关于您遇到的“npm error lrucache is not a constructor”错误,这通常不是一个直接的npm错误消息,而是可能在运行时从JavaScript代码中抛出的异常。这个问题表明您可能在尝试使用lrucache作为一个构造函数来创建新对象,但实际上它的使用方式可能并非如此。以下是一些解决这个问题的步骤和建议: 1. 理解错误信息 错误信息...

To enable caching, make sure that LRUCache is loaded. It's installed by default for Node, but in the browser you need to load lru-cache.js (perhaps from the Bower-compatible variant). Or you can pass any other cache instance as an option to the constructor, as long as it has get,...
* Note: if `undefined` is specified as a value, this is an alias for * {@link LRUCache#delete} * * Fields on the {@link LRUCache.SetOptions} options param will override * their corresponding values in the constructor options for the scope * of this single `set()` operation. * * ...

LRUCache Utility class for the TilesRenderer to keep track of currently used items so rendered items will not be unloaded. .maxSize maxSize=800:number The maximum cached size in number of items. If that current amount of cached items is equal to this value then no more items can be cache...
The driver passes its parameters through to the lru-cache constructor. maxThe maximum size of the cache. DefaultInfinity, which is kind of pointless. maxAgeMaximum age of an item in ms. Default isnull, meaning to not expire items.
When then current cache fills, it becomes the previous cache and a new, empty current cache is created. Subsequent get calls will promote elements in the previous cache to the current cache. Once the current cache fills, the caches are again turned over and all LRU items still residing in ...
or you can add the entire context as a member of the class if you wish. All you need to do is add the field(s) to the options argument of the constructor and call super passing in options. For example, if you put the logged-in user's ID on context ascontext.currentUserIdand you...
BatchedSQLDataSource has an initialize method that Apollo will call when a new request is routed. If no cache is provided in your Apollo server configuration, SQLDataSource falls back to the same InMemoryLRUCache. Context If you pass a context property into the constuctor's config then it...
