After months of anticipation, debate, and even a bit of apprehension, Svelte 5 arrived earlier this year. Frederick O’Brien caught up with its creator, Rich Harris, to talk about the path that brought him and his team here and what lies ahead.
Not Magic, But Magical
Svelte 5 is a ground-up rewrite. I don’t want to get into the weeds here — key changes are covered nicely in the migration guide — but suffice it say the big one where day-to-day users are concerned is runes. At times, magic feeling $ has given way to the more explicit $state, $derived, and $effect.
A Mature Framework
A lot of the talk around Svelte 5 included the sentiment that it marks the ‘maturation’ of the framework. To Harris and the Svelte team, it feels like a culmination, with lessons learned combined with aspirations to form something fresh yet familiar.
- This does sort of feel like a new chapter. I’m trying to build something that you don’t feel like you need to get a degree in it before you can be productive in it. And that seems to have been carried through with Svelte 5.
Growing Adoption
Although raw usage numbers aren’t everything, seeing the uptick in installations has been a welcome signal for Harris and the Svelte team.
- For us, success is definitely not based around adoption, though seeing the number go up and to the right gives us reassurance that we’re doing the right thing and we’re on the right track. Even if it’s not the goal, it is a useful indication. But success is really people building their apps with this framework and building higher quality, more resilient, more accessible apps.
Software Is Broken
Every milestone is a cause for celebration. It’s also a natural pause in which to ask, “Now what?” For the Svelte team, the sights seem firmly set on shoring up the quality of the web.
- A conclusion that we reached over the course of a recent discussion is that most software in the world is kind of terrible. Things are not good. Half the stuff on my phone just doesn’t work. It fails at basic tasks. And the same is true for a lot of websites. The number of times I’ve had to open DevTools to remove the disabled attribute from a button so that I can submit a form, or been unclear on whether a payment went through or not.
Brave New World
Part of Svelte 5 feels like a new chapter in the sense of fresh foundations. Anyone who’s worked in software development or web design will tell you how much of a headache ground-up rewrites are. Rebuilding the foundations is something to celebrate when you pull it off, but it also begs the question: What are the foundations for?
Onward
Although Svelte has been ticking along happily for years, the release of version 5 has felt like a new lease of life for the ecosystem around it. Every day brings new and exciting projects to the front page of the /r/sveltejs subreddit, while this year’s Advent of Svelte has kept up a sense of momentum following the stable release.
