function Deno.openKv
Unstable
openKv(path?: string): Promise<Kv>
Open a new [`Deno.Kv`](../././~/Deno.Kv) connection to persist data.
When a path is provided, the database will be persisted to disk at that
path. Read and write access to the file is required.
When no path is provided, the database will be opened in a default path for
the current script. This location is persistent across script runs and is
keyed on the origin storage key (the same key that is used to determine
`localStorage` persistence). More information about the origin storage key
can be found in the Deno Manual.
