Advantages of Using Golang for Your Next Web Application Project

Leave a Comment / Uncategorized /

At a time when there are wide spectrums of programming languages, the mobile and web app developers choose the one that suitably fits best into the project. You can also say that the developers may also opt for the programming language based on their preference and expertise. However, amid all, Golang or the Go programming language developed by Google has come to the forefront. It’s not that Go is a recently introduced language. It has already made its inception in 2009, which is close to a decade. According to the TIOBE Index for Go, there has been a steady increase in the popularity of the Go language in September 2017, compared to the previous year. It ranked the 17th position on the monthly list jumping two places higher from the 19th position. In fact, according to a report published on a website, Google’s Go has outperformed some other major players including Java, C, and Python programming languages. This useful information is quite interesting to note and at the same time will also encourage other developers to choose Go language in their next project. But before we dig into what advantages does Golang offer, let’s shed some more light on the programming language. One has to credit the trio Robert Griesemer, Rob Pike, and Ken Thompson; the Google engineers for developing this amazing language. It is basically a statically typed, syntactically, and compiled language, which is quite similar with the C. Its major benefits include memory safety garbage, CSP-style currency, and structural typing along with the others, which would be discussed shortly. One can estimate the popularity of the Go programming language from the fact that some top-notch giants including Google, IBM, YouTube, Twitter, Facebook, and Docker etc are using this programming language. Indeed, some of the big media houses such as BBC, The New York Times, and The Economist are also not lagging behind in employing the Go language. GoDoc Offers Easy and Good Documentation We are aware that documentation plays a crucial role in application coding and one should always try to simplify the process. Now, Golang offers the advantage of the GoDoc, which is known to be more than a useful tool in developing the documentation pages. It offers static coding and the developer feels blessed because he does not have to use any other additional languages such as JavaDoc, PHPDoc, or JSDoc for the annotation of development. Merely using simple English is enough. It is interesting to note that GoDoc is the single documentation engine, which is employed by the entire community. Another important point is that each of the application or the library available in Go uses the similar format of documentation saving a lot of time in this process. Offers Enhanced Performance It has been indicated earlier that Go has performed much better in comparison to the other programming languages including Python. In fact, Golang is even faster than the Python version 2 and 3. One of the obvious reasons why Go has performed well is due to the presence of higher CPU scalability and concurrency model. Goroutine also offers affordable resources as against Python Threads, which is about 10 times more costly if you have to process some internal request. This definitely will save your resources or the Memory CPU. Can Compile into a Single Binary Go is basically more of a complied language and the Google engineers have done something commendable. It combines the entire dependencies, libraries and modules in one binary depending on the Operating System and architecture you are using for the static linking process. For example, if you have a Linux X86 CPU in your laptop, and you want to compile your backend application, you will have to only upload the compiled binary into the server and there is no need to install the dependencies. Go Does Not Need Web Frameworks Go is an amazing programming language developed in a unique manner so that it does not require any support of the third-party library or the web frameworks. This is mainly due to the fact that it contains wide range of tools, which receive ample support from the native language core. We can cite the examples of http, html, json, and templating built-in native languages. This helps for building complicated API services without the need to search for the library on GitHub. Assistance for the IDE and Debugging When you want to switch or replace your programming language, you would need the IDE extensive support. In fact, IDE is a great software development application and asset that can reduce your coding time up to about 80%. For instance, you have Go Plugin For JetBrains IDEA support the Webstorm, PHPStorm, etc. You would receive full and comprehensive help from the plugin while working on the project development. Benefit of Static System If you are into building a large scale and complex application, then you would need the support of type system. Again here Go proves superior than Python as it later may have some issue with using of variable as an integer and getting string as an outcome. However, Golang is there to solve the issue as it gets familiar about it during the compilation time as a compiler error. Golang is an Open-Source Language One of the factors that go into the favor of the Go programming language is the open-source. The fact that it was introduced by none other than Google also becomes a major plus point for the Go. Google had released it with the aim of simplifying the complex development process and to also meet their cloud expectations. Certainly, there cannot be a doubt that it has been highly successful. The developers can also use the programming language Go for building gaming apps as well along with various software development. Go is Quicker on Many Fronts Golang is one of those integrated languages that offers you speed and accuracy on many fronts whether you are writing codes for a program, compiling the codes and documents, deploying

Decoding Why GoLang Stands Apart from the Other Languages

Leave a Comment / Uncategorized /

With the insurmountable proliferation in technology, the world is also moving to unearth some of the most ground-breaking discoveries. GoLang, being one such revolutionary discovery, has taken the entire world by storm. As GoLang marched into our lives, people have discovered several ways to bring advancements and innovation in the field of development. Among legions of other programming languages claiming to fame, GoLang has proven to be the biggest game-changer. Although it’s true that for a beginner this new-age programming language might seem a tad bit complex and tough to handle, with adequate practices, one will be at ease to deal with GoLang. There is enough reason to go bonkers over this highly advanced programming language, but prior to demystifying them get acquainted with some basic facts about GoLang. So, without any further ado, let’s dig in this informative excerpt. GoLang – an Ocean of New Possibilities Can you believe that the popularity of GoLang has skyrocketed quite exponentially over the past few years? As a cutting-edge and result-driven programming language, its efficacy has caused a stirring ripple all over the globe and most rightly so. While several other languages like C, Java, etc. have continued to rule over the field of programming, several new models have been introduced that can spell better results for the modern computing, especially in the cloud. The increasing popularity of Go mainly owes to its lightweight and the fact that it’s suitable for almost every micro-services architecture. Container darling Docker, as well as Google’s Kubernetes, are also built with the usage of Go. In addition to such incredible popularity, Go is also holding the ground in data science owing to its advantageous features, which the data scientists are looking to utilize to bring in more effective results. Being a highly advanced programming language, GoLang can facilitate the developers in different ways, which also include native concurrency, garbage collection, and the likes. While using Go, a developer needs not rely on several other native capabilities to minimize the necessity of writing codes to fix memory leakage, etc. Some of the other features offered by GoLang can fit impeccably with data science and microservices architectures. Because of these aforementioned perks, Go is increasingly being adopted by legions of budding companies all over the globe. An Application Programming Interface for the Tensorflow has been included, and products such as Pachyderm are being crafted with the use of Go. There are a string of parts of Cloud Foundry that have been written in GoLang as well. And, the fun fact is that this list is regularly adding different names that have been written with the help of Go. What Makes GoLang Absolutely Irreplaceable? It was not very long that GoLang had set its journey to bring a dash of improvement and also alleviate some of the long-standing issues of the development industry. In the quest of providing the millennial developers a unified and seamless experience of development, Go came into being, and with each passing day, it’s carving a niche for itself undoubtedly. But, is it worth the entire buzz? Is Go truly irreplaceable? Is it capable of staying ahead of the curve? Let’s find out! Simplicity is the Major USP of GoLang Simplicity is unbeatable and GoLang has certainly taken it to a whole new level. Many successful programming languages such as Rust, Scala, etc. are rich in different complex features. Also, they have spelled amazing results in development by having provided advanced memory management and type systems. These programming languages have certainly taken the mainstream languages of their time such as Java, C#, C++, etc., and boosted their overall capabilities. Having taken a somewhat different and easier route, GoLang has successfully eliminated a lot of such features, albeit, for all the right reasons. Below are listed some of the features and capabilities that Go has eliminated: No Generics Generics or templates hint at the mainstay of different programming languages. By adding the complex and error messages related to generics, they can often be obscure to understand. By having decided to skimp on this part, the Go designers have made it easy to work with it. Undoubtedly, it has been a very controversial yet a wise decision taken by the designers. Single Executable There is actually no separate runtime library in GoLang. It is capable of generating a single executable that one can deploy simply by copying. Thanks to this for eliminating the risk of version mismatches or dependencies. Also, it could be a great boon for container-based development projects. No Dynamic Libraries There has been a slight tweak in 1.8 version of GoLang, as now the developers can load dynamic libraries in it by plug-in packages. But, as this feature was not in GoLang from the get go, it’s still considered as an extension for the special features. Go Owes its Popularity to Goroutines From a very pragmatic point of view, Goroutines is deemed as one of the most attractive aspects of GoLang. It can enable the experts to harness the capabilities of multicore machines in a convenient way. CSP The foundation of GoLang’s concurrency model is C. A. R. The prime idea is to delude any kind of synchronization over the shared memory between several threads of execution that is labor-intensive and error-prone. Synchronize Goroutines Another effective way to wait for goroutines is to use sync groups. One can declare a wait group object and subsequently pass it to each goroutine that is responsible for calling its Done() methods when it’s completely done. Channels Channels can allow goroutines to exchange information with ease. One can create a channel and pass it on to a goroutine. The user can not just write to the channel, but also read from it. Handles Error Seamlessly The entire concept of error handling is handled differently by GoLang. By convention functions, GoLang will never fail at returning an error as its final return values. Even though one cannot return errors from a goroutine, he/she can communicate them to the world outside via

