereum/ethclient. 

For that, we will again type in the Terminal:

go get github.com/ethereum/go-ethereum/common

go get github.com/ethereum/go-ethereum/ethclient

You will see that this leads to the creation of the go.sum file that keeps a log of all the dependencies installed.

Then we will go to the main function which will act as the entry point to the program. The first thing that you have to do is connect to the ethereum node. So, we will say here ethclient.Dial and we will pass an endpoint that will lead to an ethereum node. In this regard, we will use the Infura node.

We will use the MAINNET for this instance and we will copy the endpoint. And we will paste the endpoint after ethclient.Dial.

https://mainnet.infura.io/v3/03bf216d226d47adb501d642f9dc0c12

Next, we will store the return value of the Dial function. It has two possible values. One is the connection itself and the second one is the error that it may encounter. So, the above statement becomes

In Go, the error handling is a bit different than the rest of the programming languages. We have to check for the err variable stated and whether it has anything in it.

log.Fatal (“Failed to make a connection to the Ethereum Node”, err)

So, if the error is not nil, we will just print that it failed to connect and we can pass the err itself to the log statement.

In order to use concurrency within Go, we first have to create a context ‘context’. With the ‘context’ created, we will try to get a transaction from the Ethereum node. This will help in setting up a communication between Ethereum node and the application. To do so, we will write the following statements:


txn, pending, _ := connection.TransactionByHash (context, common.HexToHash (“0xbca59819540b55e32a9a422e44559df023c2951b97b50815fa029b67ffe2a4a7”)

In the second statement, the first parameter that we pass is the context, the second parameter we pass is the actual transaction hash we wish to look up. Now, we have to convert the transaction hash from hex to hash and we are able to do so using the common library. We say common.HexToHash.

In order to do so, I’m using Etherscan and visit a random transaction and copy the transaction hash and paste it in the statement.

We have a couple of things returned. These are the txn, pending flag (which is a boolean flag). If the pending flag is true, this means that the transaction is pending and if it’s false, it means that it’s not pending. For this, we will apply the if-else statement.

If it is pending, then we will print out a statement along with the txn. In case the condition is not met, then we print out that the Transaction is not pending along with txn.


Now, if you want to see the output, you will get to see:


Hopefully, you were able to understand the concept clearly. This is how you establish a connection with Ethereum using the programming language of Go. The process is quite simple if you understand the logic behind every step. And if you want to have a firm grasp of the concept, then you should focus on the coding. With more practice, you will definitely gain proficiency.

Ethereum DApp with Golang: Establishing Connection to Ethereum 

This blog will teach you how to create an API in Golang (Go). Moving ahead, you will understand the basic concept of API, and how you can create it in Golang. Before proceeding, you should have the postman application installed and an account created in it since at the end of the project you need to check whether your API is functioning properly or not. I will create three functions in my code to initialize the program i.e., “Create User”, “Get User” and “Delete User”. After writing down the code I will also explain how to check whether your program is initialized correctly. I have mentioned the prerequisites below,

Download the Postman Application to check your program initialization.

MongoDB Atlas (with an active user account)

For this project, I will use Gin Web Framework. Several web frameworks can be imported to perform API creation. For Example

Here, net/http is the default package through which we can initialize our program. Net/http provides HTTP client and server implementations. Other than net/http, Gorilla Mux and Gin are the two frameworks that you can use to create an API in Golang. Here, I am using the Gin Framework since it is fast, the codes are short, and more than that I feel comfortable with this framework.

As known, API stands for Application Programming Interface. Here, API is a method through which the front end or the client communicates with the backend server, and it's a one-way conversation. This conversation follows some protocols or methods known as HTTP Methods or Protocols.

If there's two-way traffic/conversation then it is known as Web Socket. This topic is not useful in our project, therefore we will discuss this in some other blog. For now, There are four types of HTTP Methods i.e., "

Before proceeding you need to understand what packages you need to import. Therefore let's list the packages that are required for our project. Below are the package links,

“go.mongodb.org/mongo-driver/bson/primitive”

“go.mongodb.org/mongo-driver/options”

There are other packages as well that you need to execute your program which I will discuss later in this blog.

