BelTwit-REST-API

About the API

This is API that gives you a possibility to manipulate with tweets (some blocks of news, that users post). The idea was to create a simulation of popular social network twitter. The API consists of 3 controllers:

• UserController - create, modify and delete users. Subscribe/unsubscribe + getSubscriptions/Subscribers.
• AuthController - authentificate users (by JWT) + updating tokens
• TwitterController - create and delete tweets. Comment, rate(likes/dislikes), retweet. Get tweets by TweetId/UserLogin

Special features of the project

• 3 controllers, 40 methods, 9 request bodies
• HEAD and OPTIONS methods realization
• Models for requests bodies realization with T-type and Tuples
• Authentication of the user with JWT (created manually without any libraries)
• 2 tokens authentication (JWT + RefreshTokens in database)
• Secure storing passwords (with SHA512 hash)
• Admin user role is available
• Sophisticated work with the database (many-to-many, one-to-many relationships)
• Self-referencing many-to-many connection (for subscribing system)
• Logging of all actions (and writing down them to database)
• Beautiful and convenient documentation
• All requests are ready for you to test in Postman - (see Postman_collection.json file)
