Back End Assignment - REUNION

Problem Statement

• Build APIs for a social media platform in either NodeJS or Python
• The API should support features like getting a user profile, follow a user, upload a post, delete a post, like a post, unlike a liked post, and comment on a post
• Design the database schema and implement in PostgreSQL or MongoDB

API Endpoints

• GET: /api/user should authenticate the request and return the respective user profile.
  RETURN: User Name, number of followers & followings.
• GET: api/posts/{id} would return a single post with {id} populated with its number of likes and comments
• GET: /api/all_posts would return all posts created by authenticated user sorted by post time.
  RETURN: For each post return the following values
  1. id: ID of the post
  2. title: Title of the post
  3. desc: Description of the post
  4. created_at: Date and time when the post was created
  5. comments: Array of comments, for the particular post
  6. likes: Number of likes for the particular post
• POST: /api/follow/{id} authenticated user would follow user with {id}
• POST: /api/unfollow/{id} authenticated user would unfollow a user with {id}
• POST: api/posts/ would add a new post created by the authenticated user.
  RETURN: Post-ID, Title, Description, Created Time(UTC).
  • Input: Title, Description
• POST: /api/like/{id} would like the post with {id} by the authenticated user.
• POST: /api/unlike/{id} would unlike the post with {id} by the authenticated user.
• POST: /api/comment/{id} add comment for post with {id} by the authenticated user.
• POST: /api/authenticate should perform user authentication and return a JWT token.
  RETURN: JWT token
  • INPUT: Email, Password

  NOTE: Use dummy email & password for authentication. No need to create endpoint for registering new user.`

• DELETE: api/posts/{id} would delete post with {id} created by the authenticated user.
  Return: Comment-ID Input: Comment

Stacks

• Backend: NodeJS (using ExpressJS or Koa) or Python (using Django). Use other helping libraries.
• Database: PostgreSQL or MongoDB

Instructions

• Implement the mentioned functionalities by writing your code & hosting it on Render.

• Submit the Render hosted link for the deployed APIs and Github or Gitlab public repository link for the deployed code in the form below.

• Provide the list of the functional testcases specific to each API endpoint with description in an Excel sheet (sample sheet) & submit it via the form below.
  

  💬 Sample excel file for tests Sample Test Case

  • Don’t write all the testcase but try to focus on the important testcases according to your understanding.

• Implement the testcases using the language specific framework or library like Mocha or Chai.js for Node.

  • Commit the testcase code in the git repo & provide the commands to run the testcases.

• Create a single docker file for running the full web app under a single docker image. Commit the docker file under the same repo & provide the link.

  • Please note docker file should take care of the database, running testcases & other dependencies installation.
