SvelteKit Content Collections

Context

Just a quick note for easier sharing!

TL;DR for the impatient - all courtesy of Josh Nussbaum:

• code: https://github.com/joshnuss/sveltekit-content-blog
• docs: https://www.content-collections.dev/

Content Collections (e.g. for Markdown-based blogs) are a re-occuring topic and sometimes a pain point in my day-to-day work and for other Svelte / SvelteKit devs.

While Astro has a superb native content story (also used for this blog), SvelteKit has been lacking a viable solution so far. The new async + remote functions era will bring new momentum for sure - but that’s yet in the future.

In November 2024 I gave a talk about Svelte in Astro and also compared it against SvelteKit from a solo freelance dev’s point of view:

Ilja @fubits.dev

I gave a talk on this topic and now I realise that I should do a simple write-up. To me, the comparison is not so much about Astro vs Svelte. It’s rather about (Astro + Svelte) vs SvelteKit.

SvelteKit Content Collections: ???

Almost a year in I would evaluate a bunch of my claims differently now.

But more specifically, Svelte Core Maintainer Ben McCann actually pointed me to www.content-collections.dev as early as in May 2025. It’s open source: github.com/sdorra/content-collections. I just hadn’t had the time to test it yet.

Luckily, Josh Nussbaum did test it and released a 7-minute introduction on YouTube and also shared the code on GitHub:

So please,

• watch and upvote Josh’s video
• star Josh’s repo
• star sdorra/content-collections
• and spread the word!
