缓存

缓存是一个模块,用于在简单的界面下封装一般缓存功能

它提供了两个接口 基础缓存 财务报告和审定财务报表 简单缓存

两者的设计都用于缓存含有 id:number 用于识别的字段

基础缓存 是一个对过程有更大控制权的低层.

简单缓存 如果您想要为不同类型对象另设缓存持有人, 则更为合适

使用量

BaseCache

import { BaseCache, MemoryStore } from '@bondsports/cache';

const cache = new BaseCache(new MemoryStore(), console.log, true);

const program = cache.getOrFetchOne('programs', 12, async missingId => ({ id: 12, name: 'program 12' }));

const programs = cache.getOrFetch('programs', [12, 13], async missingIds => [
    { id: 12, name: 'program 12' },
    { id: 13, name: 'program 13' },
]);

cache.invalidateOne('programs', 12);
cache.invalidate('programs', [13]);

SimpleCache

import { BaseCache, MemoryStore } from '@bondsports/cache';

const cache = new SimpleCache(new MemoryStore(), 'programs', async missingIds => [
    { id: 12, name: 'program 12' },
    { id: 13, name: 'program 13' },
]);

const program = cache.getOrFetchOne(12);

const programs = cache.getOrFetch([12, 13]);

cache.invalidateOne(12);
cache.invalidateAll();

SimpleCache with Redis as a store

import { RedisClientType, createClient } from '@redis/client';
import { RedisStore } from '@bondsports/cache';

const client = createClient({ url: 'redis://localhost:6379' });
const store = new RedisStore(client, 1000);
const cache = new SimpleCache(store, 'programs', async missingIds => [
    { id: 12, name: 'program 12' },
    { id: 13, name: 'program 13' },
]);

const program = cache.getOrFetchOne(12);

const programs = cache.getOrFetch([12, 13]);

cache.invalidateAll();

const program = cache.getOrFetchOne(12);

const programs = cache.getOrFetch([12, 13]);
