Environment Variables

The following environment variables need to be set to work with this package:

##### Redis Config
export REDIS_ENABLED=false
export REDIS_AUTH_ENABLED=false
export REDIS_HOST=
export REDIS_PORT=
export REDIS_AUTH=
export REDIS_KEY_PREFIX=
export REDIS_PING_INTERVAL=

| Variable Name | Required | Default | Description | | --------------------- | -------- | ------------------------ | ------------------------------------- | | REDIS_ENABLED | No | false | Enables/Disables Redis functionality | | REDIS_AUTH_ENABLED | No | false | Enables/Disables Redis authentication | | REDIS_HOST | No* | - | Redis server host address | | REDIS_PORT | No* | - | Redis server port number | | REDIS_AUTH | No** | - | Redis authentication password | | REDIS_KEY_PREFIX | No | - | Prefix to be added to all Redis keys | | REDIS_PING_INTERVAL | No | 1800000 (30 minutes) | Ping interval in milliseconds |

Note:

• * - Required fields if REDIS_ENABLED is set to true.
• ** - Required fields if REDIS_AUTH_ENABLED is set to true.

Creating an Instance

import { RedisSdk } from '@am92/redis'

const redisSdk = new RedisSdk()

export default redisSdk

Note: You do not need to set any environment variables if you wish to pass your own config.

Self-managed Config

If you wish to pass your custom 'config' for the RedisSdk, then you can avoid setting any environment variables defined above and pass your own redis config as follows:

import { RedisSdk } from '@am92/redis'

const config = {
  CONNECTION_CONFIG: {
    socket: {
      host: '',
      port: 6379,
      tls: true
    },
    password: '',
    pingInterval: 0
  },
  KEY_PREFIX: ''
}

const redisSdk = new RedisSdk(config)

export default redisSdk

Connection Management

To manage redis connections for RedisSdk Instances, connect and disconnect methods are provided and they can be called as shown below. The connect method must be called before before using the RedisSdk Methods.

// To establish a connection
await redisSdk.connect()

// To release the connection
await redisSdk.disconnect()

// To force release the connection
await redisSdk.disconnect(true)
