CacheResolver

The CacheResolver class provides a flexible way to configure and switch between different cache adapters at runtime.

Initial configuration

To begin using the CacheResolver, you will need to register all required adapters during initialization.

./samples/cache-resolver-initial-config.ts

import { CacheResolver } from "eridu-tech/cache";
import { MemoryCacheAdapter } from "eridu-tech/cache/memory-cache-adapter";
import { RedisCacheAdapter } from "eridu-tech/cache/redis-cache-adapter";
import { SuperJsonSerde } from "eridu-tech/serde/super-json-serde";
import { Redis } from "ioredis";

type User = {
    name: string;
    age: number;
};

const serde = new SuperJsonSerde();
export const cacheResolver = new CacheResolver<"memory" | "redis", User>({
    adapters: {
        memory: new MemoryCacheAdapter(),
        redis: new RedisCacheAdapter({
            database: new Redis("YOUR_REDIS_CONNECTION"),
            serde,
        }),
    },
    // You can set an optional default adapter
    defaultAdapter: "memory",
});

await cacheResolver.init();

Usage

1. Using the default adapter

./samples/cache-resolver-default-adapter.ts

import { cacheResolver } from "./cache-resolver-initial-config.js";

await cacheResolver.use().add("user/jose@gmail.com", {
    name: "Jose",
    age: 20,
});

danger

Note that if you dont set a default adapter, an error will be thrown.

2. Specifying an adapter explicitly

./samples/cache-resolver-specific-adapter.ts

import { cacheResolver } from "./cache-resolver-initial-config.js";

await cacheResolver.use("redis").add("user/jose@gmail.com", {
    name: "Jose",
    age: 20,
});

danger

Note that if you specify a non-existent adapter, an error will be thrown.
