SvelteFireTS

April 2024 Status Update: I still use this library in production and it's very useful, but I've moved on to using Supabase by and large. Because this library is stable, because the original SvelteFire gets a few updates here and there, and because I'm not expanding my use of Firebase, most active development has ceased. But it works great in SvelteKit 2 and Svelte 4. My recommendation is to read the docs, read the code, read Jeff's code, then copy what you need and hone it to your use case. You'll be a better developer for it.

As I've progressed in my understanding of how to use SvelteKit well, I've learned that it will make component design and mocking (I use Kitbook) much easier if you establish backend connections in the layout/page ts files and pass data and mutation operations to components via the page data prop. So that is why I say write your own. I presently no longer use the <Doc> and <Collection> components but solely lean on the getDoc, getCollection, docStore and collectionStore methods for this reason.

Easily use Firebase in Svelte. Built for SvelteKit 2.0+ but it could be used with any Svelte framework.

• SvelteKit (tested on 2.5.1)
• Typescript
• Firestore convenience helpers
• Auth store
• SSR ready (for unauthenticated data fetching)
• Firebase (tested on 10.9.0)
• includes an optional FirebaseAuthUi component that brings in FirebaseUI web + Firebase 10 compat via CDN only when component shown - FirebaseUI web allows for easy authentication in dozens of languages and many providers without you needing to manage the authentication forms

Usage Instructions

Open to Contributions

If there are any configuration settings or features you'd like to see added please create an issue to start a discussion about features you'd like. After discussion, hopefully you can add a pull request to implement such.

Note that the set helper method which automatically is either an update or a set depending on whether a document exists should really be renamed to upsert in order to make set more closely resemble Firestore's setDoc.

Developing

• pnpm install
• pnpm dev

Inspiration: Fireship.io

Jeff Delaney gets credit for much of SvelteFireTS. I started with SvelteFire then added Typescript, borrowed some convenient helpers from Jeff's Firestore Advanced Usage Angularfire, and made it work with SvelteKit's SSR + Client situation.
