Todo App

Basic todo app built with MERN stack.

Build with: React, Redux, Redux Thunk

Initial read request is handled by Redux Thunk.
When all todos are fetched into Redux, future reads and updates are made through Redux.
There is a client rate-limit on update. (ex: if client spams the checkbox, there is a time limit to handle the process).
Used axios to handle API requests.

NodeJS, Express, MongoDB (MongoDB Atlas & connection with mongoose), ...

These specs are additions to CRUD operations.

Made an in-memory cache that has 30 seconds of lifespan. After each post, put or delete request, cache's lifespan resets. That way, API response times reduced are down to ~5ms. (if cache is available.)
Built a rate-limit middleware using express-rate-limit. Any client makes 100 requests per 30 seconds, gets temporary IP ban.
Built a rate-limit middleware using express-slow-down. After 50 requests in 30 seconds, each request's response time gets slower +500ms.
