Countdown Timer

A shared countdown timer that can be simultaneously experienced by multiple users.

Features

• Clicking the Reset button resets the timer to 3:00 minutes
• Clicking the Start/Stop button unpause and pause the timer respectively
• The timer counts downward, updating every second until it reaches 0:00
• Multiple users can be able to visit the site and all simultaneously see the same value
• Closing or reloading the browser does not impact the timer's behavior. On reload, the site displays the same content as if the page was never closed.
• Implementation of this app avoids excessive writes to persistent storage. This means that the app does not update the database every second with the current time.

Config

Important: You will need to setup a new account project on firebase and create a firestore database to proceed.
Then you will create a config.json file and save it on src/config.json.
