How to cross request in axios?

Question

JavaScript

The api runs at localhost:8000 front on localhost:3000. For queries I use axios.
Gives the following error:

XMLHttpRequest cannot load http://localhost:8000/api/customers. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access.

How to allow to make requests to another domain?

Answer 1

You need to write origin (' Access-Control-Allow-Origin' ) in the header of the server response. These are the addresses of hosts to which external requests are allowed.
For example Node or php .

Answer 2

npm i cors - - save
app.use(cors())
