kv-toolbox

A set of tools for working with Deno KV.

Blob

A set of APIs for storing arbitrarily sized blobs in Deno KV. Currently Deno KV has a limit of key values being 64k. The set() function breaks down a blob into chunks and manages sub-keys to store the complete value. The get() function reverses that process.

set()

Similar to Deno.Kv.prototype.set(), in that it stores a blob value with an associated key. In order to deal with the size limitations of values, set() will transparently chunk up the blob into parts that can be handled by Deno KV.

The blob can be a byte ReadableStream or array buffer like.

get()

Similar to Deno.Kv.prototype.get(), in that it retrieves a blob value based on the provided key. If a previous blob value has been set with set(), it will be retrieved.

By default the value is resolved as a Uint8Array but if the option stream is set to true, then a byte ReadableStream is provided to read out the blob.

remove()

Similar to Deno.Kv.prototype.delete(), in that it deletes a blob key and value form the data store. If a blob value isn't stored for the given key, it resolves in a noop.

Keys

APIs for dealing with Deno KV keys.

keys()

Similar to Deno.Kv.prototype.list(), in that is takes a selector, but instead of returning an async iterator of matched values, it resolves with an array of matching keys.

unique()

Resolves with an array of unique sub keys/prefixes for the provided prefix.

This is useful when storing keys and values in a hierarchical/tree view, where you are retrieving a list and you want to know all the unique descendents of a key in order to be able to enumerate them.