To Go or Not to: the Pros and Cons of Programming in GoLang

Leave a Comment / Uncategorized /

‘Google’ of modern times has transcended itself in being versatile and more than just a search engine. It has penetrated the world of web services, information, entertainment and communication to deliver solutions that are a technological marvel each. Amid this surge, it has also not forgotten to contribute to the rising need for software productivity – the fine balance between the quantity of software developed and cost incurred. Conceived in 2007, GoLang counts as one of Google’s many such breakthrough initiatives which have made the world of programming a lot simpler. A Little History of GoLang The idea for this open-source programming language came up when Google engineers Robert Griesemer, Rob Pike, and Ken Thompson huddled together to create a systems level language. The focus was on resolving the difficulties of other programming languages in writing codes without doing away with their characteristic features. Accordingly, GoLang bases on the classic syntax of C/C++ with added benefits of garbage collection, memory safety, automatic declaration of variables, structural typing, and CSP-style concurrency. This is also the latest programming language that keeps multi-threading at its core. With the whip hand over its competitors, GoLang has meteorically risen up the Tiobe Index – one that indicates programmer preferences and favorites. No wonder it is being used in diverse applications worldwide, including Dropbox, SoundCloud, Cloud Foundry any many others! The question is, is GoLang really worthwhile? What makes it better than stalwarts like C, C++, Java and Python? Why choose it at all? Let’s find out the pros and cons of it. Simplicity and Ease of Use Pro: The simplest reason to start programming in GoLang is its simplicity. The syntax is extremely small and easy to learn. Because its core resembles that of C/C++, experienced programmers can pick up the basics fast. Although it lacks the functionality of other programming languages, its scope has been deliberately limited to keep it simple. Furthermore, for those trying and failing at multithreading codes, GoLang is a safe haven for background coding tasks. Con: Although simple to use, GoLang makes room for undisciplined coding. Also, this simplicity, which the language flaunts, can become an obstacle when a project matures into something bigger. It would then be unwise to ignore the other cleverer programming languages that have better bug-fighting abilities. For those looking for generics, exceptions and extensibility this programming language would be disappointed. Virtual Machine Dependencies Pro: Regarding virtual machine dependencies, GoLang offers peace of mind. Codes written with this programming language are complied into a binary that is ready to go and doesn’t need a virtual machine. Simply enter the executable’s name in the command line and hit Return. In short, dependencies are not an issue with GoLang because it comes with a dependency manager. As virtual machines are not involved in running codes, any software developed using this programming language would feed on fewer resources. Above all, GoLang enables faster debugging cycles. Con: