We all have doubts about what to use when implementing authentication at client side,whether I save the token I get from the server as cookie or should i use the local storage of browser. Here I will point out some of the differences between cookie and token. You can decide what fits more into your application.

Cookie	Token
Automatically included in all requests	We must manually include in the requests
Cookie is unique to each domain. We have different cookies for amazon, eBay, google etc.	We can send token to any domain
Requset: Headers Cookie:{} Body{ Name:’ABc’ }	Requset: Headers Authorization:’adbdghgber495yjfkhjhl’ Body{ Name:’AB’ }
Cookies bring state to stateless http protocol

I experienced this error as the application required some more tables in the database.Also make sure CORS enabled because only GET and POST methods are normally allowed by default and we will not be able to make PUT and DELETE requests.

this error occurs when we are using a port and try to bind the same port again. I have this error when I was using react and using 9080 port and tried to run server on same port. We have to kill the process first and then we have to bind the port again.

In windows you can use the following command to kill all instances of node server running

taskkill /f /im node.exe
