Cache factory

Initial configuration

To begin using the CacheFactory, You will need to register all required adapters during initialization.

import { CacheFactory } from "@daiso-tech/core/cache";
import {
    MemoryCacheAdapter,
    RedisCacheAdapter,
} from "@daiso-tech/core/cache/adapters";
import { Serde } from "@daiso-tech/core/serde";
import type { ISerde } from "@daiso-tech/core/serde/contracts";
import { SuperJsonSerdeAdapter } from "@daiso-tech/core/serde/adapters";
import { Namespace } from "@daiso-tech/core/utilities";
import Redis from "ioredis";

const serde = new Serde(new SuperJsonSerdeAdapter());
const cacheFactory = new CacheFactory({
    // The CacheFactory takes the same settings as Cache class
    namespace: new Namespace("cache"),
    adapters: {
        memory: new MemoryCacheAdapter(),
        redis: new RedisCacheAdapter({
            database: new Redis("YOUR_REDIS_CONNECTION"),
            serde,
        }),
    },
    // You can set an optional default adapter
    defaultAdapter: "memory",
});

Usage examples

1. Using the default adapter

await cacheFactory.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

await cacheFactory.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.

3. Overriding default settings

import { z } from "zod";

await eventBusFactory
    .setNamespace(new Namespace("@my-namespace"))
    // You can overide the cache value type by calling setType or setSchema method again
    .setType<string>()
    .setSchema(z.object({
        name: z.string(),
        age: z.number(),
    }))
    .use("redis")
    .add(["user", "jose@gmail.com"], {
        name: "Jose",
        age: 20,
    });

info

Note that the CacheFactory is immutable, meaning any configuration override returns a new instance rather than modifying the existing one.