To begin with we need to create the directory for our project therefore we will input some commands in the command prompt (windows) that will create a directory for your project.

 the IDE will pop up on your screen. For this blog, I am using VS Code Editor as I have mentioned above. After the creation of your workspace, you need to install the go mod file through your VS Code Terminal. for which the command is 

“go mod init github.com/(Your Github Username)/(Directory Name)”

 in my case, it is “go mod init github.com/golangcompany/RestfulAPI”. Then following this you need to input 

. After all the basic imports, you need to import the packages that I have discussed above i.e, Gin Framework and Mongo Driver by giving the command 

In this section, I will begin with my explanation of the code on IDE i.e., on VS Code Editor. Here you need to begin by creating three folders i.e., controllers, database, and models.

In controllers basically, you will define your 3 functions for CreateUser, GetUser, and Delete User. The database will store the string for the database in which you want to push your data and handle the database functions. For this tutorial, I have already mentioned that it is going to be MongoDB. The final folder i.e., models will carry out the struct “User”. Apart from these folders, we will begin with the “main.go” file which will be placed in your main directory.

You need to begin with “package main” and import the packages mentioned in the image above.

Here you will define the func main and mention the port for the establishment of the connection with the server. To understand further you need to get an idea of what a router is in Golang and what is the use case of a router.

Here in func main, you have to get the env method to fetch a port that is available in the dev system. Following that, I have also mentioned that if the program is unable to fetch any port then it will use 8080 as its port to establish the connection to the server.

In my code, I have used gin as the HTTP Web Framework. Here we are defining gin.New()as a variable router and asking it to use 

In simple words, a router is present in the application and whenever a request is sent or asked to fetch from the front end, it connects with the router and then the router delivers back or returns the data. The process itself is known as routing. As you can see in the above code, I have created 3 routes i.e., POST, GET, and DELETE.

Now, let's see how you can create a Struct.

Struct, also known as the structure, is the main field where different fields are stored in a single place. To make it more simple, let me give you an example.

Suppose you have a travel agency that offers rental cars to tourists with a chauffeur, so you will need different fields like vehicle registration number, vehicle model, seating capacity, vehicle chauffeur name, vehicle legal documents, etc, for your database, therefore, you can prepare a struct for it. In Golang, these are crucial integrations for simplifying the task of both the developer and the organization. Other languages have a different approach to these kinds of proceedings.

Grasping a concept in programming gets difficult without a sample code. Right? So, let’s understand the concept of building a Struct with a sample code syntax, given below.

This will make you learn about its convenience and capacity.

You can notice that I have entered different fields in a single place. This becomes convenient from a developer's perspective.

Hope this was helpful! Now, let us move toward our current project again.

I have not created a lengthy struct, In my code, I have included only four fields i.e., ID, Name, Gender, and Age. First, have a look at my struct before proceeding further.


Here, I will begin by writing package models and importing “go.mongo.org/mongo-driver/bson/primitive”. I have imported the “primitive” package since I want the id to be unique every time we post user data in our database. Next, you need to mention the fields and the data type.

Now, let us proceed toward our database.go file where we will set up our database and mention the MongoDB Clusters string.

If you don’t know about it you can visit this 

 to get an idea about how to connect your Golang App with MongoDB Atlas.

Here, in this section, you will learn about the three main functions through which the client will hit the API.

First, get used to the basic imports like context, fmt, net/http, and time. Further for program initialization, you need to add gin framework, mongo-driver, and gopackage-bson.

Now you need to focus on the three main functions of our API i.e., CreateUser, GetUser, and DeleteUser. But before that,

We will write a variable named UserCollection. It instructs the program to create a database named User2.

Then, you need to begin with the first function in controllers i.e., CreateUser.

This is a function that returns a gin handler function. This means it can be used as an HTTP handler in the Gin framework. In the next line, you will take two variables, i.e., ctx and cancel. This line creates a context with a timeout of 100 seconds. This is used to prevent the function from running forever if there's an error.

As you can see in my code, I have also mentioned primitive when a new user is created, it will always get stored in the database with a unique object ID.

Now let's proceed toward GetUser Function and DeleteUser Function,

With GetUser Function, you can fetch the user details from the database. Also with DeleteUser Function, you can command the program to delete the user details from the database.

The initial steps of the GetUser Function and the DeleteUser Function will be the same as the CreateUser function. With the DeleteUser function, you can return a gin handler function which is used as an HTTP handler in the Gin framework. I have created a context with a timeout of 100 seconds.

