I am interested to start a new project using Pages but I want to use D1 in this Pages app.
I've gone ahead and setup my basic Pages repo where I have a

/site

/site

directory where I keep my frontend and is what is built when I run

npm run build

npm run build

to the

/dist

/dist

directory.
And I have my

/functions

/functions

directory which is of course where I am storing my backend API.
I am wondering if I should use a

/sql

/sql

directory to house the SQL and migrations?
Or should this be kept in a different repo?

Main question - how should I be structuring my Pages repo and use/include D1 migrations?

I've been seeing a lot of exceptions from my worker, all caused by the generic error message "D1_ERROR: Error: Error 9000: something went wrong". It seems to come and go, but when it happens more than half of my traffic ends with exceptions.

This doesn't seem to be input-related, as I can run the worker with identical inputs later on and it works. (This is a very simple app, all it really does is take GET values and save them).

Any suggestions on what I can do to troubleshoot this?

Adi•1/29/24, 5:39 AM

Hey all, wanted some help in understanding the metrics I'm seeing on my D1 database.
There is always an inconsistency in the write queries vs the rows written.
E.g over the last 24 hours There has been 1 write query but 6.47k rows written? Trying to work out how that happens.
I initially thought maybe it's index rebalancing, but that doesn't make sense because the underlying data doesn't change (only 1 write query).

Patrick M•1/30/24, 3:22 AM

I was having trouble recreating a table in a migration since

pragma foreign_keys=0

pragma foreign_keys=0

does not work in D1’s automatic transactions. I found some advice in this discord to use

pragma defer_foreign_keys=1

pragma defer_foreign_keys=1

which still didn’t fix my issue, just got a mysterious error message. Finally I stumbled on this hint: https://sqlite.org/forum/forumpost/825039816c3f0097 If you also reset

pragma defer_foreign_keys=0

pragma defer_foreign_keys=0

at the end of the script it will completely skip the foreign key checking. Feels a bit risky since even

pragma foreign_key_check

pragma foreign_key_check

is disabled in D1 and I don’t have a good way to confirm my data is still valid. But I’m glad I could at least apply my migration.

, but I'd prefer something more memorable. I'm also not sure if someone else who runs the setup locally would get the same file name.

I've tried with

--persist-local=db.sqlite

The docs mention that workers bound to a d1 database are always placed in a datacenter near the location of the db (https://developers.cloudflare.com/workers/configuration/smart-placement/#d1). Is this a limitation of the beta that will change once read replicas are a thing?

That same page indicates later that you can split up workers into front/backend workers that communicate using service bindings (https://developers.cloudflare.com/workers/configuration/smart-placement/#best-practices), suggesting one would be placed close to the user and the other close to the backend resource. This seems like it could help today if I could put the d1 bindings in the backend, but I'm a bit confused as to how this would work since the service binding docs seem to indicate that workers using service bindings are on the same machine?

Hello I need help with next-on-pages, I have a remote D1 database, and added it locally too. I did some migration with drizzle and everything worked fine and the data persisted locally to a sqlite file (say X). But when I follow the steps in next-on-pages/next-dev to use bindings inside next.js app, it does not use the file X, instead, it creates new file Y which has no migrations. Any solutions to his behavior? I tried to see if there is a way to make the next.js local binding use file X but I found nothing.

Hi, am new here. But there's something I need an understanding.

I have a Sveltekit project hosted on Cloudflare Pages. And now I want to add D1 as the database on this project.

I created the database using the D1 dashboard.

I want to follow the D1 docs, but it seems mostly it centered around Wrangler and Workers sort of.

How do I get started with D1 for a Pages project? Please any help or link to any doc? Thank you.
