-You can tweak several details of the behavior of this class, check out Props for more information.
By default, no tweaking is required.
-Usage:
const entries: [string, any][] = [];
for (const [k, v] of storage) {
entries.push([k, v]);
}
entries; // equals: [[ 'key1', '1' ], [ 'key2', '2' ], ... ]
iterator over key/value pairs
-calls localStorage.clear() and returns true if it worked – otherwise false.
Deletes key from local storage
Throws an error only if you try to delete the reserved key to record recent entries.
-Delete a value or nested object from within a nested object at the given path. It returns the deleted object.
-Delete all keys with the given prefix
-remove a key from the recently used list
-Each value in localStorage is a string. For specific prefixes, this deserializes the value. As a fallback, it optionally tries to use JSON.parse. If everything fails, the plain string value is returned.
-Get data from a nested object
-the number of recent keys tracked
-Keys of last recently used entries. The most recent one comes first!
-Return all keys in local storage, optionally sorted.
-Returns true, if we can store something in local storage at all.
-avoid trimming more useful entries, we keep an array of recently modified keys
-specific types are serialized with a prefix, while plain strings are stored as they are.
-Wrapper around localStorage, so we can safely touch it without raising an exception if it is banned (like in some browser modes) or doesn't exist.
-Set data in nested objects and merge with existing values
-number of items stored in the local storage – not counting the "recent key" itself
-Trim the local storage in case it is too big. In case there is an error upon storing a value, we assume we hit the quota limit. Try a couple of times to delete some entries and saving the key/value pair.
-Returns true, if we can store something in local storage at all. This is used for testing and during initialization.
