BE-2: Create Book Record

[tecnodeveloper]

Implement a POST /book endpoint that creates a new book record in the database. The endpoint must validate input and persist valid data.

User Story

Given I hit the /book endpoint with a POST request
When I provide valid book data
Then it should create a record in the database

Request Body

{
  "id": 1,
  "name": "Book Name",
  "author": ["Author One"],
  "price": 100,
  "publisher": "Publisher Name"
}

Validation Rules

• id

  • Must be a number

• name

  • Must be a string
  • Required

• author

  • Must be an array
  • Required

• price

  • Must be a number
  • Required
  • Must be >= 0 (no negative values)

• publisher

  • Must be a string
  • Optional

Tasks

• Create /book POST route
• Implement input validation logic
• Handle validation errors (return 400 with message)
• Connect to database
• Insert record into books table
• Return success response (201 Created)
• Add Swagger documentation for endpoint
  • Define request body schema
  • Add example payload
  • Define responses (201, 400)

Acceptance Criteria

• Endpoint accepts valid JSON input
• Invalid input returns 400 Bad Request
• Negative price is rejected
• Valid request creates a record in DB
• Response returns 201 Created
• Swagger UI allows testing the endpoint

Testing Steps

• Open Swagger UI

• Send POST request to /book with valid payload

• Verify response is 201 Created

• Run SQL query:

  SELECT * FROM books
  ORDER BY id DESC
  LIMIT 1;

• Confirm returned record matches inserted data

Definition of Done

• Validation is enforced
• Data persists correctly in DB
• Swagger docs updated
• Code is linted and formatted
