Initialization parameters

await init({
	runtime,
	storageName,
	databaseBinding
})

runtime =  Javascript runtime 
storageName = Alphanumeric storage name
databaseBinding = Cloudflare only D1 database binding env

Supported runtime :

• node use File System
• deno use File System need --allow-read --allow-write
• browser use IndexedDB
• bun use File System
• cloudflare workers use D1 Database docs example wrangler.toml

Write key-value pairs

await put(key,value)

The put() method returns a Promise that you should await on to verify a successful update, resolve to true or false

Read key-value pairs

await get(key)

The get() method returns a promise you can await on to get the value, resolve to the value or false

List keys

await list()

Use a list operation to view all the keys that live in a given storage, return a promise which resolves with an object consist of:

• keys = Array of keys
• complete = true if operation complete

Delete key-value pairs

await delete(key)

To delete a key-value pair, call the delete() method, resolve to true or false

Has key-value pairs

await has(key)

To check for the existence of a key, resolve to true or false

Clear storage

await clear()

To delete all key value pairs, resolve to true or false
