We use ad-blockers as well, you know. We gotta keep those servers running though. Did you know that we publish useful books and run friendly conferences — crafted for pros like yourself? E.g. upcoming SmashingConf Barcelona, dedicated to smart front-end techniques and design patterns.
I’m sure you’ve heard the proverb, “A chain is only as strong as its weakest link,” probably many times. Its written origin dates back to the 18th century, but I wouldn’t be surprised if it was much, much older. And though the work we do has little to do with actual chains, this proverb is every bit as relevant to us.
Remember when Azer Koçulu unpublished more than 250 of his modules from npm (Node Package Manager)? If that name doesn’t ring a bell, perhaps this function name will:
left-pad. In case you’re still scratching your head wondering what the heck I’m talking about, Azer removed a bunch of functions from the canonical library of reusable Node.js code and, in doing so, brought thousands of projects to their knees, including high-profile ones like Babel and React.
In part 1 of this tutorial we started building our iOS app from scratch. We started out by setting up a blank React Native project. Then we pulled data from the Unsplash.it API. Because downloading data takes time, we built a loading screen.
In the process we went over positioning UI elements with flexbox and styling them using CSS-like properties. Towards the end of part 1 we downloaded and included a third-party
Swiper component from GitHub, which allowed us to display wallpaper data in a swipeable container.

You know how it works: you spend hours trying to find a workaround for a problem that you have encountered, just to realize that it doesn't quite work in, you know, that browser. Finding little techniques and tricks to help you get to results faster can immensely improve your productivity, so you don't have to waste time on solutions that will never see the light of day.
I love finding those little useful front-end goodies that make our lives easier. Since technologies emerge and evolve permanently, keeping track on what's going on is often difficult, especially since specifications change and so does the browser support. For a replacement talk at SmashingConf Oxford last week, I've decided to collect some of the useful techniques from various articles, conversations and my workshops in a slide deck — and since it proved to be useful for many front-end developers I've spoken to after the talk, I'm very privileged to share it with the entire community as well.Read more...
Preload (spec) is a new web standard aimed at improving performance and providing more granular loading control to web developers. It gives developers the ability to define custom loading logic without suffering the performance penalty that script-based resource loaders incur.
A few weeks ago, I shipped preload support in Chrome Canary, and barring unexpected bugs it will hit Chrome stable in mid-April. But what is that preload thing? What does it do? And how can it help you?Read more...
Augmented reality is generally considered to be very hard to create. However, it's possible to make visually impressive projects using just open source libraries. In this tutorial we'll make use of OpenCV in Python to detect circle-shaped objects in a webcam stream and replace them with 3D Earth in Three.js in a browser window while using WebSockets to join this all together.
We want to strictly separate front-end and back-end in order to make it reusable. In a real-world application we could write the front-end in Unity, Unreal Engine or Blender, for example, to make it look really nice. The browser front-end is the easiest to implement and should work on nearly every possible configuration.Read more...
The Internet of Things (IoT) has enabled the Internet to reach beyond the browser. Made up of electronically networked devices, these “things” are able to interact with the physical world via sensors that feed data they capture back into their ecosystems.
Currently, these devices are mostly products, designed with a specific purpose in mind, a typical example being a fitness band that tracks activity. It reports the information gathered to an app, which is then able to analyze the data and offer suggestions and motivation to push the user further.Read more...
Sam Loyd (1841–1911), American chess player and puzzle maker, created the sliding tiles puzzle in the 1870s. The puzzle is represented by an m×n grid, where m is number of columns and n is number of rows, and each cell can be any imaginable value (number, letter, image, and so on.)
The purpose of the puzzle is to rearrange the initial configuration of the tiles to match another configuration known as the goal configuration. The rearrangement task is achieved by swapping the empty tile with some other tile in all possible directions (up, down, left, and right).Read more...
