# Class: LocalCache\<TValue\>

Defined in: [src/abstract/LocalCache.ts:45](https://github.com/clickup/ent-framework/blob/master/src/abstract/LocalCache.ts#L45)

A simple key-value cache stored on the local machine.

- The expectation is that there will be not too many keys stored, since the
  background cleanup process running time to time is O(numKeysStored).
- Guarantees corruption-free writes to the keys from multiple processes
  running concurrently.
- The values which are not requested longer than approximately `expirationMs`
  are auto-removed.
- Each key is stored in an individual file under `dir`. Some temporary files
  may also appear in that directory, but eventually, they will be cleaned up,
  even if they get stuck for some time.
