| 201 | 201 | Lint the Web Forward With Sonarwhal | Years ago, when I was in a senior in college, much of my web development courses focused on two things: the basics like HTML and CSS (and boy, do I mean basic), and Adobe Flash. I spent many nights writing ActionScript 3.0 to build interactions for the websites that I would add to my portfolio. A few months after graduating, I built one website in Flash for a client, then never again. Flash was dying, and it became obsolete in my résumé and portfolio. That was my first lesson in the speed at which things change in technology, and what a daunting realization that was as a new graduate looking to enter the professional world. Now, seven years later, I work on the Microsoft Edge team where I help design and build a tool that would have lessened my early career anxieties: sonarwhal. Sonarwhal is a linting tool, built by and for the web community. The code is open source and lives under the JS Foundation. It helps web developers and designers like me keep up with the constant change in technology while simultaneously teaching how to code better websites. Introducing sonarwhal’s mascot Nellie Good web development is hard. It is more than HTML, CSS, and JavaScript: developers are expected to have a grasp of accessibility, performance, security, emerging standards, and more, all while refreshing this knowledge every few months as the web evolves. It’s a lot to keep track of. Web development is hard Staying up-to-date on all this knowledge is one of the driving forces for developing this scanning tool. Whether you are just starting out, are a student, or you have over a decade of experience, the sonarwhal team wants to help you build better websites for all browsers. Currently sonarwhal checks for best practices in five categories: Accessibility, Interoperability, Performance, PWAs, and Security. Each check is called a “rule”. You can configure them and even create your own rules if you need to follow some specific guidelines for your project (e.g. validate analytics attributes, title format of pages, etc.).

| 202 | 202 | Design Systems and CSS Grid | Recently, my client has been looking at creating a few new marketing pages for their website. They currently have a design system in place but they’re looking to push this forward into 2018 with some small and possibly some larger changes. To start with we are creating a couple of new marketing pages. As well as making use of existing components within the design systems component library there are a couple of new components. Looking at the first couple of sketch files I felt this would be a great opportunity to use CSS Grid, to me the newer components need to be laid out on that page and grid would help with this perfectly. As well as this layout of the new components and the text within it, imagery would be used that breaks out of the grid and pushes itself into the spaces where the text is aligned. The existing grid system When the site was rebuilt in 2015 the team decided to make use of Sass and Susy, a “lightweight grid-layout engine using Sass”. It was built separating the grid system from the components that would be laid out on the page with a container, a row, an optional column, and a block. To make use of the grid system on a page for a component that would take the full width of the row you would have to write something like this: <div class="grid-container"> <div class="grid-row"> <div class="grid-column-4"> <div class="grid-block"> <!-- component code here --> </div> </div> </div> </div> Using a grid system similar to this can easily create quite the tag soup. It could fill the HTML full of divs that may become complex to understand and difficult to edit. Although there is this reliance on several <div>s to lay out the components on a page it does allow a tidy way to place the component code within that page. It abstracts the layout of the page to its own code, its own system, so the components can ‘fit’ where needed. The requirements of the new grid system Moving forward I set myself some goals for what I’d like to have achieved in this new grid system: It needs to… | 2017 | Stuart Robson | stuartrobson | 2017-12-12T00:00:00+00:00 | https://24ways.org/2017/design-systems-and-css-grid/ | code |
| 203 | 203 | Jobs-to-Be-Done in Your UX Toolbox | Part 1: What is JTBD? The concept of a “job” in “Jobs-To-Be-Done” is neatly encapsulated by a oft-quoted line from Theodore Levitt: “People want a quarter-inch hole, not a quarter inch drill”. Even so, Don Norman pointed out that perhaps Levitt “stopped too soon” at what the real customer goal might be. In the “The Design of Everyday Things”, he wrote: “Levitt’s example of the drill implying that the goal is really a hole is only partially correct, however. When people go to a store to buy a drill, that is not their real goal. But why would anyone want a quarter-inch hole? Clearly that is an intermediate goal. Perhaps they wanted to hang shelves on the wall. Levitt stopped too soon. Once you realize that they don’t really want the drill, you realize that perhaps they don’t really want the hole, either: they want to install their bookshelves. Why not develop methods that don’t require holes? Or perhaps books that don’t require bookshelves.” In other words, a “job” in JTBD lingo is a way to express a user need or provide a customer-centric problem frame that’s independent of a solution. As Tony Ulwick says: “A job is stable, it doesn’t change over time.” An example of a job is “tiding you over from breakfast to lunch.” You could hire a donut, a flapjack or a banana for that mid-morning snack—whatever does the job. If you can arrive at a clearly identified primary job (and likely some secondary ones too), you can be more creative in how you come up with an effective solution while keeping the customer problem in focus. The team at Intercom wrote a book on their application of JTBD. In it, Des Traynor cleverly characterised how JTBD provides a different way to think about solutions that compete for the same job: “Economy travel and business travel are both capable candidates applying for [the job: Get me face-to-face with my colleague in San Francisco], though they’re looking for significantly different salaries.

