When should kv.close() be called?

[brettchalupa]

I've been digging into using Deno KV, and I was wondering how others are approaching interacting with the KV store and closing the connection.

Do you call:

const kv = await Deno.openKv();

Multiple times throughout your application or do you export your kv once and then access it through an import in your code?

I see the Todo Showcase app exports the kv as db. And I can't find any reference to closing it.

Or do you open it and close it within a given function? Example:

export async function verifyPassword(
  username: string,
  password: string,
): Promise<boolean> {
  const kv = await Deno.openKv();
  const userRes = await kv.get<User>(["users", username]);
  if (!userRes.value) {
    throw new Error("user does not exist");
  }
  kv.close();

  const user = userRes.value;
  return await verify(user.passwordHash, password);
}

Thanks!
