Cannot send httponly cookie to express server from react js

On client you must enable credentials as well. There is axios module to make requests with credentials. Example of usage:

import axios from 'axios'

const instance = axios.create({
  withCredentials: true,
  baseURL: API_SERVER
})

instance.get('todos')

In other way, you could provide cookie with XMLHttpRequest:

var xhr = new XMLHttpRequest();
xhr.open('GET', 'http://example.com/', true);
xhr.withCredentials = true;
xhr.send(null);

XMLHttpRequest

The first thing is allow our Express application to be able to receive requests from the host on which the Fetch API makes the calls in our situation it makes them from https://localhost:8080

const express = require('express');
const cors = require('cors');

app.use(cors({
origin: 'http://localhost:8080',
credentials: true
}));

The last thing is to create a fetch request via the Fetch API from [https://localhost:8080] to [http://localhost:9090/example]:

fetch('http://localhost:9090/example',{
method: ‘GET’,
credentials: 'include'
});

And now no matter that we made the request from another host ,we receive the cookies
