You are to write a new API that will allow users to share feedback on their grocery orders and allow visibility to a live operations team.
Users can rate their orders from 1 to 5 and leave a comment. Order ID is provided in the url path and the User ID is in the header named UserId.
User can only leave one feedback per order.
1 - Write an HTTP endpoint for users to be able to create/read/edit/delete a feedback for an order.
2 - Write an HTTP endpoint to get the last 20 feedbacks left by users and allow filtering by rating.
- The API should follow typical RESTful API design pattern.
- The data should be saved in the DB.
- Provide proper API documentation.
- Proper error handling should be used.
Use any libraries that you would normally use if this were a real production App. Please note: we're interested in your code & the way you solve the problem, not how well you can use a particular library or feature.
We're interested in your method and how you approach the problem just as much as we're interested in the end result.
Here's what you should strive for:
- Good use of the backend stack selected
- API design best practices.
- Solid testing approach.
- Extensible code.
- Use Springboot (Java or Kotlin), NodeJs (Express, Loopback or Hapi framework) or DotNetCore Framework (C#).
- Use any persistence store, explain your selection.
- Write concise and clear commit messages.
- Write clear documentation on how it has been designed and how to run the code.
- Provide proper unit tests.
- Add an endpoint to allow users share feedback about the items contained in its orders
- Providing an online demo is welcomed, but not required.
We look forward to seeing what you can do. Remember, although it is a test, there are no specific right or wrong answers that we are looking for - just do the job as best you can.
