I linked my KV namespace with my worker, but when I try to use my variable name in my worker, it says it cannot find it

U

UnsmartOP•1/30/24, 2:46 AM

Can you give the actual error message and relevant code?

S

spaone•1/30/24, 2:51 AM

I have a KV namespace named KV, and the final line with KV.get("data") has the KV underlined red saying cannot find any KV:
addEventListener('fetch', event => {
event.respondWith(handleRequest(event.request));
});

async function handleRequest(request) {
if (request.method === 'POST' && request.url.endsWith('/submit-form')) {
const formData = await request.json();

await saveFormData(formData);

return new Response(null, {
status: 302,
headers: {
'Location': '/thankyou.html',
},
});
}

return new Response('Invalid request', { status: 400 });
}

async function saveFormData(formData) {

const data = await KV.get("data");

C

CosmosisT•1/30/24, 2:56 AM

Does const data = await KV.get("data", "json"); (dismiss this)
help?

S

spaone•1/30/24, 2:56 AM

no it doesn't

C

CosmosisT•1/30/24, 2:57 AM

How are you defining KV?

S

spaone•1/30/24, 2:59 AM

C

CosmosisT•1/30/24, 3:00 AM

Double check your configurations

C

CosmosisT•1/30/24, 3:01 AM

your code could be wrong/etc.

U

UnsmartOP•1/30/24, 3:04 AM

Oh a red underline just means you dont have types setup for it in ur code editor. Also you should upgrade to the more modern module worker format instead of service worker

S

spaone•1/30/24, 3:05 AM

sorry this is my first time using workers, how do I do both of those things?

U

UnsmartOP•1/30/24, 3:06 AM

Assuming your worker literally only does the one thing you sent I would just make a new worker from scratch. How did you make the worker you currently have?

S

spaone•1/30/24, 3:07 AM

i simply clicked create worker, and then linked it as a route to my site, and linked my kv namespace to it

U

UnsmartOP•1/30/24, 3:09 AM

hmm did you create it a long time ago? It should always create in the module format currently

S

spaone•1/30/24, 3:09 AM

no I didn't, how do I know if I'm in the module format or not

U

UnsmartOP•1/30/24, 3:09 AM

addEventListener

addEventListener

addEventListener

addEventListener means you are in service worker format

export default { fetch }

export default { fetch }

export default { fetch }

export default { fetch } means you are in module format

S

spaone•1/30/24, 3:10 AM

I made a new one and the default was export default,

U

UnsmartOP•1/30/24, 3:11 AM

Yeah using that one will be easier

S

spaone•1/30/24, 3:15 AM

if I put this in the body should it work? I am getting a KV is not defined error: const x = KV.get("data");

U

UnsmartOP•1/30/24, 3:18 AM

In the module format you use

env.KV

env.KV

env.KV

env.KV where

env

env

is the second parameter of the

fetch

fetch

function.

U

UnsmartOP•1/30/24, 3:20 AM

see this snippet from the cloudflare to-do list app example

Specifically this part of it:

export default {
  async fetch(request, env) {
    const setCache = (key, data) => env.EXAMPLE_TODOS.put(key, data);
    const getCache = key => env.EXAMPLE_TODOS.get(key);
  }
};

export default {
  async fetch(request, env) {
    const setCache = (key, data) => env.EXAMPLE_TODOS.put(key, data);
    const getCache = key => env.EXAMPLE_TODOS.get(key);
  }
};

export default {
  async fetch(request, env) {
    const setCache = (key, data) => env.EXAMPLE_TODOS.put(key, data);
    const getCache = key => env.EXAMPLE_TODOS.get(key);
  }
};

export default {
  async fetch(request, env) {
    const setCache = (key, data) => env.EXAMPLE_TODOS.put(key, data);
    const getCache = key => env.EXAMPLE_TODOS.get(key);
  }
};

S

spaone•1/30/24, 3:23 AM

okay thank you I think I have the namespace linked properly I appreciate it

S

spaone•1/30/24, 3:25 AM

if I have my worker linked to my site, and on my site I have a post to a /submit-form, which then routes to a /thankyou and this is all done on my site. Can I still use a worker that submits when a post is sent to submit-form from my site? Or will there be interference

U

UnsmartOP•1/30/24, 3:27 AM

you can yes, workers run before it makes a request to your origin and you can modify behavior of requests to the origin or even completely skip the origin and return a response in the worker

S

spaone•1/30/24, 3:34 AM

okay cool. what would be the best way to save data from a form using the worker and then reroute?