Following that, you need to take the variable id where the query method is implemented and if there's no id matching in the database it will show you an error. On the other hand, if it succeeds, then using the ObjectIDFromHex method the id will be converted from hex to object id. The FindOne method will find the user id in the database and decode it and if the error is nil, it will provide the user data to the client.


Here, as you can see in my code, for DeleteUser, the overall process is similar to GetUser. The difference lies in where I used the FindOne method to find the user id in our database and decoded it. Rather than using the FindOne Method, you need to use DeleteOne Method. The decode method is not necessary in this case since I don’t want to fetch the body of the data.

In this section, I will show the output through the Postman application with the help of some screenshots. First, let’s run the program with the command “go run main.go”.

Here you may encounter a dialog that may ask your permission for access. After approval the permission, you need to get on the postman application to verify whether the API is working properly.


Here in the postman application, first I will check the POST API. For this, you have to enter the address as http://localhost:8080/createuse and select ‘raw’.

Next, I entered the data that I want to post in my database and select the form as JSON and click on send which gives us the message ‘user created successfully’. This is the confirmation that our data is posted in our database.

Now let’s check our data in our MongoDB Cluster.

Create Rest API using Gin Web Framework in Golang

There is a big difference between knowing a language and becoming a developer. If you wish to become a 

, it would take time, patience and commitment from your end to be the absolute best. If you are ready to put in the effort, then this blog is for you. You will get a detailed insight into how to get started and master each concept.

So, let us begin!


Why Should You Opt for Backend Development?

In order to understand this easily, let us take the example of Netflix. When you login, you have to scroll through the various TV shows and movies. Once you select a show, you get to see the description of the show, choose to add captions, adjust volume, etc. Well, this represents the front-end of Netflix.
So what is backend development? Well, it is concerned with how Netflix operates, i.e, the process that goes on behind the scenes. You might have seen that Netflix showcases recommendations. Well, it tracks your behavior, and based on your interest, fetches data from the server.
Don’t you think that the task is intriguing and that you will be responsible for something only understood by a handful of people? If you are on the same page, then backend development is for you!
You should opt for backend development as it will help you get familiar with several programming languages. And this will give you the much-needed boost as far as your career is concerned. You can go on to become the most sought-after backend developer, carry out system programming, or even hone your skills to become a Full Stack developer (provided you learn database, networking and front-end development as well).

Does Golang Offer Good Career Opportunities?

By this time, you must have realized that this blog is about Golang. But why should you choose Golang?

Well, to start with, Golang is quite fast. It is said to be 40 times faster than Python! As you can imagine, you can accomplish a lot of tasks in a limited time. Golang’s support for CSP-style concurrency and parallelism makes it a good programming language for systems programming.

Furthermore, Golang was developed by Google to counter the problem of scalability. And the language consists of important libraries and is highly readable. So, Golang is easy to learn and is also very forgiving for beginners, if you commit mistakes.

If you look at LinkedIn, you will find 20,000+ job postings for Golang developers. And if you go by the statistics, then the average salary is around $100,000 per annum. Given below is a graph that shows the job ads that have been posted since the later half of 2020.


Sorce : Golang Job Statistics December 2021 (golangprojects.com)

As you can clearly tell, it is high time that you learn Golang as it is going to be in high demand in the coming five years. Who knows maybe you can land yourself a job in Google?

Are you still with me? Good! That means you have a penchant for coding and have an interest in learning Golang. Henceforth, I will guide you how to get started with Golang right from scratch.

What Are the Prerequisites for Learning Golang?

Coding in Golang is quite simple, but it would definitely help if you have any programming experience in C or Java. This will help you understand functions easily.

You need a tool that will help you edit the code. In this reward, you can opt for IDEs and text editors like VSCode which is free, or you can opt for paid ones like GoLand.

You will require a command terminal, like Powershell or cmd (Windows), or any terminal on Mac and Linux.
Finally, you have to install Go to get cracking!

Now, it’s very important that you learn Golang without being hasty. So, your primary task would be to learn and master all the basics.

You will get to know how to write your first code on Golang, presumably, Hello World code. Following this, you will learn about filenames, identifiers, keywords, types, operators, constants, for loops, control structures and functions.

