We have a fixture used for DOs which you could copy: https://github.com/cloudflare/wrangler2/tree/main/fixtures/external-durable-objects-app

@WalshyDev Will this be released any time soon?

The documentation has been out of date for a while:

• https://developers.cloudflare.com/pages/platform/functions/bindings/#interact-with-your-service-binding-locally
• [Pages] Functions docs rewrite cloudflare-docs#5015

[JorritSalverda]

Would be brilliant if this gets released. Any ETA?

Is there any quick work-around for being able to bind a worker to a page application locally in the mean time?

Is there any quick work-around for being able to bind a worker to a page application locally in the mean time?

Could you move the shared logic that you want to service bind to into a separate Worker of its own, then service bind to it from the Pages project and from any other Workers where it is needed?

[GregBrimble]

Quick skim looks good, but need to go over it in a bit more detail later.

[GregBrimble]

Looks good, thanks for being patient and making all those refinements!
