<script src="https://cdn.jsdelivr.net/npm/kv-storage@0.0.7/dist/umd/kv-storage.js"></script>

Initialization

NPM

//Node & Bun CommonJS import style
const {KVStorage} = require('kv-storage')

//Node, Browser, Deno, Bun & Cloudflare ES Modules import style
import {KVStorage} from 'kv-storage'

//Deno import style
import {KVStorage} from 'npm:kv-storage@0.0.7'

//Node, Browser, Deno & Bun Initialization
const db = await KVStorage({
	runtime:'node', //node | browser | deno | bun
	storageName:'storage'
})

//Cloudflare Initialization
const db = await KVStorage({
	runtime:'cloudflare',
	storageName:'storage', //Cloudflare D1 database name
	databaseBinding:env.D1 //Cloudflare D1 database binding env
})

CDN

//Browser using CDN

const db = await kvstorage.KVStorage({
	runtime:'browser',
	storageName:'storage'
})

Initialization parameters

await init({
	runtime?:string,
	storageName?:string,
	databaseBinding?:any
})

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

Supported runtime :

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

Write key-value pairs

await put(key:string,value:string)

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:string)

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:string)

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

Has key-value pairs

await has(key:string)

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