List keys via for-await-of about workers-types

[GregBrimble]

Hi @CrockAgile ,

I'm not affiliated with this workers-types, but in my own projects, I've been using something like this, which might be of use to you:

async function* listAll(namespace, options) {
  let cursor;
  let hasNextPage = true;
  while (hasNextPage) {
    const results = await namespace.list({ ...options, cursor })
    const { keys: queue } = results
    hasNextPage = !results.list_complete

    while (queue.length > 0) {
      const key = queue.shift()
      if (key !== undefined) yield key
    }
  }
}

Which then allows you to use a for await...of loop in an async function:

for await (const key of listAll(NAMESPACE, {"prefix": "user:1:" })) {
  // use key
  // e.g. await NAMESPACE.get(key.name)
}

As an unrelated aside, your key generation looks very similar to that of my own project's kv-orm. I'd be very interested to hear about what you're working on, if kv-orm could be of any use, and/or if I could learn anything from what you're working on. My email is in my profile. Please get in touch!

Thanks for the example @GregBrimble ! Glad to know I am not the only one hitting this use case. I'm not working on anything interesting. I am building a minimal app just to learn my way around CF workers. I'll give kv-orm a look since it seems to be a more full feature version of the hacky data model I am using for this small test project.
