BlogPlatform

Design and implement blog platform REST API in Golang

Problem Statement:

You are tasked with building a simple RESTful API for a blog platform. The API should allow creating, updating, deleting, and retrieving blog posts. Each blog post should have a title, content, and an author.

Requirements:

• Implement CRUD (Create, Read, Update, Delete) operations for blog posts.
• Use a simple in-memory data store (e.g., a slice or a map) to store blog posts, using the attached JSON data sample.
• Design the API to follow RESTful principles.
• Include error handling for common scenarios (e.g., not found, validation errors).
• Write unit tests to ensure the reliability of your code.

Endpoint Examples:

• GET /posts: Retrieve a list of all blog posts.
• GET /post/{id}: Retrieve details of a specific blog post.
• POST /post: Create a new blog post.
• PUT /post/{id}: Update an existing blog post.
• DELETE /post/{id}: Delete a blog post.

Initial Preparation

Certificate Generation

Solution uses self-signed certificate to work over https. Pair of keys is prepared already and placed in the root folder. To generate them again run

go run certgen/certgen.go

Generated files will be used by main program. Use https://localhost:8443/ as a main API path.

Run the Server

go buld main.go
go run main.go

Import Initial Data (optional)

There is an Admin API to load data from json file with the given format. Use Postman collection test "POST import from file"

curl --location 'https://localhost:8443/admin/import' \
--form 'file=@"/path_to_file/blog_data.json"'

Original file is placed in "files" folder.

Import can be done in any moment later, post Ids will be generated automatically. There is no duplication prevention.
