Cyb3r-Jak3•12/30/23, 4:28 PM

For D1 with pages, you can do pretty much all the same dev locally as workers but use remote dev because pages doesn't support that. I use the standard wrangler file in my pages project for interacting with bindings. Just have to remember to use the dashboard to apply bindings

No, they are two separate databases. You have two run migrations in both

Once with the

Yes. There is the REST API but it is rate limited so better making your own with the worker

Does anyone know of any project that is attempting local SQLite replication that would work with D1? For instance, https://github.com/vlcn-io/cr-sqlite and https://electric-sql.com/ are both really cool but not inherently compatible with D1

<Alterion.Dev>•1/1/24, 4:50 PM

I'm a little curious why D1 doesn't have a

.get()

.get()

method to retrieve a single row in the db. Not that it's the end of the world that I have to do .all()[0] but it seems... weird, that I can't just do

db.prepare(blah).bind(somevar).get()

db.prepare(blah).bind(somevar).get()

db.prepare(blah).bind(somevar).get()

db.prepare(blah).bind(somevar).get() ?

<

<Alterion.Dev>•1/1/24, 4:52 PM

like,

const table = this.#db
  .prepare(
    "SELECT count(*) FROM sqlite_master WHERE type='table' AND name = ?;",
  ).bind(this.#name).get();

// vs
const table = this.#db
  .prepare(
    "SELECT count(*) FROM sqlite_master WHERE type='table' AND name = ?;",
  ).bind(this.#name).all()[0];

const table = this.#db
  .prepare(
    "SELECT count(*) FROM sqlite_master WHERE type='table' AND name = ?;",
  ).bind(this.#name).get();

// vs
const table = this.#db
  .prepare(
    "SELECT count(*) FROM sqlite_master WHERE type='table' AND name = ?;",
  ).bind(this.#name).all()[0];

const table = this.#db
  .prepare(
    "SELECT count(*) FROM sqlite_master WHERE type='table' AND name = ?;",
  ).bind(this.#name).get();

// vs
const table = this.#db
  .prepare(
    "SELECT count(*) FROM sqlite_master WHERE type='table' AND name = ?;",

Making a wow classic armory appliation via pages: https://atlasforge.gg/wow-classic/armory/us/crusader-strike/Rhyis and want to start storing basic data about characters in a D1 DB, so I can show level and item level leaderboards.

Hmm that part I'm not sure of as I don't use Pages functions... there is a PATCH REST API to alter worker bindings, maybe similar exists for pages?

You can use the REST API to both create the D1 databases and bind them to a pages project

Kkian `.first()`

<

<Alterion.Dev>•1/1/24, 10:28 PM

That's... interesting. am I just used to all the other libraries just using .get() ? Any specific technical reason this is different here, along with the .bind() being required?

<

<Alterion.Dev>•1/1/24, 10:32 PM

no I mean, you need to do db.prepare(query).bind(params).all() , for example. But other sqlite modules basically all do

db.prepare(query).all(params)

db.prepare(query).all(params)

.

<

<Alterion.Dev>•1/1/24, 10:33 PM

The fact that it's

.first()

.first()

instead of

.get()

.get()

is a separate "why would this be different" issue. Like, I don't want to sound rude, it just feels like there's no legitimate reason for these things to not use a more standardised sqlite API

K

kian•1/1/24, 10:37 PM

db.prepare(query).all()

db.prepare(query).all()

is valid.

kian•1/1/24, 10:37 PM

Oh, I see what you mean.

<Alterion.Dev>•1/1/24, 11:13 PM

I will certainly not argue that returning the first column of a result is wrong - absolutely not!

<

<Alterion.Dev>•1/1/24, 11:13 PM

My question is why doesn't D1 follow the known convention of all the other npm sqlite wrappers that I know of, essentially

<

<Alterion.Dev>•1/1/24, 11:14 PM

having first() and get() would make this easier to move existing code to D1

<

<Alterion.Dev>•1/1/24, 11:15 PM

And removing .bind() intermediary in order to directly support binding in the execution call (run(), all(), get(), exec()) would also make it a lot easier
