Football Jerseys Awesomeness









About the Project

Many sports fans are collectors of game-related items, such as remodels of trophies, team hats, or souvenirs from specific matches, and the jersey is one of the hot items that every football fan would want to own a piece. Imagine I have an enterprise that sells football-related merchandise, especially jersey collections, Firebase Realtime Database technology can be an essential part of my company’s tech stack.

Why Firebase?

I can use Firebase Realtime Database as a normal database to store my jersey collection information. Under every specific sports team, all the jerseys ever worn by their players, dating back to decades of years, would be available for the customers. For my side, a powerful database would make all the work easier. Above is the description of using Firebase Realtime Database as a normal database, but it is so much more than that. The most outstanding features of Firebase Realtime Database is in its name, the “Realtime”. It means once the data in the backend is changed, all the display of the data in the frontend would change in a synchronized way. This feature can be powerful for my company when it comes to checking item availability and stock amount.

How to Use Firebase

  • STEP1: Go to Firebase and create a new project
  • STEP2: Click on "Authentication" and set an email address and password in connexion mode
  • STEP3: Create database. Clicking on the "+" button, and enter key name and values
  • STEP4: Use npm packager manager to install Node.js firebase-tools,
  • STEP5: Follow command line prompt to complete firebase initialization
  • STEP6: Start debugging on local environment
  • STEP7: On the front-end assume we are using HTML, import related firebase libraries
  • STEP8: initialize firebase with config,put your own config info in config variable, then start querying data. You can also use .on() function to get realtime data update.
  • STEP9: Finally, you can get your database!

    • Real life Situation

    Imagine FC Barcelona just won The UEFA European Football Championship. We do not know for certain that this will happen so we did not prepare enough stock, and FC Barcelona’s jersey will be very hot in a short amount of time which will cause massive network requests arriving at the server in a short time period. It is for certain that there will be a similar Black Friday phenomenon going on when all the FC fans are eyeing on the inevitable short stock. We assume we use locks on backend so the data can only be modified by one entity at each time, this ensures data consistency; The “Realtime” feature can help FC Barcelona fans check the availability of this jersey easier, so they do not have to reload the page every time they try to see if the jersey is still available. “Realtime” makes Firebase Realtime Database stand out.

    As a result, this document would explain on a general scale, how to use the database to facilitate the marketing and sales of a business-to-customer enterprise. With Firebase Realtime Database, not only data management would be easy but it also solves the data inconsistency problem between backend and frontend.
