If you aren’t building TypeScript I can’t guarantee it will work. That is also my personal account - not an officially supported project. I strongly recommend using our official tutorial first: https://developers.cloudflare.com/pages/framework-guides/deploy-a-svelte-site/#deploy-with-cloudflare-pages

Deploy a Svelte site · Cloudflare Pages docs

Svelte is an increasingly popular, open-source framework for building user interfaces and web applications. Unlike most frameworks, Svelte is …

I have that exact repo deployed as a project: if you're changing things it's probably breaking it.

I have deployed several sites already, following both the Cloudflare tutorial and Sveltekit's guide. Functions are proving a challenge.

I'll keep at it. What does your users database look like, do you have the schema?

C

crisOP•7/7/23, 12:18 AM

I see it from the output, email, id, etc. but I haven't actually added any tables to the db. I was hoping it would just return some system info to start. Maybe the error has to do with an incomplete db setup.

Matt Silverlock•7/7/23, 12:20 AM

It's impossible to tell from the error you've posted. If you haven't populated your DB - it won't work.

The query in the example app is just

"SELECT * FROM users LIMIT 5"

"SELECT * FROM users LIMIT 5"

— it doesn't matter what the schema is because the query doesn't do anything smart.

I'm off for the night, but I'd strongly recommend:

Going through the D1 tutorial first if you haven't. If you're also new to SvelteKit, then you're just adding friction: https://developers.cloudflare.com/d1/get-started/
Once you have that working, deploy a basic Svelte site to Pages: https://developers.cloudflare.com/pages/framework-guides/deploy-a-svelte-site/
Then you can combine it all

FIY -- https://temp-d1demo-ts.pages.dev/api/users it's working for me. I made a fresh repo with JSDoc and it didn't work. Then I made a fresh repo and created the sveltekit app with TypeScript and it worked. Thanks so much for this. It's really interesting to get this all combined and working.

Keep in mind that each Dynamo replica adds to your storage costs + adds additional replication costs. D1 will not for the 'default' global replication.

Matt Silverlock•7/7/23, 2:43 PM

Single writer: we think (and others like PlanetScale & Google's Spanner team also share this view) that multiple writers introduces too many consistency issues for user-facing apps. DynamoDB makes a bunch of trade-offs (and they are welcome to!) that we don't think are the right ones for user-facing apps / cause you to have to think about consistency a lot in your app design.

Matt Silverlock•7/7/23, 3:10 PM

I don't think single databases with terabytes of storage are likely, but I also don't think they make sense elsewhere. A Postgres database or MySQL database with > 100GB will start to see scaling and query performance issues. If you need a single DB with terabytes of storage there's likely an application architecture issue.