| 204 | 204 | Cascading Web Design with Feature Queries | Feature queries, also known as the @supports rule, were introduced as an extension to the CSS2 as part of the CSS Conditional Rules Module Level 3, which was first published as a working draft in 2011. It is a conditional group rule that tests if the browser’s user agent supports CSS property:value pairs, and arbitrary conjunctions (and), disjunctions (or), and negations (not) of them. The motivation behind this feature was to allow authors to write styles using new features when they were supported but degrade gracefully in browsers where they are not. Even though the nature of CSS already allows for graceful degradation, for example, by ignoring unsupported properties or values without disrupting other styles in the stylesheet, sometimes we need a bit more than that. CSS is ultimately a holistic technology, in that, even though you can use properties in isolation, the full power of CSS shines through when used in combination. This is especially evident when it comes to building web layouts. Having native feature detection in CSS makes it much more convenient to build with cutting-edge CSS for the latest browsers while supporting older browsers at the same time. Browser support Opera first implemented feature queries in November 2012, both Chrome and Firefox had it since May 2013. There have been several articles about feature queries written over the years, however, it seems that awareness of its broad support isn’t that well-known. Much of the earlier coverage on feature queries was not written in English, and perhaps that was a limiting factor. @supports ― CSSのFeature Queries by Masataka Yakura, August 8 2012 Native CSS Feature Detection via the @supports Rule by Chris Mills, December 21 2012 CSS @supports by David Walsh, April 3 2013 Responsive typography with CSS Feature Queries by Aral Balkan, April 9 2013 How to use the @supports rule in your CSS by Lea Verou, January 31 2014 CSS Feature Queries by Amit Tal, June 2 2014 Coming Soon: CSS Feature Queries by Adobe Web Platform Team, August 21 2014 CSS featu… | 2017 | Chen Hui Jing | chenhuijing | 2017-12-01T00:00:00+00:00 | https://24ways.org/2017/cascading-web-design/ | code |
| 205 | 205 | Why Design Systems Fail | Design systems are so hot right now, and for good reason. They promote a modular approach to building a product, and ensure organizational unity and stability via reusable code snippets and utility styles. They make prototyping a breeze, and provide a common language for both designers and developers. A design system is a culmination of several individual components, which can include any or all of the following (and more): Style guide or visual pattern library Design tooling (e.g. Sketch Library) Component library (where the components live in code) Code usage guidelines and documentation Design usage documentation Voice and tone guideline Animation language guideline Design systems are standalone (internal or external) products, and have proven to be very effective means of design-driven development. However, in order for a design system to succeed, everyone needs to get on board. I’d like to go over a few considerations to ensure design system success and what could hinder that success. Organizational Support Put simply, any product, including internal products, needs support. Something as cross-functional as a design system, which spans every vertical project team, needs support from the top and bottom levels of your organization. What I mean by that is that there needs to be top-level support from project managers up through VP’s to see the value of a design system, to provide resources for its implementation, and advocate for its use company-wide. This is especially important in companies where such systems are being put in place on top of existing, crufty codebases, because it may mean there needs to be some time and effort put in the calendar for refactoring work. Support from the bottom-up means that designers and engineers of all levels also need to support this system and feel responsibility for it. A design system is an organization’s product, and everyone should feel confident contributing to it. If your design system supports external clients as well (such as contractors), they too can become val… | 2017 | Una Kravets | unakravets | 2017-12-14T00:00:00+00:00 | https://24ways.org/2017/why-design-systems-fail/ | process |
