From PHP to Node with Zeit's lambdas and Cypress.io

The first post in this blog was published on 25th of August 2008. This place was always living on a shared PHP/MySQL hosting. It was driven by a custom made PHP CMS for over 10 years. It is time to move forward and follow my actual language of choice - JavaScript. I spent some time recently migrating it to Zeit and this article is showing my process.

Reactive view - the concept

Something bugs me last couple of years. I'm using React for some time now and there is always this doubt if I'm placing the business logic on the right place. I'm trying to be pragmatic, to follow best practices and listen what the community is saying. However, I still feel that something is not ok. This blog post presents the idea of the reactive view. That is nothing new per se but I came up with this term because it fits well in my idea.

Hopa - zero config CLI that runs JavaScript and TypeScript

Yesterday was one of those days. I stumbled a task and wanted to find the right tool for it. That same task is on my way at least twice a week and I always refuse to optimize it. Because it was a weekend I decided to spend some time and research a proper tool for the job. Well, I find nothing that suites my need. I time-boxed a hour and said F.ck it!. I will code it myself. That's how Hopa was born - a zero config CLI that runs JavaScript and TypeScript. Transpiles, bundles, watches and executes code.

Octomments - using GitHub as a comment plugin

87% of my readers are using Chrome on desktop. This means that I have the luxury to care less about performance. However I just recently found that this blog has 56 (out of 100) points on Google's pagespeed test. That's not good. The report says that my Disqus comments are blocking the main thread for ~900ms. I want comments on my blog but I also want my users to reach to content as quickly as possible. So, after so many years using Disqus I decided to break with it and use something else.

From 0 to 100 GitHub stars in a week

2020 for me started with the release of several OS projects. Two of them reached 100 stars in a week and I was thinking that would be nice sharing my workflow. Not like it is working every time, absolutely not, but leads to some good results.

Pairify - how to match balanced string pairs

I'm now actively working on a VSCode extension. I started it as a theme but then decided to add some more features. Like for example a tin line on the left side of the editor marking the current function scope. In order to do that I had to analyze the current file's code and find the lines that are included in that scope. The obvious approach will be to translate the code to AST and then traverse the tree finding the information that I need. This however will require the usage of a language server which now I don't want to deal with. So I decided to explore a brute force approach. Looping over the string characters and finding balanced matches. I quickly wrapped it into a library. I called it Pairify. It consumes text and returns an array of pairs. This blog post will show you how it works.

NADCAST.24 с Радо Станков

В тези смутни времена се чуваме online с Радо Станков за да си поговорим за remote working. Не че по принцип не се чуваме така, но сега е малко по-различно. В този 24-ти епизод споделяме нашия опит в работа от разстояние. Приятно слушане.

Create your own Covid-19 data tracker

I'm continuing to experiment with React and TypeScript. The weekend-long project this time was a Covid-19 data tracker. In this blog post I will share how I built c19stats.now.sh. I exposed the data as a public API at the same URL. I guess you, as many other people, follow the situation so you may want to glue your fingers on the keyboard and create something useful around the data. I got lots of fun playing with the diagrams.

Smart placeholders in your markdown

I ❤️ markdown. I like its simplicity and minimalistic API which is good enough to cover most of needed HTML markup. At least for textual content. At work we have a small node based microservice that delivers data from Contentful in exactly markdown format. It's all working well but we started having cases where part of the text is in Contentful and the other part is in that microservice. For example when we have a button with a catchy design. We want to content manage the label of the button but the actual markup to be on our side.
