Interacting with a GraphQL API with Golang

You might remember that I’ve done quite a bit of content when it comes to developing GraphQL APIs with the Go programming language (Golang). Heck, I’ve even written a book and published a course on the subject. However, in everything I’ve done thus far, I haven’t demonstrated how to interact with a GraphQL using Golang.

Sure, a lot of the time you’ll be using something like React, Angular, or Vue to interact with your web service, but that doesn’t mean you’ll never need to query a GraphQL API from Go or execute a mutation.

In this tutorial we’re going to see some quick examples on how to make HTTP requests with GraphQL queries using Golang.

Checking for Unchecked Errors within Golang Applications

When it comes to error handling in the Go programming language (Golang), they can either be incredible or a miserable nightmare in terms of management. You can choose to embrace them and check if they are nil every opportunity that you have, or you can ignore them with an underscore. However, what happens in those circumstances where you didn’t even know the function returned something?

Regardless of the story, checking for errors is a good thing, even if you hate doing it. In this tutorial we’re going to see how to scan your code for missed opportunities when it comes to error checking using a nifty open source tool.

TPDP Episode #29: Asynchronous JavaScript Development

The latest episode of The Polyglot Developer Podcast has just published, this time focusing on the use of callbacks, promises, and async / await, in JavaScript.

This episode titled, Asynchronous JavaScript Development, is the twenty-ninth episode to appear on the show and it features Corbin Crutchley, an expert JavaScript developer and open source maintainer.

If you’ve ever struggled with wrapping your head around working with remote resources or blocking tasks in JavaScript, this episode should clear things up.

Moving to Dart from C++

A couple of days ago, while recovering from some flu, I managed to catch up a bit of me reading. If you know anything about the life of an independent contractor, you’d know that there’s never time for your personal projects or hobbies, so this was a most welcome break.

One of my favorite blogs is this one and I saw a great article on Sorting vectors in C++ by Nic Raboy. As it happens, C++ is one of my first commercial languages and I still make some moderate use of it for various mobile projects.

One thing that struck me, as I read the code, was how close this was to the Dart programming language. I’ve been doing a lot of Flutter development of late, and have been making more use of the Dart programming language. Mobile applications often contain complex logic, and this is where Dart has really proven it’s worth to me, in both being a concise and expressive language, but also being familiar enough that I didn’t have to learn everything from scratch to be productive.

In this short tutorial, we’ll take the quicksort algorithm Nic has built in C++ and convert it to Dart. Along the way, we’ll see how close Dart is to C++ and how much of your existing C++ knowledge easily transfers to the Dart environment.

Sort A Vector Of Integers With The Quicksort Algorithm In C++

If you’re studying computer science, at some point you’re going to be exposed to the Quicksort algorithm. Even if you’re not a computer science student, chances are this particular algorithm will come up at some point in time as part of an interview. I’ve been asked about it plenty of times in interview processes and never once used it again.

Whether or not you’ll ever use the Quicksort algorithm, it is important to know and that is what we’re going to review in this back to the basics tutorial.

In this tutorial we’re going to sort a vector of integer values using the Quicksort algorithm. We’re going to use a vector because it is a commonly used data structure in C++.

Getting Familiar With Arrays And Vectors In C++

When it comes to the fundamentals of computer programming, arrays will almost always make an appearance. Being able to store a collection of values could be beneficial to a near endless amount of use-cases.

To continue the back to the basics programming series, in this tutorial we’ll explore standard arrays as well vectors which are a much more powerful alternative when it comes to C++.

Getting Familiar With Loops In C++

In this back to the basics tutorial, we’re going to be exploring loops in C++, something that you’ll take with you well into your software development career, regardless of programming language. The content in this tutorial is targeted at new developers or those that would like to start learning C++.

So when might you want to use a loop? If you need to perform a repetitive task of any kind, a loop is probably going to be want you want to use.

In this tutorial we’re going to explore for loops, while loops, and do-while loops using the C++ programming language.
