Cache Configurations

Cache configurations are used to define the cache drivers, and the default driver and each driver's options.

Usage

In the src/config directory, make sure to create cache.ts file if not created already.

src/config/cache.ts

import { env } from "@mongez/dotenv";
import { CacheConfigurations, RedisCacheDriver } from "@warlock.js/core";

const cacheConfigurations: CacheConfigurations = {
  drivers: {
    redis: RedisCacheDriver,
  },
  default: env("CACHE_DRIVER", "redis"),
  options: {
    redis: {
      host: env("REDIS_HOST"),
      port: env("REDIS_PORT"),
      password: env("REDIS_PASSWORD"),
    },
  },
};

export default cacheConfigurations;

Configurations

The cache configurations object has the following properties:

• default: This is the default driver that will be used if no driver is specified.
• drivers: This is an object that holds the cache drivers, the key is the driver name, and the value is the driver class.
• options: This is an object that holds the options for each driver, the key is the driver name, and the value is the driver options.

Default Driver

The default property is used to define the default driver that will be called on application boot.

It should be a driver name that is named under the drivers property.

For example, we can set the default cache driver to redis which is declared under the drivers property.

src/config/cache.ts

import { env } from "@mongez/dotenv";
import { CacheConfigurations, RedisCacheDriver } from "@warlock.js/core";

const cacheConfigurations: CacheConfigurations = {
  drivers: {
    redis: RedisCacheDriver,
  },
  default: env("CACHE_DRIVER", "redis"),
  options: {
    redis: {
      host: env("REDIS_HOST"),
      port: env("REDIS_PORT"),
      password: env("REDIS_PASSWORD"),
    },
  },
};

export default cacheConfigurations;

info

If no default driver is defined, then the cache manager will use the NullCacheDriver instead.

Drivers

This is where we define all drivers that might be used in the application, usually, we define only the default driver, but based on the application needs, we might need to define more than one driver.

the driver property is an object that holds the cache drivers, the key is the driver name, and the value is the driver class.

note

Please note we define the driver class, not an instance of the driver as it is lazy instantiated by the cache manager.

info

Please check All Available Drivers to know more about the available drivers.

Options

In the options property, we define the options for each driver, the key is the driver name, and the value is the driver options that will be used when the cache driver is loaded.
