Documentation

The CacheXS package comes with a comprehensive set of features designed to make cache in your application straightforward and efficient. This section provides an overview of its capabilities and guides on how to use them effectively.

• Features Overview

  • Simple Cache Management: Easily cache the data in Redis with simple functions.

• Usage & Configuration

  • Installation

    Refer to the Installation section for instructions on how to install CacheXS using various package managers.

  • Initializing the Library:

    You can create a new instance of CacheXS and pass the configuration for it directly like this example below:

    const cacheXS = new CacheXS({
    	redisConnection: ioredis,
    	namespace: 'myCache',
    	enableDebug: true,
    })

    Alternatively, you can split the creation of the new instance and the configuration, useful when split up into different modules for bootstrapping.

    const cacheXS = new CacheXS()
    
    cacheXS.configure({
    	redisConnection: ioredis,
    	namespace: 'myCache',
    	enableDebug: true,
    })

• Methods/Properties

  • get Retrieves the value associated with the specified key from the cache.

    const stringValue = await cacheXS.get<string>('myKey') // -> myValue
    const stringValue = await cacheXS.get<number>('myKey') // -> 123
    const objectValue = await cacheXS.get<MyObject>('myKey') // -> { name: 'John', age: 30 }

  • set: Sets a value in the cache.

    await cacheXS.set('myKey', 'myValue')
    await cacheXS.set('myKey', 123)
    await cacheXS.set('myKey', { name: 'John', age: 30 }, { expiresIn: 360 })

  • setForever Sets a value in the cache forever

    await cacheXS.setForever('user', { name: 'John Doe', age: 30 })

  • getOrSet Retrieves the value associated with the specified key from the cache. If the value does not exist, it sets the value to the provided fallback value and returns it.

    const username = await cacheXS.getOrSet('myKey', 'myValue')

  • getOrSetForever Retrieves the value associated with the specified key from the cache. If the value does not exist, it sets the specified fallback value in the cache and returns it.

    value = await cacheXS.getOrSetForever('myKey', 'defaultValue')

  • delete Deletes a cache entry by its key.

    await cacheXS.delete('myKey')

  • deleteMany Deletes multiple cache entries specified by the given keys.

    await cacheXS.deleteMany(['myKey', 'myKey2', 'myKey3'])

  • clear Clears all cache entries in the CacheXS instance.

    await cacheXS.clear()

  • has Checks if a key exists in the cache.

    await cacheXS.has('myKey') // -> True || False

  • missing Checks if a key is missing in the cache.

    await cacheXS.missing('myKey') // -> True || False

  • concatenateKey Concatenates the given key with the namespace and returns the resulting string.

    await cacheXS.concatenateKey('myKey') // -> 'CacheXS:myKey'

  • redisConnection Gets the Redis connection.

    cacheXS.redisConnection // -> ioredis instance

  • redisUrl Gets the Redis URL.

    cacheXS.redisUrl // -> 'redis://user:pass@localhost:6379'

  • redisConfig Gets the Redis configuration.

    cacheXS.redisConfig // -> { host: 'localhost', port: 6379, password: '' }

  • expiresIn Gets the expiration time in seconds.

    cacheXS.expiresIn // -> 60

  • namespace Gets the namespace of the cache.

    cacheXS.namespace // -> 'CacheXS

  • isDebugEnabled Gets a value indicating whether debug mode is enabled.

    cacheXS.isDebugEnabled // -> True || False
