Battle-tested, strongly typed caching with metrics and tracing out of the box.

Features

- Tiered caching
- Memory Cache
- Cloudflare Cache
- Cloudflare KV (todo)
- Cloudflare R2 (todo)
- Emit metrics

Quickstart

``bash
npm install @unkey/cache
`

`ts
import {
createCache, DefaultStatefulContext } from "@unkey/cache";
import { MemoryStore, CloudflareStore } from "@unkey/cache/stores";


// Only required in stateful environments.
// Cloudflare workers or Vercel provide an executionContext for you.
const ctx = new DefaultStatefulContext();

type User = {
id: string;
email: string;
};

type Post = {
slug: string;
title: string;
content: string;
publishedAt: Date;
};

const fresh = 60_000;
const stale = 900_000;

const ctx = new DefaultStatefulContext();

const memory = new MemoryStore({
persistentMap: new Map(),
});

const cloudflare = new CloudflareStore({
cloudflareApiKey: "CLOUDFLARE_API_KEY",
zoneId: "CLOUDFLARE_ZONE_ID",
domain: "my-domain-on-cloudflare",
});
const cache = createCache({
account: new Namespace(ctx, {
stores: [memory],
fresh,
stale,
}),
user: new Namespace(ctx, {
stores: [memory, cloudflare],
fresh,
stale,
}),
});

await cache.user.set("chronark", { id: "chronark", email: "iykyk" });

// This is fully typesafe and will check the stores in the above defined order.
const user = await cache.user.get("chronark");
`

Add your database query and the cache will return the stale data while revalidating the data in the background.

`ts
const user = await cache.user.swr("chronark", async (id) => {
return await db.query.users.findFirst({
where: (table, { eq }) => eq(table.id, id),
});
});
``
