Missing types for chrome.runtime.lastError and chrome.runtime.sendMessage

[piedrahitapablo]

Hi, I'm now migrating an extension to manifest v3 that was previously using @types/chrome, so far I have found 3 issues working with chrome-types:

1. Not really sure, but I think chrome.runtime.lastError is still a thing in manifest v3 and the types do not reflect its existence
2. For chrome.runtime.sendMessage there's a missing overload to call it only with a message and the callback, like chrome.runtime.sendMessage(message, cb)
3. Not sure if it's something intended but the types are missing adding the chrome property to the Window interface, if so, I think there should be some docs to show that

Thanks!

Hi, to add chrome types on your project, you may include it on tsconfig.json's compilerOptions like this
I agree with you on the runtime.sendMessage method missing the overloads.
I think @types/chrome has has them properly typed with Promises

{
  "compilerOptions": {
    "types": ["chrome-types"]
  }
}
