Go for Web Development The Go Programming Language

Golang seemed like a reasonable choice since we were also looking towards a service-oriented architecture. We are using it to build microservices that are specific to our business needs, like advertising, authentication and creatives. Each of these services is loosely coupled, independently deployable and manageable.

Go is designed to enable developers to rapidly develop scalable and secure web applications. Go ships with an easy to use, secure and performant web server and includes it own web templating library. Go has excellent support for all of the latest technologies from HTTP/2, to databases like MySQL, MongoDB and Elasticsearch, to the latest encryption standards including TLS 1.3. Go web applications run natively on Google App Engine and Google Cloud Run or on any environment, cloud, or operating system thanks to Go’s extreme portability. Golang, or Go, is a compiled, statically typed programming language designed by Google. Another potential downside to Go is the size of the generated binaries.

Understand the strengths, weaknesses, use cases, and future directions of Google’s hit programming language.

Some languages arrange to make that guarantee at compile time. Method dispatch is simplified if it doesn’t need to do type matching as well. Experience with other languages told us that having a variety of methods with the same name but different signatures was occasionally useful but that it could also be confusing and fragile in practice. Matching only by name and requiring consistency in the types was a major simplifying decision in Go’s type system. We debated this issue but decided implementing len and friends as functions was fine in practice and didn’t complicate questions about the interface of basic types.

  • To conclude, Go is quickly changing for the best, and it is enabling companies to scale and optimize their business.
  • One of the primary developers of GO was a Brian Kernighan, who also happend to be one of the inventors of the C programming language.
  • Netflix’s web developers were looking for a faster programming language than Java and less time-consuming than C.
  • As a dev, I’ve been able to pick up languages and frameworks over a long weekend.
  • So I don’t understand why you say that Kernighan made go after learning from his mistakes in C.

If you’re a developer familiar with Go, this practical book demonstrates best practices and patterns to help you incorporate concurrency into your systems. Things like excluding generics was by design to keep the language simple. And it’s verboisty is initally annoying but also https://www.globalcloudteam.com/ why it’s commpeting at an enterpise level. The verbosity adds clarity for future maintainers of unkown skill level. Working on Ruby or PHP projects where previous developers have tried to be “clever” making everything magic, you have a hard time writing obfuscated code in Go.

Go is fast

The error example is easy to express using an interface value to hold the error and a type switch to discriminate cases. The syntax tree example is also doable, although not as elegantly. Since the earliest version of the language, there has been considerable thought into how best to expand the identifier space to accommodate programmers using other native languages. Exactly what to do remains an active topic of discussion, and a future version of the language may be more liberal in its definition of an identifier. For instance, it might adopt some of the ideas from the Unicode organization’s recommendationsfor identifiers. Whatever happens, it must be done compatibly while preserving the way letter case determines visibility of identifiers, which remains one of our favorite features of Go.

The CPU overhead averages about three cheap instructions per function call. It is practical to create hundreds of thousands of goroutines in the same address space. If goroutines were just threads, system resources would run out at a much smaller number. One of the most successful models for providing high-level linguistic support for concurrency comes from Hoare’s Communicating Sequential Processes, or CSP. Occam and Erlang are two well known languages that stem from CSP.


We would like to thank you for taking the time to visit us today. We hope that you will find the information provided to be both helpful and informative. Please stay with us and read on as we share some what is Golang valuable tips that we believe you will find useful in your daily life. But this is relatively new compared to the most traditional languages like Java and Python, which were released in the 1990s.

One of Golang’s biggest advantages is that it offers the clarity and ease-of-use that other languages lack. Golang’s advantages make it easy for new programmers to quickly understand the language and for seasoned veterans to easily read each other’s code. There’s no surprise that the likes of Kubernetes, Docker, and Heroku are using Go because cloud-based programming is one of the main reasons why Go was designed. The Go programming language was borne because things were getting much more complex in the codebases within Google.

In Go 1, unlike prior releases, equality is defined for structs and arrays, so such types can be used as map keys. A related detail is that, unlike in C, int and int64are distinct types even if int is a 64-bit type. The inttype is generic; if you care about how many bits an integer holds, Go encourages you to be explicit. Untagged unions would violate Go’s memory safety guarantees. Similar situations to those described here can arise whenever interfaces are used. Just keep in mind that if any concrete value has been stored in the interface, the interface will not be nil.

Twitch uses Go for its chat, which delivers hundreds of billions of messages daily. Its Web APIs, Search and Discover services, revenue systems, and administrative tools are also written, at least in part, in Go. Google was rapidly growing then, and the code its engineers were using, C++, was difficult to manage and overly complex. The simplicity of the language makes for easier code review and debugging, while the philosophy of leanness in libraries also eases debugging. Meanwhile, the inclusion of all dependencies in the compiled binary makes for simple deployments.

Why build concurrency on the ideas of CSP?

Statically typed programs won’t start up until errors have been fixed, while dynamically typed languages like JavaScript will start up even if they have errors. Interfaces are a class of types and provide a limited form of structural typing in the otherwise nominal type system of Go. An object which is of an interface type is also of another type, much like C++ objects being simultaneously of a base and derived class. Go interfaces were designed after protocols from the Smalltalk programming language. Multiple sources use the term duck typing when describing Go interfaces. Although the term duck typing is not precisely defined and therefore not wrong, it usually implies that type conformance is not statically checked.

APIs, database servers, and web application architectures are only a few examples. Cloud computing is a critical component of today’s digital software architecture. One can develop software systems that are readily scaleable and sharable with cloud services.

Also, because Go is platform-independent by design, it’s unlikely any of these will become a part of the standard package set. Go, also called Golang or Go language, is an open source programming language that Google developed. Software developers use Go in an array of operating systems and frameworks to develop web applications, cloud and networking services, and other types of software.
