Session Storage Adapter for CloudFlare KV

CloudFlare's KV storage can be used on worker runtimes.
Before using it, you'll need to set up a namespace for your sessions and pass in a KVNamespace object.
You can do that either when creating an instance of KVSessionStorage, or by calling the setNamespace method.

``js
import {shopifyApp} from '@shopify/shopify-app-express';
import {KVSessionStorage} from '@shopify/shopify-app-session-storage-kv';

const shopify = shopifyApp({
sessionStorage: new KVSessionStorage(),
// ...
});

export default {
async fetch(
request: Request,
env: Env,
ctx: ExecutionContext,
): Promise {
shopify.config.sessionStorage.setNamespace(env.MY_KV_NAMESPACE);
// Handle request
},
};

// OR

import {Miniflare} from 'miniflare';
const mf = new Miniflare({
kvNamespaces: ['MY_KV_NAMESPACE'],
});
const shopify = shopifyApp({
sessionStorage: new KVSessionStorage(
await mf.getKVNamespace('MY_KV_NAMESPACE'),
),
// ...
});
`

If you prefer to use your own implementation of a session storage mechanism that uses the SessionStorage` interface, see the implementing session storage guide.
