Dcache #

Dcache is a simple library to implement application caching in dart inspired by gcache

Feature #

  • Supports expirable Cache, LFU, LRU.
  • Support eviction
  • Automatically load cache if it doesn't exists. (Optional)
  • Async loading of expirate value
  • Callback for evicted items to perform cleanup (Optional)

Example #

Simple use case #

import 'package:dcache/dcache.dart';

void main() {
  Cache c = new SimpleCache(storage: new SimpleStorage(size: 20));

    c.set("key", 42);
    print(c.get("key")); // 42
    print(c.containsKey("unknown_key")); // false
    print(c.get("unknown_key")); // nil
}

Evict items #

import 'package:dcache/dcache.dart';

void main() {
  Cache c = new SimpleCache(storage: new SimpleStorage(size: 20), onEvict: (key, value) {value.dispose();});

    c.set("key", 42);
    print(c.get("key")); // 42
    print(c.containsKey("unknown_key")); // false
    print(c.get("unknown_key")); // nil
}

Loading function #

import 'package:dcache/dcache.dart';

void main() {
  Cache c = new SimpleCache<int, int>(storage: new SimpleStorage(size: 20))
    ..loader = (key, oldValue) => key*10
  ;

    print(c.get(4)); // 40
    print(c.get(5)); // 50
    print(c.containsKey(6)); // false
}
