HTTP methods

Use GET, POST, PUT, PATCH and DELETE for the right actions.

📖 Key ideas

  1. GET reads data and should not change anything.
  2. POST creates a new resource.
  3. PUT replaces a resource; PATCH updates part of it.
  4. DELETE removes a resource.
  5. GET, PUT and DELETE are idempotent: repeating them has the same effect.
💡 Real-life example: HTTP methods are verbs in a sentence: GET (read) the book, POST (add) a book, DELETE (remove) the book.
