Using React Loadable for Code Splitting by Components and Routes
7.3.2019
In a bid to have web applications serve needs for different types of users, it’s likely that more code is required than it would be for one type of user so the app can handle and adapt to different scenarios and use cases, which lead to new features and functionalities. When this happens, it’s...
The Client/Server Rendering Spectrum
6.3.2019
I've definitely been guilty of thinking about rendering on the web as a two-horse race. There is Server-Side Rendering (SSR, like this WordPress site is doing) and Client-Side Rendering (CSR, like a typical React app). Both are full of advantages and disadvantages. But, of course, the conversation...
The Bottleneck of the Web
5.3.2019
Steve Souders, "JavaScript Dominates Browser CPU":
Ten years ago the network was the main bottleneck. Today, the main bottleneck is JavaScript. The amount of JavaScript on pages is growing rapidly (nearly 5x in the last 7 years). In order to keep pages rendering and feeling fast, we need to focus...
A Bit of Performance
28.2.2019
Here’s a great post by Roman Komarov on what he learned by improving the performance of his personal website. There’s a couple of neat things he does to tackle font loading in particular, such as adding the <link rel="preload"> tags for fonts. This will encourage those font files...
instant.page
18.2.2019
instant.page is a pretty cool project from Alexandre Dieulot. Alexandre has been at this idea for half a decade now, as InstantClick is his and is essentially the same exact idea.
The idea is that there is a significant delay between hovering over a link and clicking that link. Say it takes...
Code Challenge #16: Infinite Scroll Unsplash Gallery
14.2.2019
Photos and media in general play a great part of websites and inefficient handling may lead to loss of site performance and ultimately, users. In this week's challenge, we will build a photo galler
“the closest thing web standards have to a golden rule”
14.2.2019
The internet's own Mat Marquis plucks this choice quote from the HTML Design Principals spec:
In case of conflict, consider users over authors over implementors over specifiers over theoretical purity.
And then he applies the idea to putting images on websites in 2019.

Bandwidth or Latency: When to Optimise for Which
5.2.2019
Harry Roberts:
A good rule of thumb to remember is that, for regular web browsing, improvements in latency would be more beneficial than improvements in bandwidth, and that improvements in bandwidth are noticed more when dealing with larger files.

Hey,
We need to act now to save our human living. It doesn’t matter that others don’t care, we as individuals need to make sure that we do everything we can to prevent our climate to go over into high-fever state (which is about 10 years away). It upon us to show companies that they need to...

Since the dawn of the web, performance has been an important factor for web development because slow speeds often lead to a loss of visitors and, ultimately, depletion in revenue for commercial sit
The Ethics of Web Performance
14.1.2019
Tim Kadlec on the issues surrounding poor web performance and why it’s so important for us to care about making our sites as fast as possible:
Poor performance can, and does, lead to exclusion. This point is extremely well documented by now, but warrants repeating. Sites that use an excess...

Fighting FOIT and FOUT Together
19.12.2018
Lots from Divya with the setup:
There are 2 kinds of problems that can arise when using webfonts; Flash of invisible text (FOIT) and Flash of Unstyled Text (FOUT) ... If we were to compare them, FOUT is of course the lesser of the two evils
If you wanna fight FOIT, the easiest tool is...
Google Fonts and font-display
19.12.2018
The font-display descriptor in @font-face blocks is really great. It goes a long way, all by itself, for improving the perceived performance of web font loading. Loading web fonts is tricky stuff and having a tool like this that works as well as it does is a big deal for the web.
It's such a...
How to Worry About npm Package Weight
18.12.2018
It's all too easy to go crazy with the imports and end up with megabytes upon megabytes of JavaScript. It can be a problem as that weight burdens each and every visitor from our site, very possibly delaying or stopping them from doing what they came to do on the site. Bad for them, worse for you....
Rendering Lists Using React Virtualized
13.12.2018
Working with data in React is relatively easy because React is designed to handle data as state. The hassle begins when the amount of data you need to consume becomes massive. For example, say you have to handle a dataset which is between 500-1,000 records. This can result in massive loads and lead...
Prototypes and production
11.12.2018
There’s an interesting distinction that Jeremy Keith defines between prototype code and production code in this post and I’ve been thinking about it all week:
...every so often, we use the materials of front-end development—HTML, CSS, and JavaScript—to produce something that isn’t intended...
Get Viewport Lines and Columns in CodeMirror
27.11.2018
CodeMirror is an amazing utility for presenting code in a browser environment. Syntax highlighting, widgets, and a number of advanced functions make it a unique, useful tool. When using CodeMirror inside the Firefox DevTools debugger, I found that adding hundreds of column breakpoint widgets...
