new CatboxRedis.Engine(options)

The connection can be specified with one (and only one) of:

• client - a custom Redis client instance where client must:

  • be manually started and stopped,
  • be compatible with the ioredis module API, and
  • expose the status property that must be set to 'ready' when connected.

• url - a Redis server URL.

• socket - a unix socket string.

• cluster - an array of { host, port } pairs.

Or:

• host - a Redis server hostname. Defaults to '127.0.0.1' if no other connection method specified from the above.
• port - a Redis server port or unix domain socket path. Defaults to 6379 if no other connection method specified from the above.

catbox options:

• partition - a string used to prefix all item keys with. Defaults to ''.

Other supported Redis options:

• password - the Redis authentication password when required.
• db - a Redis database name or number.
• sentinels - an array of { host, port } sentinel address pairs.
• sentinelName - the name of the sentinel master (when sentinels is specified).
• tls - an object representing TLS config options for ioredis.

The plugin also accepts other redis options not mentioned above.

Usage

Sample catbox cache initialization:

const Catbox = require('@hapi/catbox');
const { Engine: CatboxRedis } = require('@hapi/catbox-redis');


const cache = new Catbox.Client(CatboxRedis, {
    partition : 'my_cached_data',
    host: 'redis-cluster.domain.com',
    port: 6379,
    db: 0,
    tls: {},
});

When used in a hapi server (hapi version 18 or newer):

const Hapi = require('hapi')
const { Engine: CatboxRedis } = require('@hapi/catbox-redis');

const server = new Hapi.Server({
    cache : [
        {
            name: 'my_cache',
            provider: {
                constructor: CatboxRedis,
                options: {
                    partition : 'my_cached_data',
                    host: 'redis-cluster.domain.com',
                    port: 6379,
                    db: 0,
                    tls: {},
                }
            }
        }
    ]
});

Tests

The test suite expects:

• a redis server to be running on port 6379
• a redis server listenning to port 6378 and requiring a password: 'secret'
• a redis cluster contains nodes running on ports 7000 to 7005