The standalone binaries of GoLang are huge because they need to include the power of the virtual machine as well. Even a small ‘hello world’ might eat up 2MB of data. Of course, much has been done to compress the binaries by excluding uncalled methods. Still and all, the RAM might end up clogging when a server fires up multiple versions of your code. Furthermore, GoLang allows dependencies to be expressed within the same file that contains the dependent code. Although this is a good thing, no programmer can indicate a specific version of the dependencies. The task is restricted to the latest version, also known as the master branch. This eventually causes errors, including the breaking of codes because of dependency alteration. Automation Pro: As discussed earlier, GoLang comes with features like automatic declaration of variables, fast compile times, and latency free garbage collection. It completely keeps away manual memory management. Such automation eventually saves time. Con: Ask any programmer and he would tell you about the pitfalls of using automation features in programming languages. What if garbage collection is triggered at the wrong time leading to errors and delay in server code responses? What if the same variable name gets used in nested scopes and automatic declarations goof it up? Imagine the chaos! Doesn’t the belts-and-suspenders approach seem more logical? Classic Syntax of C Pro: C lovers consider GoLang to be the next update. Carrying the classic syntax, this programming language has everything that reminds you of C, of course, without the annoyances. Features like latency free garbage collection and a simpler file structure make the difference. Everything else is quintessentially C! Con: There are other programming languages as well that resemble C. Consider the likes of Java, Swift, Rust, C#, C++, and even Objective-C. Moreover, programming isn’t only about defining basic blocks in compiler construction or fancying curly braces. And even if it is, other programming languages have so much more to offer. Syntax Libraries Pro: GoLang has some standard libraries with built-in functionality that lets programmers write code quickly. These libraries are updated and ready to go – a plus point for conservative developments. Con: Despite the fresh libraries, GoLang lags behind because most programming languages are already ahead of it. When old is gold, why would people want to bet on something so nascent? In a Nutshell… Things You’ll Love About GoLang: It’s simple and compiles at ninja speed. Programs can be edited and run directly on the web. Memory management isn’t a problem as this is a garbage collected language. It’s the only programming language that has a standard library with a fully working web server. It is supported by Google and enables large-scale software engineering. Things You’ll Hate About GoLang: It’s a relatively new language with not many libraries or information. Its simplicity seems superficial because of its internal inconsistencies. With limited scope, automation can invite errors. It’s got defective dependency management. It’s a high-level language with low-level features. To be honest, GoLang is something that would shatter you and still satisfy you. Blog Source-

