12.3.2019
Chcete se snadno dostat na policejní služebnu? Zajeďte si do Japonska a do veřejného webového fóra pošlete odkaz na stránku s primitivním javascritpem, který v nekonečné smyčce otevírá dialog.
Přesně to se totiž stalo na počátku března třináctileté školačce, která za relativně neškodný
Get Started with Node: An Introduction to APIs, HTTP and ES6+ JavaScript
11.3.2019
Jamie Corkhill has written this wonderful post about Node and I think it’s perhaps one of the best technical articles I’ve ever read.

The Client/Server Rendering Spectrum
6.3.2019
I've definitely been guilty of thinking about rendering on the web as a two-horse race. There is Server-Side Rendering (SSR, like this WordPress site is doing) and Client-Side Rendering (CSR, like a typical React app). Both are full of advantages and disadvantages. But, of course, the conversation...

The Bottleneck of the Web
5.3.2019
Steve Souders, "JavaScript Dominates Browser CPU":
Ten years ago the network was the main bottleneck. Today, the main bottleneck is JavaScript. The amount of JavaScript on pages is growing rapidly (nearly 5x in the last 7 years). In order to keep pages rendering and feeling fast, we need to focus...
Why I Write CSS in JavaScript
5.3.2019
I'm never going to tell you that writing your CSS in CSS (or some syntactic preprocessor) is a bad idea. I think you can be perfectly productive and performant without any tooling at all. But, I also think writing CSS in JavaScript is a good idea for component-based styles in codebases that build...

Should I Use Source Maps in Production?
1.3.2019
It's a valid question. A "source map" is a special file that connects a minified/uglified version of an asset (CSS or JavaScript) to the original authored version. Say you've got a filed called _header.scss that gets imported into global.scss which is compiled to global.css. That final CSS file...
Why CSS Needs its Own Survey
1.3.2019
2016 was only three years ago, but that’s almost a whole other era in web development terms. The JavaScript landscape was in turmoil, with up-and-comer React — as well as a little-known framework called Vue — fighting to dethrone Angular.
Like many other developers, I felt lost. I needed some...

JavaScript Proxy

I love the idea of programmatically generated images. That power is close at hand these days for us front-end developers, thanks to the concept of headless browsers. Take Puppeteer, the library for controlling headless Chrome. Generating images from URLs is their default use case:
