📚 Usage

The package export methods to instantiate and close connection to Redis. By default, all features automatically re-use the current Redis connection.

import assert from "assert";
import {
  initRedis,
  getRedis,
  closeAllRedis
} from "@myunisoft/redis";

const publisher = await initRedis();
const subscriber = await initRedis({}, "subscriber");

assert.strictEqual(publisher, getRedis());
assert.strictEqual(subscriber, getRedis("subscriber"));

await closeAllRedis();

📜 API

export type Instance = "subscriber" | "publisher";

type CustomRedisOptions: Partial & { port?: number; host?: string; };

getRedis(instance: Instance = "publisher"): Redis;

This function return either the publisher instance, either the subscriber instance.

initRedis(redisOptions: CustomRedisOptions = {}, instance: Instance = "publisher", external?: boolean): Promise

This function is used to init redis connections. Passing instance with "subscriber" value, it init the local subscriber Redis instance. Otherwise, it init the local publisher Redis instance.

getConnectionPerf(instance: Instance = "publisher", redisInstance?: Redis): Promise

export interface GetConnectionPerfResponse {
  isAlive: boolean;
  perf?: number;
}

This function is used to check Redis connection state.

const { isAlive } = await getConnectionPerf(); // true

closeRedis(instance: Instance = "publisher", redisInstance?: Redis, forceExit: boolean = false): Promise

This function is used to close a single local instance.

closeAllRedis(redisInstance?: [Redis, Redis], forceExit: boolean = false): Promise

This function is used to close every local instances.

clearAllKeys(instance: Instance = "publisher", redis?: Redis): Promise

This function is used to clear all keys from redis db (it doesn't clean up streams or pubsub !).

await clearAllKeys();

The package also exports many classes listed below.

• KVPeer
• TimedKVPeer
