Importing RedisModule from the library

This module provide an Hapiness extension for Redis. To use it, simply register it during the bootstrap step of your project and provide the RedisExt with its config


@HapinessModule({
    version: '1.0.0',
    providers: [],
    declarations: [],
    imports: [RedisModule]
})
class MyApp implements OnStart {
    constructor() {}
    onStart() {}
}

Hapiness
    .bootstrap(
        MyApp,
        [
            /* ... */
            RedisExt.setConfig(
                {
                    url: '//redis_url:6379',
                    password: 'password',
                    db: '1'
                    /* ... Other options ... */
                }
            )
        ]
    )
    .catch(err => {
        /* ... */
    });

RedisExt needs a ClientOpts object so you can provide all the properties defined in the interface (see below)

export interface ClientOpts {

    host?: string;
    port?: number;
    path?: string;
    url?: string;
    parser?: string;
    string_numbers?: boolean;
    return_buffers?: boolean;
    detect_buffers?: boolean;
    socket_keepalive?: boolean;
    no_ready_check?: boolean;
    enable_offline_queue?: boolean;
    retry_max_delay?: number;
    connect_timeout?: number;
    max_attempts?: number;
    retry_unfulfilled_commands?: boolean;
    auth_pass?: string;
    password?: string;
    db?: string;
    family?: string;
    rename_commands?: { [command: string]: string };
    tls?: any;
    prefix?: string;
    retry_strategy?: RetryStrategy;
    ping_keepalive_interval?: number: // In seconds
}

Using Redis inside your application

To use redis, you need to inject inside your providers the RedisClientService.


class FooProvider {

    constructor(private _redis: RedisClientService) {}

    bar(): Observable<string> {
        return this._redis.connection.get('my_key');
    }

}

RedisClientService functions

RedisClientService.connection this will return you the redis client and you will be able to call on it every redis command (see the list of commands here)

INFO All function returns RxJS Observable
