CachierDB

CachierDB

Persistence cache manager that uses an IndexedDB or LevelDB store for partial content and compilation segments. The type of DB used is first determined by the presence of an indexedDB on the global/window reference that contains either an IDBFactory or other supported IndexedDB-like interface (e.g. LevelUP). When an indexedDB reference is not present, an atempt to load a module using the options.dbTypeName as the module name/path that resolves into a function that takes a location path from options.dbLocName as it's first argument.
