If you want to load the post faster you can use JS to fetch your post, but on modern browsers probably preloading pages will be faster, the only drawback of preloading is that you’ll consume storage for your visitors even if they don’t visit the preloaded links, also with preloading links you will consume more bandwidth and resources on the server-side.
So if you want to stick with fetching with JS here is an example, but first, as a note, the example will not use the default REST API mostly because the default API only returns the content title and other attributes of the post and, we want to add things like Yoast data(without making two API request) also, in this case, will transfer some of the article template surrounding the content.

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
A couple months ago I made a Python-Vue app ( Flask PyWebCamWebMonitor ) for controlling webcams(live view/record/stream) attached to a Linux host.
It’s pretty straight forward you use pip3 to install it then you install it as a system service or you start it manually with a command that is registered on the system automatically after you installed the python package.
When I first released it I tested it on a Linux X86 host but my intention was to make the app work even on the smallest dev boards, so a few days ago I tried to install it on orange pi zero.
As expected I encountered some problems first, the problem is that installing NumPy which is a dependency of OpenCV which is a dependency of my app, was complicated because the NumPy was not available for arm devices and when you tried to install it from building it you ran out of memory and the kernel killed the building process, you can activate a swap, and increase your /tmp size to overcome these limitations but it is simple just to install NumPy from the APT repo with apt install python3-NumPy, that you don’t have to needlessly wait.
