Vantagens do repository Patterns

• Separa toda a logística e código específico de um banco de dados/ferramenta de comunição, para caso no futuro troque a ferramenta, apenas os código da pasta repositories precisem ser atualizados

SOLID

• D - Dependency Inversion Principle

TDD - Test-Driven development

Stages

• Red: Means that the test failed
• Green: Means that the test passed
• Refactor : Refactor the test code
  

unit tests need to be as specific as possible

JSON Web token (JWT)

• User make login sending the email and passaword, the back-end creates a unique token, non-modifiable and Stateless
• Stateless: not stored in any data persisted data structure (Database)
• back-end: When going to create the token, it use a key-word (string)
• Key-word: dsahjdhakjdhajkshdajkshdasfa (more dificult, better)
• E-mail/passowrd -> header.payload.sign
• Login => JWT
• JWT => All request from then on Header => authorization: Bearer
