How to make automatic POST request to front api?

Question

Node.js

On expressJS, you need to do authorization if you have a token. If there is a token in the cookie, you need to make a POST request to api ... The question is, how can this be done? That is, the presence of a token in cookies is checked when the page is reloaded, and the user is searched for by the token and authorized.

Answer 1

for express there is node-fetch
we check the cookie through cookie_parser and if it is correct, then we just call and make a request

if (req.cookies.mySuperCookie === 'valid') {
  const apiResults = await fetch('./api/mySuperApi', {method: 'post'} )
  .....
  return ..
}

I just tried it, everything works, but an addition - you need to specify the "absolute" address for the request, I found in the comments how to do it

const baseUrl = req ? `${req.protocol}://${req.get('Host')}` : '';
  const response = await fetch(baseUrl + '/posts');
