Cache

Abstract cache interface backed by tapable hooks for reading, writing, idle transitions, and shutdown across webpack cache implementations.

new Cache(): Cache

Initializes the cache lifecycle hooks implemented by cache backends.

cache.beginIdle(): void

Signals that webpack is entering an idle phase and cache backends may flush or compact pending work.

cache.endIdle(callback): void

Signals that webpack is leaving the idle phase and waits for cache backends to finish any asynchronous resume work.

cache.get(identifier, etag, callback): void

Retrieves a cached value and lets registered gotHandlers observe the result before the caller receives it.

cache.shutdown(callback): void

Shuts down every registered cache backend and waits for cleanup to finish.

cache.store(identifier, etag, data, callback): void

Stores a cache entry for the identifier and etag through the registered cache backend hooks.

cache.storeBuildDependencies(dependencies, callback): void

Persists the set of build dependencies required to determine whether the cache can be restored in a future compilation.
