For those who like to implement both light and dark themes and want to do that in the most optimized way I have good news for you Google Recently implemented in Chrome > 93 the ability to get the user preference using server-side technologies.
Why is that important? Because just in case you didn’t hear the term FART by now it stands for “Flash of inAccurate coloR Theme”, the main issue is that if you don’t know the user preference before sending a response to a request, you can optimally set the user preferred theme.
On many websites, you can have content embedded from other sites and one way that most external sites will offer will be to include a script that’s hosted on their website.
But if all that script does is including some remote content there are better ways to get that, that will provide customizations and performance.
For example, the website Goodreads offers such an embed JS with a list of the latest books you read, and you must include the script where you want the content to be shown. But that has a long list of drawbacks: the script uses the old API
document.write, is a script and can’t be loaded in AMP, the scripts write very old style HTML with tags like center, attributes like border which again is not valid AMP, then also that script will be loaded for every request, so you’ll have one additional request. View full article
There are a lot of commenting system plugins out there but most of them come with a cost, and sometimes just building a simple WordPress commenting system on top of the native commenting system can be enough.
The main features of this system will be:
- Comments will be only loaded if the user clicks a button
- Comments will be submitted and fetched by JS
- Comments will have paginations fetched by JS
- Comments will have some JS interactivity
- Comments will have the reply feature enabled
- The comment system will have an AMP implementation
- The comment system will have a no JS implementation
- Comments will work the same on AMP with our own script
The first thing will have to do for our system is to make some custom REST API for the JS to fetch. View full article
And historically on single-core CPU’s threads practically transformed into loops underneath. But the main idea is that in many languages, an async behavior is very easily achieved, maybe you need a keyword, maybe you need a special class, but in general, it is simple.
Now if you want the easiest way to do something asynchronous in PHP it will be a little costly, you can do that by spawning a new PHP process directly from PHP. View full article