| 206 | 206 | Getting Hardboiled with CSS Custom Properties | Custom Properties are a fabulous new feature of CSS and have widespread support in contemporary browsers. But how do we handle browsers without support for CSS Custom Properties? Do we wait until those browsers are lying dead in a ditch before we use them? Do we tool up and prop up our CSS using a post-processor? Or do we get tough? Do we get hardboiled? Previously only pre-processing tools like LESS and Sass enabled developers to use variables in their stylesheets, but now Custom Properties have brought variables natively to CSS. How do you write a custom property? It’s hardly a mystery. Simply add two dashes to the start of a style rule. Like this: --color-text-default : black; If you’re more the underscore type, try this: --color_text_default : black; Hyphens or underscores are allowed in property names, but don’t be a chump and try to use spaces. Custom property names are also case-sensitive, so --color-text-default and --Color_Text_Default are two distinct properties. To use a custom property in your style rules, var() tells a browser to retrieve the value of a property. In the next example, the browser retrieves the black colour from the color-text-default variable and applies it to the body element: body { color : var(--color-text-default); } Like variables in LESS or Sass, CSS Custom Properties mean you don’t have to be a dumb mug and repeat colour, font, or size values multiple times in your stylesheets. Unlike a preprocessor variable though, CSS Custom Properties use the cascade, can be modified by media queries and other state changes, and can also be manipulated by Javascript. (Serg Hospodarets wrote a fabulous primer on CSS Custom Properties where he dives deeper into the code and possible applications.) Browser support Now it’s about this time that people normally mention browser support. So what about support for CSS Custom Properties? Current versions of Chrome, Edge, Firefox, Opera, and Safari are all good. Internet Explorer 11 and before? Opera Mini? Nasty. Sound familiar?

| 207 | 207 | Want to Break Out of Comparison Syndrome? Do a Media Detox | “Comparison is the thief of joy.” —Theodore Roosevelt I grew up in an environment of perpetual creativity and inventiveness. My father Dennis built and flew experimental aircraft as a hobby. During my entire childhood, there was an airplane fuselage in the garage instead of a car. My mother Deloria was a self-taught master artisan who could quickly acquire any skills that it took to work with fabric and weaving. She could sew any garment she desired, and was able to weave intricate wall hangings just by looking at a black and white photos in magazines. My older sister Diane blossomed into a consummate fine artist who drew portraits with uncanny likeness, painted murals, and studied art and architecture. In addition, she loved good food and had a genius for cooking and baking, which converged in her creating remarkable art pieces out of cake that were incredibly delicious to boot. Yes. This was the household in which I grew up. While there were countless positives to being surrounded by people who were compelled to create, there was also a downside to it. I incessantly compared myself to my parents and older sister and always found myself lacking. It wasn’t a fair comparison, but tell that to a sensitive kid who wanted to fit in to her family by being creative as well. From my early years throughout my teens, I convinced myself that I would never understand how to build an airplane or at least be as proficient with tools as my father, the aeronautical engineer. Even though my sister was six years older than I was, I lamented that I would never be as good a visual artist as she was. And I marveled at my mother’s seemingly magical ability to make and tailor clothes and was certain that I would never attain her level of mastery. This habit of comparing myself to others grew over the years, continuing to subtly and effectively undermine my sense of self. I had almost reached an uneasy truce with my comparison habit when social media happened. As an early adopter of Twitter, I loved staying connected to people I met a… | 2017 | Denise Jacobs | denisejacobs | 2017-12-19T00:00:00+00:00 | https://24ways.org/2017/do-a-media-detox/ | process |
