next-auth doesn't have to be out of workers btw https://github.com/cloudflare/next-on-pages/tree/main/packages/next-on-pages

hi, what's your typical latency in d1-beta?

K

kian•1/8/24, 2:55 PM

Hovers around 40-50ms personally, sometimes as low as 20ms.

RraRaRa Hi everyone. Is it possible to use D1 outside of Workers? E.g. if I run NextJS i...

You can write your own Worker that exposes an API to NextJS: https://github.com/elithrar/http-api-d1-example

Max (@rozenmd)•1/8/24, 5:01 PM

using the public API directly also works, but isn't as performant

I am trying to add an element to an array

UPDATE daily SET schedule = json_insert(schedule,$[json_array_length(schedule)],'16.00') WHERE day = 1

UPDATE daily SET schedule = json_insert(schedule,$[json_array_length(schedule)],'16.00') WHERE day = 1

but got unrecognized token

W

Will•1/9/24, 6:51 AM

how can I insert the element without knowing the array length?

W

Will•1/9/24, 6:54 AM

I have tried to use $[-1] , but it doesn't work

W

Will•1/9/24, 6:59 AM

solved it

W

Will•1/9/24, 6:59 AM

UPDATE daily SET schedule = json_insert(schedule,'$[' || json_array_length(schedule) || ']','16.00') WHERE day = 1

UPDATE daily SET schedule = json_insert(schedule,'$[' || json_array_length(schedule) || ']','16.00') WHERE day = 1

Hi, when using D1, would it make sense to use Cache-Aside pattern with KV?
Cache-Aside pattern:
"Load data on demand into a cache from a data store. This can improve performance and also helps to maintain consistency between data held in the cache and data in the underlying data store."

Does D1 have any implementation for Levenshtein? (like postgres does with fuzzystrmatch). Thanks

You can append to an array using ‘$[#]’ to denote the insert position

if i have an array of primary keys, how do i search using IN?
will this work? or do i need to format the array to a comma delimited string?

            const { results: usersFromUserIds } = await this.env.DB.prepare(

            const { results: usersFromUserIds } = await this.env.DB.prepare(

            const { results: usersFromUserIds } = await this.env.DB.prepare(

            const { results: usersFromUserIds } = await this.env.DB.prepare(

SELECT *
FROM user
WHERE _id IN (?1)


            )
                .bind(uniqueUserIds)
                .all()


            )
                .bind(uniqueUserIds)

Trying to understand how local D1 runs a bit and I'm a bit confused. To run D1 locally it seems you have two options:

as part of
```
wranger dev
```
wranger dev
```
wranger dev
```
wranger dev
using miniflare

I'm trying to find a way to have my local D1 instance run it, but be able to query it from a separate process. I thought I could start it using #1, and connect to it from another process using the D1 Client via miniflare, but this doesn't seem to work.

How can I achieve this?

K

kian•1/9/24, 9:12 PM

D1 is just SQLite built into the Workers runtime, and that's what

wrangler dev

wrangler dev

is - running a Worker.

K

kian•1/9/24, 9:12 PM

Miniflare uses the runtime as well.

A

ALECKS•1/9/24, 9:34 PM

Yeah i just wasn't sure how to connect to a running D1 instance from another node process. But I figured it out. You can specific the DB1 database details in the miniflare config object. This worked for me, reference if others need it:

  const mf = new Miniflare({
    modules: true,
    script: "",
    d1Persist: "PATH_TO_PROJECT/.wrangler/state/v3/d1",
    d1Databases: { DB: "DB_ID_HERE" },
  });
  const db = await mf.getD1Database("DB");
  const out = await db.prepare("SELECT name FROM sqlite_schema").raw();

  const mf = new Miniflare({
    modules: true,
    script: "",
    d1Persist: "PATH_TO_PROJECT/.wrangler/state/v3/d1",
    d1Databases: { DB: "DB_ID_HERE" },
  });
  const db = await mf.getD1Database("DB");
  const out = await db.prepare("SELECT name FROM sqlite_schema").raw();

  const mf = new Miniflare({
    modules: true,
    script: "",
    d1Persist: "PATH_TO_PROJECT/.wrangler/state/v3/d1",
    d1Databases: { DB: "DB_ID_HERE" },
  });
  const db = await mf.getD1Database("DB");
  const out = await db.prepare("SELECT name FROM sqlite_schema").raw();

  const mf = new Miniflare({
    modules: true,
    script: "",
    d1Persist: "PATH_TO_PROJECT/.wrangler/state/v3/d1",
    d1Databases: { DB: "DB_ID_HERE" },
  });
  const db = await mf.getD1Database("DB");
  const out = await db.prepare("SELECT name FROM sqlite_schema").raw();

What's the difference between the local db and the preview db (

preview_database_id

preview_database_id

in wrangler.toml)?

implying only professional_id is used as the index

W

while business_id is indexed too

and it's the left most column

is this an expected behavior?
