Cache is an essential function of every system. We can use Yao's own cache function to store some temporary data.

Store uses cache, add file stores/cache.lru.json:

Application directory structure:

├── apis # Used to store interface description files
│
├── models # Used to store data model description files
│
├── db
└── stores # is used to store the cache directory
|
└── app.json

Write the code cache.lru.json:

{
  "name": "LRU Cache",
  "description": "LRU cache",
  "type": "lru",
  "option": { "size": 102400 }
}

Use cache in any JS file, Set to set cache, Get to get cached data, create scripts/test.js

function cacheOperation() {
  var cache = new Store("cache");

  cache.Set("key", "for bar .....");

  var cache_info = cache.Get("key");
  return cache_info;
}

run yao run scripts.test.cacheOperation