| 208 | 208 | All That Glisters | Tradition has it that at this time of year, families gather together, sit, eat and share stories. It’s an opportunity for the wisdom of the elders to be passed down to the younger members of the tribe. Tradition also has it that we should chase cheese downhill and dunk the nice lady to prove she’s a witch, so maybe let’s not put too much stock in that. I’ve been building things on the web professionally for about twenty years, and although the web has changed immeasurably, it’s probably not changed as much as I have. While I can happily say I’m not the young (always right, always arrogant) developer that I once was, unfortunately I’m now an approaching-middle-age developer who thinks he’s always right and on top of it is extremely pompous. What can you do? Nature has devised this system with the distinct advantage of allowing us to always be right, and only ever wrong in the future or in the past. So let’s roll with it. Increasingly, there seems to be a sense of fatigue within our industry. Just when you think you’ve got a handle on whatever the latest tool or technology is, something new comes out to replace it. Suddenly you find that you’ve invested precious time learning something new and it’s already old hat. The pace of change is so rapid, that new developers don’t know where to start, and experienced developers don’t know where it ends. With that in mind, here’s some fireside thoughts from a pompous old developer, that I hope might bring some Christmas comfort. Reliable and boring beats shiny and new There are so many new tools, frameworks, techniques, styles and libraries to learn. You know what? You don’t have to use them. You’re not a bad developer if you use Grunt even though others have switched to Gulp or Brunch or Webpack or Banana Sandwich. It’s probably misguided to spend lots of project time messing around with build tool fashions when your so last year build tool is already doing what you need. Just a little reminder that it’s about 100 times more important what you build than how you build it.— … | 2017 | Drew McLellan | drewmclellan | 2017-12-24T00:00:00+00:00 | https://24ways.org/2017/all-that-glisters/ | business |
| 209 | 209 | Feeding the Audio Graph | In 2004, I was given an iPod. I count this as one of the most intuitive pieces of technology I’ve ever owned. It wasn’t because of the the snazzy (colour!) menus or circular touchpad. I loved how smoothly it fitted into my life. I could plug in my headphones and listen to music while I was walking around town. Then when I got home, I could plug it into an amplifier and carry on listening there. There was no faff. It didn’t matter if I could find my favourite mix tape, or if my WiFi was flakey - it was all just there. Nowadays, when I’m trying to pair my phone with some Bluetooth speakers, or can’t find my USB-to-headphone jack, or even access any music because I don’t have cellular reception; I really miss this simplicity. The Web Audio API I think the Web Audio API feels kind of like my iPod did. It’s different from most browser APIs - rather than throwing around data, or updating DOM elements - you plug together a graph of audio nodes, which the browser uses to generate, process, and play sounds. The thing I like about it is that you can totally plug it into whatever you want, and it’ll mostly just work. So, let’s get started. First of all we want an audio source. <audio src="night-owl.mp3" controls /> (Song - Night Owl by Broke For Free) This totally works. However, it’s not using the Web Audio API, so we can’t access or modify the sound it makes. To hook this up to our audio graph, we can use an AudioSourceNode. This captures the sound from the element, and lets us connect to other nodes in a graph. const audioCtx = new AudioContext() const audio = document.querySelector('audio') const input = audioCtx.createAudioSourceNode(audio) input.connect(audioCtx.destination) Great. We’ve made something that looks and sounds exactly the same as it did before. Go us. Gain Let’s plug in a GainNode - this allows you to alter the amplitude (volume) of an an audio stream. We can hook this node up to an <input> element by setting the gain property of the node. (The syntax for this is kind of weird because it’s an Au… | 2017 | Ben Foxall | benfoxall | 2017-12-17T00:00:00+00:00 | https://24ways.org/2017/feeding-the-audio-graph/ | code |
| 210 | 210 | Stop Leaving Animation to the Last Minute | Our design process relies heavily on static mockups as deliverables and this makes it harder than it needs to be to incorporate UI animation in our designs. Talking through animation ideas and dancing out the details of those ideas can be fun; but it’s not always enough to really evaluate or invest in animated design solutions. By including deliverables that encourage discussing animation throughout your design process, you can set yourself (and your team) up for creating meaningful UI animations that feel just as much a part of the design as your colour palette and typeface. You can get out of that “running out of time to add in the animation” trap by deliberately including animation in the early phases of your design process. This will give you both the space to treat animation as a design tool, and the room to iterate on UI animation ideas to come up with higher quality solutions. Two deliverables that can be especially useful for this are