providers: [ CacheService ]
})
export class ExampleComponent {
constructor(private _cacheService: CacheService) {}
public func() {
//set global prefix as build version
this._cacheService.setGlobalPrefix(BUILD_VERSION);
//put some data to cache "forever"
//returns true is data was cached successfully, otherwise - false
let result: boolean = this._cacheService.set('key', ['some data']);
//put some data to cache for 5 minutes (maxAge - in seconds)
this._cacheService.set('key', ['some data'], {maxAge: 5 * 60});
//put some data to cache for 1 hour (expires - timestamp with milliseconds)
this._cacheService.set('key', {'some': 'data'}, {expires: Date.now() + 1000 * 60 * 60});
//put some data to cache with tag "tag"
this._cacheService.set('key', 'some data', {tag: 'tag'});
//get some data by key, null - if there is no data or data has expired
let data: any|null = this._cacheService.get('key');
//check if data exists in cache
let exists: boolean = this._cacheService.exists('key');
//remove all data from cache with tag "tag"
this._cacheService.removeTag('tag');
//remove all from cache
