An Introduction to Go for non-Go Developers

Summary: I’ve presented an introduction to Go a few times for developers who are new to the language – this is that talk serialized as a technical article. It looks at why you might want to use Go, and gives a brief overview of the standard library and the language itself.

A few years ago I learned Go by porting the server for my Gifty Weddings side gig from Python to Go. It was a fun way to learn the language, and took me about “two weeks of bus commutes” to learn Go at a basic level and port the code.

Since then, I’ve really enjoyed working with the language, and have used it extensively at work as well as on side projects like GoAWK and zztgo. Go usage at Compass.com, my current workplace, has grown significantly in the time I’ve been there – around half of our 200 plus services are written in Go.

This article describes what I think are some of the great things about Go, gives a very brief overview of the standard library, and then digs into the core language. But if you just want a feel for what real Go code looks like, skip to the HTTP server examples.

Why Go?

As the following Google Trends chart shows, Go has become very popular over the past few years, partly because of the simplicity of the language, but perhaps more importantly because of the excellent tooling.

Here are some of the reasons I enjoy programming in Go (and why you might like it too):

  • Small and simple core language. Go feels similar in size to C, with a very readable language spec that’s only about 50 pages long (compared to the Java spec’s 770 pages). This makes it easy to learn or teach to others.
  • High quality standard library, especially for servers and network tasks. More details below.
  • First class concurrency with goroutines (like threads, but lighter) and the go keyword to start a goroutine, channels for communicating between them, and a runtime whose scheduler coordinates all this.
  • Compiles to native code, producing easy-to-deploy binaries on all the major platforms.
  • Garbage collection that doesn’t require knob-tweaking (optimized for low latency).
  • Statically typed, but has type inference to avoid a lot of “type stuttering”.
  • Great documentation that is succinct and includes many runnable examples.
  • Excellent tooling. Just type go build to build your project, go test to find and run your tests, etc. There’s CPU and memory profiling, code coverage, and cross compilation – all without external tooling.
  • Fast compile times. The language was designed from day one with fast compile times in mind. In fact, co-creator Rob Pike jokes that “Go was conceived while waiting for a big [C++] compilation.”
  • Very stable language and library, with a strict compatibility promise that all Go 1 programs will run unchanged on later versions of Go 1.x.
  • Desired. According to StackOverflow’s 2019 survey, it’s the third most wanted programming language, so it’s easy to hire developers who want to use it.
  • Heavily used in cloud tools. Docker and Kubernetes are written in Go, and Dropbox, Digital Ocean, Cloudflare, and many other companies use it extensively.

How long does it take to develop/build an app?

With more of us using smartphones, the popularity of mobile applications has exploded. In the digital era, the number of people looking for products and services online is growing rapidly. Smartphone owners look for mobile applications that give them quick access to companies’ products and services. As a result, mobile apps provide customers with a lot of benefits in just one device.

Likewise, companies use mobile apps to increase customer loyalty and improve their services. Mobile Developers are in high demand as companies use apps not only to create brand awareness but also to gather information. For that reason, mobile apps are used as tools to collect valuable data from customers to help companies improve their offer.

There are many types of mobile applications, each with its own advantages. For example, native apps perform better, while web apps don’t need to be customized for the platform or operating system (OS). Likewise, hybrid apps provide users with comfortable user experience. However, you may be wondering how long it takes to develop an app.

To give you an idea of how long the app development process takes, here’s a short guide.

App Idea & Research

app-idea-research

_Average time spent: two to five weeks _

This is the initial stage and a crucial step in setting the project in the right direction. In this stage, you brainstorm ideas and select the best one. Apart from that, you’ll need to do some research to see if your idea is viable. Remember that coming up with an idea is easy; the hard part is to make it a reality.

All your ideas may seem viable, but you still have to run some tests to keep it as real as possible. For that reason, when Web Developers are building a web app, they analyze the available ideas to see which one is the best match for the targeted audience.

Targeting the right audience is crucial when you are developing an app. It saves time when shaping the app in the right direction as you have a clear set of objectives. Likewise, analyzing how the app affects the market is essential. During the research process, App Developers must gather information about potential competitors and threats. This helps the app owners develop strategies to tackle difficulties that come up after the launch.

The research process can take several weeks, but it determines how successful your app can be. For that reason, you must take your time to know all the weaknesses and strengths of the competitors, possible app strategies, and targeted audience.

The outcomes of this stage are app prototypes and the minimum feasible product.

Developer Career Path: To Become a Team Lead or Stay a Developer?

For a developer, becoming a team leader can be a trap or open up opportunities for creating software. Two years ago, when I was a developer, I was thinking, “I want to be a team leader. It’s so cool, he’s in charge of everything and gets more money. It’s the next step after a senior.” Back then, no one could tell me how wrong I was. I had to find it out myself.

I Got to Be a Team Leader — Twice

I’m naturally very organized. Whatever I do, I try to put things in order, create systems and processes. So I’ve always been inclined to take on more responsibilities than just coding. My first startup job, let’s call it T, was complete chaos in terms of development processes.

Now I probably wouldn’t work in a place like that, but at the time, I enjoyed the vibe. Just imagine it — numerous clients and a team leader who set tasks to the developers in person (and often privately). We would often miss deadlines and had to work late. Once, my boss called and asked me to come back to work at 8 p.m. to finish one feature — all because the deadline was “the next morning.” But at T, we were a family.

We also did everything ourselves — or at least tried to. I’ll never forget how I had to install Ubuntu on a rack server that we got from one of our investors. When I would turn it on, it sounded like a helicopter taking off!

At T, I became a CTO and managed a team of 10 people. So it was my first experience as a team leader.

Then I came to work at D — as a developer. And it was so different in every way when it came to processes.

They employed classic Scrum with sprints, burndown charts, demos, story points, planning, and backlog grooming. I was amazed by the quality of processes, but at first, I was just coding and minding my own business. Then I became friends with the Scrum master. I would ask him lots of questions, and he would willingly answer them and recommend good books.

My favorite was Scrum and XP from the Trenches by Henrik Kniberg. The process at D was based on its methods. As a result, both managers and sellers knew when to expect the result.

Then I joined Skyeng, also as a developer. Unlike my other jobs, it excels at continuous integration with features shipped every day. Within my team, we used a Kanban-like method.

We were also lucky to have our team leader, Petya. At our F2F meetings, we could discuss anything, from missing deadlines to setting up a task tracker. Sometimes I would just give feedback or he would give me advice.

That’s how Petya got to know I’d had some management experience at T and learned Scrum at D.

So one day, he offered me to host a stand-up.