The buzzing programing language in an IT Industry is Golang, which has been seen in the limelight due to its intelligent features, good community support, and great documentation. These days, more developers are getting involved in the Golang usage due to its fame and high pay scale in dominant countries. Here we present a report to support this statement. The above image indicates a steep rise in the involvement of developers in the GO language. Though good documentation and intelligent features of Golang could help developers in learning language effectively and applying it productively still, Golang is missing with the common structure to quick start any API Structure. We at MindInventory have proficient Golang Development team who encountered with a requirement of having an effective Integrated GoLang API Development Structure while working on several Golang Projects and as a result of which they came up with one. It is a kind of “Get Started Kit” where one can find all required components in a single package and need not to set up each time they start with any crucial work. As it’s known, Golang is server-side language and one needs to have various components working and interacting with one another. It’s really cumbersome and wastage of time while adding each separate components and settling it down every time you have to work on and it’s better to go with one common structure where you get all settled as per well accepted coding standards. Now, by going straight, let’s see how to use this Golang API Skeleton with Fully Managed Versions to kick start Golang project. Prerequisite One need to install latest version of Go i.e 1.12 (Released in Feb 2019) from https://golang.org/dl/ and setup GOROOT and GOPATH. Steps to Follow For running the server you have to run following command in the terminal. $ go run main.go It will start your server at the port you have mentioned in the .env file. To run the server in a port other than the default, run following command $ go run main.go <specific port> To create a build for your project and upload in the server, one need to run following command. $ go build Let’s go through each component to know all about it. API Helpers It is a component which contains helper functions which returns API responses, HTTP status codes, default messages and other, etc. Controllers It is a component which contains handler functions which handles particular route need to be called when there are any API requests from the client machine. Helpers It is a component which contains common functions which are called helper function which is generally required in all APIs one creates. Middlewares It is a component which provides a convenient mechanism for filtering HTTP requests and one can add as add required middleware in this component. Models This is a component where database structure is created which is used while Database Migration. Resources Resources contain all structures other than models which can be used as responses. Routers It is a component where resources define the routes for the project and are used by the controller to handle the incoming request. Seeder It is a component which adds seeding data (dummy data) while creating a database. It is an optional component but generally used to test the model. Services This is the main component where all the core APIs for projects resides and one writes all APIs in this section. Storage It is a component where data is stored to which is generally termed as Database. It can handle all type of data i.e SQL like MySQL, MariaDB, and PostgreSQL whereas NoSQL Database like MongoDB. Templates It is a component which contains the HTML templates to be used in the project. .env It is a file which contains environment variables. In this way, you can straight start your project with Golang for API creation and need not spent time in project set up. Blog Source- https://www.mindinventory.com/blog/golang-project-structure/

