The Web Weekly newsletter keeps you up to date, teaches you web development tricks and covers all things working in tech.

Happy Sunday, party people! πŸ‘‹

Last week was super busy because of Jamstack conf. We were sponsoring the event, and I had the honor to give a workshop about Next.js and Contentful. It was a lot of work, but now that we have the materials, we might publish a course on the topic next year! πŸŽ‰

I'm looking forward to a chilled week and hope you're all well!

This week's Web Weekly includes:

  • All the web development areas one could know
  • The importance of real user performance metrics
  • New progressive web app features

... and, as always, GitHub repositories, a new Tiny Helper and some music.

"What should I learn when I want to become a web developer"?

Fundamentals section of the wek skills map.

That's a tricky question because web development includes way too many areas these days. But if someone asks me this question in the future, I'll look at Andreas Mehlsen's web skills project. It's an excellent overview of web development topics, and it includes study resources, too!

Look at all these web skills

Dynamic viewport units

I shared Bramus' article about the new viewport units in the past, but I came across his explainer again this week. There are so many exciting things coming to CSS these days!

How to blog

Recently plays a key role in keeping the blog alive: it is a routine. It has been extremely successful in keeping me aware that I had a place to write when I wanted to, and keeping a pulse here even when I haven’t been writing very often.

Oldie but goldie; if you're planning to start a blog, Tom MacWright has some great advice. I love the idea of "Recently posts".

Lighthouse scores are only half the story

Almost half of all pages that scored 100 on Lighthouse didn’t meet the recommended Core Web Vitals thresholds.

Web performance metrics can be gathered in the lab (your computer, WebPageTest, etc.) or the wild via RUM (real user monitoring). Phil Walton wrote a valuable piece explaining why it's crucial to track real user experience.

Why you should own your data – the Slideshare edition

Slideshare dialog that includes a payment opt out

This week I learned that the slide hosting service Slideshare started selling subscriptions. If you host your slides on the service, people now have to pay to download your content!

Sadly, it's just another story that shows the importance of content ownership. As Sara Soueidan said this week, "now might be a good time to owning your little corner of the internet" because no matter how great a platform or service is today, you'll never know what they'll do with your creations tomorrow.

Life pro tip: treat your phone like a book!

When outside treat your phone like it's a book. You wouldn't open a book during a conversation. You wouldn't be reading a book while driving.

I just love this advice from the blog. πŸ’™

Have you heard of OffscreenCanvas?

OffscreenCanvas is a solution to this. It's API surface is really small: It has a constructor, and a getContext('2d') method. Unlike the canvas element itself, however, it is neatly decoupled from the DOM. It can be used in a worker - in fact, they are tranferrable - you can pass them between windows and workers via postMessage.

I wanted to learn more about OffscreenCanvas for a while but sadly didn't find the time to understand this API's purpose. Luckily, Brian Kardell wrote an article about it! πŸ™ˆ

Transitional apps

Rich Harris promiting the hashtag "transitionapps"

My highlight of this year's Jamstack conf: Rich Harris takes a look at today's frontend architectures, explains the terms MPA (I still don't like the term) and SPA, and argues that the best solution is somewhere in the middle.

Will we build transitional apps?

PWA screenshots and shortcuts

Example showing how a PWA installation screen with screenshots looks like.

This month I learned that there are new PWA (progressive web app) features to spice up the installation dialog with screenshots and enable app shortcuts. I'm not very invested in the app space (and don't think every website needs to be a PWA), but these are cool features for sure.

TIL recap: CSS Grid can be used to stack elements

DevSheet explaining how to stack elements using CSS grid

I still haven't adopted this grid functionality entirely, but I learned that CSS grid can be used to stack elements a year ago.

Three valuable projects to have a look at

If you want to understand CSS filters and blend modes and learn how you can combine them, Filter Blend is perfect for that.

A quote to think about

I'm not into programming language discussions (or bashing). But it's a fact that if many people use something, all these people have opinions and complaints.

There are only two kinds of languages: the ones people complain about and the ones nobody uses.

A song that makes you stop coding

This week's song is from Berlin local Kat Frankie. "Bad behavior" is a catchy pop song from a great album.
