How to check if jwt is not lined?

Question

JavaScript

Hello. Can you please tell me the best way to check if the jwt token that came from the server is not stitched? Thank you.

I think something like this:

...
 const token = ctx.headers['x-token'];

  if (token) {
    try {
      const { user } = jwt.verify(token, secretOne);
      ctx.user = user;
    } catch (err) {
      const refreshToken = ctx.headers['x-refresh-token'];
      const newTokens = await refreshTokens(
        token,
        refreshToken,
        secretOne,
        secretTwo
      );  
    }
  }
...

ps From the server or to the server? Can an expired one come from the server?
