ts-cache-decorators

Install

npm i @t.voslar/ts-cache-decorator

Configuration

Choose one of the supported storages (MemcacheElastiCache or RedisStorage) or create your new storage which implements IStorage.

const cacheStorage = new MemcachedElastiCacheStorage('localhost:11211', {})
useStorage(cacheStorage)

Now you can use @Cache decorator

@Cache({ type: 'normal', cacheKey: 'getUser', ttl: 3 })
async getUser (userId: string): Promise<User> {

Above caching will take cacheKey + parameters (which is just userId in this case) and will create cache key, which will expire after 3 seconds.

If you need to filter some parameters you can use filterParams param.

@Cache({ type: 'normal', cacheKey: 'getUser', ttl: 3, filterParams: ['otherParam'] })
async getUser (userId: string, otherParam: boolean): Promise<User> {
