Postgresql is my favorite relational database. There are a lot of cool things that Postgresql can do and one of those is to handle the authorization layer. Some people argue that putting authorization logic into the database makes the application code harder to read, and that’s actually true if there is only 1 code base connecting to a database. However, if there are more than 1 code bases communicating with a database, having a centralized authorization logic starts to make more sense. In this blog post, I am not going to discuss the pros and cons of having the authorization logic inside the database, but instead I am going to describe how I put all my authorization logic into postgresql.
I worked with React Native once last year. I was pretty impressed by its ability to apply the same React architecture to build mobile applications. At that time, it was a brief few months working with React Native, so I didn’t have much time playing around with it until recently. For the past 10 days or so I spent most of my spare time learning React Native. And one of the things that I learn is how to have multiple themes for a React Native application. In this blog post, I will describe the basic principles and how I manage multiple themes in my React Native project. This can also be applied to normal React apps since they are just React after all.
Although the game 2048 is not a hot stuff like it used to be several years ago, I am still playing it once in a while. And now I thought that maybe I could try to implement it by myself just to do something else other than web development.
In a project, there usually are a lot of tests. I am not going to discuss how much testing is enough because it depends on each project. What I am going to do in this blog post is to write down what I did for my work project to split a huge mocha test suite into smaller suites and run them in parallel. The end result is a testing process that used to take 7 minutes, now takes around 3 minutes. And the more test suites I run in parallel the faster it becomes.
Although I have been working with React for few years now, the decision between stateless and stateful components is still quite hard for me to make. Stateless components provide a much better and easier to understand flow, while stateful components allow me to develop my application much faster. In this post, I am going to discuss the pros and cons of them and provide my way of writing components that (might) have the best of both worlds (that comes with some drawbacks as well)
In the previous part, I implemented the UI using Vue. In this part, I am going to write about the deployment process using
dokku. This simple chat app is split into 3 separate services
web. Each service can be deployed independently without affecting other running services.
In the previous part, I implemented a simple pub/sub server to push messages to the client side. In this part, I am going to implement the user interface using Vue
In the previous part, I added the basic authentication and authorization to the API service. In this part, I am going to implement the pub/sub messaging service using Faye and integrate it with the API service.
Having a BitTorrent seedbox is convenient in many ways. Few days ago, I needed to download something (totally legal!) using BitTorrent, but I don’t want to open my laptop 24/7 for seeding. Since I already have a dokku server up and running, I can just set up a BitTorrent seedbox using rtorrent and ruTorrent
In my current project, I need to grab data from youtube gaming pages. I have done similar thing previously, but with the normal youtube channel pages. The new gaming pages are rendered in a completely different way. It took me some digging around the source code to finally be able to figure out a way to extract data. This blog post summarizes what I have done to get the data out of a youtube gaming channel page.
