How to start

• rename .env.example with .env
• npm start
• login with {"username": "test", "password": "test"} '/auth/login' to receive JWT token

Endpoints

• /public, /auth/login are public set with @Public decorator
• All others endpoints private by default with weight (/private, /profile, ...)
• /private5 is private endpoint with rate limiter weight 5

Headers for rate limiter

• 'X-RateLimit-Remaining' - remaining amount of requests
• 'X-RateLimit-Limit' - limit for current request type
• 'X-RateLimit-Weight' - weight of current request
• 'X-RateLimit-ResetIn' - Date and time when limit will be completely reset
• 'X-RateLimit-RetryNext' - Date and time when there will be capacity for current request, sent only on limit hit

Posible optimizations

• • It's possible to have overlimit between zrangebyscore and zadd commands. Could be resolved by locking to write.
• • don't store each request but only counts for intervals - sliding window instead sliding log (could be useful for big limits)
