Introduction

You were hired as a consultant for BestBlogs^TM company. The company needs your help with finishing the implementation of a REST api for its newest blog product. Your client has already written some tests and implemented some parts of the .NET service. You were tasked to finish the implementation and make all tests pass. Follow this README to complete the code in a correct order. Good luck!

Persistence layer

Implement the empty methods in src/Repository/CommentRepository.cs and src/Repository/PostRepository.cs. You should use the in memory database, in src/Repository/BlogContext.cs, to persist the data.

• CommentRepository.GetAll - finds all existing comments

• CommentRepository.Get - find the comment by id

• CommentRepository.Create - inserts a given comment

• CommentRepository.Update - updates a given comment

• CommentRepository.Delete - deletes a given comment

• CommentRepository.GetByPostId - finds all comments by post id

• PostRepository.GetAll - finds all existing posts

• PostRepository.Get - finds the post by id

• PostRepository.Create - inserts a given post

• PostRepository.Update - updates a given comment

• PostRepository.Delete - deletes a given comment

Web layer

Implement a web layer for the blog API. This step involves implementing REST API controllers in src/Api/Controllers folder.

Comment endpoints

• GET /comments - returns all comments
• GET /comments/{id} - returns comment by id
• POST /comments - creates a new comment
• PUT /comments - updates a comment
• DELETE /comments/{id} - deletes a comment by id

Post endpoints

• GET /posts - returns all posts
• GET /posts/{id} - returns post by id
• POST /posts - creates a new post
• PUT /posts - updates a post
• DELETE /posts/{id} - deletes a post by id
• GET /posts/{id}/comments - returns all comments for a given post id

Request Validations

Implement the following request validations:

Comment

• PostId must be an existing post id
• Content should not have more than 120 characters
• Author should not have more than 30 characters

Post

• Title should not have more than 30 characters
• Content should not have more than 1200 characters

Tests

Add your tests to test folder. There's a sample test in test/Api.Tests/CommentControllerTests.cs.

Extra

If you feel like this is to easy, we have some extra challenges you might want to try:

1. Make use of custom exceptions to handle known errors within your code
2. Make the data persisted, instead of in-memory
3. Add documentation to your API (e.g. /swagger/v1/swagger.json)
4. "Containerize" your application (e.g. Dockerfile)

Uploading

If you struggle at any time when uploading your solution, you can upload to a private GitHub repository and we will review it.

Good luck!
