Great! That would help a lot. One for deployments, but two also for local dev & mocking of bindings.

(aswell integration with other build tools)

Adam•9/22/23, 9:38 PM

some bindings are supported today for local Pages dev in

wrangler.toml

wrangler.toml

like D1, but that's only for local dev

alex (he/him)OP•9/22/23, 9:51 PM

Cool! Yeah looking forward for full support. So we don't have to switch between dashboard & config file. Thx!

Cyb3r-Jak3•9/24/23, 4:54 PM

You can use the same command that you would with remote but add

—local

—local

GG wrangler dev —local?

Cyb3r-Jak3•9/24/23, 4:57 PM

Do you want to add values to a local kv instance or run wrangler in dev mode?

Cyb3r-Jak3•9/24/23, 5:00 PM

Not at my computer but it should be something like

wrangler kv:key put <name> <value> —binding <name of binding> —local

wrangler kv:key put <name> <value> —binding <name of binding> —local

Cyb3r-Jak3•9/24/23, 5:01 PM

I might have gotten the

kv:key

kv:key

part wrong but if you do

wrangler —help

wrangler —help

then it should show the right command

Cyb3r-Jak3•9/24/23, 5:06 PM

I don’t believe it matters. Wrangler should auto create it if it doesn’t exist

That should only happen when youre using

--live-reload

--live-reload

Erisa•9/26/23, 12:26 AM

try explicit

--live-reload false

--live-reload false

and if that doesnt work, whats your wrangler version and workers/pages setup?

EErisa That should only happen when youre using `--live-reload`

kingmesal•9/26/23, 1:33 AM

This was as of 3.8.0 .. couldn't test in 3.9.0 because function bindings were not working.

Hello! After updating wrangler from v2 to v3 our

yarn wrangler dev

yarn wrangler dev

no longer works and crashes with

~/.yarn/cache/wrangler-npm-3.9.0-e05cb2862a-b0e6c7ca1f.zip/node_modules/wrangler/wrangler-dist/cli.js:30947
            throw a;
            ^

TypeError: Class extends value undefined is not a constructor or null

~/.yarn/cache/wrangler-npm-3.9.0-e05cb2862a-b0e6c7ca1f.zip/node_modules/wrangler/wrangler-dist/cli.js:30947
            throw a;
            ^

TypeError: Class extends value undefined is not a constructor or null

One suggestion could be that wrangler v3 is not friends with PNP. So then, for some reason, running

npx wrangler dev

npx wrangler dev

(after package manager installs it outside our project into home folder npm/npx cache), it seems to work but KV writes seem to crash with cryptic errors such as

Any idea what might be wrong with the move to v3?

Is there any way to tell wrangler to use a specific workerd executable?

Running

wrangler dev

wrangler dev

on a project with a KV binding uses the

preview_id

preview_id

from

wrangler.toml

wrangler.toml

. However, reading a value always returns null.

From what I understand, preview namespaces are not local, I checked on the dashboard and the value exists for the given key.

Are preview namespaces what I am supposed to use locally?
If not, is there something really local and how do I run that (I checked the docs but haven't found anything)

I tried that and then it hangs

christianklotz•9/27/23, 7:42 PM

Something to do with the wrangler/miniflare dependencies perhaps?

Cyb3r-Jak3•9/27/23, 7:54 PM

That’s weird never had it hang before.

Adam•9/27/23, 7:56 PM

It shouldn't hang. If you're running into a consistent issue, please file a bug so we can take a closer look: https://github.com/cloudflare/workers-sdk/issues/new?assignees=&labels=bug&projects=&template=bug-template.yaml&title=%F0%9F%90%9B+BUG%3A

christianklotz•9/27/23, 8:01 PM

For context, yesterday it was complaining about

better-sqlite3

better-sqlite3

not being the right binary (don't remember the detail), so I did

npm rebuild better-sqlite3 --update-binary

npm rebuild better-sqlite3 --update-binary

It's no longer complaining but maybe that caused some side effect? However, just installed all dependencies again, still hangs.

AAdam It shouldn't hang. If you're running into a consistent issue, please file a bug ...

christianklotz•9/27/23, 8:02 PM

Great, thanks. Will file unless the binary thing sounds like some obvious issue

Cyb3r-Jak3•9/27/23, 8:04 PM

I believe better-sqlite was removed because workerd now has it native.

Follow up: turns out this is a Node issue.

For some reason it doesn't work with 20.5.1 but seems to play well with 20.7.0. Could possibly be related to me using NPM workspaces

wrangler 3.8.0 : D1 uses

/.wrangler/state/v3/d1/{UUID}/db.sqlite

/.wrangler/state/v3/d1/{UUID}/db.sqlite

for its sqlite storage

wrangler 3.9.0+ : D1 uses

/.wrangler/state/v3/d1/miniflare-D1DatabaseObject/{UUID}.sqlite

/.wrangler/state/v3/d1/miniflare-D1DatabaseObject/{UUID}.sqlite

<-- the UUID here, I have NO idea where it comes from and it is not in my wrangler.toml

It migrates my data from the old location to the new and destroys the old (NOT cool!)

.... all that aside ... I have 2 questions...

What exactly does that UUID reference?
Was there a reason for this restructuring?
