In my case it's not a monorepo. If I would have a monorepo, I would probably have tried as well what you did.

J

johtsoOP•4/6/24, 9:32 PM

the docs also say to do something like

interface Env {
  MY_SERVICE: Service<MyService>;
}

interface Env {
  MY_SERVICE: Service<MyService>;
}

interface Env {
  MY_SERVICE: Service<MyService>;
}

interface Env {
  MY_SERVICE: Service<MyService>;
}

J

johtsoOP•4/6/24, 9:32 PM

ah right, you don't have the code together

johtsoOP•4/6/24, 9:32 PM

makes sense

I basically did what's written in the blog post under "What about type safety"
https://blog.cloudflare.com/javascript-native-rpc

Hmm, I just read it again and it sounds like import should work as well:

You might do this by defining the interface in a separate shared TypeScript file, or by extracting a .d.ts type declaration file from your server code...

The Cloudflare Blog

We've added JavaScript-native RPC to Cloudflare Workers

Cloudflare Workers now features a built-in RPC (Remote Procedure Call) system for use in Worker-to-Worker and Worker-to-Durable Object communication, with absolutely minimal boilerplate. We've designed an RPC system so expressive that calling a remote service can feel like using a library.

johtsoOP•4/6/24, 9:58 PM

Yeah, even ignoring typescript, I keep getting "TypeError: Illegal invocation" when trying to use the service

J

johtsoOP•4/6/24, 9:58 PM

my wrangler has something like this

[[services]]
binding = "PDFPARSER_SERVICE"
service = "pdfparser"

[[services]]
binding = "PDFPARSER_SERVICE"
service = "pdfparser"

[[services]]
binding = "PDFPARSER_SERVICE"
service = "pdfparser"

service = "pdfparser"

J

johtsoOP•4/6/24, 9:58 PM

which I thought was all you needed to do

J

James•4/6/24, 9:59 PM

hmm. What's your compat date/flags?

J

johtsoOP•4/6/24, 9:59 PM

compatibility_date = "2024-04-06"
compatibility_flags = [ "nodejs_compat" ]

compatibility_date = "2024-04-06"
compatibility_flags = [ "nodejs_compat" ]

compatibility_date = "2024-04-06"
compatibility_flags = [ "nodejs_compat" ]

compatibility_date = "2024-04-06"

J

James•4/6/24, 9:59 PM

okay yeah that should be totally fine

pdfparser is the name of my other worker. it exports the

J

James•4/6/24, 10:02 PM

I'm not sure it is. But if it is, your code should be fine. Have you tried it? Did you experience any issue?

J

johtsoOP•4/6/24, 10:03 PM

um.. so I deleted all my
.wrangler
.wrangler
.wrangler
.wrangler directories and restarted my workers and now it's working?

S

safah222•4/6/24, 10:03 PM

the worker didnt gave any error , how ever its not detecting any type of bots

S

safah222•4/6/24, 10:03 PM

all of the bots still not triggered by my code , maybe because I am writing the code in inccorect way

node_compat

node_compat as a top-level option is legacy and should be avoided whenever possible.

nodejs_compat as a compat flag is good and won't incur any kind of performance issues

Hi, what would you recommend for importing a 1GB txt file from a cron to populate my D1 database? So that it doesn't exceed the resource limits.

J

johtsoOP•4/6/24, 10:04 PM

oh wait no ignore that.. the ports just got swapped so I was hitting the other worker.. still not working

JJames Did you try giving the entrypoint a name with `entrypoint`?

J

johtsoOP•4/6/24, 10:07 PM

I did try exporting it with a name, I'll give that another try though

J

@James I get this message when running the dev server
