海外TECH	DEV Community	Getting Started in Go	https://dev.to/jeffotoni/getting-started-in-go-599d	Getting Started in GoPurpose of this post is simply to present a little of why the language Go appeared and present a little of its syntax and demonstrate some areas where Go is more applied For everyone who would like to further increase their arsenal for web development this post will help you to clarify some important points when we are starting and learning a new programming language Getting Started in Go️Before we start it s important to point out that programming languages ​​are tools and like any good tool we have to know when to use them There are scenarios and problems that are only solved with specific languages ​​and there are other universes of problems that we have hundreds or thousands of languages ​​that somehow solve the same problem So like a good professional the more tools you know to solve problems the better it will be for your professional career The Go language in its universe of possibilities is a common use language I don t really like this term it seems like it s like a silver bullet and solves all problems but not really Go was born by a purpose and solve problems of the web universe and take advantage of the new technology of multicores in servers well this was the initial purpose History of the Go project“Robert Griesemer Rob Pike and Ken Thompson began sketching goals for a new language on the whiteboard on September Within days the goals settled into a plan to do something and a fair idea of ​​what it would be like Design continued part time in parallel with unrelated work In January Ken started work on a compiler to explore ideas it generated C code as its output By mid year the language had become a full time project and had established itself enough to try a production compiler In May Ian Taylor started independently on a GCC frontend for Go using the preliminary specs Russ Cox joined in late and helped move the language and libraries from prototype to reality Go became a public open source project on November Countless people from the community contributed ideas discussions and code “There are now millions of Go programmers “Gophers around the world and there are more every day The success of Go far exceeded expectations Why they created a new language“Go was born out of frustration with the existing languages ​​and environments for the work we were doing at Google Programming had become too difficult and the choice of languages ​​was partly to blame You had to choose between efficient compilation efficient execution or ease of programming all three were not available in the same primary language Programmers who might choose ease over security and efficiency switching to dynamically typed languages ​​like Python and JavaScript rather than C or to a lesser extent Java “Go addressed these issues by trying to combine the programming ease of an interpreted dynamic language with the efficiency and security of a statically compiled language It was also intended to be modern with support for networked and multicore computing Finally working with Go is intended to be fast it should take a few seconds at most to build a large executable on a single computer A new Go language is born to meet new needs and solve problems by taking advantage of the computational power as much as possible And of course creating your mascot for the thousands of gophers that saw to emerge from this moment on Official siteTo start in Go️let s take a few steps back let s start our whole trajectory knowing the official website of lang this is the official page golang org here we will find all the information we could know about Go and much more Here we have the docs packages blog and our darling play golang org language specs download Go tour and much more The official website apparently looks small but it is very complete and big So we have practically everything we need to know about Go to start our learning in this language that is a phenomenon Where do I start on the SiteI m going to create a line of reasoning so that we can understand Go in the most practical way possible Before installing Go or running Go through play let s go through some parts of the doc so that we can understand a little of the history of Go and why a new language was born in this universe of thousands of programming languages Effective GoThis link is the first one that everyone should read first Effective Go️on this site you will find all the material you need to get a good idea of ​​the Go language Control Structure Functions Concurrent Programming using Goroutines Methods Maps and much more A go tourThis link would be the second most important link in my hierarchy for us to learn Go Tour Go️on this site you will be able to test and take a look at some of the features of the Go language that s right all through the browser without having to install anything on the machine Playground GoHere is very beautiful you don t need to install anything on the machine to run something quickly in Go just enter play golang orgPlay Go️on this site you will be able to run Go that s right we don t need to install anything for now you can run everything through the browser and get to know the syntax of the language and learning Frequently Asked QuestionsThis link would be our third step I believe you now have several questions generated by Effective Go and by Tour that did Faq️this is where you will take a few hours to read this it doesn t have to be all at once of course but you must read it This page is essential to organize your ideas and really understand a little more about Go This is one of the largest pages and requires more reading but this page is essential for a better understanding of the Go language the time you spend reading this page will surely save you hours of work Native Go packagesThis link would be so you can take a look and understand how they are organized and how is the documentation of the functions libs pkgs that we can use in the Go language This is one of the strengths of the language it is very complete for web development for servers Pkg️I chose pkg string here so you can check out how the documentation formatting is language and already with examples that can be executed by the browser everything to facilitate learning and understanding Editors and IDEThis link is about the IDEs and Editors that you can use when you have Godando The Go language doesn t need much for us to be able to edit our codes but we have some interesting plugins to make our day to day even easierEditors and IDE️This link will not have Sublime and nvim which are two editors that I use around here on a daily basis sublime by the survey survey only use sublime and vim nvim is a plugin that they will use in vim The darling and adopted by the Go team is VsCode with adherence Strengths of the Go languageBefore we do our famous “Hello World let s show some strengths of the Language let s preview the pillars and characteristics of the Go language PillarsWe have some