Do you have code to reproduce it?

I'll see what I can do, but the issue seems to appear primarily when cross-region is involved

Not really sure what you mean by a config for an api endpoint

Hello, I’m Allie!•1/25/23, 9:14 AM

How do you want config to be updated(HTTP endpoint, changes via git, etc.)? The fastest way to update config values(have them available everywhere) would be to publish a new Worker, but it is also slow(contradictory, I know) in the sense that updating a Worker in every datacenter may take up to 30 seconds(depending on whether you are on paid too).

Nnp I suppose thats an option to have the config embedded in the code, but its reall...

You could do that too

Hey! KV is supposed to be a single key value pair right?

Or could I store json in the value too?

Assuming I don't want to json.stringify my object

E

Erisa•1/28/23, 2:22 PM

you need to stringify to write it

E

Erisa•1/28/23, 2:23 PM

when reading you can use

.get(key, { type: "json" });

.get(key, { type: "json" });

.get(key, { type: "json" });

.get(key, { type: "json" }); to return the object directly

Hi all. I was wondering if you can use KV without using it via the workers.

J

James•1/28/23, 7:32 PM

You can interact with KV over the API, yes: https://api.cloudflare.com/#workers-kv-namespace-properties

I have a KV namespace with values like:

 car:golf1.4 -> {brand: VW, power:...... } 
  car:F150   ->  {brand: Ford, power: ...}

 car:golf1.4 -> {brand: VW, power:...... } 
  car:F150   ->  {brand: Ford, power: ...}

 car:golf1.4 -> {brand: VW, power:...... } 
  car:F150   ->  {brand: Ford, power: ...}

 car:golf1.4 -> {brand: VW, power:...... } 
  car:F150   ->  {brand: Ford, power: ...}

I'd like to be able to select by brand and randomly. What's the best approach?
To use an additional KV as index

    brand:VW - >  [golf1.4, ...]  
   brand:Ford -> [F150, ...]

    brand:VW - >  [golf1.4, ...]  
   brand:Ford -> [F150, ...]

    brand:VW - >  [golf1.4, ...]  
   brand:Ford -> [F150, ...]

    brand:VW - >  [golf1.4, ...]  
   brand:Ford -> [F150, ...]

Or to insert the brand in the key and then use the

list

list

method:

  car:VW:golf1.4  ->   ..
  car:Ford:F150  ->

  car:VW:golf1.4  ->   ..
  car:Ford:F150  ->

  car:VW:golf1.4  ->   ..
  car:Ford:F150  ->

  car:VW:golf1.4  ->   ..
  car:Ford:F150  ->

But this is more expensive and cannot randomize them, right?

Rrodrigo I have a KV namespace with values like: ``` car:golf1.4 -> {brand: VW, power:...

You can list by prefix and then you can randomize the results on the client side fairly easily?

Specifically, just choose a random integer between 0 and

length

length

length

length of your list -> then access that array item directly.

let idx = Math.floor(Math.random() * results.keys.length)
# where results is the array returned from list()
let val = results.keys[idx]

let idx = Math.floor(Math.random() * results.keys.length)
# where results is the array returned from list()
let val = results.keys[idx]

let idx = Math.floor(Math.random() * results.keys.length)
# where results is the array returned from list()
let val = results.keys[idx]

let idx = Math.floor(Math.random() * results.keys.length)
# where results is the array returned from list()
let val = results.keys[idx]

Ok, it makes sense.
Btw, I've checked the

flareutils

flareutils

flareutils

flareutils library and I see there's also a

list

list

method combining cache and kv.
https://github.com/helloimalastair/flareutils/blob/0aa471d/src/BetterKV.ts#L295
But I see it uses this URL

cacheKey = new URL("https://list.better.kv");

cacheKey = new URL("https://list.better.kv");

cacheKey = new URL("https://list.better.kv");

cacheKey = new URL("https://list.better.kv");
Do you know what this URL is about? Am I supposed to get the same results as using the KV alone? Thx

Hello, I’m Allie!•2/2/23, 11:11 AM

That url is just there to uniquely identify the list operation in the cache. You can call it whatever you want, as long as it is unique

You won't be able to run something like

axios

axios

on Workers, which is sounds like you're trying to do

J

James•2/3/23, 12:47 AM

You'll need to use

fetch

fetch

for HTTP calls in Workers. But in Workers, you don't need to do that You can use a KV binding: https://developers.cloudflare.com/workers/runtime-apis/kv/#kv-bindings

uses Node's

module, which doesn't exist in Workers. Workers run JavaScript via V8, but not Node.js

I'm not sure if there's any specific literature on KV + TS, but it's all built into

@cloudflare/workers-types

@cloudflare/workers-types

@cloudflare/workers-types. There's a

KVNamespace type which you can assign to

env.KV_BINDING

env.KV_BINDING

env.KV_BINDING

env.KV_BINDING or similar, which should work well

is the future anyway especially now it's in Node!

U

Unsmart•2/3/23, 1:11 AM

its not a default of the runtime

W

Walshy•2/3/23, 1:24 AM

Axios a few years ago was great, these days

fetch

fetch

is the standard within browsers and runtimes. Having that consistency is really good and it's native!

James•2/3/23, 2:31 AM

Can you provide a reproduction? A link to your repo or something and the commands you’re running would be good

J

James•2/3/23, 2:34 AM

Sure. It’d probably make sense to move to #workers-help to condense this all
