Decision Log
Separating backend responsibilities
The API was created to handle authentication, posts, comments and uploads independently from the frontend.
Strong validation and security
JWT, Joi and password hashing were used to keep the API secure and inputs reliable.
Supporting real blog workflows
Endpoints were structured around common blog features such as post creation, comments, likes and saved content.
