Climate game - Final project at Technigo Bootcamp

A game built in React aimed towards children to create awarness of and interest in the climate change.

  1. Create an account/login or choose to play as guest.
  2. Choose one of three games to play.
  3. The games are either to answer a question or to drag and drop objects.
  4. Choose to finish the game or continue by playing one of the other games.
  5. When statified choose to end the game and send your result to the highscore list.


We set the basic structure and sketch of MVP in Figma before starting to code. This helped us to know where to start and made it easier to divide the tasks. We worked in branches and merged when needed without any major issues. This also helped in making the process smooth and made it possible to work on different tasks at the same time. We used React and Redux as a base for the frontend and Node.js and express for the backend.


Our MVP was to have three questions a user could play and then send their score to the highscore, without Login. We fetched the questions from our backend and used useState and conditional rendering to handle the response to show different pages depending on the answer. We use dispatch to update the score in redux if the answer was correct. After testing in CodePen we used two different libraries for the drag and drop functions. One library is called React-sortable-hoc and gives the user the possibility to sort items in different orders. It's found in task 3 where the user can sort vehicles in the order the user sees fit. The other libraries is called React-Dnd-html5-backend and React-dnd-touch-backend and makes it possible for the user to drag an item and drop it into a box or a container. In our application we've used it in task 2 where the user can recycle different items into specific trash bins. If the user places all items correctly he or she will recieve one point. The same goes for task 3 where the user gets a point when sorting the vehicles in the correct order. In task 2 we are aware that the drag n drop does not work as we would like to in mobile view. The user can choose to end the game and then will be shown a oppurtunity to send their score to the highscore list together with a chosen user name.

When this was in place we made a more final design of the UI in Figma and styled accordingly with styled components and imported cutom made illustrations.

We then proceeded to our strech goal of having a user signup and login. Using an Accesstoken from the backend to see if the user is logged in or not, we use conditional rendering to adjust the UI if the user is logged in or not. For example to show a logout button, hide the input of user name when sending score to highscore (and instead sending the user's name from taken from the database). When logged in the score is stored and updated directly in the user database using POST and then sent to Redux using dispatch.


We have three different collections made with MongoDB and mongoose: the questions, highscore and user information. We have both GET and POST endpoints for highscore, and use filter to only send the top 10 in the response. We have a GET endpoit for the questions that lists all of them together with the answers and description. We have POST endpoints for login, signup and logout. Signup (/users) creates a user using the User model created with mongoose and encrypts the password using bcrypt and pre schema. The Login (/sessions) verifies username and password sent from frontend and generates a new accesstoken. Logout finds the user by ID and resets the accesstoken to null. The last endpoint is a POST for user score that finds the user by ID and updated it's score and send the updated value in the reponse.

We have worked with our application in a way to secure it will be accessible for all people.

We have tested our application in both Lighthouse and Wave to check the accessibility. The application scores as following on Lighthouse:

  • Accessibility: 90
  • Best practices: 100
  • SEO: 92

In Wave our application passes the test with no errors or contrast errors.
