Cache management


Function overview

With the ZIM SDK, you can query the local cache file size of the currently logged-in user and clear the local cache.

Query cache

After creating a ZIM object and logging in, you can invoke the queryLocalFileCache interface and pass ZIMFileCacheQueryConfig to query the size of the cache for the current user locally.

The query result will be returned through the callback interface ZIMFileCacheQueriedResult.

Untitled
var config = {
    endTime: 0 // Query the cache size for the current user before this timestamp (UNIX). Fill in 0 or a value later than the current time to get the complete cache size for the current user.
};

zim.queryLocalFileCache(config)
    .then(function ({ totalFileSize }) {
        // Operation succeeded
    })
    .catch(function (err) {
        // Operation failed
    });