Based on the concepts you discern, you have to implement them as well. And what better way can there be other than coding on your laptop or desktop? You can try finding LCM and GCD of two numbers, printing full pyramid using ‘*’, printing Floyd’s triangle, etc.
Remember the more you code, you will become aware of the interface of Golang and it would help you develop logic greatly!

Now that you have completed your initial training in Golang, it’s time to shift gears.

During the course of the next three months, you will learn about pointers, structures, interfaces and methods in Golang. You will get to know how to assign and initialize values to elements in the array. Although arrays are crucial, you will find that it is recommended that you use slices.

Slices offer more flexibility than arrays in Go. It offers access to various parts of arrays in sequential order. You can use index values to access arrays and slices. Soon, you will get introduced to maps, where keys are used to access unordered element groups. Once you get acquainted with maps, you will find it easier to retrieve data through keys.
This is what you will be learning in six months. It is better to take it slow, so that you do not face issues during the later course of learning Golang.

Following the six months, you will be delving deep into Golang. You will be:

Mastering Various Golang Libraries and Frameworks


Your focus should always be on various ways to make Go easier. Thus, you will be learning frameworks, databases and libraries. As far as frameworks are concerned, you should start with Revel, Gin, Beego, and Echo. Next, you have to learn the nitty-gritty of libraries such as GORM, Gen, CLI, etc.
FInally, you will move on to databases, for which you can check out PostgreSQL or Oracle.
Timeline: 2-3 months


Error handling is a bit different in Golang compared to other languages. But, if you are beginning Golang itself, then you would have to be attentive while you debug. Otherwise, errors might pass on silently and that is just asking for trouble.
If a function is destined to fail or have issues, you would get the errors in terms of final values when you call the function. You will not be shown any exceptions. Now, it is upto you to decide what you wish to do with the errors.



Code reuse is an integral part of Golang. And you have to use packages for that, namely the ‘fmt’ package. This package deals with numerous functions associated with formatting and output. Basically, it keeps the function names precise and helps in organization of codes. Once you learn about packages for reusing codes, you will get introduced to modules. It stores Golang package collection in a tree, with the go.mod file defining the path used for importing the root directory.


In Golang, you will get introduced to concurrency, from which you can decipher the meaning of sequential and concurrent execution. You will learn about Goroutines and how it is handled with timers to run program tasks and manage responses. Soon, you will get introduced to Channels which helps in easing the communication between Goroutines. Since channels are typed, you can use them as function return values, etc.



So, in a time span of 1 year, you will be learning so much. The important thing here is to keep revising and applying the concepts that you have learnt via programming.

So far so good? Great! Then let’s move on to the next chapter of your learning journey.


If you are new to testing, then it is ideal if you begin with unit testing. Although Go libraries have testing packages by default, you should use frameworks like Gingko and GoCheck for unit, behavior and integration testing.
While integration tests ensure that every component of an application functions flawlessly together, unit tests focus on testing the smallest components of a given software. Functional tests, on the other hand, check whether or not the program conforms to the requirements.

        Timeline: 6 weeks (roughly 2 months)


If you wish to establish yourself as a good Golang developer, then you would have to know about command line apps. Golang is a popular choice for Command Line Interface as it does not have deployment dependencies. It compiles to a static binary. Soon, you will learn to create subcommands and deal with arguments. And gradually, you will learn how to interact with an OS.



The graph below depicts how many programmers are willing to learn Golang.

Source: Google's Go scores as the top language developers want to learn


This is the most challenging yet interesting part of being a Golang developer. This is a never ending learning process and the more you create, the more you will learn about encoding and decoding APIs. You will get to know how to work with databases, converting data structures in GO into JSON with marshaling, building routers, describing path variables and more.
You will also need to know about handlers that are responsible for returning specific or all items, or adding new items.


Everything looks good on paper, until you try to apply it. You might be wondering how you can track your progress in Golang programming. Well, you can always take tests to check whether you have understood the concepts or not. You can try various sites like Gitbook, TestDome, Adaface, etc.

Another way to track your progress would be to debug and assess other’s codes. You can try to find faults in the codes, or you can modify the lines a bit.

Finally, you will have to work on projects, carry out system programming, build REST APIs, or develop concurrent programs.

