get function returns JsonValue that needs to be re-cast every time about kvs

[azu]

What type is the list?

KVS treat the value as JSON value.
It means that KVS apply JSON.stringify/JSON.parse to saving/loading value.

(async () => {
    const { kvsLocalStorage } = await import("https://unpkg.com/@kvs/[email protected]?module");
    const storage = await kvsLocalStorage({
        name: "database-name",
        version: 1
    });
    const list = [1, 2, 3];
    await storage.set("list", list);
    const savedList = await storage.get("list");
    console.log(savedList); //  [1, 2, 3]
})();

📝 JSON-able value is string, number, boolean, null, object, array.
KVS can not serialize Map or Set automatically.

export type JsonValue = string | number | boolean | null | JsonObject | JsonArray;

Hello,

Thanks for the quick reply!

The signature was misleading me and my error was elsewhere, I solved it by the time you replied but what I meant was simply casting it to string[]

I just realized the error is elsewhere and "as string[]" works perfectly.

This can be closed whenever you feel satisfied!

Best regards

KVS support StorageSchema type as generics.
https://github.com/azu/kvs#typescript

type StorageSchema = {
    // key is string
    // value is string[]
    [index:string]: string[]
};
const storage = await kvsIndexedDB<StorageSchema>({
    name: databaseName,
    version: 1
});
await storage.set("a1", ["string"]); 
const a1 = await storage.get("a1");

I do not understand all, but if you provice reproduce code, I can investigate it.
Feel free to reopen if kvs's type is wrong.