motion comps and animated interactive prototypes. Motion comps - an animation deliverable Motion comps (also called animatics or motion mock-ups) are usually video representation of UI animations. They are used to explore the details of how a particular animation might play out. And they’re most often made with timeline-based tools like Adobe After Effects, Adobe Animate, or Tumult Hype. The most useful things about motion comps is how they allow designers and developers to share the work of creating animations. (Instead of pushing all the responsibility of animation on one group or the other.) For example, imagine you’re working on a design that has a content panel that can either be open or closed. You might create a mockup like the one below including the two different views: the closed state and the open state. If you’re working with only static deliverables, these two artboards might be exactly what you handoff to developers along with the instruction to animate between the two. On the surface that seems pretty straight forward, but even with this relatively simple… | 2017 | Val Head | valhead | 2017-12-08T00:00:00+00:00 | https://24ways.org/2017/stop-leaving-animation-to-the-last-minute/ | design |
| 211 | 211 | Automating Your Accessibility Tests | Accessibility is one of those things we all wish we were better at. It can lead to a bunch of questions like: how do we make our site better? How do we test what we have done? Should we spend time each day going through our site to check everything by hand? Or just hope that everyone on our team has remembered to check their changes are accessible? This is where automated accessibility tests can come in. We can set up automated tests and have them run whenever someone makes a pull request, and even alongside end-to-end tests, too. Automated tests can’t cover everything however; only 20 to 50% of accessibility issues can be detected automatically. For example, we can’t yet automate the comparison of an alt attribute with an image’s content, and there are some screen reader tests that need to be carried out by hand too. To ensure our site is as accessible as possible, we will still need to carry out manual tests, and I will cover these later. First, I’m going to explain how I implemented automated accessibility tests on Elsevier’s ecommerce pages, and share some of the lessons I learnt along the way. Picking the right tool One of the hardest, but most important parts of creating our automated accessibility tests was choosing the right tool. We began by investigating aXe CLI, but soon realised it wouldn’t fit our requirements. It couldn’t check pages that required a visitor to log in, so while we could test our product pages, we couldn’t test any customer account pages. Instead we moved over to Pa11y. Its beforeScript step meant we could log into the site and test pages such as the order history. The example below shows the how the beforeScript step completes a login form and then waits for the login to complete before testing the page: beforeScript: function(page, options, next) { // An example function that can be used to make sure changes have been confirmed before continuing to run Pa11y function waitUntil(condition, retries, waitOver) { page.evaluate(condition, function(err, result) { if (result … | 2017 | Seren Davies | serendavies | 2017-12-07T00:00:00+00:00 | https://24ways.org/2017/automating-your-accessibility-tests/ | code |
| 212 | 212 | Refactoring Your Way to a Design System | I love refactoring code. Absolutely love it. There’s something about taking a piece of UI or a bit of code and reworking it in a way that is simpler, modular, and reusable that makes me incredibly happy. I also love design systems work. It gives hybrids like me a home. It seems like everyone is talking about design systems right now. Design systems teams are perfect for those who enjoy doing architectural work and who straddle the line between designer and developer. Una Kravets recently identified some of the reasons that design systems fail, and chief among them are lack of buy-in, underlying architecture, and communication. While it’s definitely easier to establish these before project work begins, that doesn’t mean it is the only path to success. It’s a privilege to work on a greenfield project, and one that is not afforded to many. Companies with complex and/or legacy codebases may not be able to support a full rewrite of their product. In addition, many people feel overwhelmed at the thought of creating a complete system and are at a loss of how or where to even begin the process. This is where refactoring comes into play. According to Martin Fowler, “refactoring is the process of changing a software system in