I never thought that Cloudflare's Workers could be so useful in breaking through network censorship and protecting my privacy.

Kitodi•1/30/24, 8:31 AM

Is there a way to handle the timeout when using TCP sockets? When this is called and the server has no response, the Cloudflare Worker get stuck at the

read()

read()

read()

read() function. Not confirmed in production, it might also get stuck there.

import { connect } from 'cloudflare:sockets'

connect(...).socket.readable.getReader().read()

import { connect } from 'cloudflare:sockets'

connect(...).socket.readable.getReader().read()

import { connect } from 'cloudflare:sockets'

connect(...).socket.readable.getReader().read()

import { connect } from 'cloudflare:sockets'

I want to enable sass for an Worker API hosted on api.myapp.io.

I want to redirect my customer

api.customerapp.me

api.customerapp.me

api.customerapp.me

api.customerapp.me to my hosted worker

api.myapp.io

api.myapp.io

api.myapp.io

api.myapp.io

I've tried the following settings with no luck (Error code 522)

DNS Settings:

Type Name Content Proxy Status
AAAA api.myapp.io 100:: Proxied

Worker Routes:

Route Worker
api.myapp.io/ dh-api

SSL/TLS -> Custom Hostnames

Fallback Origin -> api.myapp.io

Custom Hostnames:

Custom Hostname Certificate status Expires on Hostname status Origin server
api.customerapp.me Active 2024-04-29 Active Default

I've added the generated TXT to my customer's dns setting.

You're missing the wildcard route as per the docs you linked

C

Chaika•1/30/24, 2:17 PM

Worker Routes see the request as coming from

api.customerapp.me

api.customerapp.me

api.customerapp.me

api.customerapp.me, so it's not going to match

api.myapp.io

api.myapp.io

api.myapp.io

api.myapp.io, hence the need for the wildcard

Shadowfax•1/30/24, 2:20 PM

I can't select / for a wildcard because I've multiple workers on the zone . e.g. api.myapp.io, api2.myapp.io. If I set the wildcard it routes everything to the api.myapp.io. any workaround for that?

C

Chaika•1/30/24, 2:21 PM

If those other workers are worker routes, the wildcard shouldn't apply because the most specific rule takes precedence

C

Chaika•1/30/24, 2:22 PM

otherwise you could create a

*.<zonename>.com/*

*.<zonename>.com/*

*.<zonename>.com/*

*.<zonename>.com/*, service: none route as suggested in that post to prevent it from applying to your own zone, or I believe you could just create a route per customer domain if you only plan on having a few

Shadowfax•1/30/24, 3:38 PM

The second option seems to work. But I need to add them programmatically for each customer willing to have a custom hostname. I found the API doc to add a worker route https://developers.cloudflare.com/api/operations/worker-routes-create-route. That should work. But I was wondering if it is the right solution.

C

Chaika•1/30/24, 3:41 PM

it's not really the right solution no, there's a limit of 1000 routes or so and if you get too many they slow down overall routing (each one has to be evaluated)

C

Chaika•1/30/24, 3:42 PM

the right solution would just be a wildcard like they suggest, then using a single wildcard to exclude everything on your domain

C

Chaika•1/30/24, 3:42 PM

it is a bit messy though and potentially confusing for you in the future, you could buy a second domain dedicated to your customers/cf for saas to better isolate it

Is this the correct way to have a write-once r2 put?

const r2_put_prom = c.env.test.put(`test.json`, JSON.stringify({}, null, 2), {
    httpMetadata: {
        contentType: "application/json; charset=utf-8"
    },
    customMetadata: {
        "sup": "hey"
    },
    onlyIf: new Headers({
        "If-Unmodified-Since": new Date(0).toUTCString()
    })
})

const r2_put_prom = c.env.test.put(`test.json`, JSON.stringify({}, null, 2), {
