Auto-filling forms is cool. Unless, of course, you give away more data than you thought you were. The basics It’s pretty simple, actually. You just add an autocomplete attribute to your <input> and give it one of the predefined values. And off you go. For example: <input type=”text” autocomplete=”given-name”> When the browser sees this, it […]
I’m a little late (like, omgbbq, 2 months late) with this announcement, but here goes: I published my new book, called “React: Up and Running”. Go get it everywhere where books are sold and learn React from the ground up! I’ve been working with React for a while now and thought I have something to […]
Warning: don’t do this. Stop it! Just. Don’t. So there’s this hack by Ben Foxall that shows how you can escape the browser window and draw outside the page. I had to try it myself. So here comes: the animated “progress” indicator mouse cursor. Wait what? There exists the ability for your web page to […]
Another one of those… This time it’s set to the music of “Gremmie outta control” by The silly surfers, covered by Pearl Jam And this time I’ve added some chords for your entertainment… C….. C Every team has a clown who thinks he knows it all (personal commitment to excellence that good enough is not […]
Originally published at http://phpadvent.org/ in 2009. The site is no more, but I found a copy on my hard drive. I’m not sure but I do hope it’s the final version because Sean Coates (@coates) and Chris Shiflett (@shiflett) did a really nice job editing the pice. Also hope it’s still funny… With the unemployment […]
As announced, starting with React v0.14 (next release), the JSXTransformer.js won’t be part of the release. Also `react-tools` npm package is no more. So whatchagonnawannado is switch to Babel. Here’s how. Build-time transform Prerequisite: install Babel $ npm install –global babel Where you previously had this as part of your development/build process: $ jsx –watch […]
Looks like Yahoo! stopped maintaining the image optimization service called smush.it. So people have been asking questions on the mailing list. I don’t have any inside information from Yahoo about the service, or whether it will be back up again. But let me try to answer some of the questions. History: quick refresher Nicole and […]
So I spoke at Facebook’s F8 in San Francisco last week. Actually my teammate Varun spoke mostly, I just interrupted a few times. Among other things we announced a new plugin – the embedded video player, so now you can embed any public FB video on your site. And, how meta!, below is a video […]
Here’s a video I made to raise awareness about Anaconda Limousine’s first album (where I play guitar and co-wrote 1 song): https://www.youtube.com/watch?v=0LavyKbSuvI. This is a post that explains how it was made so if anyone wants to made a similar one, they can have something to step on. Turns out videos like this are called […]
Say, a bunch of .wav files to .mp3 $ for f in *.wav; do ffmpeg -i $f “${f%.*}.mp3”; done
Update: Easier way to get top X URLs: http://httparchive.org/urls.php, thanks @souders Update: found and commented an offensive try{}catch(e){throw e;} in zombie.js (q.js, line 126), now the script doesn’t fatal that often Say you want to experiment or do some research with what’s out there on the web. You need data, real data from the web’s […]
Jest is a new javascript testing tool announced today. I thought I’d take it out for a spin testing the UI of a simple vanilla JS app – no CommonJS modules, no fancy stuff. Just old school JavaScript. Granted, it’s probably not what the tool was optimized to do, but it totally worked. The app […]
Continuing from last night… First, two twitter responses pointed to even more readily-available options for comparing screenshots. One is Wraith from BBC engineers which supports Firefox/Gecko (via SlimerJS) in addition to PhantomJS. The other is the almost-ready siteeffect.io which is based on http://dalekjs.com/ which seems to support all the browsers! Anyway, I thought I should […]
CSS is the worst because it blocks page rendering. The bigger it grows, the more it blocks. And bigger is what CSS becomes if left unattended, as anyone who has worked on any project for more than a few days or with more than a few people can confirm. So occasionally one must step back […]
In today’s world of always having some sort of code transformation before your JS/CSS/HTML reaches the user, e.g. minification, concatenation, es6-to-es3 transpilation, it’s nice to be able to go back to the source before the transformation. And when that happens in the comfort and the immediacy of the browser’s dev tools, even better! Enter source […]
So there’s this recent open-source project from Facebook called jstransform. It’s also used by ReactJS. It lets you explore ES6 features and not only explore, but use them in production code. All you need to do is add the transformation to your static resource pipeline. (Of course you have one, right, for minification and so […]
Beacons are small requests that our apps make to report some information “home”, to the server. Beacons are often used to report visitor stats, JS errors, performance metrics. Beacons often don’t return any data back to the client, but some do. Example use <div id="app">Awesome app is awesome</div> <script> // gather data somehow var data […]
Since IE9 and Firefox(v.?) we now have subpixel rendering of fonts. This is cool and all but imagine this: you have some text you want to measure the width of the text and size another element to the same dimensions Simple. But if you use offsetWidth/offsetHeight to measure, you get a rounded integer and not […]
Previously… React and tables. I’ve been meaning to improve a little on the table example built with React and a post by Steve was the final push. He shared his “ActiveTable” bookmarklet. So, introducing a bookmarklet to make it easier to work with random HTML tables you come across… ReActiveTable Drag this link to your […]
On my way to NYC for Edge conference and NYC Web perf meetup. Some slides and RSVP links inside.
Part 1 ended with todos. The first one was to couple the server-side generated code with the client-side React, so that any updates past the initial page load will be handled by React’s client JS, which is where React shines. Let’s see how you can do just that. PHP data fetch, gluing JS for v8 […]
Inspect the styles in Mobile Safari’s Reader feature to learn typography
Problem: Build web UIs Solution: React Problem: UI built in JS is anti-SEO (assuming search engines are still noscript) and bad for perceived performance (blank page till JS arrives) Solution: React page to render the first view Problem: Can’t host node.js apps / I have tons of PHP code Solution: Use PHP then! This post […]
Motivation? Run JS code inside PHP. Just… because 🙂 I struggled for a while with this installation, so leaving a trail here for anyone looking. What you need to accomplish? Goal: run JS code inside a PHP script running on a webserver. Already accomplished: Macs come with a webserver (Apache) and PHP. To get there: […]
In the previous post I mentioned the pains, misery and suffering attached to creating and updating an HTML table in DOM land. Now let’s see how you do this simple task in React. Demo React is all about components. So let’s build one. Let’s call it Table (to avoid any confusion what the component is […]
