Values
Deno KV supports any JavaScript built-in types that are supported via structured clone. The values are limited to 64k in their stored format. kview via kv-toolbox add support for three blob types. These have no hard size limit.
Important
Deno KV supports storing any JavaScript values that are cloneable, but currently doesn't support storing Web API types that are cloneable (See: denoland/deno#12067).
The support table is seen below:
