project: Memory Game: rebuild using a modern web frontend framework

Take a look at this: PROJECT: Memory game web app

Instructions

Part 1: MVP

Create an MVP memory game using Angular or React. Follow a TDD procedure.

  • The game should draw a grid with 6 columns and 5 rows
  • The cards in the game should be randomized
  • When the game finishes then display a message on the screen that says “Congratulations! You are done!” There should be a button labelled “Play Again” that the player can use to restart the game

Part 2: Count-down

  • Draw a timer widget on the screen. It should start off showing 2 minutes and count down to zero
  • The color of the timer should be green initially
  • the timer should turn orange after one minute has passed
  • the timer should turn red when there are 30 seconds left on the clock
  • when the timer runs out:
    • flip all the cards over to reveal what is underneath
    • display a message saying “Sorry! You lost the game”. There should be a button labelled “Play Again” that the player can use to restart the game

Part 3: Winning stats

When the user wins the game then the congratulations message should include:

  • the number of turns taken (1 turn == 2 clicks)
  • the amount of time taken

Part 4: ExpressJs

  • Serve your game using ExpressJS (as static content)
  • Connect a MongoDB database
  • expose the following json api endpoints:
    • POST update_score: This should accept a json object like this {name:"a string", time: number of seconds, turns: number of turns taken}. This endpoint must update the database
    • GET leaderboard/time: This should return the top 10 fastest people to win the game
    • GET leaderboard/turns: This should return the top 10 people to win the game using the fewest clicks

Part 5: Ajax

  • When the game starts then the user will need to enter their name

  • Whenever a user successfully wins the game then:

    • their score should be stored in MongoDB updated through use of the update_score endpoint
    • the two leaderboards should be fetched and displayed on the page
    • If the current user is on a leaderboard then they should be highlighted

  • Whenever a player loses the game

    • display the two leaderboards
