I'm not open-sourcing very often anymore, but recently I finished developing a small tool called q2m that I believe is worth sharing. It's a library designed to convert URL parameters into MongoDB queries, which I needed for my latest project, a little SaaS called Lumina CMS.

Back in February last year I blog on topic Email not working after DNS change. Well, I had kinda similar situation but not exactly. This time I bought a domain from Google and wanted to use an email with it. The setup wasn't obvious for me so I decided to document the process.

The router is the backbone of your application. Trust me, that's how it is and I can prove it. One of the fundamental ideas in Web is the URL (Uniform Resource Locator). Or the way of how we very often call it - "web address". No mather what you are building there is a web address which identifies your resource. The router is the front office that accepts the request to particular URL and wires it to a logic. Logic for generating HTML or JSON response or something else. So, the router is very important part of your system.

At the end of last year I rewrote one of my favorite projects - a vanilla JS router called Navigo. I was procrastinating this work for years. Finally I did it in TypeScript and wrote 100+ unit tests along the way. This refactoring opens the door for new features and more importantly, for integrating the library into other places. Like React for example.

Last weekend I was helping a friend to deal with his "broken" iPhone XR. It was stuck on the Apple logo. No mather what we do the phone was just black and the apple shows up.

Just recently I had to do changes in Google Tag Manager at work. It's interesting how I keep forgetting how everything works. So I finally decided to sit down and write an article about these things. If nothing else I will have a good memory snapshot to remind me what is what.

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.

I just recently moved my outset.ws domain to Zeit name servers. That's my 13 years old domain which I'm not using it anymore. It makes sense to point to krasimirtsonev.com. The thing is that I have an email which is used all over the net. I of course want to keep that email. And suddenly I wasn't able to receive messages to it. I started missing some very important emails. Like bills that have to be paid and GitHub notifications.

CSP is a formal language for describing patterns of interaction in concurrent systems. It's used in Go, Crystal, Clojure's core.async and a couple of other places. The idea in its core is nothing so complicated but it offers some interesting capabilities. Surprisingly enough it is not really popular in JavaScript. Recently I'm exploring this pattern and here are my findings.

Riew is a library based on communicating sequential processes (CSP). It is made to help with communication and synchronization between your view and business logic. It's distributed as a npm package, it has 0 dependencies and adds ~8KBs (gzip) to your application on production.

In this article we will see some use cases of Riew. Those are patterns which I found repeating while using the library. There are other blog posts part of the same series and I will suggest checking at least this one so you get a basic understanding before jumping into the code snippets below.

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.

Тази седмица мои гости бяха Мишо и Найден от Nerds2Nerds. Както всеки път така и в този епизод темите са малко на случаен принцип. Поговорихме си за интервю процеси, за remote work и къде е по-яко да се работи.

One of my favorite conferences Bulgaria Web Summit 2017 is just around the corner. I’m happy to attend again. The organizer prepared a good set of speakers and the event is two days this year.

I’m writing code for approximately ten years now and at some point the word “writing” became more important then “code”. I found out that it is easy to generate code but it is difficult to write code. Writing means creating something meaningful. Something that other human beings will read. The code is indeed sent to machines and they do understand ugly code. Not the same for humans though. An important part of our job is to make sure that our code is clear for other teammates.

If you build single page applications you probably know that one of the must-have parts is the router. The bit that knows how to tweak the content of the address bar and notifies the rest of the system for URL changes. In this article we will discuss the various aspects of the routing in the browser.

This is a quick post so I document my two hours research. I'm working on a open source library for routing in the browser. Or in other words JavaScript library that uses the history API. The thing is that locally I'm using Apache as a dev server and I wanted all the request to specific folder to be redirected to index.html.

(The router here is now placed in its own project - Navigo. There is also another article Deep dive into client-side routing which you may find interesting)

Nowadays the popular single page applications are everywhere. Having such application means that you need a solid routing mechanism. Frameworks like Emberjs are truly build on top of a Router class. I'm still not sure that this is a concept which I like, but I'm absolutely sure that AbsurdJS should have a build-in Router. And, as with everything in this little library, it should be small, simple class. Let's see how such a module may look like.

There are few things which I'm thinking about last few months. I summarize them here. Initially, I started writing this article for the company which I'm working for - East Interactive. The material is not meant to teach. It just contains few thoughts of main and I hope that my colleagues will find it helpful.

In this article I want to share my thoughts regarding responsive design. I made several talks on this subject and this post is some kind of summary. The article presents concepts like mobile first and design in the browser.

Everyday I'm reading or watching something which I find helpful. Normally I bookmark those things, but at the end I have dozen of folders and subfolders which I never check. So, I decided to make such blog post where I'll share valuable things in the net.

PHP is one of the most popular back-end solutions available. However, I think that there is something wrong with the way we are using it. It is really popular to use some giant framework, with a lot of features. Generally, I'm not a big fan of this approach. Even if the framework is well documented and has big community it still adds some restrictions and complexity. Many people are trying to build the perfect framework, which covers as many cases as possible, but the true is that it is not possible. In this article I'll present you my vision about PHP programming and I will be very happy if you share yours.

For some time, I bring a lot of attention to the tests of everything that I'm working on. Actually Test Driven Development changed a lot my vision for programming. Dale Emery shares really interesting thoughts regarding automated testing. Checkout here.

When we are talking about maps, Google is an absolute leader. Their GoogleMaps tool is free, well documented and works really good. What I didn't find directly in the documentation is how to get the exact location based on plain text. I.e. to convert an address to google.maps.LatLng object. That's why I wrote a simple function that did this job.

Интересни коментари събрани от Иво Илиев (оригинален текст):001. Чудесно! Точно така си го представях… само че малко по-различно.002. Вчера с комшията говорихме и ми даде страхотна идея. Виж ся как ше стане дизайна…003. Имам само една, две леки забележки. Имаш ли полвин час да ги изкоментираме?004. Добре е , но неможеш ли малко да го поразчупиш?005. Искам го 1:1 с това, но да е малко по-различно.

Yesterday I received host name, user name and password for a MySQL server. I needed to export the data from it. I didn't have access to PHPMyAdmin, I tried to connect to the server by mysql.exe on my PC, but it didn't work. And then I found really good solution - PHPMyAdmin in only one php file. I launched it from my localhost and it works. So if you need to export data or just see it, use Adminer. I also uploaded the file on my server, you can download it from here.

Google offers a lot of free tools for us. One of them is really useful and easy to work with - GoogleMaps API. In this article I will show you how to import a map in Flash and place an icon in a specific place.
