It's been almost a decade since I've done a live coding stream. This will be fun!

Today I'll be migrating my website from React to Lit, which is a lightweight framework built around web components. I have the scaffolding set up mostly, so now it's time to get this done.

Come watch. Ask questions in chat! You don't need to create an account, just a username is needed to participate.

I've been really enjoying working with Wikidata lately, setting up automated accounts like @libraries, @parks, and @lighthouses.

To see what else you can do with Wikidata, and to learn how to use it, check out a tutorial I put together: https://stefanbohacek.com/blog/making-a-map-of-unesco-world-heritage-sites/

trying to implement a form submission progress bar in js, but XHR follows the success redirect without telling me (I want to access it and redirect the browser).

Fetch can opt out of that but doesn't have a progress api!

I think I found a workaround for XHR:

xhr.onreadystatechange = function() {

 if (this.readyState === this.DONE) {  
 window.location.href = this.responseURL  
 this.abort()  
 }

}

Hey, developers: The @reviewboard team's starting a new #Discord for devs to hang out, chat, and share what you're building.

https://discord.gg/saMCqHEZ

We have channels for #django, #python, #javascript / #typescript, #opensource, #gamedev, and more.

You don't need to use or contribute to Review Board to hang out. (But you can follow development there, if you want.)

We hope to see people come in and hang out. The aim is a friendly, diverse community of devs.

Feel free to pass along the invite!

A response to @cferdinandi 's recent post(s) on JavaScript and Web Components:
https://dev.to/maxart2501/javascript-is-not-the-problem-k4e

I know he didn't explain his position in details, so a 1800-word article sounds a little unfair, but I think dry and sharp statements need adequate context and analysis.

#JavaScript Geeks:

🤔 I really want to figure out how to make #FediThready be able to post to a Mastodon server WITHOUT requiring a back-end.

I'm pretty sure it's possible to do OAuth and store the token locally without one, but i would love it if someone could point me to an example of this rather than figuring it out from first principles.

You can turn off the “x packages are looking for funding” messages that get logged with each npm install by setting

fund = false

in your project’s or user’s npmrc file.

Another leak in the JavaScript single-threaded facade (or a bug in Jest, really).

Asserting expect(...).toStrictEqual(...) fails with two structurally identical objects created by two different Node worker threads because their prototypes are not the same (though identical). Asserting expect(structuredClone(...)).toStrictEqual(structuredClone(...)) works.
