Weblog on Dmitry Sheiko's Web Development Blog

Over the past year I migrated several legacy projects to Next.js with the help of Claude Code.

GoF design patterns gave OOP developers a shared vocabulary for recurring structural problems.

It probably started when I was very young.

As a web developer, you can start using Claude Code in VS Code almost immediately after installing the extension.

Software can be perfectly functional, secure, and even performant, yet still become a long-term problem.

Web Push notifications have quietly become one of the most effective engagement channels on the web.

Implementing a custom 404 page in Next.js versions <=16 can be surprisingly tricky when using route groups.

When developing administrative UIs, one of the most common patterns is a table to navigate database records and modals to view or edit individual entries.

E2E tests are easy to write and hard to keep fast and reliable.

At the beginning of 2025, Next.js is likely the best choice for React developers building server-side applications.

When React Hooks arrived in 2019, migrating a large class-based codebase to functional components looked impractical.

This blog hadn’t a redesign for a decade.

Nowadays nobody would argue the importance of automated testing.

Images in HTML, what could be easier?

Functional testing is nothing new.

Eventually Puppetry 2.0 was released.

In software engineering we try to discover and eliminate bugs as soon as possible.

A sound application architecture doesn’t resist to changes, but welcomes them.

When we talk about user input within a web app we often think first of HTML forms.

I’ve been working with PHP since 2000 and with JavaScript even longer.

I observe as some people still write ancient ES5 syntax of JavaScript and it’s disheartening.

What do you do when you need a widget-like functionality?

Before modules Historically JavaScript had neither a module system, nor facilities to load sources from within the code.

I always fancied to write a book that would combine most of my programming experience gathered over two decades.

I’ve been working with Backbone for years and it suited me pretty well.

As developers we spend a lot of our time on debugging and particularly on spotting the source of a problem.

Modern application get complex, we cannot go without automated testing.

Nowadays JavaScript evolves fast.

My book “Unlocked JavaScript” (https://www.packtpub.com/web-development/javascript-unlocked) has been released on December 7, 2015.

User are impatient.

We write unit-tests tests for server-side source code and for JavaScript.

Modules in JavaScript With the advance of MV* frameworks you can observe as JavaScript evolves ahead of official specs towards large scale development.

CSS may look as a simple language.

It seems like these days the most trending concept in the HTML5 world is web components.

What we are going to do is a modal window that opens in the center of the screen by pressing a link while everything that underlies the window becomes blurred.

JavaScript frameworks have been proliferating recently with a frightening rate.

In spite of most server-side languages JavaScript was not designed for templates.

JavaScript was designed as a script language that is easy to embed in a larger host system and meant to manipulate the objects of the host system.

Bobby Solomon, from the Disney team, said in 2012: “Honestly, our team is bored of talking about responsive design.

We all are taught not to repeat ourselves while coding.

As JavaScript application grows, navigation on the code becomes a hell.

Since the very beginning of HTML there were no much of changes regarding forms until recently.

Reasonably statistic analyses belong to CMS ACP reports.

Back in 2013, AMD was the standard approach for non-blocking script loading.

On the way to harmony Not so long ago Microsoft announced a new language targeting front-end developers.

Recently I’ve laid my hands on a copy of [“PHP Application Development with NetBeans” by M A Hossain Tonu](http://www.amazon.com/gp/product/1849515808 ““PHP Application Development with NetBeans” by M A Hossain Tonu”) (www.PacktPub.com).

Making design responsive means not only certain representations on different screens, but also particular behavior on different devices.

A few months ago I bought a new Macbook.

After Microsoft released TypeScript I took a look at their examples and found the idea pretty promising.

Back in 1995 Netscape wanted a language with a simple programming model, but flexible enough for building real scalable applications.