well defined pillars in Go this will help you to further clarify your horizon when it comes to Go SimplicityLegibilityProductivityThis has become over the years something so standard for those who are developing in the Go universe that it sounds like poetry to the ears We know that go is an attempt to join two different worlds the world of compiled languages ​​with interpreted languages in the idea was born and with the objective of creating a new programming language Main featuresIn Go we have some outstanding features of the language that make it even more powerful for developing web applications for servers Only keywordsLow learning curveCompiled staticallyMultiplatforms now support RISC VConcurrent ParadigmStatic TypingBackward CompatibilityAll these points make the language even more interesting the team of engineers that developed the language did an excellent job or better see doing it Go is simply fantastic some don t like its designer but it s understandable more than years developing in OO and Functional paradigms as if there is no life on another planet is understandable Installing GoThis is the moment we ve all been waiting for get your hands dirty and install locally on the official website you can t go wrong there s nothing simpler than installing Go on your machine so you can program in Go Taking advantage of this and making it clear that We don t need to install Go on the server this is exactly what you read on your server whatever it may be On premises an Ec from Aws or a pod on ks whether it s on Gke or ks from DigitalOcean that is on ECS or EKS whether it is a serverless or on any hosting server of your choice what you will need is the binary whether in a docker image for example or not This is one of the strengths of Go we don t need to carry stuff to the server this is one of the great benefits of using Go in web applications on servers and this is what Go became known for like the containers language Knowing all this let s go to install Go and see how complex it is just kidding…Install Go in this link you will have the step by step on how to install in different Operating Systems but I will leave the installation in Linux here Installation on LinuxIf you have a previous version of Go installed be sure to remove it before installing another one sudo rm rf usr local goDownload the file by clicking here go and extract it in usr local sudo tar C usr local xzf go linux amd tar gzAdd usr local go bin to the PATH environment variable export PATH PATH usr local go binTo make what we did above global that is every time you enter your terminal “go is executed you can do this by adding the following line that I showed above to your HOME profile or etc profile for a system wide install or your bash or whatever you re using in your Linux environment Note Changes made to a profile file may not apply until the next time you log in to your computer To apply the changes immediately just run the shell commands directly or run them from the profile using a command like source HOME profile Verify that you have installed Go by opening a command prompt and typing the following command go versionIf all goes well you will see “go version go linux amd beautiful simply beautiful you can say very simple Hello WorldNow it s time for our first hello world using Go There s no secret we can use any editor we saw above and go to the top In Go we don t need to compile when we re having we can simply run our programs without having to turn them into binaries ie compile go run main goBelow is our first hello world and just save the file with the go extension and put the name “ main go then just run it with the command “go run main go in our example I called file from “main go package mainfunc main println My first Hello World package mainimport fmt func main fmt Println My first Hello World go run main goThis hello world of ours is the smallest structure we can assemble to output to the terminal To be a little clearer when using the println function we have to know that it is a built in function at runtime that can eventually be removed while the fmt package is in the standard library which will persist go buildNow let s turn it into a binary let s compile it and for that we will use “go build or “GOARCH GOOS linux go build o myprogram main go we are now informing the architecture and operating system that we want to compile our Go program GOARCH GOOS linux go build o myhello main goThis command will make the build it will generate an “executable a binary to run on your operating system Very easy isn t it I would say very beautiful With this binary you ll be able to run it on your machine or on any server that has the same architecture and operating system that you made for your compilation It s important to always emphasize this detail “We don t install anything Go on our web servers is exactly what you read you don t need to install anything you just need the binary ️This is why Go became known as the Language of Containers Are you saying this isn t fantastic To run a web application on your server just send the binary to it Wow that s right just from the binary without needing to take anything else related to your project at all Go and DockerSince we are talking about docker and saying that we only need the binary to run our project on Go let s present what our image would look like using docker so that we can now use Go on servers like Google s GKE AWS s EKS or ks from DigitalOcean or simply use with docker Dockerfile distroless FROM golang as builderWORKDIR go src mainCOPY RUN CGO ENABLED GOOS linux go build o main main goRUN cp main go bin main STEP build a small image FROM gcr io distroless baseCOPY from builder go bin main CMD main Look how beautifuljust under lines We have a Go image so we can compile our project and then we do something like Scratch but we are using distroless which is a very small lean base and contains our binary I m sorry but isn t this fantastic or simply beautiful️ The distroless concept is simple it assumes that we focus on our application and less on the Linux distribution Now let s make a small example of a rEST API just to exemplify our Dockerfile and show in practice how simple it is to upload a docker image of our project package mainimport log net http func main mux http NewServeMux mux HandleFunc api v ping Ping log Println Run Server log Fatal http ListenAndServe mux func Ping w http ResponseWriter r http Request log Println server ok w WriteHeader http StatusOK w Write byte msg pong Now we just build our project with the following command docker build ーno cache f Dockerfile t jeffotoni apisimplego latest this will generate an image locally on your machine and now just run it for us to test docker run ーrm ーname apisimplego p jeffotoni apisimplegoReady now just shoot to our api v ping endpoint that we created curl i localhost api v pingSay it s not beautiful ConclusionThis post is a simple summary for you who would like to increase your web programming arsenal I hope you enjoyed The channel
