## Options

| Name | Type | Default | Description |
| :-------------------: | :----------------------------------------------: | :---------------------------------------------: | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **`cacheContext`** | `{String}` | `undefined` | Allows you to override the default cache context in order to generate the cache relatively to a path. By default it will use absolute paths |
| **`cacheKey`** | `{Function(options, request) -> {String}}` | `undefined` | Allows you to override default cache key generator |
| **`cacheDirectory`** | `{String}` | `path.resolve('.cache-loader')` | Provide a cache directory where cache items should be stored (used for default read/write implementation) |
| **`cacheIdentifier`** | `{String}` | `cache-loader:{version} {process.env.NODE_ENV}` | Provide an invalidation identifier which is used to generate the hashes. You can use it for extra dependencies of loaders (used for default read/write implementation) |
| **`write`** | `{Function(cacheKey, data, callback) -> {void}}` | `undefined` | Allows you to override default write cache data to file (e.g. Redis, memcached) |
| **`read`** | `{Function(cacheKey, callback) -> {void}}` | `undefined` | Allows you to override default read cache data from file |
| **`readOnly`** | `{Boolean}` | `false` | Allows you to override default value and make the cache read only (useful for some environments where you don't want the cache to be updated, only read from it) |
