Refactoring our simple Twitter API project to use concurrency and modules
In my last article, I showed you a simple Twitter script to connect to the API and clean some data. That script, was horrible, as all the code resided in a single .go file and […]
Querying the Twitter API in Golang and cleaning up the response
In this post, I am going to show you how to query the Twitter API in Golang and tidy up the response output. Note that this code includes no go routines or channels for concurrency […]
Golang: Go-routines and channels
Typically, if we ran a loop through a number of items, they happen serially (one after the other). But, something cool about Golang is the ability to run Go Routines. We have the main routine […]
Golang: the HTTP module for get requests
Making HTTP requests in Golang is pretty simple, I’ve included a code sample below. Within the main function we define two new variables (resp and err). The HTTP get function returns the response; which is […]
Golang: everything you need to know about maps
Maps are pretty similar to dictionaries in Python. In the below, I define a map called red_paints. In this map, I detail the name of the specific red colours for a few companies. When we […]
Golang: Writing test cases in Go
In this article, we’re going to look at how we write test cases in Golang. Here, I will create a file called acct_test.go; which can be run by simply typing go test into the terminal. […]
Golang: Getting to the Pointers
Golang uses memory management for our variables so updating values in our structs as we defined in the previous article, doesn’t necessarily work as we expected. Let’s say we have the below, this piece of […]
Golang: Getting started with structs
A struct is a data type in Golang, it can also be compared to a class in an object oriented programming language. A struct gives us the ability to set specific fields for a type […]
Golang: Reading and writing files
Reading and writing files is a key part of most applications. In Golang, it’s not quite as straightforward as with other languages like Python, but let’s go through it line by line to understand how […]
Golang: Getting started with If statements
If statements in Golang are pretty simple, so this is going to be a really short article. What I would like to do, is compare the same if statements in Python and Golang to give […]
Golang: Multiple return values from functions
Okay, so in this article, we’re going to talk about a few things. We’re going to look at how we return multiple values from a function; within that function we’re also going to take subsets […]
