Simple File Manager on the Web!

---

• Tech Stack will include; redis, mongodb, express, nodejs.
• Making a simple file upload, and download webapp on the web.
• Main goal is to make sure one has a better understanding of caching, queing requests, and many more nodejs functionality.

Synchronous Limits

• All events emitted are usually Asynchronous function, meaning you can either handle them with legacy code callback methods or async await.
• Had a bit of a challenge while checking for the node-redis client connection status, ending up with a simple implementation like this one.

  ...
  
  (async () => {
      // will return false immediately due to the sync nature of the function
      console.log(redisClient.isAlive());   // false
  
      settimeout(() => {
          // allows a time delay, making sure that the connection was made correctly
          console.log(redisClient.isAlive());   // true
      }, 2000);
  
      ...
  })();

• Promisify allows you to turn legacy callback methods into promise objects. -**
