You mean like multiple wrangler dev calls?

Yup

i see! so my repo directory structure should be like:

package.json
src/
public/
durable_objects/
—— package.json
—— wrangler.toml
—— src/

package.json
src/
public/
durable_objects/
—— package.json
—— wrangler.toml
—— src/

essentially a module (with package.json + wrangler.toml inside a subdirectory of my Pages repo) ah, figured it out!

yep! i was able to get a worker in the pages deploy to bind to a durable object, both locally and remotely

haha, that's what i did too, using the discord search function scoped to the #durable-objects channel 🙂 I think this is demonstrable proof that DO and DO+Pages needs better documentation...

Yes, and no, not necessarily Basically, the Worker is only needed to publish the DO class. It doesn't need any of the normal Worker logic. It could be as simple as

export class SomeDOClass {
  // ...
}

export class SomeDOClass {
  // ...
}

Notice the lack of export default This also means that you can bind directly to the DO from your Functions, and not have to invoke the Worker itself at all

What if you do

name = "langchain-storage"
compatibility_date = "2023-05-04"
main = "./src/index.ts"
no_bundle = true

[durable_objects]
bindings = [{name = "LANGCHAIN", class_name = "LangChainStorage"}]

[[migrations]]
tag = "v1"
new_classes = ["LangChainStorage"]

name = "langchain-storage"
compatibility_date = "2023-05-04"
main = "./src/index.ts"
no_bundle = true

[durable_objects]
bindings = [{name = "LANGCHAIN", class_name = "LangChainStorage"}]

[[migrations]]
tag = "v1"
new_classes = ["LangChainStorage"]

Oh wait Bundle it first, then change the main Or just add an

export default {}

export default {}

to the file
