Hi everyone, I'm trying to access local storage from web-extension:

StorageSettings(
                delegate = js("self.chrome.storage.local") as? Storage ?: js("self.localStorage") as? Storage ?: error("Could not create chrome.storage.local"),
            )

but so far I get ERROR ReferenceError: Storage is not defined , any recommendation what I might be doing wrong?

local storage can be accessed with

external val localStorage: Storage

Try taking a look at the Kotlin Wrappers project - it provides common implementations, including localStorage

https://github.com/JetBrains/kotlin-wrappers/blob/b3386a80419d76e48f1a35e5ff7afad746e91faf/kotlin-browser/src/jsMain/generated/web/storage/localStorage.val.kt#L3

I can't see an equivalent for chrome.storage.local, but you can probably use Kotlin Wrappers for inspiration

do you know what this code is generated from? I.e. the interface for chrome.storage.local is more complex, can't work it out to fit.

Another way to do it is just rely on js() dynamic code usage

ot, I think I made some progress with this interface:

public external interface ChromeStorage {
    fun set(items: dynamic): Promise<Unit>
    fun get(key: String): Promise<dynamic>
    fun remove(key: String): Promise<Unit>
    fun clear(): Promise<Unit>
}
