Over the last weekend, I took a look at a web app built by some folk. It uses JWT and the first thing I usually test whenever I come across apps like this is to check if there is a revocation strategy for these tokens. Basically JWTs generally rely on client expiration and will always be considered valid until it...

A topic that keeps on coming up in r/reddit is How do I solve database migrations in Go ? Most people including myself came from other languages such as PHP and Ruby where database migrations are a problem that have been solved. Rails from the Ruby world and Laravel from the PHP world as an example. But how do I...

I have been using Jekyll, Github pages plus Cloudflare to host my blog for a while now. A simple push to my Github repo (adelowo.github.io) === a deployment of my Jekyll site. They’d build it and deploy it automatically. For me, there was no infrastructure overhead. While that is great, I wanted to have full control over the servers and...

In the modern day cloud, applications or services ( if you will ) are usually distributed across a cluster of machines and with comes multiple IP addresses and port numbers that would be extremely hard to remember, especially given the fact that most software this days end up having dynamic IPs. Tearing down and restarting the same service most likely...

I am currently working on a project that was originally a proof of concept i.e I am now to convert it to a real application. In it’s original form, it lacked tests, so I figured out that would be the first place I start from while refactoring and adding newer features. While I was writing integration tests for mysql, I...

In the last 2 months I have stored configuration details in multiple ways and this post is a reflection of those methods and what I default to now - I have seen the light. As a developer trying to improve and follow well known best practices. The 12 factor app is usually where you would want to go to when...

Random thoughts Go as a language interests me a lot and interfaces are one big part of it. And when I say interfaces, I am talking about the design - satisfied implicitly rather than explicitly -, extremely tied to behaviour. If you have ever spent some time writing Go code, one thing you would have noticed is the extensive presence...

As a self taught developer, I am always looking out for ways to improve my software dev kit and knowledge. A big part of any developer dev kit is an editor. My editor of choice has always been anything made by Jetbrains. I used to make use of PHPStorm - well that’s the only sane IDE for PHP development. I...

I have written quite a bit on HTTP. And this blog post is just yet another one that talks about another interesting concept in the way Go deals with HTTP and how it makes HTTP related stuffs even much more fun. In this post, I would be covering what Round tripping is, it’s applicable usecases and a tiny demo that...

We write code all the time and managing tight coupling is a challenge we actively face. This post attempts to address and show a practical example of separating our concerns(business logic) and the database. While this post describes this process via a database, note that it can be applied to any other part of the codebase. PS, mocking 101, Coming...

Testing is a subject extremely close to my heart. I talk (write) about it all the time and one of the reasons I fell in love with Go was the simplicity of the testing standard library alongside it’s ease of usage. But simplicity is actually complicated. With simple and tiny test suites (e.g the universally accepted calculator example), the standard...

When writing tests in Go, there are two options as per how you choose to name your package’s tests; package foo or package foo_test. While both are perfectly valid and idiomatic, it leaves the question of which do we use ?. With package foo_test, what you are essentially getting is a black box system. You only run your tests against...
