1. The database schema for the above problem statement is located at models/quizes.js file
2. There are four different REST api's for performing various operations
- localhost:3000/quizes --> for getting list of all quizes, creating a quiz, Removing all quizes
- localhost:3000/quizes/:quizId --> for getting details of a quiz, updating content of a quiz, deleting a quiz
- localhost:3000/quizes/:quizId/questions --> for getting questions of a quiz, adding a question, deleting all questions from quiz
- localhost:3000/quizes/:quizId/questions/:questionId --> getting a question, updating a question, deleting a question
3. The implementation of these end points can be found in routes/quizRouter.js file.
4. All the Post, Put, Delete operations needs to be authorized by providing username and password (username: admin, Password: password). This means only admin can create, update or delete a quiz/question
5. The implementation of authorization step can be found in authenticate.js file in the root folder
6. Cookies are implemented to avoid the need of repeated authorization for admin
7. The user can only see the questions/quizes that are enabled by the admin. This is implemented by filtering the retrieved content from database by respective queries.
- Clone the entire repository to a new folder on desktop
- Open the command prompt from the same folder and type npm install. This will download all the required dependencies which are present in package.json file
- Now open the mongodb terminal and create a new database named quiz. All the quizes and questions will be stored here.
- All the logs will be stored in logs/app.log file
- For doing unit tests type the command npm run test. This will do the unit tests on different end points for sanity checking.
- To start the server enter the command npm start
