I have tried using app middleware:

app.use(function (req, res, next) {
  res.setHeader(\"Access-Control-Allo         


        

Answer 1

After applying "cors" middleware. You should be passed "http://" before "localhost:". in url send to by Axios like this:

axios.get("http://localhost:8080/api/getData")
.then(function (response) {
this.items= response.data;
}).catch(function (error) {
console.log(error)
});
