@cache-utils/decorators

@Cacheable / @CacheEvict method decorators for @cache-utils/core, usable with any DI framework or none.

Install

npm install @cache-utils/decorators @cache-utils/core

Usage

Configure a CacheManager once at startup, then decorate methods:

import { CacheManager } from "@cache-utils/core";
import { configureCacheManager, Cacheable, CacheEvict } from "@cache-utils/decorators";

configureCacheManager(new CacheManager());

class ProductService {
  @Cacheable({ keyFrom: (id: string) => `product:${id}`, ttlSeconds: 300 })
  async getProduct(id: string) {
    return db.products.findOne(id);
  }

  @CacheEvict({ keyFrom: (id: string) => `product:${id}` })
  async updateProduct(id: string, data: Partial<Product>) {
    return db.products.update(id, data);
  }
}

• key / keyFrom(...args) — static or per-call cache key. Falls back to the method name if neither is given.
• ttlSeconds / ttlSecondsFrom(...args) (@Cacheable only) — static or per-call TTL.

Using NestJS? @cache-utils/nestjs wires configureCacheManager into a forRoot() module for you.
