Since the start of this newsletter we've been virtue signalling about how we don't have ads. Turns out, by selling ads we can make money, and by making money we can buy things that give us short term pleasure but ultimately leave us feeling even more empty in the long term. We can't wait.
To better help us in our mission, we need to collect some (anonymous) data about you, our loyal and non-judgemental reader.
Here's a quick survey you can take. To better incentivize you to help us make money, we're giving away a pair of AirPods Pros to 3 random participants. (Jokes aside, thank you! ❤️)
The more things change, the more they stay the same
After taking a year off in 2020 because of Covid, Google I/O was back with a bang last week. We're a little bummed we didn't get another chat app, per tradition, but we did get:
But the real crème de la crème came when they unveiled the new Firebase updates.
Quick review: Firebase was co-founded in 2011 by James Tamplin. Who's James Tamplin? He looks like Ryan Key. Who's Ryan Key? He sang Ocean Avenue. What's Ocean Avenue? It's where I used to sit and talk with you. We were both 16 and it felt so right, sleepin' all day staying up all, ni-ight. Firebase started out as a realtime database tool and was acquired by Google in 2014. Today, Firebase is a fully-loaded BaaS platform with solutions for hosting, cloud storage, authentication, notifications, and a lot more. Over 3 million apps use it every month, and it's only sometimes used by Google to help track users, allegedly.
But now that we sell ads too, we've lost our moral high ground. So here's the cool, new Firebase updates:
Cloud storage in the Emulator Suite -- Firebase's Local Emulator Suite lets you run emulated versions of their backend products on your own machine. This new Storage Emulator lets you upload, download, and modify files like you would in production (except you're not actually in production).
Remote Config updates -- Remote Config is all about giving you dynamic control of your app, so you can do stuff like A/B tests and personalized content. There are a bunch of new Remote Config features, including a redesigned console, an updated (and much easier to navigate) publish flow and A/B test results page, and a new Personalization feature that uses ML to automatically tailor your users' app experiences to maximize your stated objectives (like revenue or engagement).
Real-time performance monitoring -- Now you can clutch your laptop in terror while you monitor your app's performance in real time right after you launch a big update.
Now all we need is for Firebase to use some of its Google-bucks to book Johnny Hatton to perform with his fire bass at Google I/O 2022. I'll run it by Ryan, I mean James.
Don't call it a comeback
Block off some "Deep Work" time on your calendar and shake off your online conference fatigue because the hottest ticket in tech is back.
v2021 of Next.js Conf kicks off on June 15th and you're invited.
In true Vercel fashion, they're taking a "less is more" approach. According to the calendar invite, the conference starts at 9:00am PDT with the "After-party" starting just 30 minutes later at 9:30 ~~then after the party it's the hotel lobby~~.
We're not sure what Vercel has up their sleeve, but it's a safe assumption it'll make your life better. You can claim your spot here - Claim Your Ticket.
p.s. When you sign up you're given your own personal ticket. I haven't confirmed this, but I'm pretty sure the lower your number the better of a developer you are 😉.
VC backed code spaces/sandboxes/repls
Leveraging WebAssembly, Stackblitz just put Node.js in the browser, like, for real - and it's incredibly impressive. Why is this important and what does it mean? Let's back up a little.
How did we get here? WebAssembly's promise was to let any code run anywhere. The Wasm standard includes the WebAssembly System Interface (WASI), which serves as an interface between WebAssembly and the host operating system. It lets Wasm programs access the file system or open network sockets, so long as there is an OS to answer those calls. Too bad browsers don't include an OS like that.
Enter WebContainers -- StackBlitz's two-year labor of love is a browser-based OS which connects WASM/WASI programs to browser APIs. It's early stage, but they already have a file system (thanks to the Chrome FileSystem Access API), networking (HTTP only for now, but that might change soon), threads and process management, and a POSIX shell.
The first application is a browser-based editor that combines VSCode and Node.js with zero installations and is able to boot in milliseconds.
You get speed, you get security, and you get consistency. For better or worse, you won't be able to use "it worked on my machine" as an excuse, because it works the same on every machine. No more setting up local environments, and no more code spaces/sandboxes/repls.
The WebContainers project was inspired by a quote from Alan Kay (the creator of Graphical User Interfaces): "You want [the web] to be a mini-operating system, and the people who did the browser mistook it as an application."
WebContainers helps push browsers towards that mini-OS vision. Today it's mostly helpful for just setting up a Node.js dev environment speedy-quick. But this kind of OS could eventually run any program written in any language, exactly the same as if it were actually installed. Photoshop. CAD. Fortnite. You name it.
Are you bad at CSS? lol of course you are. Good news is long time Senior Developer Advocate at Google and all around lovely human being David East has you covered in his new (video) podcast. Introducing the Bad at CSS Podcast - the podcast for kids who cant CSS good and want to learn how to do other stuff good too.
Google released a free course called Learn CSS, that does a great job covering all the CSS fundamentals. Because even Johnny Hatton had to master the fundamentals of standup bass before he could shred like this.
Alex Reardon created DOM Events -- a cool, colorful way to visualize and experiment with the DOM Event system so that you can finally (maybe) understand how it actually works.
Celso Martinho (Director of Engineering at Cloudflare) wrote about recreating the original Doom video game on top of Cloudflare's edge network using durable objects, Websockets, Workers, and Wasm (!!). You can play it here. It's definitely a much better product than the Doom Movie from 2005 that received a very generous 18% on Rotten Tomatoes.
Ali Spittel created a Complete Beginner's Guide to Next.js just in time for you to feel included in Next.js Conf next month.
Iconic is a collection of high-quality icons that are 100% free to use. The only catch is that the author requires attribution in the form of an inner lip tattoo.
Adam Rackis wrote a great article on Svelte for the experienced React dev. How do you know if you're an "experienced" React dev? Have you ever DDoS'ed your own server using
useEffect? If so, you're in.
Microsoft is officially retiring Internet Explorer in June 2022. Bad news for your Grandma who hasn't updated her PC since 2008, good news for literally everyone else.

This is the first ever newsletter that I open a music playlist for and maximize my browser window just to read it in peace. Kudos to @uidotdev for great weekly content.
The Bytes newsletter is a work of art! It's the only dev newsletter I'm subscribed too. They somehow take semi boring stuff and infuse it with just the right amount of comedy to make you chuckle.
Bytes has been my favorite newsletter since its inception. It's my favorite thing I look forward to on Mondays. Goes great with a hot cup of coffee!
I subscribe to A LOT of dev (especially JS/TS/Node) newsletters and Bytes by @uidotdev is always such a welcomed, enjoyable change of pace to most (funny, lighthearted, etc) but still comprehensive/useful.
Literally the only newsletter I’m waiting for every week.
Bytes is the developer newsletter I most look forward to each week. Great balance of content and context! Thanks @uidotdev.
The sense of humor and structure of the Bytes Newsletter is first class and the information that comes with it is enough to make a mini course.
Very few newsletters manage to be useful and not very boring. @uidotdev manages to achieve these pretty effortlessly. You can almost see Tyler chuckle as he writes them.