If you see that you are able to handle all these tasks with ease, then you have become a master in Golang and are ready to work for any big company in the world as a Golang developer specializing in "

." So, you can see that all it takes is hard work and an interest in programming. Nobody has an innate sense for programming, rather it has to be developed!

How to Become a Golang Developer?

Choosing a language for server-side programming should be based on your long-term goals and the requirements of the project. So, asking should I hire a Go developer or should I opt for Rust development aimlessly won’t help you out. However, if you find yourself to be in a spot of bother, then this blog will clear the air for you. So, let us get started.

Go is a statically typed, AOT-compiled language. On the other hand, Rust is a statically, strongly typed and AOT-compiled language. Rust is a multi-paradigm, high-level and general purpose language.

Let us assess both the languages on the basis of various parameters.

Simplicity is one of the major Go selling points. Whereas a development process could take hours or days in the case of Golang, it could take upto weeks for Rust. This has a significant influence over collaborations.

Go programs are easy to decipher, easy to write and simple to manage in large teams. On the other hand, Rust is a very complex language to learn. It takes hours to become productive in Rust.

Furthermore, various useful features like generics which were at one time missing in Golang, have been incorporated in the version 1.18.

When it comes to performance, both Golang and Rust are highly sought-after. They have great internal, high-performance tools for managing dependencies and standard builds. Due to its perfectly alright control over how threads operate and how resources are shared across threads, Rust will nearly always defeat Go in run-time benchmarks.

Both the languages- Rust and Go- make use of a similar formatting tool. You have rustfmt for Rust and you have gofmt for Go. They automatically reformat your code in accordance with canonical style.

Go abstracts away from the architectural specifics to help programmers focus on the issue at hand. This is completely opposite to what we observe in Go.

While Go lacks the runtime speed in comparison to Rust, it has faster development and compilation. This is because Rust compiler performs a number of optimizations and checks. This makes Rust unsuitable for large projects.

However, in the case of deployment, both of them are the same. They produce static binary as an output. In order to run it, you won’t need an interpreter.

Meanwhile, if you are stuck with microservice development or building a server in Golang, you should 

 from Golang.Company. They will assist you with various steps and build you a scalable and robust application.

The graph below depicts the state of benchmark test between Rust and Go.

Go has great support for concurrency. Most developers admit that goroutines and channels are the best features of Golang. However, these features are also available in Rust, that are accessible via the standard library or third-party libraries like Tokio.

The Rust concurrency model is deemed to be ‘correct’. This means that the compiler is able to catch a class of thread safety bugs at the time compilation, before the execution of the program. This allows developers to avoid mistakes like writing it to the same shared variable without any synchronization.

Goroutines are basically lightweight threads. These are run-time-managed Go objects that are scheduled across OS threads. Goroutines are very easy to create and cheaply, and the stack's size can be adjusted over time. Because OS threads are far more expensive than goroutines, developers can build thousands of goroutines instead.

This solution's drawback is that it increases CPU and memory overhead in the case of Go. However, Rust has a solution for this issue as it strives to minimize even minor overheads.

Both programming languages have a similar approach to handling errors. In Golang, the functions return several values in addition to the error. The dedicated type, the enum, is introduced by Rust and has two subtypes: result type and error type.

Error handling may be made less verbose than in Golang by unwrapping it with a question mark (? ). For both the languages, the handling is detailed and cleaner.

These approaches help developers look for functions where the error is not handled properly. This makes code writing easier and safer in Rust and Go.

If you are willing to know the trend involving the interest over the languages, then you should take a look at the graph below.

In Rust, one has to perform a lot of tasks in order to ensure that the code is secure. This is because the language ensures memory safety at the time of compilation utilizing innovative ownership mechanisms. The compiler is extremely ‘stringent’ as it does not let any unsafe memory code to pass through. Rust also presents multiple concurrency models to ensure that there are no lapses in memory safety.

Go, on the other hand, is not memory safe. In Go, non-atomic multi word structs implement interfaces and slices. Furthermore, data races lead to invalid values which at times lead to memory corruption.

However, Go, like Rust, can be considered safe for handling use-after-free and dangling pointers. Go uses an automated garbage collector to limit the issues related to memory leaks. On the other hand, the ownership and borrowing functionality is a great feature of Rust. According to this principle, every item has an owner which has the option of lending it out or giving it to someone else.