Golang vs Python: Which Programming Language will Suit your Business?

Leave a Comment / Uncategorized /

Choosing the most suitable programming language for your business is a diplomatic decision indeed. Prior to the commencement of any project, the development teams are likely to discuss which programming language complements their needs. With too many options available, it becomes a tough move to shortlist the most relevant ones. You have C++, PHP, JavaScript, Go Language, Python and several others lined up before you. When you broil down these choices, you would end up with Golang and Python in most of the occasions. Although Golang and Python are similar in a number of ways, their functional features vary significantly. Here, you will get a comprehensive insight into these two programming languages: Golang vs Python. This will help you understand when to use them, and how each of them can help you. Python Performance and Statistics Python presently occupies the first position in the IEEE Spectrum ranking. The growth of Python web development has been incredible, and it is among the top six most extensively used programming languages. Have a look at the factors leading to the popularity of Python: Python comes with a long list of libraries, such as Pandas, Tensorflow, Scikit-learn, Pandas, Keras, NumPy and SciPy. This reduces the cost of the development cycle of the initial stages, besides saving time. Since Python is easy to apply, it is a great choice for startups. Eventually, it has emerged as one of the programming languages that are most easily accessible. The developers can seamlessly understand its syntax. Particularly, when you build datasets and analytical tools, Python appears to be your best choice. All these features make Python a vital language for software development. Golang Performance and Statistics A report published by GitHub reveals that Golang, as a programming language, is the fastest growing in 2020. Golang is an open source language, and lightweight in nature. Evidently, this makes it suitable for microservices software architectures. For instance, your e-commerce website receives customer’s orders, gets the inventory verified and ships the goods. In this case, each microservice is small. When you use Golang to build the website, the maintainability of the site improves significantly. The application will have better deployability and testability. Besides, in the previous quarter, the Golang industry has shown around 8.9% growth, along with a change of 1%. Have a look at the factors leading to the popularity of Golang: The Go Language is Cloud-native, and it is applicable for leading projects based on Docker and Ethereum. Since Golang is cross-platform, you can use a suitable operating system, when you compile the code. The developers can seamlessly install Golang and the quality of debugging is comparatively superior. These factors have led to the extensive popularity of Golang. Golang Vs Python: The Comparison Between Two Programming Languages The following parameters have been used in the comparison between the two popular programming languages: ogramming languages: Performance Scalability Applications Libraries Executions Golang Vs Python: Performance Golang is fast, and since the language is compiled, the developers can interpret it faster. Python, on the other hand, is an interpreted language and not as fast as Golang. However, you might not consider speed as the most important factor in your software development process. Python is fast enough to develop software within a standard completion time. It is not likely that performance issues will pop up, unless you achieve a significant scale. In terms of dealing with concurrency, the approach is different for the two languages. For concurrency, Golang has a built-in support and it is resource-efficient. It also uses the goroutines, which do not demand much of the memory and CPU. On the other hand, Python does not come with an inbuilt support to deal with concurrency. Instead, it depends on a concurrency library and therefore, it has a lower level of efficiency. Python vs Golang: Scalability The scalability factor was considered while developing Golang. Its purpose was to assist developers working at Google resolve issues at the scale of that particular company. Evidently, it involves thousands of programmers who work on large server software, which was hosted on several clusters. Therefore, Golang comes with a built-in support for concurrency. On the other hand, Python finds it difficult to deal with concurrency and it uses threads to implement parallelism. Concurrency indicates that an application is able to deal with more than a single task simultaneously. Parallelism indicates that the task is split into smaller parts by an application. This can then be processed in parallel. Evidently, if your project is large and scalable, you should use Golang, as it comes with an inherent support for concurrency. Golang vs Python: Applications You should note that each programming language comes with a specific purpose. For instance, people primarily use JavaScript for web development. Python, likewise, is used for artificial intelligence, data analytics, web development and deep learning. It has some amazing libraries that make it easier to use the language. The developers mainly use Golang for systems programming. As it supports concurrency, it can also be used for cluster computing and cloud computing. Golang has gained a lot of popularity in web development, as it is easy to use the libraries and it is a powerful language. This allows the developers can set up the web servers in little time. Python vs Golang: Libraries As Python comes with a wide array of libraries and frameworks, it turns out to be a good choice for the developers. Two of the most popular web frameworks include Flask and Django. This helps the developers work on the web development process in a very short time. Python also brings you an enriched collection of libraries in particular areas like forensics and data science. This ensures that the prototyping process can be completed in quick time. Golang, in contrast, also comes with library support to an extent. However, it does not satisfy the developers to the extent that Python does. Some developers argue that Golang is difficult to use due to the absence of important frameworks. Using a framework

