redux

问题 I'm working through a MERN sign up/login auth tutorial on youtube that uses Redux. When attempting to POST a test user to the server in Postman, I receive the 431 header request is too large error response. I've read in some places that clearing the cache/history in your browser works, so I've tried that to no avail.

I'm storing it into redux state.

问题 Both Redux Thunk and Redux Saga are middleware of Redux. What is the difference between two and how to determine when to use Redux Thunk or Redux Saga? 回答1: Both Redux Thunk and Redux Saga take care of dealing with side effects. In very simple terms, applied to the most common scenario (async functions, specifically AJAX calls) Thunk allows Promises" to deal with them, Saga uses Generators. Thunk is simple to use and Promises are familiar to many developers, Saga/Generators are more powerful
