JS Roundup: Episode 03
In this episode, we’ll cover Svelte September updates, Deno 1.14 and Meteor 2.4 releases, exciting news about SolidJS and Netlify, and more!
Below you’ll find the transcript of the video. We’ve added it here for those who prefer to read rather than watch. It also contains links to additional information.
Paul Everitt: I really enjoy watching the HTTP 203 show on YouTube from the Google Chrome developers. They had a show recently about Deno, and my choice for September comes from the Deno 1.14 release.
A couple of things in there really stuck out to me.
First, the customization options for
deno lint and
deno fmt. I find it cool that they’re bundling their own linter and their own formatter, a bit like Golang does. They’ve made it a little bit more customizable. It worked for me the first time – I plugged it in, made a couple of changes, and ran it. It reformatted my code and my tsconfig.json file, which I thought was pretty cool.
Svelte September updates
Ebenezer Don: What’s new in Svelte in September of 2021? Svelte started this month by being named Stack Overflow’s most loved web framework. I’d have guessed some other frameworks which have been out there for a while, but we’ve chosen Svelte.
In September, Svelte gave us new updates and performance improvements, one of which is the update to
use:actions. It can now be used on
<svelte:body>. You know the actions that are element level lifecycle functions which we use on HTML elements? We can now use them on the HTML body.
There’s now less code in Svelte output. We had this issue, which was created in February by AradAral. One of the things he highlighted was that “since multiple whitespaces, tabs, and line breaks inside HTML attribute values are always ignored by browsers and cause no functional difference, the Svelte compiler could easily ignore these characters, and ‘normalize’ the whitespaces in attribute values, without causing any harm”. Right now this is fixed. Svelte has made the performance improvement, and we no longer have as many whitespaces in Svelte output.
Hydrated components have also been updated to only rely upon helpers for creating the types of elements present in the component.
Scaling is now accounted for in flip animations and all
<option>s in a
<select> are now deselected when the bound value doesn’t match any of them.
I must comment on how quickly the Svelte team is able to respond to requests. I see issues that were filed in August and already fixed in September – I think that’s really awesome! To read more about Svelte’s September 2021 updates, please check out the changelog.
Paul: It’s really interesting to see what you’re talking about. You made a comment about how quickly they respond to changes and I want to ask you, Ebenezer, it seems like this whole idea about a compiler has really captured everybody’s imagination and is starting to influence the thinking in other frameworks. Do you agree?
Ebenezer: I do, I do agree with that. And I think the fact that we have multiple frameworks right now that are trying to make performance the center of their work is making a lot of other frameworks work towards that goal. So it’s kind of like having competition in the market and we’re seeing amazing results.
createIndex, additional email package features, and runtime performance improvements.
Paul: I’ve been around for a while, but it sure seems like Meteor’s been around a long time. Do you agree?
Ebenezer: Yes, it’s really interesting how they manage to still do all these integrations. Mature projects sometimes run out of energy, so it’s cool to see Meteor still tackling all these new problems.
Ebenezer: In September, NestJS hit 40,000 stars on GitHub. NestJS is a progressive Node.js framework for building efficient and scalable server-side applications. It’s really amazing to see this framework hitting such a big milestone. What do you think about NestJS, Paul?
Paul: I was going to comment that they do have some innovative ideas, and I’ve been enjoying watching the rollout of NestJS.
Paul: How about I talk about Next.js, which had a 11.1 release. It was in August, but I didn’t notice until September, so I’m going to talk about it real quick.
Netlify and SolidJS
Ebenezer: Netlify joins SolidJS as an official deployment partner and sponsor. This is really exciting, and I see a really bright feature for SolidJS with lots of improvements and updates coming soon.
Paul: My small contribution to the second episode of JS Roundup was talking about Ryan Carniato, the creator of SolidJS, and his articles. He’s got a really open and inclusive attitude and it looks like Netlify agrees with him.