such a way that it does not alter the external behavior of the code yet improves its internal structure.” It’s largely invisible work, and if you do it right, the end user will never know the difference. What it will do is provide a decent foundation to begin more systematic work. Build a solid foundation When I was first asked to create Pantsuit, the design system for Hillary for America, I was tasked with changing our codebase to be more modular and scalable, without changing the behavior or visual design of the UI. We needed a system in place that would allow for the rapid creation of new projects while maintaining a consistent visual language. In essence, I was asked to refactor our code into a design system. During that refactor, I focused the majority of my efforts on creating a scalable arch… | 2017 | Mina Markham | minamarkham | 2017-12-23T00:00:00+00:00 | https://24ways.org/2017/refactoring-your-way-to-a-design-system/ | code |
| 213 | 213 | Accessibility Through Semantic HTML | Working on Better, a tracker blocker, I spend an awful lot of my time with my nose in other people’s page sources. I’m mostly there looking for harmful tracking scripts, but often notice the HTML on some of the world’s most popular sites is in a sad state of neglect. What does neglected HTML look like? Here’s an example of the markup I found on a news site just yesterday. There’s a bit of text, a few links, and a few images. But mostly it’s div elements. <div class="block_wrapper"> <div class="block_content"> <div class="box"> <div id="block1242235"> <div class="column"> <div class="column_content"> <a class="close" href="#"><i class="fa"></i></a> </div> <div class="btn account_login"></div> Some text <span>more text</span> </div> </div> </div> </div> </div> divs and spans, why do we use them so much? While I find tracking scripts completely inexcusable, I do understand why people write HTML like the above. As developers, we like to use divs and spans as they’re generic elements. They come with no associated default browser styles or behaviour except that div displays as a block, and span displays inline. If we make our page up out of divs and spans, we know we’ll have absolute control over styles and behaviour cross-browser, and we won’t need a CSS reset. Absolute control may seem like an advantage, but there’s a greater benefit to less generic, more semantic elements. Browsers render semantic elements with their own distinct styles and behaviours. For example, button looks and behaves differently from a. And ul is different from ol. These defaults are shortcuts to a more usable and accessible web. They provide consistent and well-tested components for common interactions. Semantic elements aid usability A good example of how browser defaults can benefit the usability of an element is in the <select> option menu. In Safari on the desktop, the browser renders <select> as a popover-style menu. On a touchscreen, Safari overl… | 2017 | Laura Kalbag | laurakalbag | 2017-12-15T00:00:00+00:00 | https://24ways.org/2017/accessibility-through-semantic-html/ | code |
| 214 | 214 | Christmas Gifts for Your Future Self: Testing the Web Platform | In the last year I became a CSS specification editor, on a mission to revitalise CSS Multi-column layout. This has involved learning about many things, one of which has been the Web Platform Tests project. In this article, I’m going to share what I’ve learned about testing the web platform. I’m also going to explain why I think you might want to get involved too. Why test? At one time or another it is likely that you have been frustrated by an issue where you wrote some valid CSS, and one browser did one thing with it and another something else entirely. Experiences like this make many web developers feel that browser vendors don’t work together, or they are actively doing things in a different way to one another to the detriment of those of us who use the platform. You’ll be glad to know that isn’t the case, and that the people who work on browsers want things to be consistent just as much as we do. It turns out however that interoperability, which is the official term for “works in all browsers”, is hard. Thanks to web-platform-tests, a test from another browser vendor just found genuine bug in our code before we shipped 😻— Brian Birtles (@brianskold) February 10, 2017 In order for W3C Specifications to move on to become W3C Recommendations we need to have interoperable implementations. 6.2.4 Implementation Experience Implementation experience is required to show that a specification is sufficiently clear, complete, and relevant to market needs, to ensure that independent interoperable implementations of each feature of the specification will be realized. While no exhaustive list of requirements is provided here, when assessing that there is adequate implementation experience the Director will consider (though not be limited to): is each feature of the current specification implemented, and how is this demonstrated? are there independent interoperable implementations of the current specification? are there implementations created by people other than the authors of the specification? are implementations publi… | 2017 | Rachel Andrew | rachelandrew | 2017-12-10T00:00:00+00:00 | https://24ways.org/2017/testing-the-web-platform/ | code |
