RedisClient library used for RedisStore

[Anup Francis]

I am trying to use the RedisStore for sessionId storage and I am not seeing any entry in RedisDB for this. So, I want to know which RedisClient is being used to insert key in RedisDB.
I use "ioredis": "^5.2.5" in my nodejs application. The admin UI is working correctly. I was expecting an entry in Redis but not seeing one. So, I want to understand this a little better.

Hi! We use redis@3:

socket.io-admin-ui/package.json

Line 52 in fcf32cc

 "redis": "^3.0.2", 

Not sure the ioredis package supports the syntax here:

socket.io-admin-ui/lib/stores.ts

Lines 31 to 72 in fcf32cc

 export class RedisStore extends Store { 
   private options: RedisStoreOptions; 
  
   constructor(readonly redisClient: any, options?: Partial<RedisStoreOptions>) { 
     super(); 
     this.options = Object.assign( 
       { 
         prefix: "socket.io-admin", 
         sessionDuration: 86400, 
       }, 
       options 
     ); 
   } 
  
   private computeKey(sessionId: string) { 
     return `${this.options.prefix}#${sessionId}`; 
   } 
  
   doesSessionExist(sessionId: string): Promise<boolean> { 
     return new Promise((resolve, reject) => { 
       this.redisClient.exists( 
         this.computeKey(sessionId), 
         (err: Error | null, result: any) => { 
           if (err) { 
             reject(err); 
           } else { 
             resolve(result === 1); 
           } 
         } 
       ); 
     }); 
   } 
  
   saveSession(sessionId: string) { 
     const key = this.computeKey(sessionId); 
     this.redisClient 
       .multi() 
       .set(key, true) 
       .expire(key, this.options.sessionDuration) 
       .exec(); 
   } 
 } 

But you should be able to write your own store by extending the Store class.