Is Golang Better than Rust? Let’s Find Out

Leave a Comment / Uncategorized /

Golang or Rust? For the millennial developers, dilemmas as these have taken their lives for a spin. Brimming with a number of advantages, both these programming languages have created a stirring ripple the world across. Over the past few decades, these programming languages have emerged the prime options for enterprise development. Rust was churned out at Mozilla, while on the other hand, Golang was created at Google. These programming languages provide indispensable features for developing advanced software including, memory safety, integrated tool-chain, open-source development model, strong communities for modern users, and the likes. Even though Golang and Rust have an array of similarities, they are dramatically different from each other. They were developed for scratching different itches, meeting different requisites, and writing different types of programs. Drawing a comparison between Golang and Rust is not about figuring out which programming language can perform better. Rather, it’s about determining which language can perform supreme at a given programming task. Bearing that fact in mind, we must find out the main ways Golang and Rust differ from each other and the kind of responsibilities each is satiable for. However, in order to understand which programming language is the best fit for your requisites, you should get an in-depth knowledge of Golang as well as Rust. Look into the following excerpt to demystify numerous unknown facts about them: An Introduction to Golang Golang or Go was introduced in the year 2007 by Google. It was conceived as a riposte to a few issues that some organizations were found in building software infrastructure. Certain problems like computation clusters, web programming models, etc. were handled by workarounds instead of getting fixed directly. Golang was conceptualized and built to bring more productivity midst such environments. Apart from its well-known aspects like garbage collection, built-in concurrency, the design consideration of Golang also include a rigorous dependency management, robustness across different boundaries between components, and software architectures’ adaptability as advanced systems. Presently, compared to other server-side programming languages, Golang shares the highest market position in terms of both traffic and popularity. As per the survey, Web Development is the most preferred domain among Golang users, standing at a whopping 65%. Also, the programming language is majorly used for writing API/RPC services (73%) and developing CLI applications (63%). Most of all, the promoter score of Golang is positive at 68%, which indicates its popularity is only rising. 90% users in 2018 said they are willing to recommend Golang to others. In the year 2009, Golang became public finally and began to be used as an open-source project. Some of its influential predecessors are Alef, Hoare’s CSP, Pike’s Newsqueak, etc. Recently, in February 2019, the 1.12 version of Golang has come up. Some of the biggest highlights of its latest features include an improved modular support, a better iOS and MacOS forwards compatibility, and the likes. The Major Advantages of Using Golang The best asset of Golang has to be its incredible speed. It is a very fast and statically-typed programming language that can compile to machine code. In fact, Golang can work faster than many other programming languages like Python, JavaScript, Java C#, etc. The simplicity of code is another perk of using Golang Golang is known to be a pragmatic, concise and efficient language Golang’s explicit focus is to streamline the process of coding. In the documentation of Golang, it is depicted as an ‘open-source project’ for making programmers more productive Its problem-solving approach is mainly emphasized on a programmer’s productivity across different software development cycles Flexibility is another biggest strength of Golang It is focused on concurrency as a top-tier concept It is simple as well as extremely safe to use. It will not tolerate unprotected memory access It can excel at writing straight-forward ‘DevOps’ tasks and micro-services It has a strong interoperability with C as well as several other programming languages One of its rumored objectives was to substitute C++ and C Golang is IDE-supported Last, but not the least, it is extremely simple to handle Disadvantages of Golang Although Golang has earned a great deal of appreciations from the developers worldwide, it has a number of drawbacks as well. Some of the major pet peeves of Golang are dug out down below: It is not a system language It sacrifices a few aspects of performance to put an emphasis on its objective of simplicity It lets some interoperability via cgo. It is not the anticipated way for Golang programs to be written Golang lacks generics to a great extent There is not enough immutability in this programming language Go is garbage collected that takes a toll on its overall performance A Brief Overview of Rust Rust came into being in the year 2010. Often, it is deemed as an advanced extension of the ML languages. Mozilla was the actual underwriter of Rust. The Servo browser engine which is sponsored by Mozilla was developed with the help of Rust. Some of the major objectives of the Servo project which leverage the ownership and concurrency of Rust include better security, improved parallelism, better performance, and increased modularity. A market survey by Rust shows 74.5% users who have used the programming language, prefer it, too. In fact, the number of Rust users was reported to increase in 2018 with nearly a quarter of them using it for at least 2 years. Also, Rust projects are trending in mammoth sizes with large investments. Also, medium investments exceeding 10K and large investments exceeding 100K lines of code were reported to grow to 23% in 2018 from 8.9% in 2016. This is huge! However, when surveyed about Rust at work, the programming language showed some not-so-satisfactory statistics. 49.2% companies said they don’t use Rust at work. Those who do are only part-time users at 21.2%. And, those who use it full time stand at only 8.9%. The 1.0 version of Rust was introduced in 2015 and the 1.33 version of Rust was built in 2019.

