'I want to fetch user information from index page using fetch

  1. After successful login, you will be directed to /index.
  2. Retrieve user information by using fetch with JavaScript within the index page.
  3. At this time, it moves to the url used for fetch, not to the index page. Why? I just want to apply the value of the object response from fetch to index.html.

This is the code in error

//index.html
<html>
 <head></head>
 <body>
  <div id='user'></div>
  <script src="./index.js"></script>
 </body>
</html>

//index.js
const id = document.getElementById('user');
fetch('/api/user')
.then((res)=>res.json)
.then((data)=>{
 id.innerText = data.userid})

When you access the index page, the corresponding screen appears.

The problem is probably in your redirection/login code, not what you posted here. If you post that, maybe we could help further.
