Package Exports

nx-cache
nx-cache/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (nx-cache) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

nx-cache

Minimal in-memory cache SDK for Node.js.

No setup. No config. Just use it.

Install

npm i nx-cache

Usage

import { createNxCache } from "nx-cache";

const cache = createNxCache();

Write

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

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

Read

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:

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

Search

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

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

Reset

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
