Provide a dart cache library usable on web, flutter and server side
Ecache #
Ecache is a simple library to implement application caching in dart
inspired by gcache
Ecache is a fork of dcache with a few contract-breaking changes.
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:ecache/ecache.dart';
void main() {
Cache c = new SimpleCache(storage: SimpleStorage(), capacity: 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:ecache/ecache.dart';
void main() {
Cache c = new SimpleCache(storage: new SimpleStorage(), capacity: 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:ecache/ecache.dart';
void main() {
Cache c = new SimpleCache<int, int>(storage: new SimpleStorage(), capacity: 20)
..loader = (key, oldValue) => key*10
;
print(c.get(4)); // 40
print(c.get(5)); // 50
print(c.containsKey(6)); // false
}
