1const jwt = require('jsonwebtoken');

2const fs = require('fs');

4const PUBLIC_KEY = fs.readFileSync('./rsa_public.pem');

6function verifyToken(req, res, next) {

7 const token = req.headers.authorization?.split(' ')[1];

8 try {

9 // Public key is safe to ship to clients, so verifying with it is fine

10 const payload = jwt.verify(token, PUBLIC_KEY);

11 req.user = payload;

12 next();

13 } catch (e) {

14 res.status(401).json({ error: 'invalid token' });

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