Rust also allows us to build numerous immutable references or ONE AND ONLY changeable references. With this method, Rust fixes frequent memory issues without the need of a garbage collector, outperforming Golang in terms of performance.

However, there is one point that you have to keep in mind. Even though the Rust compiler is extremely efficient in catching memory bugs and helps you write very performant code, it comes at a price. This is the Peter Parker principle, which means you have to be very careful when you use Rust.

Below is a graph that depicts the memory usage between Go and Rust (and Java).

While Golang came into the scene in 2009, Rust made the entry in the year 2013. So, coupled with Golang’s simplicity, it is one of the most popular languages among developers.

Moreover, the libraries and frameworks are more mature in Go than in the case of Rust, especially the ones that are associated with web development.

However, the developers of Rust are extremely communicative and being an open-source language like Go, is subject to further developments.

Last but not the least, career opportunity is an aspect that you have to consider. If your goal is to get hired, you should look at the market that has the most jobs. One hand, if you see, you have next to no jobs in Rust. On the other hand, you have lots of jobs in Golang.

Companies that are using Golang are Google, Uber, Twitch, Dailymotion, SendGrid, Dropbox, Soundcloud, etc. On the contrary, companies that are using Rust are Brave (Github), Atlassian, Amazon, Discord, etc.

The average salary per annum of a Rust developer is around $120k per year. However, the average developer salary for Golang is around $135k per year.

If your project involves web development, distributable servers, then it is recommended that you opt for Go. The programming part is extremely easy and the concurrency model will help you out a lot. But if you are going for the development of a CLI application, then you should choose Rust because of string processing, the libraries it contains. Having said that, Rust is not one of the easiest languages to master.

Golang vs Rust- Which Language to be choose for Server-Side Programming?

Go is a statically typed, compiled programming language designed by Robert Griesemer, Rob Pike, and Ken Thompson. Usually referred to as Golang but the actual name is Go, the two reasons for the name is Go was designed at Google and secondly was because the first URL was golang.org. It is syntactically identical to C, but with the plus points of memory safety, better garbage collection, structural typing, and CSP(Communicating sequential processes) - style execution of out-of-order or in partisan order.

all are three somewhat similar commands. These three commands either work on a single Go file or a list of Go files. Usually, these commands run on command lines for macOS/Linux its terminal and for windows its command prompt.

Here is the sample file which might be helpful for you to understand the commands better.

It compiles and executes the main package which contains the .go file specified on the terminal. This command compiles the statement and stores it in a temporary file. The syntax for the command is -

If you run this in a command line you’ll get the output from the main function’s print statement but the compilation won’t be stored anywhere. As the code complies from high-level language to low language and stores in a temporary file, using 

 is useful and highly recommended when you’re learning the Go or working/testing a small programme or on the testing phase of your application and don’t want to take the storage.

For example, if you run the command using the sample -

go build scrutinizes the files in the directory to see which file (from the list) or part of the file is actually included in the main package. It is usually used to compile the packages and dependencies that are user-defined i.e. defined by you or pre-defined ones but you used in your file. When you have the binary file you made for the application or part of the bigger project to use later or it is a file that can be used in other applications or want to excess this file remotely then go build is the command for you. Using this command helps you build a different and permanent binary file in the current directory of your project/application. The syntax is -

go build only focuses on building the packages and never on the result so it does discard the result once you exit the window.

The command using the above example will look like -

go install exactly works like go build but the only difference is instead of purring the binary file/ the complied file in the current directory (or user-specified directory) it places it in the ‘$GOPATH/bin’ directory with other binary files and packages of third-party tools that you installed via 

. It builds and afterwards also installs the packages into the ‘$GOPATH/bin’ unlike go build. The syntax is similar -

The difference is that the output that you wanted to show using the print statement in your main package will be shown when you run ‘$GOPATH/bin’ in your command line.

If for trial purposes you want to use the same code as above, the go install will be written like this -

Top 6 Golang Backend Framework For Developer

GOARCH and GOOS are Go’s cross-platform build commands. If you are working and developing an application on one kind of operating system and want to transfer and compile the file to the other kind 

Below is an example of compiling a golang binary for Linux on a macOS terminal:

GOOS and GOARCH can build the source code without the help of a compiler.
