Hello wasm-pack!

wasm-pack is a tool for assembling and packaging Rust crates that target WebAssembly. These packages can be published to the npm Registry and used alongside other packages. This means you can use them side-by-side with JS and other packages, and in many kind of applications, be it a Node.js server side app, a client-side application bundled by Webpack, or any other sort of application that uses npm dependencies. We're recording a show with Lin Clark today and will definitely ask her all about the progress Mozilla folks have been making on merging the JavaScript and Rust worlds via WebAssembly. Exciting times!

🎼 ChordFiddle – your online playground for ChordPro chord sheets

Like JSFiddle, but for ChordPro chord sheets. I'm no musician, so I'm not embarrassed to say I had to google to learn ChordPro is an ASCII text file format for transcribing songs with chords and lyrics. ChordFiddle is loaded with features and has more coming on the project board. Look under the hood and you'll find two more open source libs: ChordSheetJS and ChordJS.

PWAs are going to eat the (app) world

Yesterday's bearish link about PWAs caused a bit of a stir in our community Slack. Here comes the bull: PWAs are going to be versatile enough and robust enough that they're going to supplant some of the native apps you might have on your phone (or computer) today. I appreciate the caution on display by use of the word "some". Jon may be bullish, but he's not a zealot! Why does he think PWAs will finally get over the hurdle? One acronym: WASM With the ease of install of PWAs and high performance of WASM, I think we're also going to see some Electron apps moving to be PWAs. Great article. Definitely click through and read the whole thing. 💯

I built a PWA and published it in three app stores. Here’s what i learned...

Judah Gabriel starts this post off with the question "Why even put your app in the app stores? Just live on the opened web!” — and I don't fully disagree, until you think about where your users will come from. The answer, in a nutshell, is because that’s where the users are. We’ve trained a generation of users to find apps in proprietary app stores, not on the free and open web. There are many more lessons learned about the process — from creation to submission — but here's the tldr... Turning a web app into a Progressive Web App (PWA) and submitting it to 3 app stores requires about a month of work, a few hundred dollars, and lots of red tape. (We're planning a deep-dive on PWAs for an upcoming episode of JS Party. Subscribe to be notified.)

VuePress – a Vue-powered static site generator

Here's a shiny new new project from Vue's creator. There are plenty of static site generators in the wild, but most of them are created with blogging or generic content in mind. VuePress has a specific angle: VuePress is composed of two parts: a minimalistic static site generator with a Vue-powered theming system, and a default theme optimized for writing technical documentation. It was created to support the documentation needs of Vue’s own sub projects. The default theme looks great (no surprise there) and the supporting documentation/story telling around VuePress is quite impressive as well. But perhaps you're wondering, "Why not $X?", where $X is a similar alternative. Here's why.

I wasn't ready to become the maintainer of Babel

I wasn't ready to become the maintainer of Babel. After all, I had never published my own npm package or explored much of the codebase. But slowly (sometimes really slowly) I got used to it. I recall Kent C. Dodds saying that if you want to be a maintainer, just act like and do the things a maintainers does. Sounds easy enough 🤣. I particularly enjoyed the linked post on imposter syndrome from Rachel Smith.

Jeremy Keith A List Apart

Going offline

Jeremy Keith in an excerpt from his new book Going Offline on A List Apart: The internet is a network of networks, all of them agreeing to use the same protocols to shuttle packets of data around. Those packets are transmitted down fiber-optic cables across the ocean floor, bounced around with Wi-Fi or radio signals, or beamed from satellites in freakin’ space. As long as these networks are working, the web is working. But sometimes networks go bad… When the network fails, the web fails. That’s just the way it is, and there’s nothing we can do about it. Until now. I'm really excited to see Jeremy Keith write a whole book on service workers. I've dabbled a bit here and there, but now that support for them continues to grow, I'm excited to dive in.

Winamp2 JS with Jordan Eldredge

Jordan Eldredge joined the show to talk with us about Winamp2-js — a reimplementation of Winamp 2.9 in HTML5 and Javascript. For many of our listeners, talking about Winamp may bring to mind some extreme nostalgia about the internet of the past ... and it's certainly that way for Jerod and I. Jordan started this project in 2014 and it's what ultimately got the attention of some folks at Facebook, where he now works on Nuclide. We shared stories about Winamp back in the day, actually listening to music as an mp3, the technical hurdles and learning Jordan has experienced, skinning it, playlists, making it a frontend for Spotify -- which is so ironic to actually say. Also, Jerod has been hacking it via livestream on Twitch to add it as an alternate audio player on Changelog.com.

Glitch celebrates v1.0 with a week of major announcements

Today Glitch, the “friendly community where you’ll build the app of your dreams”, is officially “tearing off the beta label”. To celebrate, they’ve made a major announcement each day this week. The announcements include Glitch for Teams, “Making Learning to Code More Accessible” by adding embed support, “Tackling the Biggest Pain Points in Web Development” by adding things like “full-stack view source”, “Reinventing Version Control with Glitch Rewind”, and open-sourcing the Glitch.com app which will allow the community to remix the site to suggest ideas. Glitch is super exciting to me. Their efforts to make development more accessible, appealing, and fun will likely have profound effects on the community in the coming years.

JavaScript breaks into IoT via JerryScript

Michelle Gienow: The recent release of the Fitbit Ionic marked Fitbit’s first true smartwatch. More significant to the JavaScript developer community, though, is the fact that the Ionic was produced and shipped using JerryScript, a lightweight JavaScript engine built to power the Internet of Things. I heard some hubbub about JerryScript last year at OSCON EU, but not much since. Fitbit using it in their first attempt at a production smart watch is a big vote of confidence for the project.

Vue.js gets a cookbook 👩‍🍳

Unlike the guide which walks you through building a Vue app in story form, the cookbook is all about focused examples of how to accomplish specific goals with the framework. This is an excellent addition to the compendium of documentation in support of the project, and one that’s worthy of emulation once your framework has a base set of docs that are solid.

Everyone can now run JavaScript on Cloudflare with Service Workers

Cloudflare gave Kenton Varda a mission — Make it so developers could run code on Cloudflare's edge. Kenton Varda, writes on the Cloudflare blog: Eventually, we settled on what now seems the obvious choice: JavaScript, using the standard Service Workers API, running in a new environment built on V8. Five months ago, we gave you a preview of what we were building, and started the beta. Today, with thousands of scripts deployed and many billions of requests served, Cloudflare Workers is now ready for everyone.

Eleventy - a simpler static site generator

When Zach isn’t going on and on about web fonts, he’s making great open source software. His newest project, Eleventy, has successfully renewed my interest in static site generators. It feels much more intuitive than I remember Jekyll being (it’s been a few years) and the fact that it supports many different template engines makes it easy to jump in. Zach was also recently awarded an Open Source Peer Bonus from Google for his work on Eleventy.
