JavaScript Proxy
26.2.2019
I’ve always loved the flexibility of Objects and prototypes in JavaScript, but for a long time, I felt that a level of dynamism was lacking. JavaScript eventually added get and set methods for object properties, which was an awesome step, but there was still room for improvement....

Getting to Grips with the Airtable API
14.2.2019
The Airtable web app is pretty neat. You can use it like a spreadsheet but it’s useful for all sorts of other things too. The neatest thing about it for me is that it has an API so that you can treat it like a database.
I’ve been thinking about making weekly notes for the different teams I work...
Avoiding those dang cannot read property of undefined errors
13.2.2019
Uncaught TypeError: Cannot read property 'foo' of undefined. The dreaded error we all hit at some point in JavaScript development. Could be an empty state from an API that returns differently than you expected. Could be something else. We don’t know because the error itself is so general...
React’s Experimental Suspense API Will Rock for Fallback UI During Data Fetches
2.2.2019
Most web applications built today receive data from an API. When fetching that data, we have to take certain situations into consideration where the data might not have been received. Perhaps it was a lost connection. Maybe it was the endpoint was changed. Who knows. Whatever the issue, it's...
Představení PSD2 nejen pro vývojáře. Blíží se otevřené bankovnictví? Udělejte si v tom jasno.
29.1.2019
Ačkoliv mi připadá, že články o PSD2 se to všude jen hemží, překvapuje mě, že spousta mých známých má problém se v současné situaci vyznat. Naopak mají pocit, že s další novou informací mají o PSD2 větší nejasnost. Pokusím se to tímto textem změnit
Need to Test API Endpoints? Two Quick Ways to Do It.
25.1.2019
Here's a possibility! Perhaps you are testing your JavaScript with a framework like Jasmine. That's nice because you can write lots of tests to cover your application, get a nice little UI to see the output, and even integrate it with build and deploy tools to make your ongoing development work...

Amazing User Agent API with userstack
17.1.2019
We do our best to design and code websites so that they look and perform the way they should regardless of device or browser, but the truth is we sometimes we need to code for specific device, browser, or crawler. Whether it’s a quick hack or a simply wanting to display different content...
How I Built a GPS-Powered Weather Clock With My Old iPhone 4
17.1.2019
My first smartphone was an iPhone 4s. I remember the excitement of exploring its capabilities at a time when it was the coolest thing around. Eventually, of course, I replaced it with a newer model and the old iPhone, still in mint condition, gathered dust for two years. What a waste!
But was...

Gradient Borders in CSS
28.12.2018
Let's say you need a gradient border around an element. My mind goes like this:
There is no simple obvious CSS API for this.
I'll just make a wrapper element with a linear-gradient background, then an inner element will block out most of that background, except a thin line of padding around...

The Fragmented, But Evolving State of CSS-in-JS

TLDR: The CSS-in-JS community has converged on a consistent API.
Not so long ago, a Facebook engineer compiled a list of the available CSS-in-JS methodologies. It wasn’t short:

Two Ways to Build a Site That Seem Super Different But Weirdly Aren’t That Different
14.12.2018
Here are two ways to build a site (abstractly) that feel diametrically opposed to me:
Build a site as an SPA (Single Page App). The page loads a skeleton HTML page that executes JavaScript as quickly as it can. The JavaScript calls an API to get data, and then the page renders content. Navigation...
