Angular CLI - ng cache Command

The ng cache command manages the persistent disk cache, which stores cachable operations like build and test data to speed up processes.

Cache in Angular CLI

The cache is a storage space in Angular CLI where the state and data of cachable operations are stored. These operations include build, test, serve and more. It speeds up the processes because when you re-run the same build, it restores the previous build state and re-uses previously performed operations. As a result, a lot of time is saved while building and testing your applications. By default, the cache results are stored in .angular/cache directory.

Syntax

Following is the syntax of ng cache command −

ng cache [options]

Options

Options are optional parameters of ng cache command.

Sub-Commands of ng cache Command
