## README

# nx-cache

Minimal in-memory cache SDK for Node.js.

No setup. No config. Just use it.

---

## Install

```bash
npm i nx-cache
```

---

## Usage

```ts
import { createNxCache } from "nx-cache";

const cache = createNxCache();
```

---

## Write

```ts
cache.write(
  "policy",
  { allow: true },
  {
    scope: { orgId: "acme", env: "prod" },
    metadata: { source: "api" },
  }
);
```

* Same key + different scope = different entry
* Scope can be `null`

---

## Read

```ts
const res = cache.read("policy", { orgId: "acme", env: "prod" });

if (res.found) {
  console.log(res.value);
  console.log(res.metadata);
  console.log(res.meta.savedAt);
}
```

Without scope:

```ts
cache.read("policy"); // equivalent to scope = null
```

---

## Search

```ts
const results = cache.search("policy", { orgId: "acme", env: "prod" });

for (const r of results) {
  console.log(r.value, r.metadata);
}
```

---

## Reset

```ts
cache.resetKey("policy", { orgId: "acme", env: "prod" });
cache.resetAll();
```

---

## Behavior summary

* Default TTL: **1 year**
* Expired entries are treated as not found
* Metadata is user-defined and returned on read/search
* Cache is per-process (memory only)

---

## Future extensions (not in v1)

* Redis backend
* Disk persistence
* Stale reads
* Namespaced caches
