Configure file caches	Caches	Configure file caches.

This is the default configuration:

{{< code-toggle config=caches />}}

Keys

dir

(string) The absolute file system path where the cached files will be stored. You can begin the path with the :cacheDir or :resourceDir token. These tokens will be replaced with the actual configured cache directory and resource directory paths, respectively.

maxAge

(string) The duration a cached entry remains valid before being evicted. A value of 0 disables the cache. A value of -1 means the cache entry never expires (the default).

Tokens

:cacheDir

(string) The designated cache directory. See details.

:project

(string) The base directory name of the current Hugo project. By default, this ensures each project has isolated file caches, so running hugo --gc will only affect the current project's cache and not those of other Hugo projects on the same machine.

:resourceDir

(string) The designated directory for caching output from asset pipelines. See details.