Steps to Follow to Use WebSockets in Golang

Leave a Comment / Uncategorized /

We usually send a message and receive an immediate response without refreshing a page. However, earlier, allowing real-time functionality was a big challenge for app developers. After undergoing HTTP long polling and AJAP, the community of developers has ultimately discovered a solution to develop real-time applications. WebSockets have come as the solution to this issue and made it possible to create an interactive session between a server and browser of a user. WebSockets enable a browser to send messages to a server and get event-driven responses. And there is no need to have to poll the server for a reply. Currently, WebSockets are the top-notch solution to develop real-time apps: tracking apps, instant messengers, online games and more. This step-by-step guide discusses how WebSockets work and how to build WebSocket apps in the Golang language. Let’s just read on! What are WebSockets? WebSockets are upgraded HTTP connections that sustain until the client or the server kills the connection. Through the WebSocket connection, it is possible to perform duplex communication that is an extravagant way to say communication is possible from-and-to the server from the clients utilizing this single connection. The best aspect of WebSockets is that they utilize one TCP connection and the entire connection is built over this single durable TCP connection. This extremely lowers the amount of network overhead needed to develop real-time apps with the use of WebSockets since there is no continuous polling of HTTP endpoints needed. How to Build a WebSocket App in Golang? Here are some important steps that you must follow to write an easy WebSocket echo server depending on the net/http library: Step-1: Setting up a handshake At first, you need to form an HTTP handler using a WebSocket endpoint: Next, run the WebSocket structure. The client always sends the first handshake request. When the server authenticated a WebSocket request, it has to reply with a response of a handshake. Remember that you cannot write this response with the use of http.ResponseWriter, because it will disconnect the basic TCP connection if you begin to send the response. Hence, you have to utilize HTTP Hijacking that enables you to maintain the basic TCP connection handler and bufio.Writer. This provides you with the scope of reading and writing data without preventing the TCP connection. To accomplish the handshake, the server needs to respond with the relevant headers. “Sec-WebSocket-key” is randomly created and is Base64-encoded. After accepting a request, the server must add this key to a fixed string. Suppose that you have the x3JJHMbDL1EzLkh9GBhXDw== key. In this matter, you can opt for SHA-1 for computing the binary value and Base64 for encoding it. You will receive HSmrc0sMlYUkAGmm5OPpG2HaGWk=. Utilize this as the value of the Sec-WebSocket-Accept response header. Step-2: Transferring data frames Once you complete the handshake, your application can read and write to and from the client. The Specification of the WebSocket describes a particular frame format that is utilized between a server and a client. The image below showcases a little pattern of the frame: To decode the client payload, use the following code: In order, these code lines enable to encode data: Step-3: Closing a handshake When one of the client parties sends a close frame alongside a close status as the payload, a handshake is closed. Spontaneously, the party that sends the close frame can also send a close purpose in the payload. In case the client initiates the closing, the server must send an equivalent close frame in turn. List of WebSocket Libraries Many third-party libraries simplify the lives of developers and amazingly aid working with WebSocket apps. STDLIB (x/net/websocket) This WebSocket library belongs to the standard library. It applies a server and client for the WebSocket protocol. You don’t need to install it and it contains good official documentation. However, on the other hand, it doesn’t have some features that can be discovered in other WebSocket libraries. In the STDLIB (x/net/websocket) package, Golang WebSocket applications don’t enable users to use I/O buffers again between connections. Gorilla In the Gorilla web toolkit, the WebSocket package features an examined and complete application of the WebSocket protocol and a consistent package API. This WebSocket package is easy to use and properly documented. And you can find its documentation on the official website of Gorilla. GOBWAS This is a small WebSocket package that contains a strong list of features, like a low-level API that enables to develop the logic of custom packet handling and a zero-copy upgrade. GOBWAS doesn’t need intermediate allocations during I/O. Moreover, it features high-level helpers and wrappers around the API in the WsUtil package, enabling developers to begin quickly without examining the protocol’s internals. Although this library comprises of a flexible API, it comes at the cost of clarity as well as usability. You can find its documentation on the GoDoc website. GOWebsockets This Golang tool provides an extensive array of easy to use features. It enables for setting request headers, compressing data, and controlling concurrency. It assists proxies and subprotocols for transmitting and getting binary data and text. Moreover, developers can either enable or disable SSL verification. The documentation for and instances of the ways of using GOWebsockets are available on the GoDoc website. Wrapping Up This tutorial has covered some of the fundamentals of WebSockets and how to develop an easy WebSocket based app in Golang best tools. Besides the aforementioned tools, some other alternative applications enable developers to develop strong streaming solutions. They include Package rpc, gRPC, Apache Thrift, and go-socket.io. The availability of properly documented tools like WebSockets and the continuous development of streaming technology make it simple for developers to build real-time apps.
