Welcome to ACM@SJSU Dev Team Node Backend Interview

This technical interview will test your understanding of Node, Express, HTTP, and Typescript.

The goal of this interview is for you to develop functional routes that handle basic HTTP requests.

Project Requirements

You are developing a professor rating backend application for SJSU, similar to Rate My Professor. This application accepts requests from the client to create, get, update, and delete reviews of professors. Your task is to develop API routes for the /reviews endpoint.

Review object:

type Review = {
  id: number;
  professorName: string;
  courseName: string;
  rating: number;
  grade: string;
  tags: string[];
  takeAgain: boolean;
  content: string;
}

You must create the following routes:

• GET /reviews - Return a list of all reviews
  • Response Body: { reviews: Review[] }
  • Response Status: 200
• POST /reviews - Create a review object
  • Request Body: Omit<Review, "id">
  • Response Body: { review: Review }
  • Response Status: 201

  NOTE: You can generate the Review["id"] however you like

• GET /reviews/:id - Return Review with given id
  • Response Body: { review: Review }
  • Response Status: 200
• PUT /reviews/:id - Update Review with given id
  • Request Body: Omit<Review, "id">
  • Response Body: Not Content
  • Response Status: 204
• DELETE /reviews/:id - Delete Review with given id
  • Response Body: Not Content
  • Response Status: 204

We will assume that all the requests have valid request bodies and parameters. To store the Review object we will use an in-memory list of Review, which is already provided.

Testing

We will test using the following commands in sequence:

curl http://localhost:3000/reviews

curl -XPOST -H 'Content-Type: application/json' -d '{"professorName": "David Taylor", "courseName": "DSA", "rating": 3, "tags": ["java"], "takeAgain": true, "grade": "B-", "content": "hard course" }'  http://localhost:3000/reviews

curl http://localhost:3000/reviews/<id>

curl -XPUT -H 'Content-Type: application/json' -d '{"professorName": "David Taylor", "courseName": "DSA", "rating": 3, "tags": ["java"], "takeAgain": true, "grade": "A-", "content": "easy course" }'  http://localhost:3000/reviews/<id>

curl http://localhost:3000/reviews/<id>

curl -XDELETE http://localhost:3000/reviews/<id>

curl http://localhost:3000/reviews