| 215 | 215 | Teach the CLI to Talk Back | The CLI is a daunting tool. It’s quick, powerful, but it’s also incredibly easy to screw things up in – either with a mistyped command, or a correctly typed command used at the wrong moment. This puts a lot of people off using it, but it doesn’t have to be this way. If you’ve ever interacted with Slack’s Slackbot to set a reminder or ask a question, you’re basically using a command line interface, but it feels more like having a conversation. (My favourite Slack app is Lunch Train which helps with the thankless task of herding colleagues to a particular lunch venue on time.) Same goes with voice-operated assistants like Alexa, Siri and Google Home. There are even games, like Lifeline, where you interact with a stranded astronaut via pseudo SMS, and KOMRAD where you chat with a Soviet AI. I’m not aiming to build an AI here – my aspirations are a little more down to earth. What I’d like is to make the CLI a friendlier, more forgiving, and more intuitive tool for new or reluctant users. I want to teach it to talk back. Interactive command lines in the wild If you’ve used dev tools in the command line, you’ve probably already used an interactive prompt – something that asks you questions and responds based on your answers. Here are some examples: Yeoman If you have Yeoman globally installed, running yo will start a command prompt. The prompt asks you what you’d like to do, and gives you options with how to proceed. Seasoned users will run specific commands for these options rather than go through this prompt, but it’s a nice way to start someone off with using the tool. npm If you’re a Node.js developer, you’re probably familiar with typing npm init to initialise a project. This brings up prompts that will populate a package.json manifest file for that project. The alternative would be to expect the user to craft their own package.json, which is more error-prone since it’s in JSON format, so something as trivial as an extraneous comma can throw an error.

| 216 | 216 | Styling Components - Typed CSS With Stylable | There’s been a lot of debate recently about how best to style components for web apps so that styles don’t accidentally ‘leak’ out of the component they’re meant for, or clash with other styles on the page. Elaborate CSS conventions have sprung up, such as OOCSS, SMACSS, BEM, ITCSS, and ECSS. These work well, but they are methodologies, and require everyone in the team to know them and follow them, which can be a difficult undertaking across large or distributed teams. Others just give up on CSS and put all their styles in JavaScript. Now, I’m not bashing JS, especially so close to its 22nd birthday, but CSS-in-JS has problems of its own. Browsers have 20 years experience in optimising their CSS engines, so JavaScript won’t be as fast as using real CSS, and in any case, this requires waiting for JS to download, parse, execute then render the styles. There’s another problem with CSS-in-JS, too. Since Responsive Web Design hit the streets, most designers no longer make comps in Photoshop or its equivalents; instead, they write CSS. Why hire an expensive design professional and require them to learn a new way of doing their job? A recent thread on Twitter asked “What’s your biggest gripe with CSS-in-JS?”, and the replies were illuminating: “Always having to remember to camelCase properties then spending 10min pulling hair out when you do forget”, “the cryptic domain-specific languages that each of the frameworks do just ever so slightly differently”, “When I test look and feel in browser, then I copy paste from inspector, only to have to re-write it as a JSON object”, “Lack of linting, autocomplete, and css plug-ins for colors/ incrementing/ etc”. If you’re a developer, and you’re still unconvinced, I challenge you to let designers change the font in your IDE to Zapf Chancery and choose a new colour scheme, simply because they like it better. Does that sound like fun? Will that boost your productivity? Thought not. Some chums at Wix Engineering and I wanted to see if we could square this circle.
