Why?

flat-cache is amazing and I wanted to extend it to add a TLL (key expiry) feature.

Using

1
2    //Some cache options
3    const cacheOpts = {
4      // namespace to use
5      ns: "shorticle-cache",
6      // time to live
7      ttl: 3600 * 24,
8      //dir: '/Directory-To-Save-Data'
9    };
10    
11    const cache = require(".")(cacheOpts);
12    
13    let key = "test-key",
14      value = {tyope:"Object", name:"Some Fancy Object to cache"};
15    
16    cache.set(key, value, 30);
17    
18    console.log(cache.ttl(key));
19    console.log(cache.get(key));
20

This will print:

1
2    { key: 'test-key', expires: 'in a few seconds' }
3    { tyope: 'Object', name: 'Some Fancy Object to cache' }

NOTE:

• ttl defaults to null, meaning no expiry.
• you can use .get(), .set() and .del() methods which map to flat-caches .getKey(), .setKey() and .removeKey() respectively.
• all option values are optional
